47 questions your next investor will ask about your stack

Table of contents

What’s inside the 20-page field guide

Seven sections, 47 items. Tick what you have. Circle what you don’t. The unticked items are your roadmap.

  1. 01

    Architecture Foundations

    The codebase your future Series A will inherit. Modular monolith vs microservices, environments, deploy frequency, backups.

    7 items
  2. 02

    Auth & Trust

    The architecture of your security posture. Managed auth providers, session strategy, MFA, audit logs, secrets handling.

    6 items
  3. 03

    Data & Billing

    The edge cases where money and trust break. Stripe setup, webhook idempotency, refunds, dunning, dispute trails.

    7 items
  4. 04

    Data Quality

    Whether you can trust the numbers your dashboards show. Source-of-truth boundaries, event schemas, backfill discipline.

    6 items
  5. 05

    Performance & Scale

    The layer where products fail invisibly. Search performance, query budgets, caching, cost visibility, load testing.

    7 items
  6. 06

    Operational Tooling

    Whether your team can operate the platform without engineering. Admin console, refunds without engineering, on-call playbooks.

    7 items
  7. 07

    Compliance Posture

    The section that most often surfaces unwelcome surprises at Series A. GDPR, sector regimes, SOC 2, incident response, diligence-readiness.

    7 items

Built from production audits

Every item started as a finding in a real codebase

An unindexed query behind a search bar. A webhook with no idempotency key. A secrets file sitting in the repo. The checklist gives you the questions we ask; the answers are already in your stack.

Who it’s for

Built for the seed-to-Series-A stretch

01

Newly funded founders

You closed a seed or Series A in the last 90 days and you’re deciding whether to hire engineers in-house, engage an agency, or push the founder MVP further.

02

Founders preparing for Series A

Your investors will run a tech audit at the next round. This checklist tells you what they’ll look for before they look.

03

Operators inheriting a stack

You acquired a company, joined as CTO, or stepped into engineering leadership. You need a structured way to map what you’ve inherited, before something breaks under load.

Free vs paid

The checklist is free. The audit is the paid version.

The checklist is the self-assessment we would run on your stack. The Tech Audit is us running it for you, on your actual code, with a written verdict.
