Company Overview

About Relay.app

Relay.app is a human-in-the-loop workflow automation platform founded in 2021 in San Francisco. The company was built around the insight that fully automated workflows break down at the edges — when decisions require human judgment, context that only a person has, or approval before an irreversible action. Relay.app's core design principle is that AI agents and humans should collaborate in workflows rather than the AI operating autonomously.

Business Model & Competitive Advantage

The platform connects to 100+ applications including Salesforce, HubSpot, Slack, Gmail, Notion, and Airtable, enabling teams to build complex cross-app automations with embedded human checkpoints — approval steps, form fills, and manual decisions that slot naturally into otherwise automated flows. Relay.app's AI agents can draft content, classify data, extract information from documents, and make routing decisions, with humans stepping in only where judgment is needed. Target users are operations, revenue, and customer success teams at mid-market B2B companies.

Competitive Landscape 2025–2026

Relay.app raised a $35 million Series A in March 2025 co-led by Andreessen Horowitz and Khosla Ventures, validating its human-in-the-loop positioning in a market increasingly crowded with fully autonomous automation tools. The funding has accelerated the expansion of its AI agent capabilities and integration library. Relay.app competes with Zapier, Make, and newer AI automation platforms but differentiates through its thoughtful balance between automation efficiency and human oversight.
