About Quantela
We are a technology company that offers outcomes business models. We empower our customers with the right digital infrastructure to deliver greater economic, social, and environmental outcomes for their constituents.
When the company was founded in 2015, we specialized in smart cities technology alone. Today, working with cities and towns; utilities, and public venues, our team of 280+ experts offer a vast array of outcomes business models through technologies like digital advertising, smart lighting, smart traffic, and digitized citizen services.
We pride ourselves on our agility, innovation, and passion to use technology for a higher purpose. Unlike other technology companies, we tailor our offerings (what we can digitize) and the business model (how we partner with our customer to deliver that digitization) to drive measurable impact where our customers need it most. Over the last several months alone, we have served customers to deliver outcomes like increased medical response times to save lives; reduced traffic congestion to keep cities moving and created new revenue streams to tackle societal issues like homelessness.
We are headquartered in Billerica, Massachusetts in the United States with offices across Europe, and Asia.
The company has been recognized with the World Economic Forum’s ‘Technology Pioneers’ award in 2019 and CRN’s IoT Innovation Award in 2020.
