Our Story

A letter from our founders:

When we started Symphony in 2007, we had a mission to build the workforce of the future - where neither borders, geography, nor citizenship stopped the best engineers globally from delivering world-class work that matters. We built thriving teams of engineers that empower entrepreneurs and executives worldwide to crack tough technology challenges and make their visions a reality.

We’ve evolved since those early days. Our full-time team has grown to over 500 incredibly talented technologists, and we went from working with start-ups in the Valley to also partnering with Fortune 5 category leaders globally. We expanded our tech stack and product capabilities. More importantly, as we’ve grown, we’ve kept our small-company spirit, and we’ve never lost our focus on people.


People build technology, and great teams build technology that really matters.

We build real, enduring partnerships that work within complex organisational structures for messy businesses, and we deliver real business value. We’re uncompromising on partnership and performance, and that means our teams push back when they have conviction and take accountability so we can experiment together and enjoy the ride.

The future of impactful technology work will come from deep partnerships and dedicated, distributed, end-to-end teams. We will continue working hard to be pioneers in this space so we can take on the most ambitious and impactful technology projects with kindness and curiosity.

We’re excited by the journey. Haris & Mux
