Pre-Seed vs. Seed: What Actually Changes for the Technical Co-Founder
The fundraising conversation is dominated by the CEO's perspective. How to pitch, how to structure the deck, how to negotiate term sheets. The technical co-founder's experience rarely gets airtime, and when it does, it's reduced to "make sure the product works for the demo."
That's a shallow view. Each funding stage fundamentally changes what the CTO does every day, what investors expect technically, and what decisions you need to get right. The shift from pre-seed to seed is especially disorienting because it happens fast and nobody tells you it's coming.
Pre-Seed: You Are the Engineering Team
Typical check sizes in Europe (2023): 100K to 500K, occasionally up to 750K from strong angel syndicates or micro-VCs. In the US, pre-seed rounds tend to run 500K to 2M. At this stage, you're raising on a thesis and a team -- maybe a prototype, maybe just a compelling problem statement.
What you're doing day-to-day: Writing code. All of it. You're the backend, the frontend, the DevOps pipeline, the database admin, and the person who gets paged at 3 AM when the server runs out of memory.
What investors expect technically: Not much. The investment thesis is about founders and market. Investors want to see that you can build. A working prototype is a strong signal. A polished architecture diagram is irrelevant.
The decisions that matter:
- Pick boring technology. Use whatever you know best. This is not the time to learn Rust. Speed of iteration is everything, and you iterate fastest in tools you already know.
- Optimize for speed, not scale. A monolith on a single server is fine. I've seen founders spend three months building microservices for an app with zero paying customers.
- Don't over-hire. One bad hire at this stage isn't just salary waste -- it's a three-month distraction while the product stalls.
Your biggest risk: Building too much before validating. The urge to build the "right" system is strong for every technical founder. Fight it. Build the smallest thing that tests your hypothesis. If it works, you'll rebuild after seed anyway.
Seed: The Job Starts Changing
Typical check sizes in Europe (2023): 1M to 4M, with outliers reaching 5-6M for strong teams in hot sectors. The expectation is that you've validated something -- traction, a working product, evidence the market wants what you're building.
What changes in your day-to-day: This is where most technical co-founders get caught off guard. Pre-seed, you wrote code 90% of the time. At seed, that drops to 50-60% and keeps falling. New responsibilities appear fast:
- Hiring. Job descriptions, sourcing, technical interviews, offers. This alone eats 15-20 hours a week when active.
- Architecture decisions with stakes. You now have users, data, and uptime expectations. Decisions about databases, API contracts, and service boundaries have real consequences.
- Process. With 3-5 engineers, how do you prioritize? How do you review code? What's the deployment flow?
- Investor communication. The board wants updates on your technical roadmap. You need to explain technical concepts in business terms.
What seed investors expect:
- A working product with real users, ideally paying ones
- A credible technical roadmap for the next 12-18 months
- Evidence the technology can scale (no fundamental blockers, not that it scales today)
- A hiring plan: next 3-5 roles, seniority, timing
The decisions that matter:
- Invest in CI/CD. Manual deployments stop. Automated testing, automated deployment, staging environments. Every new engineer multiplies deployment risk without a pipeline.
- Start writing tests. Not 100% coverage -- critical paths: signup, payments, core logic. You can't hold the whole system in your head anymore with 4 engineers touching it.
- Document architectural decisions. Lightweight ADRs so engineer number 5 doesn't need a 30-minute history lesson from you for every design choice.
- Plan for your own transition. If you're the only person who can deploy to production, your bus factor is one. Start delegating.
The Identity Shift Nobody Talks About
At pre-seed, your identity is "engineer." Your value is directly tied to what you build with your own hands. It's tangible and satisfying.
At seed, your identity needs to shift to "engineering leader." Your value is measured by what the team builds. The best line of code you write might be a PR review comment that prevents a bug. The most impactful hour might be a hiring debrief, not your IDE.
Many technical co-founders resist this. Some hire a VP of Engineering too early and retreat into code. Others burn out trying to do both -- writing code all day, managing people in the evenings.
The healthy approach: Accept the shift deliberately. Block time for coding -- you should still write code, just not all the code. Block time for hiring, architecture review, mentoring. Stay technical without being on the critical path of every feature.
Series A changes everything again, but that's a different post. The pre-seed to seed transition is where most technical co-founders either grow into the CTO role or get stuck. The ones who navigate it well build teams they trust and let go of being the best individual contributor in the room.
At Conectia, we work with seed-stage CTOs who need to scale their engineering team without compromising on quality. Our senior LATAM engineers are vetted by CTOs who've been through exactly this transition -- so they understand the constraints, the pace, and the stakes of early-stage building.
