Work with us · Open engagements

Three ways in.
One team.

Pietarien runs four engines — Nexus AI, Pieta, Metsi, and Labs. Every project on our subdomains came from these engines running on our own problems. We're now running them on other people's problems too. Pick the door that fits yours.

Track 01

You have a technical problem worth patenting. We'll find what's actually novel.

The Pieta engine runs a structured disagreement protocol against 791 real patents and actual physics. What survives is structurally novel. We run the engine on your domain, not ours — your knowledge, our pipeline.

5-week Idea Run — full Pieta pipeline on your technical domain: forge, rater, IP router, SYNTH compression, patent branch
Attorney-ready output — claims, drawings, prior-art search, commercial development kit per surviving idea
IPS gate enforced — only Diamond and Gold ideas leave the pipeline; you see why the rest were killed
Full IP ownership to you — we run the engine, you own the output

What the engine has done
791 real EPO patents in the grounding corpus
67+ attorney-ready packages generated
$173 total API cost to reach 67 packages
IPS 82 top Diamond gate — Adaptive Nunome cooling

Track 02

Your business runs on repetitive decisions. We'll build the AI that makes them for you.

Nexus is 300+ autonomous agents, a constitutional governance layer, and 18 months of tested memory architecture. We scope it to your operational reality — not a chatbot bolted onto your existing workflow, an intelligence layer that becomes part of your business spine.

Business Genome mapping — we document your 21 service families and 105 roles before writing a line of code
Custom agent deployment — SDR, bookkeeper, recruiter, customer support, or any role your business depends on
Runs on your hardware — fully local or hybrid; no data leaves your environment without your config
Constitutional guardrails included — OPA constitution, BSL-4 Scout gate, Chaos Scheduling stress-tested before handoff

Track 03

You have a real problem and not enough technical firepower to attack it properly.

This track is for early-stage founders and innovators who need the engines, not just advice. We're not an accelerator or a mentorship programme. We're offering to actually build with you — use Pieta on your IP, Nexus on your operations, or both.

Problem clarity first — a 2-hour session to turn your idea into a structured technical brief before anything is built
Engine access — one Pieta run on your domain or a Nexus scope-and-prototype on your core workflow
What we ask for — domain expertise, a real problem worth solving, and commitment to the process. Not money.
Equity or revenue-share considered — for the right fit, we'll structure it so you pay when you earn

What we've built for ourselves
10 SA business verticals on one spine — Pietarien One
141 tests passing on TeachOS — from zero to 4 phases
25+ peer-reviewed papers from the research pipeline
R1.5M Phase 1 budget — Bare Cruiser motorcycle project

How every engagement starts

01
You send a brief
One email. Tell us the problem, the domain, and which track you think fits. Don't over-polish it — a rough problem statement is fine.
02
We read it and respond in 48 hours
We'll either say which engine fits your problem and propose a scope, or explain why we're the wrong fit and point you somewhere better. No sales call required to get a real answer.
03
Scope and kickoff
If there's a fit: a 60-minute scope session to agree on the exact deliverables, timeline, and what you owe us (if anything). Then we start.
04
You see the engine run, not just the output
Every engagement includes visibility into the pipeline — you'll see the ideas the engine killed and why. The process is part of the value, not just the final deliverable.

Ready to work together?

Send a brief email — the problem, the domain, and which track resonates. We'll take it from there.
