THE PROBLEM

If any of these sound familiar, you’re in the right place

I keep throwing money into ads but users just don’t stick around past Month 1.

My investors want better numbers and I do not know what to try.

My app is growing but I have no idea why people are cancelling. They just disappear.

I got to $10K MRR and I’ve been stuck there for months and I don’t know what’s broken.

Every designer just wants to make it look better. Nobody talks about the metrics behind the design.

My Day-7 retention is embarrassing and I don’t know if it’s the product, the onboarding, or the paywall.

I want to raise a Series A and my metrics suck.

The problem isn’t your idea. It isn’t your product. It isn’t even your marketing budget. It’s that nobody has ever looked closely enough at your data to find the one thing quietly destroying your growth.

I know exactly what you’re going through.

THE MECHANISM

Most agencies design.
Most analysts do data. We do both.

That’s the whole reason apps stay stuck. Founders hire a design agency that makes it prettier, or an analytics consultant who hands them a dashboard. Neither one fixes the actual leak. Here’s how we do it differently.

01

We diagnose before we design.

Before we touch a single screen, we go into your analytics. We install PostHog, watch real session replays of real users moving through your app, and find the exact screen where your retention is breaking. Designing without data is just decoration.

02

We fix the one thing that’s actually broken.

In almost every app we’ve worked on, the biggest retention lever sits in the first 3 to 5 minutes of the experience. We find it, fix it, and measure the before and after cleanly. No guesswork.

03

We tie our upside to your results.

The engagement price is fixed and clear from day one. On top of that, you can add a performance bonus tied to a specific PostHog metric, so if we move the number we agreed on, we earn the bonus, and if we don’t, you don’t pay it. You only pay more once you’ve already won.

Here’s what you get on the call:

A live teardown of your current onboarding flow

Identification of your single highest-impact retention problem

A straight answer on whether we're a fit and whether we can move your number

A clear picture of what the Growth Audit would cover if you want the full diagnosis

This is for you if:

Your app is live and generating revenue

You’re stuck at the same MRR and can’t figure out why

You’re heading into a Series A and need your retention numbers to hold up in the room

You’ve tried redesigns, new features, and more ad spend, and none of it moved the needle
