When seed startups should start SOC 2 (deal pressure, not theater)
A softer take: start when a named questionnaire or deal makes the report load-bearing—not as premature theater.

SOC 2 readiness for seed & Series A founders
A practical sequence from deal pressure to Type 1 fieldwork to Type 2 observation—without turning readiness into theater.
TL;DR. First-time SOC 2 is less about a PDF and more about owning an observation window, Type 1/Type 2, and Trust Services Criteria: scoped 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. Glossary →

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.

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.
