90-day SOC 2 Type 1 checklist for SaaS founders

TL;DR. In 90 days most seed SaaS teams can scope Common Criteria, assign control owners, stand up MFA and access reviews, collect a starter evidence pack, pick an auditor, and complete Type 1 fieldwork—if leadership treats readiness as a weekly operating rhythm, not a side quest.

Days 1–30 — Scope and owners

Days 31–60 — Operate the basics

Days 61–90 — Auditor and fieldwork

If you miss a week, slide the calendar—do not compress evidence into a heroic weekend. Auditors sample operating rhythm.

Questions founders ask

Do we need a GRC tool in the first 90 days?

Not strictly. You need owners, evidence, and an auditor. Tools help when integrations save weekly hours.

Who should own the checklist?

A single accountable lead (often a founder or Head of Eng) with named control owners.

What if we miss day 90?

Extend honestly. Do not fabricate operating history.
