Who they are
Co-founder of Intercom, the Dublin-born customer messaging company that became the default in-app support layer for SaaS. Along with Des Traynor, Eoghan (commonly Eoghan McCabe/McCarthy in founder lore) shaped Intercom's design-first, opinionated product culture and later returned as CEO to steer the company into its AI-agent era with Fin. A founder-operator whose arc — build, hand over, come back — is worth studying for any SaaS CEO thinking about their own tenure.
Core Ideas
- Opinionated products — strong defaults beat infinite configurability
- Founder-led return — when the original operator is the right person for the hard phase
- Design-first SaaS — shipping craft as a go-to-market lever
