What we’ve built — and what each one made possible.
XXI is the software studio for creators. A selection of what we’ve shipped — consumer apps, agents running in production, and the infrastructure underneath. Hand-coded, source-owned, no templates.
Each acts inside hard bounds — read-only by default, your approval on anything consequential, every action logged. Built to run, not to demo.

Operator
Your company’s own AI, wired to the apps you already use. It does the work you describe in plain English and stops for your approval before anything consequential.
Recovers revenue from dead leads — scores each one, drafts the next message in your voice, classifies the reply, and books the call. A human approves every send.
An inbound voice agent that answers, qualifies, and books — built for trades, clinics, and local service businesses. Every call transcribed and logged.
For creators — reads every comment and DM, catches buyer-intent even off-keyword, replies in your voice, and converts. Two layers: comments for reach, DMs for the close. Instagram + TikTok, official APIs.

SetupScore
Snap your desk setup, an AI scores and roasts it, then points you at the upgrades. Built on a vision model — Cal-AI’s mechanic pointed at battlestations.
The SaaS that sells absolutely nothing. A deadpan-premium fake startup — a live leaderboard, a counter, and a shareable Certificate of Nothing. An attention machine, on purpose.
The engineering the rest of the work inherits — built to a depth most shops never touch, and pressure-tested on our own operation first.
Memory layer
One memory every agent inherits.
A multi-tenant memory layer every agent on our stack reads and writes against — hybrid semantic and lexical retrieval, per-tenant isolation, and append-only provenance on every write. Recall returns a ranked, audit-traceable answer.

Append-only provenance on every write
Governed runtime
Bounded authority, proven.
A runtime that hands bounded authority to an AI: every consequential action passes a safety gate, lands as a signed receipt, and can be revoked mid-run. The full loop emits a run a skeptic can reproduce.
