I build AI agents that save you time.

Tell me the job that eats your week. I build an AI agent that does it or speeds it up, with a person still saying yes before anything goes out. Then we measure the time saved, before and after.

// WHAT I'VE BUILT FOR MYSELF FIRST

A company run on AI agents

Acorn Labs runs on a team of AI department agents in one workspace: a manager agent hands out bounded jobs, departments research, draft and check, and nothing is sent, spent or published without my yes. Every decision and mistake goes into one written record.

Training and exams for AI agents

Each department gets a study pack for its real job and a scenario exam. A separate model marks the answers, flags anything copied from the model answers, and the results are kept. A trainer writes the next course from each department's weak spots.

Search that rates its own sources

A research tool that splits an answer into claims, re-opens every source to check the quote is really there, and rates each source: official, news, reference or weak, with the page date. A correct quote from a weak or AI-farm page is marked as weak.

Numbers that can say "I don't know"

A usage dashboard for the agent team that shows when a figure can't be read, instead of making one up. It took four passes to get there, and the write-up says why.

Holdfast (free)

One shared memory and rulebook for Claude, Grok, ChatGPT and coding agents: a Python MCP server with a web dashboard, setup guide and undo history. Two testers. It's free. See Holdfast →

A marketing memory (growth-os)

The system behind the marketing: what buyers say in their own words with the source, content made from it, warm follow-ups, tests, pages built to be cited by AI assistants, and a weekly one-page cockpit. How it works →

// CASE STUDIES

Real jobs, measured

These are being built now. Each one gets a before-and-after number, including if the number doesn't move.

In progress

Content-ops agents for a marketing team

A real marketer's week: sorting photos and videos sent in from jobs, turning them into branded reels, writing the social posts, proofreading writers' content and refreshing old blog and service pages for search. One agent at a time, starting with whichever eats the most hours. The company's material stays on their side.

Your job here

I'm building a few agents free in return for writing them up. Quote follow-ups, admin, reports, proofreading, social posts: if it eats your week, it's a candidate.

Planned

Lead follow-up for a B2B business

An automation that notices when a lead goes quiet and prepares the follow-up for a person to send. Built in n8n. Named here only if the business agrees.

What eats your week?

I'm building a few AI agents for free, for real businesses, so I can write them up as case studies: time before, time after. No names or private details unless you agree. Tell me the job, roughly how long it takes now, and what you're happy for me to see. Or describe the one job here.
