Welcome! I’m David Mytton, CEO of Arcjet, a software startup that helps developers protect their apps. I’m also co-founder of Console, a devtools newsletter which helps developers find the best tools.

I’m an angel investor in early-stage developer-first startups and I’m also working towards an Engineering Science PhD in sustainable computing at the University of Oxford. My research has been featured in The Times, WSJ, Financial Times, Fast Company, Computer Weekly, and Sky News.

From 2009-2018, I was Co-founder & CEO at Server Density, a SaaS infrastructure monitoring startup. I built the original product, including the open source monitoring agent and custom time series database used by 700+ customers to manage mission critical IT environments. I grew the company in the UK and US through bootstrapped revenue and subsequent VC funding through to exit in 2018 to a US edge computing business, StackPath. As part of the acquisition, I joined StackPath to lead Product Engineering across a suite of edge computing and security products, leaving in Dec 2019.

Whilst completing an Environmental Technology MSc at Imperial College London 2019-2020, I developed an interest in sustainable computing and continued that research on the sustainability team at Uptime Institute, a global data center advisory organization, between Dec 2020 and Nov 2021.

I also founded the HumanOps community in London, San Francisco, and New York with Facebook, Financial Times, Spotify, Yelp and PagerDuty aimed at discussing how to deal with the human side of system operations: on-call, incident response, stress, fatigue, post-mortems and human process design.

From 2018 to 2023 I was an Expert in Residence at Seedcamp (unpaid), a London-based seed fund with 450+ portfolio companies (who also funded Server Density, and are now also an investor in Arcjet).
