Runner

Runner is an AI agent platform built around a simple idea: instead of one general assistant, run as many agents as you have customers, each one working a case through to completion. The workflow has three steps. You show Runner how your team handles a process; it validates new agents against a simulation built from your past cases until they match your best teammates across dozens of tests; then it deploys an agent per customer in whatever channel they use, such as email, text or phone.

Earlier messaging framed Runner as an AI chief of staff for founders. The current site has broadened that into an end-to-end process platform for sales, support, operations and finance. Instead of drafting a single follow-up email, Runner runs the whole collection process across every delinquent account; instead of reporting sign-ups, it walks every driver applicant through onboarding. The company cites examples like collecting on 500 past-due accounts with a first payment on a three-year-old invoice, and nearly a 5x lift in response rate (2.6% to 12.6%) for a rideshare driver-activation campaign.

Runner emphasizes control and safety: agents stop rather than guess on uncertain cases, sends are capped, most teams approve every message in the early weeks, and every action is recorded. It also lets you bring your own connectors and keeps your playbook, wording and data private, stating it does not train models on your data. You can set it up by adding a plugin inside Claude Code or talk to the team directly.
