montamo raises €6M to boost Germany’s green energy push; aims to train and hire 1,000+ people in 5 years

Berlin-based montamo, the next-generation heat pump installer for manufacturers and vendors, has secured €6M equity in a Seed funding round.

The funding round was led by Alter Equity through its third fund, Alter Equity3PIII, with participation from the U.S. fund Rethink Education and existing investors, such as German fun Project A Ventures and British fund Firstminute Capital.

As the first European impact investment management company, Alter Equity focuses on investments that benefit people and the environment alongside profitability.

The firm currently manages over €235M through three funds: alter equity3P, alter equity3PII, and alter equity3PIII.

Fanny Picard, Chairman of Alter Equity, explains: “montamo addresses a crucial challenge: enabling the installation of equipment that drives the energy transition for households. This investment aligns perfectly with the strategy of our third fund, which supports high-growth startups whose activities and business practices contribute to the long-term well-being of people and the environment. montamo strengthens the environmental impact of our portfolio, which has already prevented 8.9 million tons of CO₂eq emissions as of end of 2024—equivalent to more than 2% of France’s total emissions.”

This funding round will enable the company to expand its geographic reach in Germany.

The company is using this funding round to expand its integrated model and become the top installer of energy transition assets in Germany.

After starting operations in Munich, the company plans to open more hubs in major cities, with a second hub recently launched in Stuttgart.

montamo: Next-generation heat pump installer 

Founded in 2023 by Alexander Böhm and Ole Schaumberg, montamo specialises in the fast and reliable installation of energy transition equipment.

Focusing on heat pumps, montamo supports manufacturers and distributors by offering a turnkey service.

The German company has started a training academy to help people changing careers, especially those from disadvantaged backgrounds, find stable jobs in a growing field.

“The labour shortage is not just a challenge for heat pump installations— it is a global issue for the energy transition. We provide a second career chance to individuals from other industries that have often been overlooked in the German job market before by offering them stable long-term career in a fast-growing sector. We are not just installing heat pumps; we are building the teams that will enable the energy transition,” says Ole Schaumberg, Co-founder of Montamo.

Since its launch, montamo has trained and hired over 30 installers in Munich, with a strong commitment to providing its installers with real career prospects.

Just 12 months after launching operations, the company has installed for a wide range of clients, including multiple heat pump manufacturers, energy consultants, D2C players and utility providers.

“Our mission is to boost the installation of energy transition assets for households in Germany by providing manufacturers and distributors with a turnkey service that ensures price visibility, availability, and service quality. With this funding, we will expand our presence beyond Munich and Stuttgart and establish hubs in several major cities to significantly increase our installation capacity and geographic coverage,“ says Alexander Böhm, Co-founder of montamo.
