Its pitch since 2008 has been that a legal, convenient service can beat piracy and win paying users.

The company is headquartered in Stockholm, Sweden.

The company is headquartered in San Francisco, California.

Spotify Technology S.A. and Substack Inc. pursue distinct approaches to generating revenue, and understanding how each company operates is the foundation of any fair comparison between Spotify Technology S.A. and Substack Inc..

Spotify Technology S.A. business model: Spotify runs a freemium model. Premium subscriptions (individual, Duo, Family, Student and other plans) generate about 90% of revenue: in Q2 2026 Premium revenue was ~$4.89 billion (EUR4.331 billion) against ~$504 million (EUR446 million) of ad-supported revenue. The free tier monetises through audio, video and podcast advertising and acts as the main funnel into paid plans. The largest cost is royalties paid to labels, publishers and other rights holders, so profit depends on raising ARPU (EUR4.89 per month in Q2 2026), marketplace programmes such as Discovery Mode, and higher-margin formats such as podcasts and audiobooks.

Substack Inc. business model: Substack is free to use for free publications. When a writer turns on paid subscriptions, Substack takes 10% of the revenue and Stripe charges its standard card fees. Substack does not run ads on publications. Revenue therefore scales with creator earnings, which is why the company invests in discovery features (recommendations, Notes, the app) that help writers sell more subscriptions.

The durability of a company's moat often decides long-term winners. Here is how the competitive advantages of Spotify Technology S.A. stack up against those of Substack Inc..

Spotify Technology S.A. competitive advantage: Spotify's advantages are scale, personalization and reach. With 777 million monthly users it has more listening data than any rival dedicated to audio, which feeds features such as Discover Weekly, Daylist and AI DJ. It runs on phones, desktops, consoles, cars, TVs and smart speakers from competing ecosystems, and cultural moments such as Wrapped turn usage data into marketing. The free tier gives it a conversion funnel that subscription-only services lack.

Substack Inc. competitive advantage: Substack's core advantage is distribution: its app, Notes feed and cross-publication recommendations help writers gain subscribers inside the network, which standalone email tools struggle to replicate. Writers also keep their mailing lists, which lowers the risk of joining.

Future prospects matter as much as current results. The growth strategies below explain how Spotify Technology S.A. and Substack Inc. each plan to expand from here.

Spotify Technology S.A. growth strategy: Spotify is growing along three lines: pricing and plan mix (price increases lifted Premium ARPU 7.4% at constant currency in Q2 2026), new formats (video podcasts, audiobooks in Premium, and partner video such as the September 2026 Genius series deal), and fan products such as Reserved, a Live Nation-backed early ticket access feature launched in the US in 2026. Management says it will keep a high bar for investments while reinvesting in AI-driven product development.

Substack Inc. growth strategy: Substack's growth strategy centres on making its app a destination rather than just an email tool: Notes, recommendations, video and livestreaming give readers reasons to open the app and help writers find subscribers internally. It also recruits creators from other platforms, including a reported $20 million fund launched in 2025 to attract video creators.

A closer look at the financial trajectory of Spotify Technology S.A. and Substack Inc. rounds out the comparison.

Spotify Technology S.A.: Spotify's 2025 Form 20-F reports EUR17.186 billion in revenue, EUR2.198 billion in operating income and EUR2.212 billion in net income, compared with EUR15.673 billion, EUR1.365 billion and EUR1.138 billion, respectively, in 2024. Operating cash flow was EUR2.933 billion in 2025; Spotify's separately defined, non-IFRS free cash flow was EUR2.874 billion after capital expenditure and restricted-cash adjustments. The latest quarterly release, for Q3 2026, reported approximately EUR5.0 billion in revenue, EUR672 million in operating income and a 33.0% gross margin. Spotify had 306 million Premium subscribers and 788 million monthly active users at quarter end. These quarterly figures are not a full-year 2026 result. The company reports in euros; its market capitalization changes with the share price and is not a measure of annual revenue or profit.

Substack Inc.: 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.
