About Experiment OS
We built this because nothing else existed.
Every agency running serious experimentation programmes was improvising their infrastructure. Airtable for tracking experiments. Spreadsheets for analysis. Testing platforms that don't talk to anything else. No single source of truth. No proper workflow.
We're Another Web is Possible, a UK consultancy specialising in ethical CRO. After years of building our own frankenstein stack, we built the thing we wished existed: an actual operating system for experimentation.
We use this to run AWIP's client work. It's battle-tested on real projects, real clients, real deadlines. Now it's available to other agencies who are sick of improvising.
How we're different
Ethical by design
No dark patterns in the toolkit. No manipulation metrics. We won't build features that harm users, even if they'd increase conversions.
Honest statistics
Bayesian methods that show uncertainty. No p-hacking. No premature winners. If you can't prove it beat control, we won't let you call it a winner.
Built by practitioners
This isn't VC-funded enterprise software. It's built by people who actually run experiments for clients and got sick of the tools available.
10% for a better world
We give 10% of whatever people pay - not profit, revenue - to organisations working to make the web and the world better. Digital rights advocacy, accessibility improvements, open source projects, LGBTQ+ rights, investigative journalism.
When you subscribe, you choose where your contribution goes. We track and publish exactly where the money goes in real-time. No corporate PR bullshit about "giving back". Just direct support for causes that matter.
This isn't charity. It's paying into the infrastructure and movements that make ethical software possible. We benefit from these organisations' work. So do you.
Stop improvising. Start experimenting properly.
