The Fintech King & BILL’s 20-Year Race To $1 Trillion

In Game of Thrones lore, there was a king who sat fifty-five years atop the Iron Throne. Known as the Wise, the Conciliator, and the Old King, Jahaerys I Targaryen reigned so long because he was fair-spoken, open-handed, and chivalrous. He was also flexible enough to adapt to conditions around him and universally loved by his people. I see similarities between Jaehaerys of House Targaryen, the First of His Name, and the Founder & CEO of BILL, René Lacerte.

Not only has René lorded over fintech for decades, but just as Jaehaerys was a fourth-generation king of Westeros, René is a fourth-generation entrepreneur. The Lacerte name has been synonymous with accounting software since the 1960s. His family built Lacerte Tax Software, which Intuit acquired for $400 million in 1998. Lacerte is to accountants what Targaryen is to dragonriders.

The story of BILL is very much the story of René, but not only René. It’s also the story of Henrique Ceribelli, whom I interviewed for this piece, beginning his career as a PM, to 20 years later running large parts of BILL’s GTM, along with Tara Wellington and Ariege Misherghi, young product leaders looking to push BILL to the next level, whom I also interviewed.

As of today, BILL processes more than 1% of GDP in the United States, and, if you ask René and his team, they are only just getting started. Today, I will break down for you where they came from, how they succeeded, and what their plans are for the future. Let’s dive in!

Familial values

While interviewing René in the lead-up to this piece, one thing became really clear to me: His family background was central to the story. Both René’s parents and grandparents had been in financial services for SMBs and accountants since the 1960s. He didn't stumble onto this problem; it was a problem he inherited at the dinner table.

Henrique recalled to me the company in the early days, when it was operating under the name CashView, and its homepage showed a simple calendar: money in, money out, bills to pay, invoices sent. A simple idea, but one that came from a long-held desire to help small businesses. Those constantly managing the balance between extending payables and bringing in receivables just to survive.

“My dad exemplified that in a very personal way,” he would tell me. “He was born with six fingers, four on his left hand and two on his right. He wanted to play piano, but nobody would teach him. So he taught himself over the course of one summer. He did it by playing every single day until his fingers bled. By the end of that summer, he had developed something remarkable; he could play any song he could hum.” As I listened to René tell this story with warmth and love, I could tell how proud he was of his father.

His mother, too: ”My mom also had a strong appreciation for being present in the moments that matter. Whether it was watching the sunset every night or stopping to look at a flower, she had that quality of actually being there.”

Beyond that, one of the core values at BILL is authenticity, something René traces directly back to his parents. “Even though they came from a different time and held different political views, there was never any judgment about people. They were always welcoming and open. I remember one moment specifically where I must have said something judgmental as a young person, and my dad turned to me and said, ‘Don't be so damn judgmental, René. It doesn't help you in life. You don't have to agree with someone, but do not pass judgment.’”

This culture, the culture of acceptance, respect, and openness, is something that radiated through my interviews for the piece, something we’ll touch on more deeply in a later section.

René’s early career

René not only had a family heritage of small business and accounting, but he also cut his teeth in the tech industry before becoming a founder. First, there was his stop at PwC in 1989, back when they were just Price Waterhouse, where René realized that he wanted to be in “high tech.”

This was followed by a role at CertiData Corporation, and subsequently Intuit, where he spent half a decade setting strategy and leading teams in various PM roles. René would join Intuit when it was just himself and development partner Martin Gates on the team. By the time he left—coincidentally, with Gates, to found PayCycle—the team was over 300 people across four sites.

PayCycle, founded in 1999, was René’s first dive into the turbulent waters of entrepreneurship, where he would spend six years, the first five as CEO, and the final year as CFO. As per his LinkedIn, the major achievements during this time leading the United States first online payroll company were: “Over 25k small businesses; 105 great employees; 5-star awards from PC Magazine and numerous accountant trade publications; customer numbers and revenue doubling every year; partnerships with Microsoft, Intuit, ATX, Digital Insight,” among loads more achievements.

Interviewee Ariege actually worked in customer service at PayCycle with René in her very first role in tech. “I accepted it because I wanted to be around smart people and because I needed the money,” she would tell me. “But I was shocked by how much I loved helping customers. Because it was a payroll company, the stakes were real. If someone's employees don't get paid, somebody can't pay their mortgage. You'd take a call with someone really fired up, and our charter was: help every customer, figure it out, because the stakes are high. That freedom to work the system in favor of the customer gave me a lot of joy. That was the environment René created.”

The DNA of BILL was a carryover of this first venture. The idea of helping the little guy do his best business in the world and to build for what René today calls the ‘Fortune 5 Million.’

Like all great stories, this one would come full circle, with PayCycle eventually being acquired by Intuit in mid-2009.

Day zero decisions

When I asked René to reverse-engineer BILL’s success for me, he broke it down in a very simple way: “I think any software company would say it has to have three different areas of expertise. One is domain, the second would be technology, how you're going to actually execute on the domain, and the third would be how you're going to build customer trust.”

Luckily for the team at BILL, René had a healthy helping of all three: his family, his career trajectory, and the fact that he’d actually felt a large portion of the painful back-office pain while running PayCycle. Like all the best ideas, René was scratching his own itch. Armed with their new market, small team, and shiny mission statement, the question now was, how to find a wedge that would allow them to start making progress.

Incumbents in the space at the time had accounts receivable (AR) covered; FreshBooks had ~500K users and QuickBooks Desktop ~5M, so the opportunity was to enter the market by building automated accounts payable (AP) solutions for small businesses. At the time, this really was category-creating; they essentially had to educate the market that it was something they needed. Their competition was paper checks and online banking, which had simply taken the consumer banking experience and applied it to business without building any of the necessary processes around it.

The decision to focus on AP was a smart one, meaning they could build without any real competitors for years, at which point AR would come into the picture but would be added as part of a much bigger story. In the early days, René and BILL had a few aces up their sleeve that helped drive the company forward.

_{*Note: I am adding this video below not so much because it adds to the narrative, but because it’s great to see René speaking on behalf of BILL seventeen years ago.}

The accounting channel

If your accountant recommends something, you can bet your bottom dollar you’ll consider it. The trust is pre-established. To get accountants even more comfortable recommending BILL, René and the team invested very early in SOC 1 and SOC 2 certifications, non-negotiable given the nature of money movement.

The network

Businesses would receive a payment through BILL.com and then get a very convenient call: ‘Hey there. How would you like to use this to automate your own accounts payable?’ The person on the receiving end already knew who BILL was, so the familiarity led to much higher close rates.

The partnerships

René's instinct was always to partner rather than build everything himself. Their first key partnership came in 2008 with CPA.com, AICPA's division, roughly 18 months into founding the company. Today, BILL serves as the backend for JPMorgan's commercial clients, among many others.

Founded in early 2006, BILL would grow like a rocket within its first few years, until 2008, when the world would be hit by what would be called the Great Recession and the Global Financial Crisis.

The darkest chapter: 2008

Cracks in global markets began to appear in mid-2007, with the collapse of the U.S. subprime mortgage market, and intensified through to its zenith in 2008. This was an incredibly difficult time for BILL, of which I’ll dive into shortly, but it was also a heartbreaking time for René on a personal level, with his father being diagnosed with cancer in February and passing away in September. The Lehman Brothers bankruptcy, a low-water mark in market sentiment, and the stress that put René under coincided almost to the day with a moment of deep personal sadness.

The next month, esteemed Silicon Valley venture firm Sequoia Capital released their ‘R.I.P. Good Times’ presentation, urging founders to make cuts to survive what looked to be a “nuclear winter” in venture funding.

It was at this point that René knew that he had to move. “I read it, and the very next day I went to the head of product and said I thought we needed to act,” René would tell me. “I asked him to think through how we would do it. Then, literally two days later, I went to the board and said I believed we needed to lay off 40% of the company and that, if we did, it would extend our runway by six months. We executed the layoffs, and even after doing that, we came within about two months of running out of money before I was able to close a new round. So it was absolutely the right call, because without it we would have been out of business entirely.”

Layering on top of this emotional pain was the loss of his father, and the fact that the parents of his wife were also sick. “She was flying to Hawaii every three weeks to be with them. We had kids who were five and three years old. As a family, we were seeing each other roughly every three weeks.” How René was able to hold it together through the difficulties was by ‘creating separation’ from the business: “Exercise has been one way to do that. Hiking is another. I also play Ultimate Frisbee once a week when I am in town and available. The point is having things that are just for you; not for the company, not for your family, just for you.”

From survival to 1% of GDP

Two months out from bankruptcy, with a grieving founder, a lean team of 15 early BILL operators went to work figuring out how to survive in a market that had utterly collapsed. What they would decide to double down on would either make or break the burgeoning technology powerhouse.

After hearing and summarizing these interviews, it seemed there were a handful of themes explaining why BILL is still here and processing 1% of GDP today.

1/ Build like you're already at scale

Most startups optimize for the short term, whereas René optimized for what BILL would need long into the future. In a money-movement business, that means compliance, controls, and audit infrastructure built ahead of demand, not after.

”We were never just thinking about what we needed this year; it was always about what we needed for the endgame,” René would tell me. “One example of that is the way we approached moving money from day one. Moving money is a trust-based business… we treated that with the utmost care, operating as though we were already moving 1% of GDP and needed to do it the right way from the start.”

2/ Show product discipline

Henrique originally joined BILL to work on receivables, which was put on ice for a full three years while they focused on dominating the payables product. “The team was small enough that we could only tackle one thing at a time,” Henrique would go on to tell me.

The same discipline can be seen in the fact that they’ve never moved out of financial operations; they could easily have moved into bookkeeping, payroll, tax, but they didn’t. They stayed laser-focused. And again, you see this discipline in their ICP. They are focused on Main Street, not Wall Street (or Sand Hill Road), and it’s remained that way forever.

Staying true to the small business ICP meant that as the product surface expanded, the scope remained the same. It would have been very tempting throughout the journey to release the self-imposed shackles on a defined ICP and start building for the enterprise. But they didn’t; René and the team were building for the little guy.

3/ Leveraging their network effect

Next is a very unique distribution lever BILL has been able to pull on since the very early days: the network effect. This is something I’ve thought deeply about recently, thanks to my mentoring role as part of the Startmate S25 cohort. The company I’ve been working with is FlowGo, a specialized AI agent swarm (dolphins have pods, lions have prides, agents have swarms) for financial operations in Asia. The company is only four months old and growing like a rocket by leveraging the same effect BILL has used for decades.

In the early days, BILL saw that their customers wanted to pay suppliers electronically (ACH); the issue was that suppliers were skeptical of handing their bank details out to random payers. Henrique's idea was to take the receivables product (which they'd already shelved) and make it free. Let suppliers sign up for an account to receive payment without exposing their bank info. As a bonus, they could send invoices through it, too. That free product is now an eight-million-entity network; one billion documents stored; trillions of dollars moved.

To put a direct line through the compounding lesson: when BILL goes on customer visits today, half the room has already been a payee on the platform. The network sells the network.

4/ Own customer touch points

BILL learned the hard way, early, that something as important as customer touch points should stay as close to home as possible. Originally, BILL needed to integrate with every major accounting platform (because the network is software-agnostic by design). They brought in third parties to build those integrations so they could move faster, but the integrations were inconsistent, and customers refused to deal with anyone but BILL when something broke. They pulled it back and rebuilt from scratch—painfully—mid-journey.

They also tried to lean on accounting partners to sell into firms, but without aligned incentives, they found that this GTM didn't scale. To fix this, they built an internal sales team that owns both the sale and the implementation directly with firms. “When the product is complex, and the customer relationship is critical, you need to maintain direct control rather than delegating it out and hoping for the best,” Henrique would tell me.

These experiences led BILL towards only ever outsourcing what's commoditized, but owning what touches the customer.

5/ Acquire if and when necessary

Lastly, in recent years, BILL has not shied away from a strategic acquisition. Divvy was the first move. While René and the team had long owned the bill-pay side of cash-out, they didn’t own the card-side spend. And in this case, rather than build it, they acquired Divvy to bring their customers and intellectual horsepower in-house. Their next addition was the Australian, mobile-first, accounts receivable firm Invoice2go. This strengthened the AR side and gave them greater international reach (especially within APAC).

And most recently, Finmark, which was acquired for an undisclosed amount, giving them new financial planning and forecasting chops. This was a smaller tuck-in to extend BILL into the planning layer above transactions.

With five compounders and 20 years of payment volume, document data, and supplier identity stacked on top of all of it, you start to understand why BILL's AI bet has the data underneath. Which is exactly where we're going next.

AI = Don't automate. Delete.

While every public company scrambles to fit AI into their earnings calls, many are soon to find out that their data and distribution don’t actually help them in the AI world. BILL, on the other hand, has served customers for twenty years, building a rare combo of: 1) a serious data moat, 2) an ever larger trust moat. The goal for BILL is larger than building a handful of helpful workflows and insights. René and the team are looking to delete work altogether.

One easy example that anyone doing business in the U.S. can attest to is the W9 collections agent. In the old world, a customer asked their supplier for a W9, that supplier sent it, and the work helped exactly one customer. With BILL's network, the supplier uploads it once into their free account, and every other customer of that supplier instantly has it on file. The agent's work multiplies across the network. As Henrique would put it, "The agent effectively solved the problem for multiple payers at once because of the network multiplier effect.”

Same logic on invoice coding. BILL learns from how the AP team codes a vendor, but they also learn from how everyone paying that vendor codes it. Collective intelligence example numero uno. Plus, BILL has a global vendor directory built up over years of processing documents. When a new customer joins and drops in a doc, BILL already knows the vendor, payment methods, context, and more. Collective intelligence numero dos.

So, I hear you asking, ‘How does Bill actually build AI internally, you ask?’ Well, allow me to explain. BILL runs its AI strategy across two tracks. First, the transformational layer: rethinking the entire product to be AI-native, not just AI-enabled. Holistic, cross-org, owned by an AI platform team. And second, the feature layer: every individual squad asking how AI changes their corner. Each squad is super lean, ~6 engineers, dedicated to one outcome. No matrix sprawl. No AI czar.

Underneath the two tracks sits a very specific operating model. And it's the same one BILL runs across all of product, starting with planning. Every year, BILL runs a three-tier cycle: a three-year strategic view at the top; a one-year software plan in the middle; team-level objectives at the bottom. Each layer feeds the one below it.

Each year then breaks down into quarters, with each having a six-week pulse check (are we executing, are we hitting the metrics, do we need to pivot?), then a full reset at the end of the quarter. The inputs feeding all of this aren't just product team intuition. Tara walked me through it:

Every initiative at BILL is run by a single dedicated squad. The core is a trio: an engineering manager, a designer, and a PM. Around them sit the engineers, usually about six. Research and product marketing partner in, but don't embed. This is how you set your org to build a world-class product, folks.

By the way, if you’re interested in understanding more deeply the AI usage in the world of finance, BILL released a pretty slick report, which you can enjoy below.

Culture, and why people stay

As a culture-obsessed founder myself, I feel as if I have a reasonable radar for the culture of an organization, along with at least a snippet into the mind of its leader. And although BILL has been through difficult periods in the past—2008, COVID, other rounds of layoffs driven by market forces—I got the real feeling that BILL, under René, was a great place to work. Here are a few notes from the interviews.

Playbook / how you can apply this

• Build like you're already there: René ran BILL as if it already moved 1% of GDP from day one, and that bar set the company.

• Bet the company on accountants: They backed the accounting channel in 2006 and never blinked. Today, over half of BILL's customers still arrive through firms.

• Build the network sideways: Suppliers wouldn't share bank details, so BILL made receivables free. That pivot turned into eight million network nodes.

• Treat trust as infrastructure: SOC 1 and SOC 2 came absurdly early for a startup. In 2008, cloud skepticism was the difference between yes and no.

• Make the CEO the chief customer: René still uses BILL daily and emails product teams about bugs he spots. The obsession trickles all the way down.

• Own what touches the customer: They outsourced integrations and sales early. Both broke. Both got rebuilt in-house. Both then worked.

• Lead with authenticity, even at scale: René cried with the team after the 2008 layoffs and still does at all-hands. Twenty years on, the trust holds.

Summary

Thinking back on the long, successful reign of King Jaehaerys, one thing stood out to me above all else: his ability to endure and determination to survive. The wise old king’s time was full of personal tragedy, political crises, rebellions, and great sicknesses. But through it all, he stayed alive and kept moving forward, something that sounds eerily similar to the protagonist of today’s story.

Business is often the ability to stay alive longer than the competition; out-survive first, then thrive second. BILL has passed their survival stage, and are now set in thrive mode, with 4-5% market penetration, allowing for 1% of the U.S. gross domestic product. But they are not done. Nor are the unsung heroes of this story: small business owners. So long as people are out there taking the risk to build their business, René Ledgerborn, the First of His Name, The Unbankrupt, King of the Fintechs, and Protector of the Fortune Five Million, will be there to serve them.

Fun facts

• Cashboard → CashView, BILL: Cashboard couldn't get the URL. CashView didn't quite stick. The third name turned out to be the trillion-dollar one.

• BILL.com is an OG YouTube channel: If you want to go and browse their back catalog, you can find videos from as far back as 14 years ago.

• The ‘holy shit’ demo: René's dad watched the early demo and said, "Holy shit, René, you've come up with something I've needed my whole life."

• The bank's bank: JPMorgan runs BILL as the backend for its commercial clients, managing financial operations. Yes, that JPMorgan.
