The story

Sequin began as Sync Inc, a narrow Stripe-to-Postgres data sync tool aimed at helping developers replicate their Stripe data in real time. It evolved into Sequin Labs, Inc., broadening the product to sync and stream events from multiple APIs (Stripe and others) to various database and messaging destinations (Kafka, Redis, SQS, Webhooks). The embedded finance angle was primarily infrastructure-level: Sequin helped fintech platforms keep their Stripe payment data in sync with their own databases for analytics and billing products. The company announced a shutdown date of October 23, 2025, signaling an inability to find a sustainable growth path.
