After two failed startups, David García Aceves co-founded Digitt to help prime Mexican consumers refinance high-interest credit card debt. By learning from his mistakes about founder-market fit and market size, he and his co-founder raised $60M in equity and debt. Their success came from relentlessly networking with experts, building lean from first principles, and proving a profitable lending model to investors.
Key takeaways
- Don't start a company you aren't passionate about; the work is too hard.
- Ensure your target market is large enough for venture-scale returns. A small number of potential customers is a major red flag.
- When you lack industry expertise, aggressively network to recruit advisors and early investors who fill your gaps.
- For lending businesses, separate your fundraising asks: equity for operations and growth, debt for loan capital.
- Your personal frustrations can be the source of your best startup ideas. Founder-problem fit is a powerful advantage.
- Reverse-engineer problems from first principles. Your "naivety" can be a competitive edge against slow-moving incumbents.
Your Pain Is Your Platform
David García Aceves grew up in a middle-class family in Guadalajara. His childhood was happy, but a defining moment came when he was 10: his father’s business went bankrupt. Watching his parents struggle with the fallout gave him a visceral, lifelong understanding of financial instability.
This experience didn’t just shape his character; it became the source of his "founder-problem fit." Many VCs look for founders with an "unfair advantage." Often, that advantage is having felt the problem you’re solving more acutely than anyone else. David’s early exposure to financial hardship wasn’t a hurdle to overcome; it was the raw material for his future company, Digitt.
His ambition was further fueled by attending a university where he was surrounded by peers from wealthy backgrounds. He wasn’t resentful; he was analytical. He saw what was possible in Mexico and started decoding the patterns of the successful people around him. He decided he would become an entrepreneur.
Mistake #1: Building Something You Don't Care About
After a stint at IBM convinced him the corporate world wasn't his path, David jumped into his first startup, Adactivo, an out-of-home advertising company. The market seemed promising, but the work felt hollow.
“You shouldn’t start a company you’re not passionate about,” David reflects. This is a critical lesson. When the inevitable downturns hit—a co-founder leaves, a product launch fails, you’re running out of cash—market opportunity alone won’t get you through it. You need a deeper, almost obsessive, connection to the mission.
How to Avoid This Mistake: A Founder-Passion Fit Checklist
The 10-Year Test: Can you see yourself working on this problem, in this industry, for the next decade? Even if this specific company fails? · The Dinner Party Test: Are you genuinely excited to talk about your industry and its challenges, or do you dread being asked what you do? · The "Reading for Fun" Test: Do you find yourself naturally consuming information about this space in your free time? · The Problem-Love Test: Are you more in love with your solution, or are you obsessed with the problem itself? Solutions are disposable; obsession with a problem fuels iteration.
David’s lack of passion for advertising made Adactivo’s failure an inevitability. It was a lesson he paid for with his time and energy.
Mistake #2: Targeting a Market That Can't Support Venture Scale
His second company, PagoSafe, was a fraud-prevention startup. This time, the idea was rooted in a real problem he’d experienced. It was closer to his interests in fintech. But it had a fatal flaw: the market was too small.
David learned that in Mexico, the entire potential customer base was only about 50 banks. Compare this to the thousands of banks, credit unions, and fintechs in the United States. To make matters worse, many of those 50 banks didn’t issue the retail cards PagoSafe was built to protect. The total addressable market (TAM) was tiny.
When he finally got in front of potential bank customers, they told him it made more sense to build it themselves. The business wasn’t viable.

From Rock Bottom to a Real Insight
After PagoSafe failed, David was adrift for 18 months with no income. His personal credit card debt ballooned, with interest rates climbing to a staggering 70%. The problem he’d been circling with his startups was now his own personal crisis.
The breakthrough came while listening to a podcast episode with Renaud Laplanche, founder of LendingClub. Laplanche described his frustration seeing his money earn 2% in a savings account while his credit card charged him 18%. David wasn’t just being charged 18%; he was facing 70% APRs. He saw the same arbitrage opportunity, magnified by the realities of the Mexican market.
This is where Digitt was born. The mission: refinance credit card debt for Mexico's prime and near-prime consumers—people with good credit and income who were still being gouged by traditional banks.
How to Build When You're Not the Expert
David and his co-founder, Manuel Alvarez, had the vision and the personal drive, but they had zero experience in consumer lending. This "naivety" became their greatest asset. Unburdened by industry dogma, they approached the problem from first principles.
Step 1: Reverse-Engineer the Business Model
They asked a simple question: How can we offer lower rates and still build a profitable business? Instead of accepting high default rates or expensive marketing channels as a cost of doing business, they built their underwriting models, customer acquisition strategies, and operational infrastructure from scratch to be brutally efficient. Every dollar they saved in operational costs could be passed to the consumer as a lower interest rate, creating a powerful competitive advantage.
Step 2: Aggressively "Recruit" Your Knowledge Gaps
David and Manuel knew they needed to learn from the best. They became relentless networkers, sending targeted, intelligent cold emails to senior figures at pioneering fintech companies like LendingClub and SoFi. They didn’t ask for jobs or money; they asked for advice.
Subject: Question re: your work on [Specific Project] at [Company]
My name is David García, and I'm the founder of a startup in Mexico tackling consumer credit card debt. Your work on [Specific Project, e.g., "the early underwriting models at SoFi"] was foundational.
I’ve been trying to solve a similar challenge in our market, specifically around [one-sentence description of a specific, non-obvious problem]. My question is: When you were first starting out, how did you think about balancing [A] vs. [B]?
Any insight you have would be incredibly valuable. Totally understand you're busy, so no pressure at all.
This persistence paid off. They secured angel investment and advisory support from SoFi's former president and CFO, instantly giving them credibility and a deep well of industry knowledge.
Fundraising: The $60 Million Equity and Debt Strategy
The title of the source article mentions a $60 million raise in equity and debt, a crucial detail missing from the body. For a lending company like Digitt, this dual-track fundraising is standard, but it’s a critical lesson for founders in any capital-intensive business.
Equity vs. Debt: Two Tools for Two Different Jobs
Equity: This is the money you raise from venture capitalists in exchange for ownership in your company. You use this capital to pay for operations: salaries for your engineers, marketers, and data scientists; your tech stack; and your office space. This is the capital you use to build the machine. A typical pre-seed or seed round for this kind of business might be $1.5M-$3M. · Debt: This is the capital you borrow to function as the raw material for your product. For Digitt, the "product" is loans. They raise large lines of credit from institutional lenders and use that money to refinance their customers' debt. This capital isn’t for hiring; it’s the inventory on their balance sheet.
When you pitch a lending business, you are making two distinct cases to two different types of investors. VCs (equity investors) are betting on your team, tech, and growth potential. Credit funds (debt investors) are betting on the quality of your underwriting—your ability to get the money back with interest.
To raise the $60M, David and his team had to prove they had a machine that worked. They likely started with a smaller equity round to build the product and lend out a small amount of money (perhaps their own, or from a small initial debt facility). They would have tracked their loan performance obsessively, proving low default rates and profitable unit economics. With that data, they could go to larger debt providers and VCs to pour fuel on the fire.

Frequently asked questions
- What is the difference between raising equity and debt for a startup?
- Equity financing is selling ownership stakes (shares) in your company to investors for cash. Debt financing is borrowing money that must be repaid, often with interest. For a fintech lender like Digitt, equity funds operations (salaries, tech), while debt provides the capital for its loans.
- What does 'venture scale' mean for a market size?
- Venture scale means the total addressable market (TAM) is large enough to potentially generate a 100x return for early-stage investors. This typically means a market worth billions, not millions, ensuring that even capturing a small percentage results in massive revenue.
- How can I contact senior industry experts for advice if I don't have a network?
- Use 'smart cold outreach.' Send concise, respectful emails or LinkedIn messages that show you've done your homework on their work, ask one specific, insightful question, and make it clear you're seeking advice, not a job or investment.
- What are 'prime' and 'near-prime' customers?
- These terms classify borrowers by credit risk. Prime customers have excellent credit scores and financial stability, making them low-risk. Near-prime customers are just below that top tier but are still considered reliable borrowers, unlike subprime customers, who have poor credit.
