Creating paths for AI to do work that lands and holds.

Efficacious makes what an AI agent needs to deliver, not just answer: a place to build, a place the work persists, and a standard it's held to.

What we make

Live now

Apphaven

Where the apps an AI agent builds live. A person describes what they need to the agent they already use; Apphaven gives the result a home, with sign-in, a database, email and a console, and the agent keeps looking after it.

How we work

Rigor above.: An agent is only as good as what it can count on. We build the parts that have to be right every time: hosting, identity, data, billing, mail.
Capability within.: Everything we ship is made to be driven by an agent and run by a person, with no engineer between them.
Plain words.: If a thing can't be explained to the person paying for it, it isn't finished.

Get in touch

Partnerships, press, or a problem you think an agent should be solving. We read everything and reply ourselves.
