A buyer says the words. The first security questionnaire or MSA clause that demands a report is the most common starting gun — and the most expensive one, because the deal now idles while compliance catches up.
You start holding data that matters. Production access to customer PII, financial records, or health data means the next serious prospect will ask. Starting alongside the data beats starting alongside the deal.
Diligence is on the calendar. Security posture now shows up in fundraising and M&A data rooms; SOC 2 before Series A walks through why a report sitting in the data room reads so differently from a promise of one.
The Type 2 observation window elapses in real months no matter when you begin, so a late start converts directly into deal delay — the one currency a startup cannot mint more of. Begin early and the window runs quietly in the background while the product ships; the report exists before anyone demands it.
Early is also simply easier: fewer people to onboard into controls, fewer systems to scope, less historical mess to clean up. A five-person company installs habits; a fifty-person company runs a change program. Costs, sequencing, and what to buy when are broken down in SOC 2 compliance for startups.
Pre-product, with no customer data and no buyer pull — probably. Keep baseline hygiene in place (SSO, MFA, access discipline) and kick off the formal program when a trigger sits about a quarter away.
Compress readiness hard, get a Type 1 quickly, open the Type 2 window immediately, and give the buyer dated milestones. Transparency about a real timeline keeps most deals alive.
