Five months ago, Ambi Robotics emerged from stealth with a $6 million raise. Today the Bay Area-based firm is back with several times that, announcing a $26 million Series A, led by Tiger Global. The new round also features participation from existing investors, including Bow Capital, Vertex Ventures US and The House Fund.

The startup first hit our radar through the involvement of UC Berkeley (and frequent TC Sessions: Robotics guest Ken Goldberg). Ambi operates in the pick and place robotics space — it’s a crowded category, but one with an intense level of interest, as more warehouse and fulfillment centers are accelerating toward automation after the shutdowns of the past year.

Ambi has already enlisted some high-profile partners, including Pitney Bowes. In spite of only coming out of stealth in April, the robotics startup began deploying its first systems — including the AmbiSort and AmbiKit — in October of last year, ahead of the massive holiday rush.

The company’s primary differentiation is in the AI that powers its picking robotics system.

“Ambi Robotics combines cutting-edge AI technology with engaging user interfaces to transform the role of ‘item handlers’ to ‘robot handlers,’ ” CEO Jim Liefer said in a release. “With our Series A funding, we will be able to empower more companies to help their associates work harmoniously alongside robots.”

This latest round will go toward scaling both the systems and the team of humans that build them, and deploying additional units.
