Mainprise

Mainprise

Mainprise functions as the family office for the principals behind CrowdStrike Holdings, the publicly traded endpoint security platform that defined a generation of cloud-native cybersecurity products. The firm was established to manage and preserve the wealth created by CrowdStrike's June 2019 initial public offering, which valued the company at roughly $11 billion, and its subsequent share-price appreciation as the business scaled past $3 billion in annual recurring revenue. The office's core mandate is diversification away from a highly concentrated single-stock position. The investment strategy is private-market-focused, with capital deployed across venture capital, growth equity, and select buyout funds. Mainprise participates both as a limited partner in external funds and through direct co-investment vehicles, targeting technology-adjacent sectors that fall outside the cybersecurity concentration of its founding wealth. Confirmed investment postures include allocations to enterprise software, fintech infrastructure, and digital health, per public record. The office evaluates opportunities primarily in North America but has reviewed select Western European and Israeli technology investments, reflecting the networks built during CrowdStrike's global expansion. Team size and specific deployment volume are not publicly disclosed. The office does not maintain a public-facing marketing presence, consistent with the operating preferences of many concentrated-wealth family offices that manage single-source technology fortunes. No dedicated philanthropic foundation has been formally linked to the Mainprise entity in public filings, though the CrowdStrike co-founders, including George Kurtz and Dmitri Alperovitch, have maintained individual charitable and policy-oriented activities through separate vehicles. Mainprise's structural differentiator is the depth of its cybersecurity domain expertise. The principals retain practitioner-level knowledge of a sector that institutional allocators often struggle to underwrite, which informs their ability to diligence adjacent infrastructure software, cloud, and threat-intelligence deals with a technical lens most generalist family offices cannot replicate. This operating-company heritage creates a sourcing advantage in the overlapping zones between security, developer tools, and enterprise infrastructure.
