Project Query Engine

Support hero for Product Analytics: Michael 1st week, Robbie 2nd week.

Retro

• 🟢 HogQL BI features @Gilbert09
  • Great progress! You can now make line graphs for any HogQL query.
  • Still cleaning up this week, plan to launch before Tom goes on holiday.
• 🟡 Convert retention insight @webjunkie and launch trends/lifecycle @Gilbert09 @mariusandra
  • Lifecycle released to our team (today, finally)
  • Retention almost done
  • Trends on standby, waiting for lifecycle to be out, needs more testing.

Hang over items from previous sprint

Insights and BI.

OKR

Project "Finish the darned Query Engine" (Tom, Julian, Marius)

• 🟣 Finish insight HogQL conversion.
  • We're on track this year to convert everything except funnels
  • ✅ Lifecycle - released to our team
  • 🟢 Trends - 95% (to test more and release, done this week?)
  • 🟢 Retention - 90% (missing persons modal, group support, done this week?)
  • 🟡 Stickiness - 0% (not started, likely to finish this year)
  • 🟡 Paths - 0% (not started, likely to finish this year)
  • 🔴 Funnels - 0% (not started, unlikely to finish this year)
• 🟢 Support non-event data sources on HogQL insights (BI tools for data warehouse).
  • Great progress last sprint.
• 🔴 Build tools to measure HogQL query performance, and catch regressions before they hit users.
  • We'll fail at this... again. We keep addressing performance issues as users report, but didn't get to building proactive tooling.

Next sprint

• @Gilbert09 will only work 2 days this sprint
• @webjunkie and @mariusandra will be here until Christmas

High priority

To be revised/discussed during standup, but here are some ideas:

• Release BI to some users @Gilbert09
• Get retention and trends released. @mariusandra
• Great docs for the /api/:project_id/query endpoint, including HogQL and other data exploration nodes. @webjunkie

Low priority / side quests

• Performance work as it comes in.
• Work on the last 3 insights. I'd start with 1) stickiness, 2) paths, and leave 3) funnels to next year.
• Rolling out async queries and, related to that, updating Celery to have more queues.
• Django upgrades

Retro

High priority

• 🟡 Capture-rs @xvello

Team Growth

Retro

Retro items

• Generally how we work: think about how our work aligns with objectives better
• Launch data warehouse pricing https://github.com/PostHog/billing/issues/378 ...delayed by airbyte
• Alert people in UI when an initial billing limit has been sent @xrdt feat: show alert when we automatically apply billing limit upon subscribe #18668
• Look into pinning first step in funnel @xrdt. The product analytics team is working a major insights refactor to make them HogQL backed so we are delaying any feature implementation. Neil gave a number of suggestions on how we might get around this with the current PostHog tooling. There are a number of pitfalls to his suggestions so we settled on a HogQL based solution for now. Tracking activation is really quite a non-trivial task.
• Reinstate recovery billing feature https://github.com/PostHog/billing/pull/409 @raquelmsmith
• Finish invoice split for upcoming invoices @raquelmsmith
• Change MRR per product reporting to be calculated based on usage, not invoice line items @raquelmsmith Discussing here
• Onboarding config step for product analytics and session replay @raquelmsmith feat(onboarding): add product config screen #18720
• Review 3000 onboarding and signup pages fix: Some issues with onboarding for 3000 #18746 @raquelmsmith
• org level info on users feat: add membership level to user / person data #18332 @raquelmsmith
• @xrdt Figure out how to test unsubscribe survey events in cypress feat: Test that 'survey sent' Event is Triggered when Submitting Non-Empty Unsubscribe Survey #18805
• Think about how to better enforce API contracts between posthog FE and billing service @xrdt ?? Should we use graphql?
• Getting logged out when subscribing locally only @xrdt. IDK why I'm being shown as anonymousUser but setting the AUTO_LOGIN env var resolves the surface level issue of having to manually log in every time I try to upgrade.
• It's not quite that simple to ensure that emails are case-insensitive...
• Unset billing limit upon unsubscribe @xrdt. Decided that this is probably a :sparks_joy: moment and can be left as is.

OKR

• 🟢 Objective 1: Nail real-time revenue reporting and forecasting
  • Reasoning: We rely on these metrics to know how we are doing.
  • KR: Amortize invoices properly based on supply dates
  • KR: Split invoices based on item supply dates
• 🟡 Objective 2: Continue experimenting with onboarding and activation metrics
  • KR: Product-specific onboarding performs better than the old onboarding flow
  • KR: 2 experiments for Product Analytics & Session Replay activation metrics each
  • KR: Figure out how to track activation
    • Hogql queries
    • Make queries that "prove" our activation metric, show results for other combinations
      • Bianca has added column that shows retention for non-activated orgs
• ❓ Bonus Objective 3: Better understand what leads to revenue
  • Reasoning: We're still a bit fuzzy about what metrics are leading indicators for revenue.
  • KR: A company scorecard with actionable insights that help us understand where to invest
  • KR: An understanding (doc or dashboard) of how people use multiple products
  • Charles is the primary on this, growth is just here to help

This sprint

High priority

• Activation
  • Finalize activation work & RFC @xrdt
    • RFC is up.
  • Look into emails that happen after initial product analytics and session replay instrumentation, come up with an email to try to get people doing one of the activation events
    • run as experiment
    • @xrdt for product analytics
    • @raquelmsmith for session replay
• Other
  • MRR per product is wrong for feature flags
  • Should we change MRR per product reporting to be calculated based on usage, not invoice line items? Discussing here. Shared doc with Neil.
  • Full testing of the onboarding flow @raquelmsmith
  • Make queries that "prove" our activation metric, show results for other combinations. There are some in this dashboard.
  • We shouldn’t show pricing above $20k/yr on the pricing pages so we don’t “shoot ourselves in the foot” for larger customers who will be paying above that
    • Could be an experiment, does it put people off from signing up because it isn’t as transparent, or feels enterprise-y.

Low priority / side quests

• Think about how to better enforce API contracts between posthog FE and billing service @xrdt ?? Should we use graphql?
  • Had discussed simply using errors from the serializer to make it more clear when there are mismatches in fields being requested from the front-end.
• Add metadata to startup plan customers in stripe
• ctas on billing for customers over 1k/mo
  • Bundling discounts
  • Team training
  • Roadmap chit chat

[brett]

@davemurphysf : @brett is actually a person, just not the one you want. Sprint looks great, though!

[fuziontech]

From now on can we get Brett's final approval on sprints?
