About

I’m Raúl Amedey - a software engineer, entrepreneur, and investor, based in the Netherlands. I build software businesses and write about AI, product strategy and lessons from operating real products.

Background

I’ve been writing software professionally for about twenty years, across enough different problems and stacks that I’ve stopped believing in universal best practices and started believing in “it depends, and here’s why.” What I find more interesting than any specific technology is the discipline of shipping and operating something real over a long period - the decisions look different once you’re the person on call for them.

Rentslam

For close to ten years I’ve been CTO and co-founder of Rentslam, a rental-alert service that scans listings across a large number of rental sites, deduplicates and enriches the data, matches it against what users are actually searching for, and notifies them within minutes. Speed and data quality are the entire value proposition: a rental listing can be gone within minutes of being posted, so a slow or noisy matching pipeline is a broken product. Operating something with those constraints for a decade has been the single biggest shaper of how I think about engineering tradeoffs, on-call reality, and what “done” means for a piece of infrastructure. More on that on the Rentslam project page.

What I work on and think about

I’m interested in AI as it applies to real product and engineering work, specifically the question of how agentic tools change what teams should spend their attention on. I write about product strategy, particularly the kind grounded in operating a real marketplace rather than theorized in the abstract. I follow real estate technology and marketplace dynamics closely, partly because it’s the space I’ve operated in and partly because marketplaces are an unusually clarifying test of whether a product actually solves the problem it claims to. And I invest, selectively, in software businesses where I think I can add something beyond capital.

How I work

I default to skepticism about anything that sounds good but hasn’t been tested against reality - including my own ideas. I’d rather ship something small that works and learn from it than plan something large and elegant that never meets a user. And I try to write about this stuff the way I’d want to read it: specific, and honest about what I don’t know.
