How Cherto works
Your product
Experiments live in your code. Randomise with Cherto or your existing tooling.
Cherto
Rigorous assignment. Trusted statistics and intelligence.
Your warehouse
Any data becomes a metric. Computed in place, so raw data never leaves.
Raw data never leaves your warehouse. Only aggregates reach Cherto.
Everything the best teams expect
A/B testing. Ship what works. Draft, launch, conclude, roll out. Every change on record.
Feature flags. Release with control. A flag and an experiment are the same object.
Targeting. Reach the right users. Attributes, groups, app versions. Overrides for QA.
Warehouse metrics. Your data, your metrics. Define them once, computed where your data lives.
Advanced statistics. Decide with rigour. Frequentist and Bayesian. CUPED, sequential testing, delta method, winsorisation and more.
Trust checks. Trust the numbers. SRM, crossover, guardrails and more, on every run.
Holdouts. Measure the whole. Hold a slice out and see what everything was worth.
Built for AI. Agents welcome. Console API and MCP server. Agents run experiments alongside people.
Capabilities you've never seen
Built for the hardest, most pervasive problems in experimentation. We show them in person. From the growth and experimentation leaders who've seen them:
- “A new generation of the problem space.”
- “The most advanced platform I've seen.”
- “Not a single tool does this.”
- “I'm honestly blown away.”
Who Cherto is for
We think you'll love Cherto if
- You're building a high-traffic software product, and experiments decide what ships.
- You want server-side, warehouse-native experimentation done properly.
- You want to scale the program without scaling the team, and put your experts on the hard problems.
- You want to run experimentation the way the world's best product companies do.
- You want to work with a team who live and breathe experimentation and are building what comes next.
Probably not for you if
- You want to test landing pages with a visual editor.
- You don't have a data warehouse, or don't plan to.
- You're looking for a tool to run your first few tests. Come back when you're running your fiftieth.
- You want to sign up with a credit card and never talk to a human.
Why a new platform
Running A/B tests is easy. Running an experimentation program that shapes decisions across a business is not. That gap holds the hardest problems like delivering executive value, teams with competing goals, and knowing what's worth building next.
Other platforms leave those problems to you. Most were built for testing web pages, with the warehouse added later. The ones pushing the boundaries have been absorbed into much larger companies. And AI is only making these problems harder.
We've spent our careers closing that gap, building server-side, warehouse-native platforms at massive scale. Cherto is built from the ground up the same way: an opinionated platform that helps teams work differently, and makes experimentation part of how the business operates.
If that's the role you want experimentation to play, we'd love to talk.

Frequently asked questions
- What is Cherto?
- Cherto is a server-side, warehouse-native experimentation platform for product and engineering teams. It covers A/B testing, feature flags, targeting, warehouse metrics and holdouts.
- Does our data leave our warehouse?
- No. Metrics are computed in your warehouse, so raw data never leaves it. Only aggregates reach Cherto.
- Do we need a data warehouse?
- Yes. Cherto is warehouse-native, so metrics are defined and computed in your warehouse. If you don't have one, or don't plan to, Cherto probably isn't for you yet.
- Can AI agents run experiments in Cherto?
- Yes. Cherto has a console API and an MCP server, so agents run experiments alongside people.
- Who is behind Cherto?
- Cherto was founded by Simon Jackson, who led experimentation at Booking.com, Meta and Canva. He is joined by founding engineer Jacob Christophersen, who built and led engineering at Microsoft and Block, and founding statistical engineer Ashley Anderson, who built and ran experimentation at SEEK and Xero. Cherto is headquartered in Sydney, Australia, and backed by January Capital.
- Is Cherto available now?
- Yes, at an early stage, working with a handful of teams. Early partners work directly with the founding team. The fastest way in is to email the founder at simon@getcherto.com.
