About Sesamy
Built by the team behind Acast. Built for publishers.
Sesamy was built by the team that founded Acast, the world's largest podcast platform. The company launched in October 2022 and today powers subscription management for four of the six largest digital magazines in Sweden.
The story
We know what it takes to build media infrastructure that scales.
The team behind Sesamy spent years building Acast from a startup to the world's largest podcast platform. We learned what it takes to build infrastructure that media companies depend on every day: reliability, speed, and the ability to evolve without breaking what already works.
When we looked at how publishers managed subscriptions, we saw an industry running on legacy software built for a different era. Print fulfilment in one system, digital in another, B2B in a spreadsheet. Bad UIs. Manual workflows. Vendor lock-in. We knew we could build something better.
Sesamy launched in October 2022. Within three years, four of the six largest digital magazines in Sweden were running their subscriptions on the platform. 80+ publishers have migrated from legacy subscription and print systems with zero downtime. Sesamy is founder-led, with the same team running product, engineering, and commercial today as on day one.
What we believe
Four rules that shape every line of code.
Not values posters. Principles you can test against the product, the contract, and the conversations you have with our team.
- Configuration over customisation.
- Publishers should not need developers to change their subscription setup. If it can be a setting, it should be a setting. Paywall rules, price tables, campaign windows, renewal notices, tax codes — all editable from the portal, with every change versioned and reversible.
- No lock-in. Ever.
- You own your Stripe account. You own your Vipps account. Full data export at any time in standard formats. No long-term contracts, no multi-year commitments that keep you paying after the platform stops serving you. We earn your business through the product, not through the exit cost.
- Honest about complexity.
- Migrations have unknowns. Integrations take work. Legacy data is messy. We tell publishers what to expect before the contract is signed — validation steps, failure modes, the actual timeline. This is how trust is built. Surprises after go-live are worse than hard conversations beforehand.
- Built for publishers, not for everyone.
- Sesamy is not a generic subscription platform. We know OCR/KID, Helthjem, DI, Billogram, and Nordic payment flows because our publishers need them. We ignore categories that distract from the publisher workflow. This depth is a choice, and it is why the platform fits where generic tools do not.
How we build
Every feature exists because a publisher needed it.
We do not build speculatively. We do not add features to win RFP checkbox competitions. Every major capability in Sesamy exists because a real customer needed it, and we built it together with them.
This co-development philosophy means the platform is shaped by actual publishing workflows, not by what a product team imagines publishers might want. It is why Sesamy handles the specific pain points other platforms miss: OCR/KID payment flows, print distribution lists with Helthjem and DI, legacy renewal notices, B2B seat management.
The platform is a living system. It continues to evolve because the publishers using it continue to push it forward.
