The Problem

We’re lazy.

We hate doing the same thing over and over again. We hate doing work that can and should be automated. We’ve suffered through it. We don’t even want to search for an answer – we want to be proactively told the solution.

The fastest-growing technical companies have a critical group of people that are dealing with this problem – the sales engineers, solution architects, customer success engineers and everyone they serve on revenue teams.

They’re inundated by questions from colleagues & customers. They are stuck filling out similar security questionnaires & RFPs. They spend hours writing “handoff” docs and completing prep for meetings. They’re still waiting for an answer that they asked a colleague yesterday.

This wasted time is expensive and makes providing great experiences to customers and prospects unnecessarily challenging.

This is what we’re solving. At Mash, we’re building the tools to help revenue teams at technical B2B companies scale the tier-one service they provide to customers and prospects. From an encyclopedic knowledge engine that pulls in information from all the scattered, siloed and messy sources, to the automation agents that proactively help before they know they need it.

Help us help them… be lazy!

We treat your time as the scarce asset that it is. We respect people being heads-down and having the time to get into a flow. Distractions and context switching are things we work to minimize. We have meetings for specific purposes, and leverage async channels when appropriate.
