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.
Company brain
Five tools, five answers, no single truth. 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.
Answer engine optimization
Buyers now ask ChatGPT, Perplexity, and Google AI who to trust. Do you show up — and is the answer right? We measure how answer engines describe you, fix the source material they cite, and track the drift monthly.
For
B2B companies, agencies, and SaaS teams where AI answers are becoming the buyer's shortlist.
Sovereign government copilot
When your data can't leave the country, cloud AI is off the table. Ours runs inside your network — trained on your country's public data, fine-tuned on your documents under NDA, drafting in your official voice within 48 hours.
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
Build it once, run it forever: weekly reports pulled from your tools, drafted in your voice, sent by Friday morning. For an agency with 10 clients, that's 60–80 hours back every month.
For
Ops managers, account managers, consultants.
AI phone agents
Your agent gets a real phone number. It answers, calls, and texts — and every call leaves a recording, a transcript, and an audit trail.
For
Agent builders, SaaS support teams, on-call engineering, local services, and personal assistant apps.
Multi-agent operations team
Two people. Five agents. The output of fifteen. We design the agent team, wire it into your tools, and hand you the controls.
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, we build exactly what your workflow needs — fixed scope, owned by you, maintained by us.
