About Siro

What We Do
We are building an AI Coach for field sales. 

The majority of the 5.7 million sales professionals in the U.S. work in field sales (i.e., any sales process involving a handshake), but most receive ZERO on the job coaching because it is too time-intensive for managers/mentors to watch reps out in the field. So even though sales reps can out-earn surgeons, corporate lawyers, McKinsey partners — the vast majority do not. 

We believe that with the right tooling, Field Sales can become the most accessible path to financial freedom.
Siro records reps’ in-person conversations and highlights the most critical moments to let reps hear how top performers handle difficult customer objections and empower coaches to support reps to a degree never before possible.

The Team
Joe and Jake are both engineers and top-performing salespeople. Educated at UPenn and Emory, have experience from McKinsey and Amazon, and met while building a previous sales tool that has helped over 100,000 sales reps.
We are a Grand Central Tech '21 company backed by the Alchemist Accelerator, Soma Capital (Cruise, Deel), The MBA Fund (Stanford, Harvard, Wharton MBA Investing fund), Range Funds, Longrun Capital, and notable angel investors such as Steve King (DocuSign CEO) and Ryan Davis (BacklotCars Co-founder). 
A Warning
Nobody has accomplished what we have set out to do. The journey won’t be easy, but we’re well on our way and have a plan. If this is exciting to you, let’s talk.
