“Can Substack become the financial and distribution OS for independent creators — monetizing all media formats (newsletters, podcasts, video, communities) while owning the subscriber relationship at global scale?”
Founded in 2017 as a newsletter-first subscription platform, Substack evolved into a multi-format creator media platform encompassing writing, podcasts, video, and live video. Its embedded finance story is tightly coupled to Stripe: all monetization (subscription billing, payments, payouts, tax) runs through Stripe's suite. Substack expanded internationally with localized multi-currency pricing, driving cross-border complexity that Stripe handles end-to-end. The 2025 Series C at $1.1B reflects a strategic bet on the creator economy OS narrative — turning Substack into the monetization, distribution, and community infrastructure for independent media.
Substack processes payments through Stripe Connect and Stripe.
Substack uses Stripe for FX and cross-border payouts.
