Overview

Brief is a San Francisco company, operating as Mocksi Inc., founded in 2024 and backed by a16z through its Speedrun accelerator (cohort SR005). Co-founder Drew Dillon previously built product strategy at Yammer, Fond, and Skedulo before starting Brief to address a problem he saw across fast-moving product teams: they could ship anything but struggled to decide what to build next.

The product reads connected tools such as Linear, Jira, Notion, Slack, GitHub, and Fathom, extracting decisions as they happen and linking them into a searchable "Product Graph." Engineers and AI coding agents query that graph from the IDE, Slack, CLI, or through MCP, so a request in Cursor or Claude Code can pull in the actual reasoning behind a feature rather than only the code that implements it.

Brief targets small, fast-scaling technical teams (roughly 8 to 15 people) who are already using multiple AI coding agents and need those agents to share context. Pricing runs Free for 50 AI credits a month, Pro at $49 per seat monthly billed annually, Teams at $89 per seat with a 5-seat minimum, and custom Enterprise plans.

Pros & cons

Pros

  • Perpetual free plan (50 credits/month) lets small teams try it without a purchase decision
  • MCP-native design plugs directly into the AI coding agents teams already use
  • Backed by a16z Speedrun, giving it early institutional validation
  • Founder background in product strategy at recognizable prior companies (Yammer, Fond, Skedulo)

Cons

  • Team is small (2-10 people per LinkedIn), so support capacity and roadmap pace may lag larger vendors
  • Value depends on how consistently a team logs decisions into connected tools; sparse input means a sparse graph
  • Per-seat pricing on the Teams plan (5-seat minimum) adds cost for small teams that only need a couple of licenses
  • Company only founded in 2024, so long-term product stability is unproven
