Not an AI assistant.
An AI consultancy firm.

Describe what to build. A team of specialized agents interviews you to pin down the problem, designs the system high- and low-level, decomposes it into tasks, writes the code in parallel, reviews it independently, runs the tests, and merges a working pull request — while you stay the CEO.

Inside the firm

Watch a request move through the multi-chain

Every build is a chain of independent model calls — each agent has its own prompt, its own model, and its own git branch. Work flows link to link until it's verified and merged.

Meet the firm

Five bots. Five jobs. One shipped product.

Each agent runs as its own process with its own model and system prompt — so the bot that reviews the code is genuinely independent from the bot that wrote it. Chen owns backend and infra; Bob owns frontend and GitHub — and what lands on main. Click any teammate to hear what they do.

Alex — Director

Turns your idea into a project and a plan. Sets direction, never writes code.

Jordan — Product Manager

Owns the PRD, design spec and acceptance criteria the build is graded against.

Chen — Backend & Infra

Owns the backend and infrastructure — APIs, data pipelines, databases, and cloud. Builds on parallel git branches; Bob reviews and merges.

Priya — QA / Reviewer

Adversarially audits every diff. Rejected work loops back with feedback in context.

Bob — Senior Engineer

Controls the frontend and GitHub — UI architecture, branches, every merge, conflict resolution, repo health, and firm memory. Owns main.

Under the hood

One firm. Every model. Any cloud.

A single routing layer dispatches each agent to the best model for its seat — and runs on the cloud you deploy to. Swap a model live; the rest of the firm never notices.

Why it's different

A single assistant guesses. A firm finishes.

CapabilitySingle AI assistantBuilderBots
Code reviewChecks its own workIndependent, cross-model reviewer
"Done" meansSelf-certified, often falseTests + lint + build + review pass
ConcurrencyOne thing at a timeParallel subtasks on real git branches
MemoryForgets between sessionsPersistent tasks, decisions & cost
Cost controlNoneHard caps + kill switch, per task/day
ModelsLocked to one vendor20+ models, swap per agent live

Verified, never "claimed"

A task only closes when the database proves tests, lint and build all passed. No false "all done."

Budgets & kill switch

Per-task, per-project and daily spend ceilings, checked at every phase. No 3 a.m. runaway loop.

Your work stays yours

Each project runs in an isolated workspace with tenant-locked data. You see your projects; no one else does.
