Montamo

What Montamo does

Montamo GmbH is a Berlin-based, vertically integrated heat pump installation company founded in 2023 by Alexander Böhm and Ole Schaumberg to address Germany's skilled trades shortage in the green energy transition. It delivers full-stack residential heat pump installations — covering dismantling of legacy heating systems, foundation and electrical work, installation, and commissioning — using only directly employed, in-house teams rather than subcontractors. The company complements installation with photovoltaic and wallbox add-ons, post-installation maintenance packages, and a dedicated multi-family building (WEG) offering that includes BEG subsidy application support up to €30,000 per residential unit. Its proprietary assets include the Montamo Akademie (an internal training academy that has upskilled previously unemployed and migrant-background workers into HVAC specialists), the Lubo Field mobile application, and self-developed digital planning and project-coordination tools that standardise the consultation-to-commissioning workflow.

Montamo operates three parallel go-to-market motions: direct-to-consumer sales to residential homeowners via website and on-site consultation, a B2B Handwerkspartner (subcontracting) channel for heat pump and solar sellers that need installation capacity, and an SHK franchise network that gives qualified heating and plumbing masters access to Montamo's project pipeline, training, and digital systems. Pricing is fixed-price per project with no surcharges, revenue is predominantly one-time installation fees with a recurring maintenance stream, and franchise fees add a managed-services revenue layer. The company has scaled from founding to four German offices (Berlin, Stuttgart, Munich, Erftstadt/Cologne), 65–100 employees, 225+ heat pumps installed, and roughly €9M of total disclosed financing across a 2023 Project A Ventures-led seed and a 2025 Alter Equity 3P-led Series A. All current operations are domestic to Germany, with trade-fair activity at The smarter E Europe 2026 signalling potential future European expansion.
