This founder made millions when LinkedIn bought his start-up—but the stress landed him in the hospital. Now he’s built another $825 million brand
Fortune 21
Rahul Vohra was hospitalized in 2011 after stress from running his startup Rapportive for a potential LinkedIn acquisition culminated in gastrointestinal reflux disease. The LinkedIn deal for Rapportive was reportedly valued at $15 million in February 2012, and Vohra later launched Superhuman. He rebuilt his work routine around diet, exercise, and transcendental meditation, then went on to build a new $825 million business that was acquired by Grammarly in 2025.
