Joakim Riedel · Software developer, founder and speaker

I explore new technology, build with it and teach what I learn.

I have been building software since 1997, and I still get excited when a new technology changes what one person can make. I like to get in early, take it apart until I understand it, build something real with it, and then show others how.

Selected work

Propstreet

2017–2026 · Co-founder & CTO
From property matching to an agent-based product

I co-founded Propstreet and built its commercial real estate platform, matching brokers' deals with investors' acquisition strategies. I designed its matching engine, added language models so investors can describe what they want in their own words and language, and built an agent that works inside the application. Customer feedback shaped a workspace where people can watch it work and carry on themselves.

Operational CTO through August 2026; continuing board member.

Boreda

2007–2012 · Co-founder & CEO
Building the product and the business

The valuation system I designed and helped build at Boreda is still in use today, now as part of MSCI. We sold it to banks and real estate professionals, from brokers to property companies, and I ran the company as CEO until Värderingsdata acquired it in 2012.

Loggad

2026– · Founder
Keeping an object's history useful

I am developing a digital service journal for homes, vehicles and machinery. The aim is to keep an object's history, documents and practical knowledge useful through maintenance and changes of ownership. Every line of its code is written by autonomous agents; I build the factory they work in.

AGI IS HERE

2026 · Creator
An adventure that changes while you play

Describe an adventure, then play it as an agent builds the rooms around you. An open-source recreation of Sierra's AGI engine, with real game files you can inspect, save and remix.

Monotio

2017– · Founder
Product development, talks and workshops

Monotio is my consultancy, through which I develop products and work with other teams. My talks and workshops combine demonstrations, discussion and practical experiments drawn from what I am building and learning.

Technical
depth

From an idea to software people can use.

I am responsible for the whole chain: what the product should do, how it is built, how it is tested and how it behaves in production. With AI, that includes knowing what a model can do and building the software around it that makes it useful and safe.

Connecting models to the product
Tools that give a model the application's data and actions, limited to what the signed-in person is allowed to do.
Testing what the model says
Every real failure becomes a test. Code checks what code can know; a second model judges the rest, and a person reads what fails.
Keeping people in control
People can watch the agent work, undo its changes and approve anything that cannot be undone.
Running it
Traces, usage accounting and spending limits, so I can find out why something failed and what it cost.
