Plugins are the new partnerships.

I'm Jarrett Mitchell. I spent ten years building partner programs and the systems behind them, from a startup through a $640M exit. Now I build open-source plugins for Hermes Agent, the layer where an outside company's product meets a real person's work.

Three things I built on Hermes. In each one the lit layer is where an outside company's product meets a real person's work. That layer is the surface for partnerships.

$640M

The exit I stayed through. Equifax bought Kount in 2021.

The work

Built on Hermes, in the open.

Stoa, the CRM for Hermes Agent

A small team runs its pipeline by talking to Hermes in Slack or the web app. Hermes logs the email, call and Slack activity and proposes the next step. A person approves it.

Nous maintainers reviewed it for the plugin catalog and asked for three changes. All three were in within three hours.

An agent a business runs on

A boutique recruiting agency runs its searches every day on a Hermes Agent I built and operate. The recruiter is not technical, works in Slack and Google Workspace, and never opens a terminal.

Its pipeline workflow became the blueprint for Stoa. Private deployment, so there is no screenshot here.

A day on that agent
  • Nightly backup of everything the agent knows
  • Health check, silent unless something is wrong
  • Morning brief lands in Slack
  • Sourcing research, pipeline updates and drafts, each one approved by the recruiter
  • Research suggestions for every open role

Photograph an item and bae drafts the listing: factual copy, real fee and shipping math, and category rules checked before anything goes live. Nothing reaches a live store until the seller approves.

Startup to enterprise

Startup to enterprise, through the exit.

I joined Kount as a startup, built its partner channel, stayed through the exit and led the integration that came next.

  1. Joined Kount, a fraud-prevention startup

    Worked directly for the CRO. Redesigned the API documentation.

  2. Launched the partner portal

    About 500 partner users, millions in revenue, and a referral program that turned partners into pipeline.

  3. Equifax bought Kount for $640M

    I stayed and kept building.

  4. Equifax bought Midigator

    Led the team that brought it into Kount, then into Equifax.

  5. Equifax Innovation Award

    Company-wide, for forecasting on usage-based products.

  6. eBay, and Hermes

    Operations manager at eBay. Two open-source plugins and a live deployment as personal projects.
