Substack has raised $100 million in fresh capital as it expands beyond its roots as an email newsletter platform and deepens its ambitions to become a full-fledged media network for independent creators. The Series C round, which values the company at $1.1 billion, was led by BOND and The Chernin Group, with participation from Andreessen Horowitz, Klutch Sports founder Rich Paul, and SKIMS co-founder Jens Grede.
The raise comes at a moment when Substack is seeing meaningful traction: over five million paid subscriptions, up from four million in late 2024, and a growing base of creators migrating to the platform amid broader uncertainty around social media algorithms and potential TikTok restrictions. For investors, it’s a bet on a business model that eschews traditional ad-led monetization for now and builds instead on direct audience relationships and subscription revenue. Substack takes a 10% cut of earnings from creators who charge for access to their newsletters, podcasts, or video content.
“This is about leaning into the long-term ambition,” CEO and co-founder Chris Best said in a recent podcast interview. “We’ve gone from a rinky-dink email newsletter company to a real network that’s taken on the world.”
