Latest / The Series A Show with Fexingo: Early-Stage Funding, Pitch Decks, and Startup Milestones / The Series A Hidden Cost of Technical Debt
Transcript
- Lucas: Most Series A founders think they’re raising money to grow sales, but half of them are actually raising money to pay off the interest on their technical debt. It’s a quiet killer. I was looking at a recent term sheet for a B2B SaaS company that had doubled its recurring revenue in twelve months, yet its engineering burn rate had tripled. The reason? They’d shipped so fast during their seed round that the underlying codebase was essentially spaghetti. Luna: That sounds like a classic trap. You build the thing you need today, but tomorrow it becomes the thing that breaks everything. Did this specific company have a warning sign before the Series A? Lucas: Oh, absolutely. Their customer support tickets related to bugs were up forty percent quarter-over-quarter. But the founder told the lead investor that those were just growing pains. The investor bought it because the gross margins looked fine on paper. What they didn’t see was that every new feature took three times longer to build than industry standard. That’s invisible drag until it’s too late. Luna: It’s interesting that the investor missed it. Usually, data room reviews catch these kinds of inefficiencies. Or do they just assume the engineering team can fix it later with the raise? Lucas: Exactly. There’s this assumption that money solves engineering problems. But if your architecture is flawed, throwing more developers at it just creates more complexity. I read a report last week from a venture research firm showing that startups with poor code quality take twice as long to onboard new engineers. That means your product roadmap stalls while you’re busy hiring and training instead of innovating. Luna: So the velocity drops even as headcount goes up. That’s a dangerous spiral for a company trying to prove product-market fit at scale. Lucas: Right. And here’s the kicker: it affects your valuation multiple. If you’re comparing yourself to peers who have clean stacks, your higher operating expenses make your margins look worse. In today’s market, where growth is being priced more conservatively, inefficient operations get punished harder. We saw a couple of mid-cap tech stocks dip this week partly because their guidance reflected rising infrastructure costs. Luna: I noticed that with some of the smaller AI plays. They promised rapid deployment but struggled with latency issues. Was that purely technical debt or something else? Lucas: Often both. But let’s stick to the core issue: technical debt isn’t just about messy code. It’s about decisions you made to move fast that now require significant investment to reverse. Think about API integrations that don’t scale, or data structures that lock you into a specific cloud provider. These aren’t just developer complaints; they’re board-level risks. Luna: So how do founders spot this early? Is there a metric they should be tracking besides bug counts? Lucas: Look at deployment frequency and change failure rate. If you’re deploying daily but rolling back ten percent of the time, you have a problem. Another one is mean time to recovery. How long does it take you to fix a critical outage? If it’s hours instead of minutes, your system is fragile. Investors are starting to ask for these DevOps metrics in their due diligence questionnaires. Luna: That makes sense. It shifts the conversation from subjective 'is the code good' to objective 'how stable is our delivery pipeline.' Much easier to benchmark. Lucas: Precisely. And it forces the founder to be honest. You can’t hide behind vague promises when you have hard numbers showing your release cycle is slowing down. It’s a leading indicator of operational health. Now, obviously, not all debt is bad. Some of it is strategic—like building a proprietary algorithm that gives you a moat. But most of it is accidental, born out of haste and lack of oversight. Luna: Strategic versus accidental debt. I like that distinction. Strategic debt buys you time to capture market share. Accidental debt just buys you future headaches. Lucas: Spot on. The key is to budget for paying it down. Successful Series A companies allocate fifteen to twenty percent of their engineering capacity to refactoring. If you’re spending one hundred percent on new features, you’re borrowing against your future self at usury rates. Eventually, the interest payments stop fitting in your budget. Luna: That feels counterintuitive to founders who are terrified of stopping growth. Telling them to slow down to go faster later is a hard sell. Lucas: It is. But I’ve seen it work when framed correctly. You don’t say 'we need to refactor.' You say 'we need to reduce churn caused by performance issues.' When you tie technical improvements to revenue retention, the CFO listens. It’s no longer an engineering expense; it’s a revenue protection strategy. Luna: That’s a powerful reframe. Connecting code quality directly to customer retention changes the priority list overnight. Lucas: Exactly. And it helps with hiring too. Top-tier engineers hate working on legacy messes. If you show them a plan to improve the tech stack, you attract better talent. Better talent builds better products. It’s a virtuous cycle. Conversely, a toxic codebase repels good people, leaving you stuck with junior devs who write more debt. Luna: So it’s a self-reinforcing loop either way. Good or bad. Which brings me back to the fundraising angle. Do Series A investors really dig into this level of detail? Lucas: They are increasingly doing so. Especially in software-heavy sectors. I spoke to a partner at a major fund last month who said they now require a technical due diligence report from third-party firms before writing checks above five million dollars. They want to know if the CTO knows what they’re talking about and if the infrastructure is scalable. Luna: That raises the bar significantly. Founders can’t just wing the technical questions anymore. They need concrete evidence of stability. Lucas: Right. And that evidence isn’t just a demo. It’s logs, metrics, and architectural diagrams. It’s proving that you can handle ten times your current load without collapsing. In this market, resilience is valued over raw speed. We’re seeing valuations compress for companies that look pretty on the surface but have shaky foundations. Luna: It reminds me of the housing market crash. Beautiful facades, rotten frames. People got burned because they only looked at the paint job. Lucas: Perfect analogy. And unlike houses, you can’t easily swap out the frame once the tenants are moved in. Migration costs are huge. So you have to get it right upfront. That’s why I always tell founders: build for the next stage, not just the current one. Design your systems assuming you’ll have a thousand users, not just a hundred. Luna: Anticipatory design. It requires more discipline in the beginning, but it saves massive amounts of pain later. Lucas: Discipline is the keyword. Most founders are naturally chaotic. They want to launch yesterday. Instilling discipline in engineering requires strong leadership from the CTO and alignment with the CEO. If the CEO doesn’t respect the process, the engineers will be pressured to cut corners. Luna: So it’s really a culture issue as much as a technical one. Culture eats strategy for breakfast, and probably code quality for lunch too. Lucas: You could say that. And it’s worth noting that this applies beyond just software. Supply chain decisions, vendor contracts, legal structures—all of these carry technical debt analogues. It’s about the cost of future flexibility. Luna: That broadens it nicely. It’s not just about lines of code; it’s about any decision that restricts your options down the road. Lucas: Exactly. So when you’re preparing for your Series A, ask yourself: what am I ignoring now that will come back to haunt me in eighteen months? Be honest. Because your investors will find out eventually. Luna: And hopefully they’ll find out that you already have a plan to address it, rather than catching you off guard. Lucas: Always. Transparency about your challenges, paired with a clear mitigation strategy, is far more valuable than pretending everything is perfect. It shows maturity. And maturity is what gets you funded in this environment. Luna: Maturity over hype. I think that’s the theme for this whole year of investing. Lucas: I agree. The era of growth at all costs is cooling. Now it’s about sustainable, efficient growth. And that starts with fixing your foundation. Luna: So, if this conversation has been useful for your own journey or your team’s strategy, consider supporting the show. Buy me a coffee dot com slash fexingo. Lucas: Yeah, it helps keep these deep dives ad-free and consistent. Thanks for listening. Luna: We appreciate it. Now, back to the main thread. Lucas: One final thought on that sustainability point. Many founders think sustainability means cutting costs. But sometimes it means investing in quality to prevent waste. Refactoring is cheaper than rebuilding. Choosing the right cloud provider now is cheaper than migrating later. It’s all about optimizing for total cost of ownership, not just immediate cash flow. Luna: Total cost of ownership. That’s a finance term applied to engineering. Smart. Lucas: It bridges the gap between the two worlds. If you speak the language of the CFO, you can justify the engineering spend. And that’s exactly what you need to do to secure a healthy Series A. Luna: So, the takeaway is: measure your debt, budget for its repayment, and communicate its impact in business terms. Lucas: Measure, budget, communicate. Three simple steps that separate the survivors from the casualties. Luna: Hard to argue with that logic. It’s practical, actionable advice for anyone in the trenches right now. Lucas: It is. And as we move deeper into Q4, with all the pressure to close deals before year-end, taking a step back to assess your technical health might be the best investment you make. Luna: Pause to assess. Sometimes the fastest way forward is to stop running in circles. Lucas: Exactly. Don’t let the urgency of the moment blind you to the structural integrity of your business. Build something that lasts. Luna: Build to last. I’ll leave that with you. Until next time.
