Join our team

Re:infer was born in 2015 as a spin-out from the world-leading AI research lab at UCL where our founders - machine learning PhDs and professors - met. We are backed by top tier investors such as Crane, Seedcamp, and IP group, who have invested in industry pioneers such as Blue Prism, UI path, and Salesforce. Since 2015 we have grown into a diverse team that includes cosmologists, entrepreneurs, consultants, and mathematicians.

Re:infer was created to make every conversation valuable. We use machine learning technology to understand massive amounts of communications data instantly - data that was previously getting lost or ignored as businesses struggled to process it all. Now, understand every conversation, and use that insight to bring teams together and businesses closer to their customers. By building closer connections, we drive efficiency and elevate customer experience.



Make every conversation valuable.



Build the world’s smartest platform to make every conversation efficient and actionable, effortlessly.



A world where every person is heard and no conversation is wasted.
