By invitation · 30 minutes · Partner-led

A private call with a partner about your experiment program — not a sales pitch.

The Experiment Diagnostic is a working session, not a discovery call. A Tyrell Lab partner spends thirty minutes with you on your activation funnel, your current test backlog, and the experiment you're not sure how to ship. You leave with at least one observation you can act on the same week.

Who's in the room

This call is for a specific kind of growth leader.

We run a senior-only practice, so the diagnostic is curated. The thirty minutes is most useful if you match the reader on the left — and not the one on the right.

This call is for

  • VP of Product or Head of Growth at a Series B–D SaaS company, 50–500 employees.
  • You already run A/B tests, but velocity is stuck or the wins aren't reaching activation.
  • You want a senior partner to pressure-test your roadmap before you commit engineering time.
  • You're willing to share your funnel data and current test backlog during the call.

This call isn't for

  • Pre-seed companies without a live activation funnel and at least three months of test data.
  • Teams looking for a vendor to run hundreds of low-credibility A/B tests on autopilot.
  • Anyone expecting a deck, a generic audit template, or a sales follow-up sequence.
  • Founders who aren't ready to be challenged on the experiment they're already committed to.

The agenda

Thirty minutes, with a defined output.

A diagnostic is a working session. We open the calendar with three things we want to leave the room having done — and one thing we will explicitly not do.

What the thirty minutes covers

  1. Current experiment velocity. A quiet read of how many tests you ship per quarter, what win rate looks like, and where the backlog is stalling. Five to seven minutes.
  2. The top activation friction. You walk us through one step in your onboarding or activation flow that you suspect is leaking. We pressure-test it live against our 47-point Experiment Readiness Audit. Ten to twelve minutes.
  3. One specific audit finding. We surface at least one observation — usually a missing guardrail, a sequencing issue, or a measurement gap — that you can take into your next sprint planning without us. Five minutes.

What we will not do

  • We will not pitch a retainer. If a longer engagement makes sense, we'll say so plainly and leave the next step to you.
  • We will not send a generic "growth audit" deck. The diagnostic output is a written summary tailored to the funnel you brought into the room.
  • We will not share another client's data, even anonymised. Confidentiality runs both ways.

If the thirty minutes produces a clear next experiment to ship, we tell you. If it doesn't, we tell you that too — and you keep the written summary regardless.

What happens after you book

Three steps, no friction.

There is no qualification form, no SDR call, and no pre-call worksheet. You book the slot, we send a confirmation, and the partner shows up with notes.

  1. 01

    Confirmation, within an hour

    You receive a calendar invite from a Tyrell Lab partner — not a sales operations inbox — within sixty minutes of booking. The invite includes a short, optional note about anything useful to have open during the call.

  2. 02

    The call itself, partner-led

    Thirty minutes, video, on calendar. A senior partner runs the session. No slide deck. We work from the agenda above, and we leave at least five minutes for your questions at the end.

  3. 03

    Written diagnostic, within 48 hours

    You receive a one-page written summary covering the audit findings, the recommended next experiment, and a clear note on whether a longer engagement would help — or wouldn't. The summary is yours whether or not you continue working with us.

The record

Four numbers, before you book.

We are deliberately not a hundred-slide pitch deck. These are the verified figures we are willing to put in writing before the call.
