    • Parquet export of events and person snapshots to your own S3-compatible bucket, exactly once per window.
    • Drop-in ingest for PostHog (/capture, /i/v0/e, /e, /batch, /decide, /flags?v=2) and Segment (/v1/*).
    • @atrix.dev/posthog-compat, the posthog-js API on the Atrix web SDK.

  2. Revenue and Findings

    • Revenue connectors for Stripe, RevenueCat, App Store Server Notifications V2 and Google Play real-time notifications, each verified with the provider's own proof.
    • Normalised revenue events with ECB currency conversion, $revenue events on the paying person, and revenue insights: MRR, ARR, MRR movements, ARPU, LTV by cohort, refund rate.
    • setRevenueCustomer in the web, React Native, Node, Python and Go SDKs.
    • Findings: seasonal anomaly detection on certified metrics and top events, root cause by segment, grounded write-ups, delivery to Slack, email or a signed webhook.

  3. Flags, experiments, session replay and Ask

    • Feature flags with per-environment configuration, local evaluation in the Node, Python and Go SDKs, and bucketing proven identical across languages.
    • Experiments with sequential, fixed-horizon and Bayesian analysis, CUPED, SRM checks, guardrails and a power calculator.
    • Session replay: rrweb on the web, native wireframe recorders for iOS and Android, React Native bridging, one player for all of them.
