Duku AI is now Antidote

About Antidote

Someone is on the other side of every click

We’re building the verification layer for software made by people and AI, so it works for everyone who depends on it.

Founded at

Antler, 2025

Based in

London

Founders

Ted and Will

Our story

Two careers. One conviction.

Will spent five years at Meta leading simulation-based testing, checking products the way the people using them would, before they shipped. Ted spent twenty years building commercial teams, most recently helping take Foodbomb from pre-seed to exit.

We met at Antler in London in 2025 sharing one conviction. Testing like Will’s used to take a company the size of Meta. Now AI writes code faster than anyone can check it, and every team needs it.

So we built Antidote. Antler backed us before anyone else in our cohort, and more than a hundred engineering teams told us what it had to do.

What we believe

What we hold ourselves to

We bring back the facts. You decide what to fix and when to ship.

Test the product, not the code.

When AI writes the code, checking the code is marking its own homework. We judge software by what it does for the person using it.

Show the evidence.

Every finding arrives with the recording and the steps behind it. You never have to take our word for it.

Never fake an all-clear.

If we couldn’t check something, we say so. A finished check is not a pass.

Faster engineers, not fewer.

We take on the checking, so your engineers get back to building.

The future
deserves to work

More room for possibility. More care for reality. Five commitments to the people who build software and everyone who depends on it.
