Two goals. Three levels of involvement.

We set up the process, the governance, and the statistics, and we can run the whole program for you. Wherever your users make a choice, you can test it: on your website, in your app, or in acquisition (ad creative, ad copy, landing pages, offers).

Your goal

Build

You don't test yet, or you test without a system. We set up the process, tools, governance, and team structure to test continuously.

Scale

You already test. We raise your velocity, your statistical rigor, and the value each test brings to the roadmap.

Our involvement

Guide

We audit, design, and coach. Your team runs the program.

Co-run

We work alongside your team and share design, build, and analysis.

Run

We operate the program end to end. One contact on your side keeps it aligned with business goals.

The building blocks

CRO audit
Roadmap and prioritization
Test design and mock-ups
Development and QA
Statistical analysis
Web and app analytics
Tracking plans
Insight repository
Team training

Most engagements start with an audit of your data, funnel, and team, ending with a prioritized test roadmap.

Three ways to work together

Retainer

A fixed schedule over a set period, for example three days a week for six months. Suited to an embedded experimentation lead.

Pay-as-you-go days

Buy a volume of days for the year and draw from it task by task. An A/B test from design to analysis takes 3 to 5 days, an audit around 8. You get time reporting to the hour and pay only for work delivered.

Package

A defined deliverable at a fixed price, whatever time it takes us. Suited to audits, program setup, and training.

Sectors we know

E-commerce and retail
Travel and hospitality
Banking and telecom
Gaming and lottery
B2B and tech
