Built by installers
HappIT's founders ran a company that sold and installed solar panels. They know the complicated quotes, the error-prone files and the planning that never adds up. What started as software for their own business grew into a platform for the whole sector.
Today we work from Thor Park in Genk, Belgium, with a small team that knows the software and the sector equally well.
