The Defined.ai Story


Launched Defined.ai, the world’s leading online marketplace, where AI professionals are able to commission, buy, or sell AI training data, tools, or models.


We raised a US$50.5 million Series B round of funding, the largest ever Series B round to be raised by a female-founded AI company in the US. We were also featured in the Forbes Top 50 Best Startup Employers.


Officially named one of CB Insights’ ‘100 most promising AI startups’, the first half of 2019 saw us double our team to over 100 employees worldwide, obtain the coveted ISO 27001 certification and announce the launch of our brand new Neevo app. The year ended with another accomplishment: ranking in Forbes AI 50 Most Promising Artificial Intelligence Companies.


We closed an US$11.8 million Series A funding led by Evolution Equity Partners, opened an office in Tokyo, announced an Amazon Alexa Skills partnership, a product integration with IBM Watson Studio, and were designated as a featured vendor for Microsoft‘s co-sell program.


We launched Neevo, the human intelligence half of our product equation, opened our third office in Porto and releases an alpha version of our Software-as-a-Service (SaaS) platform.


We launched our smart data platform and received a seed round of US$1.1 million from investors that included Sony, Amazon Alexa Fund, Portugal Ventures and Busy Angels.


CEO Daniela Braga founded the company in Seattle, WA and opened an R&D center in Lisbon, Portugal.
