IBB Ventures has joined a group of business angels and industry specialists to back Nanolope with €800,000 in pre-seed funding.
The round was led through IBB's B# fund, a €10m EU-backed vehicle targeting early-stage deep-tech teams in Berlin with tickets between €100,000 and €400,000.
Nanolope, founded in 2025 by Dr. Felix Marske, Eric Matthes, and Dominik L. Schreiber, makes panel-based thermal storage systems that can be retrofitted into walls, ceilings, and floors of existing residential and commercial buildings – hotels, offices, and apartment blocks among them. The panels use phase-change materials developed under green chemistry principles, without rare earths, and are claimed to be largely recyclable.
The company says its technology can reduce heating and cooling loads, stabilise indoor temperatures year-round, and cut CO2 emissions – without requiring a full building renovation. The target market is housing companies and commercial property operators looking for lower-cost, lower-disruption efficiency upgrades.
Sabine Wolff, principal at IBB Ventures, said the team had convinced her with "their expertise, experience and ambitions to set new standards in the construction industry with their patented energy storage materials."
"The heating transition will be decided in existing buildings," said Marske. "Many properties need solutions that can be retrofitted quickly, economically, and without major structural work."
Nanolope plans to use the capital to scale production, run first pilot projects, and grow its team.
