Company Overview
About 1KOMMA5°
1KOMMA5° is a Hamburg-based integrated clean energy company that sells, installs, and manages residential and commercial solar panels, battery storage systems, heat pumps, and EV charging equipment across Germany and six other European markets. Founded in 2021 by Philipp Schröder, Jannik Schall, and co-founders, the company operates approximately 80 locations and serves over 120,000 customers. Its proprietary energy management software, Heartbeat AI, continuously optimizes energy flows across a customer''s solar array, battery, heat pump, and EV charger — buying cheap grid electricity when spot prices are low and selling stored energy back when prices spike through dynamic tariffs.
Business Model & Competitive Advantage
1KOMMA5° achieved €520M in total revenue for 2024, of which €490M was organic (36% organic growth year-over-year), with the remainder from acquisitions. The company became a unicorn in 2023 with a €430M funding round, and extended a €150M pre-IPO round in July 2025 to bring in new strategic investors including Sabanci Climate Ventures. Total capital raised exceeds €600M. For 2025, the company plans to invest €100M in expanding its Heartbeat AI software business toward becoming a large-scale virtual power plant (VPP) operator that aggregates distributed residential assets.
Competitive Landscape 2025–2026
1KOMMA5° competes with installers and energy retailers but differentiates through vertical integration: it sells the hardware, does the installation, provides the financing, and continuously manages the energy system via software. The Heartbeat AI platform''s ability to enable households to participate in energy markets — earning revenue from flexible demand response — transforms customers from passive energy consumers into active grid participants. The company has approximately 2,500 employees across seven European markets.
