European energy service provider ista SE has acquired Homenergy, a Munich-based provider of residential energy solutions, for an undisclosed sum. The deal was announced in October 2026, with Berlin advisory firm Apricum acting as exclusive sell-side financial adviser to Homenergy.
Founded in 2022, Homenergy sells heat pumps, photovoltaic systems, battery storage, EV wall boxes, and air conditioning, pairing its platform with in-house installation.
Homenergy's founder and CEO Hannes Münzinger and its team now operate under ista SE, one of Europe's leading energy service providers. The acquisition gives Homenergy access to ista's resources to accelerate growth and expand its residential electrification offering in Germany.
Apricum, the sell-side adviser, also benefits from the deal's visibility in the climate-energy M&A space.
Established energy incumbents are buying into home electrification as demand for heat pumps, solar, and battery storage climbs. Acquiring a four-year-old startup gives ista a ready-made platform to reach German homeowners directly.
Watch for ista's next moves: whether it integrates Homenergy's platform across its broader service portfolio or uses the acquisition as a template for further buys in the residential electrification space. The deal's undisclosed value leaves room for speculation on future deal multiples.
Also monitor Homenergy's growth trajectory under ista—if it expands beyond Germany, it will open new sales opportunities for adjacent software and service providers.
