SOC 2 readiness for seed & Series A founders

TL;DR. First-time SOC 2 is less about a PDF and more about owning an observation window: scoped Trust Services Criteria, named control owners, weekly evidence rhythm, and an auditor engagement you can defend to procurement. This hub sequences Type 1 vs Type 2, cost, timelines, questionnaires, and tooling choices.

Why readiness first

Buyers do not purchase your anxiety—they purchase confidence that security controls are designed and, later, operated. Readiness is the operating system that makes an examination boring in the good way.

ProofWindow focuses on the founder-shaped path: Security-first scope, honest procurement packets while in progress, and a clean handoff into Type 2 observation after Type 1.

Weekly evidence rhythm in one paragraph

Pick owners. Calendar MFA checks, access reviews, vulnerability follow-ups, and vendor updates. Store artifacts with evidence IDs. When the auditor’s PBC list arrives, you export—not invent.

Questions founders ask

What is SOC 2 readiness?

The work to scope your system, assign control owners, operate key controls, and gather evidence so an independent CPA firm can examine you for a Type 1 or Type 2 report.

Should seed startups start with Type 1 or Type 2?

Usually Type 1 first, then a Type 2 observation window—unless a specific buyer requires Type 2 immediately.

How is ProofWindow different from GRC software?

We publish educational guides. We are not a compliance product and do not replace auditors or counsel.

When should we engage an auditor?

Once scope and owners exist and core identity/change controls are running—often during a 90-day readiness push.
