Lumir Growth Partners Research
Investment Thesis
Lumir Growth Partners (formerly Lumir Ventures) is a growth-stage deep tech investor born in Israel. Its stated thesis is backing visionary founders tackling the hardest challenges in frontier industries, with four named focus areas: artificial intelligence, cybersecurity, quantum computing and frontier infrastructure. The firm says it partners with growth-stage founders born in the Israeli ecosystem who are reaching for global leadership. Its partnership philosophy is summarized as Trust, Excellence and Performance, and it describes itself as a close-knit team that works alongside founders rather than at arm's length.
Stage Focus
Lumir invests from the early growth stage to global leadership. Third-party profiles describe early to mid-growth Israeli technology companies, and the portfolio shows participation in Series A through Series D rounds (for example Quantum Art's $100M Series A, Scopio Labs' $50M round, Gloat's $90M Series D and the Weka mega round). It does not present itself as a pre-seed or seed fund.
Check Size
Lumir does not publish check sizes. The firm raised a roughly $140M first fund (Lumir Israel Tech Fund 1, launched March 2022) and now refers to a second vehicle (Lumir Growth Tech Fund 2 per third-party listings). Check size is therefore not stated and is left unset in the profile rather than guessed.
Lead Tendency
Public announcements use language such as "participates in", "backs" and "partners with", which points to a mix of lead and follow roles in large rounds. Lead tendency is recorded as unknown.
