Investors care about scalability, maintainability, and key-person risk. Can the product scale with growth? Can a new team understand and extend the code? Is everything in one person’s head?
Red flags: no tests, no CI/CD, no staging environment, credentials in repo, single points of failure (one DB, one server), and no runbooks. Green flags: documented architecture, automated deployments, monitoring, and a team that can explain tradeoffs.
We look at dependency hygiene (outdated libs, security advisories), data architecture (can they add features without rewriting?), and deployment frequency. Occasional deploys with manual steps suggest higher risk than automated pipelines.
Founders should prepare: architecture diagram, list of critical services and owners, incident history, and a short technical roadmap. Being transparent about tech debt and how you’ll address it builds confidence more than hiding it.
