About
We have been friends for more than five years. Henry studied mechanical engineering and works in software and hardware, building and flying drones for inspection. Paulo studied computer science and works in cybersecurity. Both of us grew up around old estates.
Keystone started while we were traveling together, visiting castles and estates across Europe. We kept meeting owners who did not have a good view of their building's condition — so we began helping out by checking with a drone and making a report. Today, we still fly the surveys ourselves, still keep the data secure, and still work directly with every client.

Background in mechanical engineering, Henry has spent his career working with software and hardware — most recently building and flying drones for inspection work. He grew up around old estates, loves being outdoors, and is usually the one figuring out how to reach the part of the roof nobody else can see.
Co-founder · Tech
Trained in computer science, Paulo works in cybersecurity and builds the software that keep Keystone's data safe, organised and easy to access. He grew up around historic buildings and is the reason your reports, models and records stay private and well-structured.
