Mattermore is an early-stage artificial intelligence startup building a copilot for business-to-business sales managers, with a focus on remote teams selling software-as-a-service products. The company was founded roughly one year before the November 2023 interview and remains pre-revenue, sustaining operations through consulting, coaching, and training work performed by co-founder Matt Shenker. The product is designed to aggregate data from CRM platforms, outreach tools, asynchronous communication channels such as Slack and Microsoft Teams, and call transcripts, then surface actionable guidance for sales managers. At the time of the interview, the company had a founding CTO newly on board and expected an internal MVP within two weeks, with a publicly accessible MVP projected six to nine months out. Mattermore reached its early beta user base through a structured discovery process, conducting six-week interview sprints with 100 sales teams per batch across four consecutive batches. The company has not yet asked beta users to pay and has not disclosed any funding round.
