AI consulting for small businesses that ends in a working build.

Most AI consulting ends in a slide deck. Ours ends in a build for small and mid-size businesses. A free one-page plan says what to automate first, then we build it: a custom AI agent for your business, running offline when your data can't leave the building. We also publish our earlier agent platform and a trust standard for self-hosted AI, free to use.

Custom work by the team behind our three products, priced after a free one-page plan. A small business usually starts with the AI front desk · all three products

From service engagement to open code to offline deployment.

Each layer covers a different need. Most clients start with the consulting engagement that ends in a build. The open source platform and SHAITS standard are public: self-hosters welcome, no engagement required.

A call, then a free one-page plan, then a fixed-price first build: a custom AI agent in your Telegram, Slack, or website, OAuth-connected to the tools you already use.

SAE4U Agent

The multi-tenant AI agent platform we built as a SaaS product and published under Apache 2 when we stopped selling it in May 2026. Fork it and self-host it. The systems we build for clients today are made for each client, not run on this code.

SHAITS

Self-Hosted AI Trust Standard. Open specification for trustworthy self-hosted AI agents: data residency, audit logging, telemetry policy, encryption at rest, key rotation. Our own self-audit is next on the registry.

Air-gapped / on-prem AI

Local LLM inference (llama.cpp + Mistral or similar), local Whisper transcription, no cloud round-trips, for engagements where data sensitivity rules out external APIs. Custom-built per engagement.

The platform is open. The engineering is the value.

Most AI consulting firms keep their tools proprietary as a moat. We took the opposite stance. We publish our tools as open source and charge for the work of building a system around your business. You are not locked into our tooling.

When we build your agent, the code is written for your business and stays yours: you can audit it and run it elsewhere if our engagement ever ends. The trust comes from full visibility, not from contractual lock-in.
