Financial Analysis
Substack is private and publishes no audited financials. Its revenue comes mainly from a 10% fee on paid subscriptions sold by creators. Newcomer reported in 2025 that Substack told investors it had about $45 million in annual recurring revenue. Funding includes a $15.3M Series A led by Andreessen Horowitz (2019), a $65M Series B at a reported.1B valuation (2021), roughly $7.8M from a 2023 Wefunder community round, and a $100M Series C led by BOND and The Chernin Group at a $1.1B valuation (July 2025). That valuation implies a revenue multiple of roughly 24x on reported ARR.
