Innventure builds companies around technologies developed by multinational corporations. It identifies unmet market needs using its partners' market intelligence, then screens each technology for at least six months in a diligence process it calls DownSelect. The companies it forms are run by executives who have led early-stage businesses.

Innventure holds interests in its operating companies on behalf of shareholders and manages them through capital allocation, governance and strategic initiatives. Those companies work on chemical recycling, liquid packaging and data center cooling. The approach differs from a portfolio venture fund, which spreads risk across many investments and expects most of them to fail.
