What's possible right now

Useful AI, not AI for the sake of AI.

Most businesses know AI changes things. Few know what to actually build. Here are nine systems we ship today — each one paid for itself before the year was over.

Company brain

Stop asking five tools the same question and getting five answers. We build one synthesized, cited model of your business — every agent and every employee asks once, gets the right answer.

For: companies where the CRM, Slack, Drive, and the senior PM each tell you something different.

Sovereign government copilot

AI you can actually deploy when your data can't leave the country. Pre-trained on publicly available Estonian content; fine-tuned on yours under NDA. Within 48 hours your team is drafting in their official voice — without a single byte leaving your network.

For: ministries and municipalities where legal blocks every cloud AI tool.

Document drafter in your voice

Senior-partner drafts in 90 seconds. Trained on your last 30 contracts and your house style. Cuts drafting time 70–90% — junior associates stop writing boilerplate, partners stop rewriting it.

For: law firms, consultancies, family offices.

Weekly autopilot reports

An agency sending 10 weekly reports saves 60–80 hours a month. Build it once, run it forever. Pulled from your tools, drafted in your voice, ready to send by Friday morning.

For: ops managers, account managers, consultants.

Custom outreach engine

200 personalized emails a day, each one referencing something real about the recipient. Templates are dead. This isn't.

For: outbound teams stuck choosing between volume and personalization.

Multi-agent operations team

Two people. Five agents. The output of fifteen. Built for teams that need enterprise output without enterprise hiring.

For: 1–10 person companies scaling without headcount.

Internal knowledge copilot

"Where did we say that?" — answered in 3 seconds, with the source link. Across your contracts, tickets, wiki, and Slack. Cuts internal search time 80%.

For: support, legal, finance, and HR teams that drown in "have we answered this before?".

Custom B2B software

Working software in 2–4 weeks, not 2–4 quarters. When SaaS doesn't fit and the agency quoted 6 months and $200K, we build the right tool for half the price, in a quarter of the time.

For: companies that have outgrown off-the-shelf.
