we unpack one of the fastest built experimentation engines i've seen!! In this episode, I sit down with Kameron Tanseli (Growth Engineering) and Rosie Hoggmascall (Growth & Product) from Fyxer.ai and we retrace the steps of building a 500+ /year experimentation program.


We go deep into:

  • Why their first onboarding experiments actually made things worse
  • The tooling shift from PostHog to GrowthBook (and why it mattered)
  • How decentralized ownership (no PM, no heavy process) unlocked serious speed
  • Why every engineer acts like a founder
  • How Slack transparency builds experimentation culture
  • Using AI agents to automate experiment reporting, analysis, and cleanup
  • What “time to value” really means in an AI product
  • The emotional side of onboarding (“inbox shock”) and how it impacts retention
  • How to prioritize when you’re scaling from 5 → 70+ people

We also explore:


  • ➤ The difference between growth and product prioritization
  • ➤ How to surface insights across support, sales, and product
  • ➤ What’s still impossible to automate in experimentation
  • ➤ The tracking challenges of building inside Gmail and Outlook and of other AI tools
