The agency
One industry. One connected system.
Stroom Digital builds websites and growth systems for installers of heat pumps, solar panels, insulation and airco in the Netherlands. Nothing else.
01Why installers
The energy transition runs on installers.
Homeowners want a lower energy bill and a more comfortable home. They search, compare and request quotes, often in the evening.
The installer who responds first and plans the survey is the one they remember. But installers are on site when those requests come in.
So we build one thing, and build it well: a system that answers every request straight away, qualifies it and puts the survey in your calendar.

02Founder
Andrea Galli
Founder
Before Stroom Digital, Andrea ran an agency in Italy that built this same system for local businesses that depend on booked appointments: the website, the ads, and the fast follow-up that turns an online request into a planned visit.
Installers are the clearest case of that problem. Every survey can lead to a job worth thousands, the owner is on site all day, and a request that isn’t answered quickly goes to a competitor. When it comes in, they’re on a roof or in a crawl space.
So Stroom Digital does one thing for one industry: it makes sure every homeowner who asks for a quote gets a fast answer and a planned survey.
“Your work is good. The problem is usually what happens between the request and the survey.”
