The Cycle
Research, hypotheses, experiments, decisions. One loop.
See The CycleExperimentOS
Run a proper experimentation programme
Research, hypotheses, experiments, decisions. One system. Bayesian stats, revenue modelling, iteration chains. Minutes to set up.
Built by Another Web is Possible. Battle-tested on real client work since 2025.
Built for in-house CRO teams
Your whole programme in one place
Airtable, spreadsheets, testing tools that don't connect. Brittle. Knowledge leaves when people do.
Experiment OS: one place for the full workflow. The Cycle (research to decisions). Iteration Chains (what you tried, learned, did next). Revenue modelling. Learning that sticks.
Complete workflow
Everything connects. Nothing gets lost.
One system. Everything linked.
- ResearchCapture evidence and findings.
- HypothesesTurn insights into testable statements.
- ExperimentsRun clean tests with proper setup.
- AnalysisHonest, uncertainty-aware results.
- DecideRecord decisions and next steps.
The Iteration Chain
What you tried, learned, did next.
See the Iteration Chain
Accurate Statistics
Bayesian analysis. Know when you have enough data. No guessing, no premature calls.
Research to Results
Findings to hypotheses to experiments. Full story, not fragments.
Decisions That Stick
What you shipped, why, what you learned. Iteration chains so learning compounds.
Revenue Modelling
Annualised projections, transparent factors. Numbers you can present.
Clear Recommendations
Probability to beat control, expected loss, credible intervals. Defensible.
Built-in Guidance
Step-by-step help. New team members get up to speed.
Privacy by Default
GDPR-minded. Minimal data. Isolated by organisation.
Stop paying more for less
Airtable + spreadsheets cost more and do less than purpose-built.

Frequently Asked Questions
What is experimentation programme management?
The system for running your practice: research, hypotheses, experiments, decisions. Tracks what you tested, why, and what you learned.
How is Experiment OS different from enterprise CRO platforms?
Enterprise: tens of thousands, consultants, long implementation. We're for in-house teams: affordable, no implementation, features you use daily.
Can I use my existing A/B testing platform?
Yes. Use your existing testing tool; manage the rest in Experiment OS.
What’s Bayesian analysis and why does it matter?
Shows probability and uncertainty. No p-hacking, no premature winners. Clear recommendations from actual confidence.
Is this suitable for agencies?
Works for agencies; optimised for in-house teams. Multi-client features on the roadmap.
