Serval
↗︎
New
Trusted by startup titans like Clay, Mercor and Perplexity to automate IT help desk functions and streamlines workflow processes. Serval is still gaining steam with a new funding round rumored to be in the pipes, a few weeks after raising a $47M Series-A led by Redpoint with participation from Bessemer, Box Group and others. Edit: Serval raised a $70M series B, led by Sequoia, one day after the list went live. Congrats.
