About Loka

Loka is a Silicon Valley software consultancy with global impact, bringing innovations to market faster since 2004. We connect clients in high-precision industries like Healthcare, Life Sciences, Education and Logistics to the tech that empowers their most effective work. We believe what you develop matters and bet you do too.

In 2024 AWS named Loka Innovation Partner of the Year—the same year in which we achieved AWS Premier Tier and were named part of AWS’s inaugural Generative AI Competency class. In the 18 months prior we identified more than 200 GenAI use cases for clients ranging from Cameo to Blue Cross Blue Shield. After two decades based in the Valley, Loka operates at the bleeding edge of AI, ML, DevOps, Data and Design—and is being recognized by the most authoritative sources in the tech world.

Whether building chatbots trained on proprietary data, developing apps to hyper-specific brand requirements or helping biotech companies accelerate novel drugs to eradicate cancer, our full-cycle team of engineers, developers and designers find the solutions that fit our clients’ unique needs and steer them away from the ones that don’t. We work around the clock (literally—we count employees in 18 different countries across seven time zones) but take every other Friday off to recharge. Our Explore and Relo programs encourage Lokals to live and work in rising tech hubs around the world, igniting their curiosity and imbuing their output with global perspective. We are small but mighty, fully remote but fully engaged and always Monday ready.

If you’re a founder or leader, we can help you grow. And if you’re a talented engineer seeking an unconventional but high-achieving workplace, we’d love to work with you.
