About us

Merging Silicon Valley excellence with world beating Sri Lankan engineering talent

We help tech companies scale rapidly by providing them with dedicated, remote software development teams that excel in timely and high quality delivery.

Our Story

Our story began in 2002, when Mangala Karunaratne left Silicon Valley and moved back to Colombo, the city he grew up in as a child. A builder at heart, Mangala set up Calcey with the aim of solving a problem he faced in the Valley—the difficulty of building software quickly and without booking a trip to the ER for stress-induced ailments!

At home in Sri Lanka, Mangala found a ready talent pool of award winning engineers who had made it a habit to punch way above their weight, and were a living testament to the value of the elusive ‘10x Developer’. Armed with cups of Peruvian coffee, Mangala and the team set out on the adventure of a lifetime, building world-class software products for global clients.
