Happy Cog

Happy Cog was one of Stripe's first partners, and we've been shipping Stripe work for more than ten years. We're a US-based full-service design and development agency that operates globally, with clients that range in size up to the Fortune 100. Stripe regularly brings us into its largest and most complex accounts.

Our Stripe work includes Lloyds Accept for Lloyds Banking Group (a point-of-sale app for UK small businesses built on Tap to Pay, Terminal, and Connect), a Terminal card reader ordering flow for Mindbody that Stripe featured in a case study, point-of-sale apps for Capital One, and a real-time agentic payments wall we built for Stripe's global Sessions conference.

Our team works across Stripe's product line:

• Terminal and Tap to Pay, including Apps on Devices builds on the S700, S710, and T600
• Connect platforms and marketplaces (Bandcamp, Dave, Mindbody, Lloyds, and more)
• Billing and subscriptions (Harvard's Legal Bluebook, Unraid, and more)
• Financial Accounts (formerly Treasury) and Issuing
• Infor and other ERP integrations
• API modernization that moves older integrations onto PaymentIntents and Checkout Sessions without taking payments offline (Dave, Rocket Lawyer, Elastic Path, and more)

We have Stripe-certified implementation architects and developers on staff, and we design and build everything in house (native iOS and Android apps, web front ends, and the back-end services and reconciliation behind them). We work closely with Stripe account executives, Professional Services, and solution architects. You can read more about what we build at stripe.happycog.com.
