Otta's take on Fidel API

Sam Franklin headshot

Sam Franklin

CEO of Otta

Fidel is tackling the obstacles to accessing customer payment data, making it easier for developers to create smart solutions customers love, without the burden of complex integrations, cost or compliance traditionally found in the payments ecosystem.

The company has developed a suite of APIs that make it easy to link a user's payment card to an app and securely access real-time transactional data through a single access point. A key application is loyalty programs, where users can sign up, earn points rewards and cash back when using their registered card.

Recent funding secured will allow Fidel to continue developing its programmable experiences that facilitate the easy use of payment cards. The company has plans to scale its workforce to meet growing demand in the engineering, sales, and product departments. Indeed, it will accelerate investments into expanding product offerings across identity verification, consent management and payments.

Total funding - $85.7m

Company benefits

  • Flexible hours - Ideally, you arrive in the morning and go home in the evening, but a busy life can be unpredictable. We leave it to you to manage your time
  • No holidays tracking - For real. We understand you need some time off now and then. Maybe you want to visit one of our 20+ team members’ home countries?
  • Health insurance - Each Fidel API member receives a full Vitality insurance pack, giving you great health rewards whilst helping keep you in tip-top shape! It’s a win-win
  • Yearly off-site - From Napoli to Sitges, as long as it’s sunny, we’re happy! We’re not sure yet where we’ll be next year, but we do know it’ll be awesome
  • Educational resources - Everyday is a school day! We offer all Fidel API team members access to Udemy and Audible to grow themselves professionally across a range of disciplines

Company values

  • Be humble - We’re a team of learners. It’s more important for us to build the best product possible than to always be right. We listen to alternative opinions, let things go (even when we love them) and leave our egos at the door
  • Be honest - We’re open and honest in everything we do. We don’t hide behind language or tell half-truths. We don’t pass the buck or make excuses. We’re continuously building on our founding principles of trust and transparency; we know they’re essential to get us where we’re going
  • Be adaptable - We’re always listening — to our customers, to the market and to each other. We’re adaptable, agile, and open to trying new things. We never waver in our core mission, but we’re creative about how we get there
  • Be encouraging - We’re empowering the next generation of innovation and that means empowering the people behind them, too. We work together and we help each other out, because we want everyone to benefit from the ecosystem we’re building
  • Be a leader - We believe that passion breeds the best results. We stand up for what we believe in, run with ideas, and see projects through to the very end. We own our work, and we take pride in it
