Every decision
is a hypothesis.
We built the notebook for it.
optimiser.pro is an experimentation OS for product-ops teams — run A/B tests, ship feature flags, and watch funnels without a $40k/yr enterprise contract.
The tools cost more
than the experiments.
Most product-ops teams are stuck choosing between a $40k Optimizely contract, a clunky homegrown setup, or no experiments at all. We think there's a fourth option.
Enterprise tools price out the people who need them most
The teams with the tightest margins — indie products, bootstrapped SaaS, in-house growth squads — are the ones who most need to test before shipping. $40k annual seats don't scale down.
Homegrown experiment frameworks rot in six months
Every product team builds its own. None of them get maintained. The person who wrote it leaves. The CSV of results sits in someone's Dropbox.
"Just use GA4" isn't an experimentation strategy
Event analytics tells you what happened. It doesn't tell you what to ship next. Significance, holdouts, and feature flags need their own layer.
Dashboards optimised for data scientists, not PMs
The tools that do exist are built for statisticians. PMs want to know: ship it, kill it, or keep running? Not read a confidence-interval essay.
We wrote this from the other side of the keyboard.
optimiser.pro was built by a product-ops team (sanjow.ventures) for its own products — topup.ae, wepdf, checkin. We were the team with a homegrown setup that rotted. We're the ones who couldn't justify Optimizely.
So we built the thing we wished existed. Fast, opinionated, priced like you're running experiments — not signing procurement deals.
“We had three different experimentation tools stitched together. The CSVs lived in Dropbox. We shipped two bad variants in a month because nobody knew which one had won. optimiser.pro fixed that in a week.”
Hypothesis to shipped variant,
without ceremony.
A CLI, a dashboard, and a JS snippet. That's the whole surface area. You don't need to learn a new statistical framework — just describe the change and watch it run.
# write it like a note to yourself $ optimiser new "cta_copy" variant: "Start free →" hypothesis: "action verb lifts CTR"
const cta = optimiser.flag( 'cta_copy' ) ?? 'Get started';
# live view, updated every 60s $ optimiser watch cta_copy lift: +4.8% · p=0.02 verdict: ship it
# ship the winner $ optimiser ship cta_copy ✓ rolled to 100% ✓ losing variant archived
Dense when you want it.
Quiet when you don't.
Every surface is designed for the PM's question — “can I ship this?” — not the statistician's essay. Significance is shown, not buried. Annotations are first-class. Kill-switches are one click.

Product-ops teams who
picked the fourth option.
We shipped 14 experiments in our first month on optimiser.pro. Our previous stack got us 3 in six months. Same team, same roadmap — just no friction anymore.
The CLI is the killer feature. I can spin up an experiment faster than I can open a Jira ticket to ask our data team to build one. That's the whole pitch.
Finally a tool that treats "ship it or kill it" as a first-class question. We stopped having 45-minute meetings about whether a lift was real. The verdict is on the dashboard.
