We build software that acts on your behalf, and still answers to you.

The product studio of Utopian Ventures. A small team, a few products at a time, each built on the same conviction: in the agent era, the person the software works for holds the keys.
BRINGING AGENTIC AI TO EVERYONE
Feke
01 · EMAIL · PRIVATE BETA · GMAIL

The chief of staff your inbox never had.

Feke reads, files and follows up on your email, opens a case for anything that takes work, and drafts replies in your voice. Anything that leaves your account waits for your signature. Only the decisions reach you.

Caret
02 · KEYBOARD · IN DAILY USE, NOT YET RELEASED

Agents anywhere you type.

An iOS keyboard and Mac menu-bar app. Dictate, Ask or Imagine at any cursor, with your own agent on the other end over the open caret/v4 protocol. Caret inserts text. It never presses Send.

Zen
03 · BROWSER · BUILT, NOT YET IN STORES

Only the stone remains.

A Chrome and Safari extension that removes ads, consent dialogs, nags and modals, judged one element at a time by a model and remembered per site. Every removal is listed; one click restores it. Cookie banners get Reject, never Accept.

Your web. Your rules.

Describe the change you want on any website. The model you choose reads the page, writes a userscript, tests it in front of you and saves it. Any LLM, including local ones. No account, no tracking.

KLAW · THE PROOF SYSTEM · NOT A PRODUCT

Utopian Labs productizes what Klaw proves.

Klaw is the internal agent that runs the founder's real inbox, codebase, travel and firm every day. Capabilities that hold up in daily use become products. Feke, Caret and the Minions coding harness all started here.

1,800+ VERIFIED CODING MISSIONS
The Minions mission-control dashboard with demo data: a fleet summary, a running coding mission, a question waiting for an answer, and recent outcomes
HOUSE RULES
Approval before consequence.
Constraints live in software. A rule that lives in the prompt is a rule the agent can lose.
Delegated work comes back with evidence that it ran, passed, and stayed in bounds.
