Retracted — this record was our error (2026-09-30). Retracted 2026-09-30: no change. This record compared posthog.com/pricing, which states PostHog's monthly free allowances (1M analytics events, 5K session replays, 1M feature flag requests), with our listing of PostHog's deal for Y Combinator companies. The pricing page does not describe that deal; posthog.com/startups says YC companies get a separate deal through Bookface. The free allowances belong to PostHog's free tier, which our PostHog Free listing already states. Source ↗

PostHog's startups handbook page already said on 2026-09-01 that YC teams can use credits for a BAA under the Boost plan and can get up to 4 founder merch packs. The limit of one welcome pack is the startup program's, not the YC deal's. Source ↗
