Platform Market: AI Writing Startup Marker Raises $13M Seed Funding
London-based AI writing startup Marker has emerged from stealth after securing a $13 million seed funding round led by Index Ventures, with participation from LocalGlobe and high-profile angel investors. Co-founded by Jon Steinback (former DeepMind creative lead) and Ryan Bowman, Marker is building a collaborative, AI-powered word processor designed to assist writers during the drafting and editing process rather than generating automated content. The startup aims to offer creative tools that value writing craft, countering industry concerns over low-quality AI-generated content or "slop."
