The AI engineering platform for your whole team

Your team is running more work than anyone can keep in their head. Foundry keeps track of all of it, and makes sure everything you ship is built the same way.

Foundry keeps the science consistent, so your team can focus on the art

Foundry keeps the science the same everywhere: every change follows the same steps and the same patterns. Your team decides and approves, and puts its craft into the product.

Plan

You describe the work, and Foundry breaks it into stories.

Build

Agents build each story in parallel.

Check

Your tests run again, and a second model reviews the work.

Approve

You approve the change before it ships.

Foundry checks the work itself

Foundry reruns your tests and checks and records the results. An agent can't mark its own work as done.

A second model reviews every change

One model builds, and a different one reviews the work against your docs. Findings are fixed before a person looks.

Every service reads like one team wrote it

Errors, logging, permissions, and data access work the same way everywhere, so people and agents get it right the first time.

Two services, written the same way
billing/get-invoice.ts
const invoice = await repo.get(id)
if (!invoice) throw new NotFound(id)assertCan(ctx, 'invoice.read')log.info('invoice.read', { id })
return invoice
orders/get-order.ts
const order = await repo.get(id)
if (!order) throw new NotFound(id)assertCan(ctx, 'order.read')log.info('order.read', { id })
return order
Both use the same error type, permission check, and log line.

Agents read your patterns before they write

Foundry builds a Knowledge Center from your code and keeps it matched to the code as it changes.

Your architecture, patterns, and decisions, each with an owner.

A Knowledge Center doc describing the platform architecture

How every doc connects across your services.

The Knowledge Center graph linking docs across services

Every doc is checked like code before agents can use it.

Quality checks passing across the Knowledge Center

When the code changes, Foundry drafts the doc updates for your team to review.

Docs flagged as out of date, with drafted fixes

Start new products on a full platform

The Full-Stack Foundation is an optional add-on. Agents build a complete, working platform into your repo, documented end to end.

4 yearsin production across multiple platforms

Foundry also works on the code you already have.

We use Foundry to build our own software

After its first release, Foundry built the rest of Foundry. Our engineers use it every day to build software for clients.
