Ever since I got to meet François, Christopher, Tyler and the entire Memfault team back in 2019, I've been blown away by how crisp the company's vision has been, along with its ability to execute. Focused entirely on equipping firmware and embedded developers with the tools they need to reliably deliver, observe and manage their releases on large fleets of devices, Memfault is quickly becoming a core tool in any IoT team's quiver. With Saagar from Stripes leading the company's Series B round, couldn't be more thrilled about the chapters ahead! Congratulations!
