Hi, I'm Kurt.

I build things
that run without me.

AI agents that trade, a protocol that clears payments, DeFi nodes that never sleep, critical minerals, and coffee from places most never visit. All running.

About

Built to build.

I run several companies at once and most of the work is the same job in different clothes: find the bottleneck, build the machine that removes it, then get out of its way. A trading model, a settlement solver, a roasting profile. What drives me is the challenge — being a beginner again, learning something new, getting better every day, and doing it with people from all over the world.

I write the code myself, mostly Rust and Python, and I also know what a green coffee contract looks like in Colombia. That lets me move between founders, developers, traders and farmers without losing the plot.

Where I come in

What I do.

01

AI & financial intelligence

Turn market noise into decisions.
NORTH7: AI agent infrastructure for finance. A team of specialised agents researches markets, forecasts commodities by analysing news, geopolitics and supply chains, aggregates portfolios across banks and answers through an API. Built for people who trade their own money.
02

DeFi infrastructure

Run the plumbing nobody sees.
CoW Protocol solver, Lava Network RPC provider, UniswapX filler, keeper and arbitrage bots. Nodes, staking, uptime, recovery. Solo-operated since 2002.
03

Trading systems

Let the machine take the trade.
Algorithmic trading under NORTH7 Paradox Software LTD. Bots and AI agents handle signal research, execution and risk management. The goal: regulated ETFs and investment funds powered by the same infrastructure.
04

Specialty coffee

Coffee for the Soul — from origin to cup.
Coffee for the Soul GmbH. Organic, direct-trade specialty coffee. One roastery, direct relationships with growers on several continents, and the barista textbook now in its eighth edition.
biokaffeeroesterei.at →
05

Payments

Give AI agents a liability answer before they spend.
Fivefield: an open protocol that checks every agent transaction against a signed mandate before the money moves. One field on any rail — Visa, Mastercard, SEPA, Wero, stablecoins.
06

Raw materials

Critical minerals and specialty commodities.
Gallium, tantalum, tungsten and other critical raw materials. Import and trading through Traxl Gruppe — direct sourcing from producers, building supply chains in regions where most traders never go.

Fivefield

The liability layer for payments made by AI agents.

The cardholder signs five fields once in their banking app. Every order the agent places is checked against those fields before the money moves. Inside the scope, the customer pays as if they had clicked. Outside, nothing is charged, and if it is, the agent provider is liable.

An open protocol that fits into one field of any payment rail, from Visa and Mastercard to SEPA, Wero and stablecoins. Fivefield operates the verifier.

Selected work

Selected work.

A few things I've built, run and kept running.

CoW Protocol

Solver "paradox".

A settlement solver competing in CoW Protocol's batch auctions. Finds routes, prices surplus, submits solutions, and loses money fast when the config is wrong. Written in Rust.

3chains: Arbitrum, Ink, Solana
24/7auction participation
Lava Network

RPC-Provider "paradox-arb".

Staked RPC provider serving chain data to Lava's network. Endpoint operations, staking, outage recovery and chain expansion, run from my own servers.

  • Node Ops
  • Staking
  • Multi-chain
  • Monitoring
Coffee for the Soul

Premium specialty coffee, roasted at night.

A premium roastery with direct-trade sourcing, alongside the organic line Biokaffeerösterei Traxl. Green coffee selection, roasting, positioning and the systems behind the shop.

8editions, Barista Know-How

Traxl Trading

Algorithmic trading and import.

Co-founded trading company: a quantitative trading operation in validation, plus the import side that brings green coffee and cocoa into Europe.

Projects

Lab.

Experiments and side builds. Some useful, some weird, all mine.

Fivefield

Prototype
The liability layer for payments made by AI agents.

Five signed fields, one verifier, any rail. 107 tests, public verifier, live demo. Pilot partners wanted.

Tokenized fund ops

Validating
Exception handling for redemptions that don't reconcile.

90-day validation: 10 to 15 conversations with people who run tokenized funds. Three matching problems and we build a paid pilot.

morpho-guard

Building
Deleverage protection for Morpho Blue borrowers.

A keeper that watches your position and unwinds it before the liquidator does. Base first.

Telligence

R&D
OSINT early warning with probabilistic forecasting.

Open-source signals in, calibrated probabilities out. NORTH7 research project.

Thinking

Notes from the engine room.

LinkedIn · Nov 2026
Everyone is talking about tokenization. I spent the last few weeks figuring out where the money actually is. The answer is unspectacular.

The money isn't in issuing tokens. It's in running them afterwards. An investor redeems tokenized fund units and wants their cash: order, fund accounting, register, blockchain and payments all have to agree. When they don't, a human spends hours finding out why.

The evidence. DTCC launched its Tokenization Service on October 28 with 20 firms signed on, from JPMorgan to Citadel Securities to Fidelity. Securitize crossed $5B in tokenized assets and more than tripled its net loss year over year. Tokenization revenue down 12%. Fund administration revenue up.

The thesis. Software that finds exactly these cases, classifies them and routes them to whoever has to act. Not a dashboard with three numbers side by side. A line that says "payment confirmation missing, deadline passed, payments team is up."

What I don't know. Whether enough fund administrators have this problem, whether they'll pay, and whether the platforms just build it themselves. UBS ran a live on-chain redemption with Chainlink a year ago. The happy path is solved. My question is what happens when it doesn't apply.

The plan. No pitch. 90 days, 10 to 15 conversations with people who operate tokenized funds today. Show me your last unresolved redemption case. If three firms describe the same problem, we build a paid pilot. If not, that was a cheap lesson.

Solvers are the exchanges now.

Why batch auctions quietly moved the price-discovery job from order books to whoever writes the best solver.

An agent needs a mandate, not a wallet.

Giving AI agents money is easy. Giving them five signed fields and a liability answer is the actual product. The thinking behind Fivefield.

What roasting taught me about trading.

Both are feedback loops with a lag. Overreact to the last reading and you burn the batch.

Got something worth building?
Let's talk.

I'm always looking for exciting projects with cool people around the world. A protocol that needs a solver, a market that needs a model, a product that needs someone who ships. Send it over.
