Plato

Plato was a mentorship and leadership community for engineering leaders (platohq.com), operating from 2018 until its sunset on December 19, 2025. It ran a global network of 500+ engineering leaders and 1,000+ mentors, the annual Elevate conference, and dozens of meetups, webinars, and dinners. Its parent company Coda was acquired by Grammarly (rebranded Superhuman), which wound down Plato's programs to focus on an AI-native productivity suite. The company is now deactivated: platohq.com redirects to a Substack sunset announcement and no developer API, SDK, documentation, or integrations are or were published. Surfaced as a partech portfolio lead; enrichment found no API surface.

Plato is profiled on the APIs.io network. Tagged areas include Company, Applicative Saas, Mentorship, Engineering Leadership, and Community.
