About Micah Smurthwaite
Micah Smurthwaite is a partner at Next47, a venture firm that backs enterprise founders. Next47 bios say he joined in 2020, first in Palo Alto and later in London. Before that he was the first sales hire at Cloudflare, where, per his Forbes and Next47 bios, he was part of the team that grew revenue from $1M to over $100M. Crunchbase lists his Cloudflare role as Head of Channel Sales from 2013 to 2017.
Crunchbase says he attended Harvard Business School. He has also been a Venture Partner at Alchemist Accelerator, helping founders grow revenue. He has written on go-to-market for Forbes and TechCrunch, including a TechCrunch piece arguing that a startup's first sales hire should be a missionary rather than a mercenary.
Crunchbase lists him as a board observer at Aforza and Armorblox. One data aggregator describes him as a startup investor and advisor since January 2024. Other sources still list him as a Next47 partner, so confirm his current affiliation before you pitch.
Most of his public record comes from his role at Next47, not from personal angel checks. Crunchbase counts 5 investments under his name. Its latest listed investment is the Series A in Arcjet. Which deals were personal angel investments and which were Next47 deals is not clear from public sources.
The Lounge deals desk shows two AI rounds from June 2026: Tolmo's $22M seed and Structured AI's $4.2M seed. Crunchbase lists him as an investor in Tolmo, an AI security platform for cloud applications. Dealroom data says Accel led the round, with Y Combinator participating. NFX Signal lists him as a co-investor alongside Charlie Songhurst on Structured AI. Structured AI builds AI quality assurance for construction drawings, and FCVC led its seed.
Crunchbase also lists him in the pre-seed round of Alpic, a cloud platform for building and distributing MCP servers and ChatGPT apps.
His bios say he invests in enterprise software, infrastructure, cybersecurity, network infrastructure and frontier technology companies. He has said these are growing fast in Europe, and he has been based in both the US and London. NFX Signal tags his interests as AI, cybersecurity, cloud infrastructure and enterprise applications at seed and Series A, plus robotics, IoT, logistics and manufacturing.
NFX Signal gives an investment range of $100K to $5.0M for his Next47 position. This is not a stated personal angel check size, and he has not published one.
