I build systems so businesses always answer the phone.

Founder & CEO of Enhanced Rentals — AI telephony for anyone who runs on the phone: calls answered, handled, and escalated around the clock. Proven first across the 500 rental units I operate at RENTUJEMY. Physicist by training, operator by trade, mountaineer on the off-days.

What I'm building now

Building the answer I needed as a property manager.

Enhanced Rentals is the product; RENTUJEMY is the 500-unit operation it grew up inside. Every feature met real guests before it ever met a customer.

The venture — what I'm scaling

Enhanced Rentals

Your customers always get an answer.

AI telephony that answers, handles, and escalates calls 24/7 — starting where I know the pain firsthand: short-term-rental operators and property managers, expanding to any business that lives on the phone.

The proof — where it was forged

RENTUJEMY

~500 units · Poland & Dubai.

A tech-driven European rental operation — and the proving ground the product was built inside. Every feature survived contact with 500 real guests before anyone else saw it.

Background

Physicist by training, software engineer by trade.

Physics taught me to model systems that don't want to be modelled. Software let me build them. Operating 500 units showed me which problems actually cost money — and AI turned out to be the sharpest tool I've had for the one that kept me up: nobody answers the phone.

Heidelberg

Physics

Learned to model systems that don't want to be modelled. Still how I think.

A decade

Engineering & founding

Shipped across InsurTech, mobility, blockchain, SaaS. Hands on the keyboard, not just the strategy.

Enhanced Rentals — founder

Turning the operator's answer to "who's picking up?" into a product for everyone who runs on the phone.

Off the clock

The systems buy the time — I spend it high up.

20+ summits across four continents, highest at 6,961m on Aconcagua, an Ironman 70.3 on minimal training, and jiu-jitsu most weeks. Not a hobby footnote — it's the same discipline that builds companies: decide fast, commit, keep moving when it's uncomfortable.

A short series on the calls that matter, drawn from altitude where hesitation has a cost. New entries as I climb.

Let's work together

If your business runs on the phone, we should talk.

Building Enhanced Rentals, operating RENTUJEMY, and open to the right conversations — customers, operators, and investors who get why "always answer" is a category, not a feature.
