## March Capital Partners and his role
March Capital is a venture capital and growth equity firm headquartered in Santa Monica, California, investing globally since 2014.[3](https://stubbsalderton.com/join-us-for-the-next-investor-360-roundtable-interview-with-jed-leidheiser-of-march-capital/) Its inaugural fund was $240 million.[2](https://labusinessjournal.com/finance/march-capital-partners-closes-300m-fund-ii-adds-tw/) When the firm closed a $300 million Fund II, it named two new partners: Meredith Finn, previously of Salesforce Ventures, and Leidheiser, promoted from vice president.[2](https://labusinessjournal.com/finance/march-capital-partners-closes-300m-fund-ii-adds-tw/)
The firm's stated approach, as reported by the Los Angeles Business Journal, targets 20 to 25 percent ownership when investing early; the firm reviews a couple thousand deals per year and completes about half a dozen.[2](https://labusinessjournal.com/finance/march-capital-partners-closes-300m-fund-ii-adds-tw/) In February 2023, Leidheiser announced March Capital's $650M+ Fund IV, which the firm describes as focused on AI/ML, cybersecurity, and cloud/data infrastructure, from venture to early growth.[4](https://www.linkedin.com/in/jedleidheiser)
## Notable investments and boards
Leidheiser's current investments listed on his profile are Expel, Immuta, SpyCloud, and Unqork.[4](https://www.linkedin.com/in/jedleidheiser) His board roles are at three cybersecurity companies: as board investor at Expel since January 2021, at [Immuta](https://www.edgepedia.org/immuta) since January 2021, and at SpyCloud since January 2017.[4](https://www.linkedin.com/in/jedleidheiser)
The best-documented deal is Expel. On November 18, 2021, March Capital announced its investment in Expel's $140 million Series E. Expel operates in Managed Detection and Response (MDR), a market March sized at $15 billion or more, in which Forrester ranked Expel the number one choice.[5](https://marchcp.com/expel-simplifying-security-a-15b-opportunity/)
His profile also lists exits he supported: [CrowdStrike](https://www.edgepedia.org/crowdstrike) and KnowBe4 through their IPOs, and four acquisitions, with Mesh7 and VeloCloud acquired by VMware, Perspica by Cisco, and Tessian by Proofpoint.[4](https://www.linkedin.com/in/jedleidheiser)
## Public positions and recognition
Leidheiser appeared at an Investor 360 roundtable interview on June 15, 2022, where he was described as a partner with over 15 years of enterprise experience.[3](https://stubbsalderton.com/join-us-for-the-next-investor-360-roundtable-interview-with-jed-leidheiser-of-march-capital/) His public commentary is largely through LinkedIn posts announcing fund raises and portfolio milestones, including the Fund IV announcement in February 2023 and portfolio updates such as Expel's growth figures.[4](https://www.linkedin.com/in/jedleidheiser)
## Recent developments
Two milestones stand out. First, March Capital's $650M+ Fund IV, announced in February 2023, extended the firm's strategy into AI/ML alongside its established cybersecurity and cloud/data infrastructure focus.[4](https://www.linkedin.com/in/jedleidheiser) Second, in October 2024 Leidheiser announced that Expel surpassed $100 million in annual recurring revenue with 50 percent year-over-year growth in FY24, and welcomed Kevin Mandia in connection with Expel's next phase of growth.[4](https://www.linkedin.com/in/jedleidheiser)
