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.

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.
