What founders should decide before writing a single line of code

By Juan Martinez • Dallas–Fort Worth • Updated Feb 11, 2026

1) Who exactly is this for?

“Small businesses” is not a target. “Early-stage ecommerce brands doing $50k–$200k/month” is. You want a specific user profile, a clear problem they feel today, and a reason they would switch from what they’re doing now. If this isn’t clear, your architecture won’t be either.

2) What does version 1 need to prove?

An MVP isn’t a “lite version of the full vision.” It’s an experiment. Decide what the product must prove, the minimum feature set required, and what can wait. Most teams overbuild because they design for scale before they validate demand.

3) What constraints exist?

Constraints aren’t limitations — they’re design inputs. Clarify timeline, budget ceiling, regulatory requirements, must-have integrations, and the technical skill level of the team. Systems designed without constraints tend to be over-engineered.

4) Build vs buy decisions

You do not need to build everything. For each major component ask: Is this core IP? Is it commodity? Is there a reliable SaaS alternative? Authentication, billing, search, messaging, and analytics often don’t need to be custom on day one.

5) What happens if this succeeds?

Even at MVP stage, think ahead. If usage grows 10x, where would the system break? Which components need flexibility? What can stay simple? You don’t need enterprise architecture — but you should avoid obvious dead ends.

6) Who owns technical decisions?

If you don’t have a technical co-founder, decide who validates vendor proposals, reviews architecture, and pushes back on unnecessary complexity. Many founders rely entirely on a dev shop without a neutral technical lens — that’s risky.

The pattern I see most often

Founders start coding before scope is clear, assumptions are documented, trade-offs are discussed, and roadmaps are sequenced. That leads to rewrites, vendor frustration, missed timelines, and overspending. Clarity before code prevents that.

If you’re unsure where to start

You don’t need a long engagement. Often, a focused architecture + roadmap process is enough to define scope, choose a stack intentionally, identify risks, and create a 90-day build plan.
