The mental load of running a family has never been on the cover of Fortune, but it might be the biggest unpaid CEO gig on the planet. Calendars, dentist appointments, soccer practices, grocery runs, it is a nonstop board meeting without adjournment. Enter Ohai.ai, the New York-based famtech startup led by Sheila Lirio Marcelo, who has already proven she can turn the invisible grind of care into a billion-dollar business with Care.com. On August 19, 2025, Ohai.ai announced a strategic funding round led by Muse Capital, with founding partners Rachel Springate and Assia Grazioli-Venier bringing together a roster of investors that reads like a Hollywood premiere guest list meets a Davos afterparty.
This is not your average check-writing exercise. The backers include Wisdom Ventures, Olivia Munn, Mindy Kaling, Abby Wambach, Jenny Mollen, Hannah Bronfman, Monique and Melvin Rodriguez of Mielle Organics, Sarah Harden of Hello Sunshine, Lavinia Errico of Equinox, and Abby Miller Levy of Primetime Partners. Add in returning early believers like NEA, Eniac Ventures, Bright Ventures, LifeX Ventures, and Amy Griffin of G9 Ventures, and you’ve got a syndicate that understands both the economics of AI and the emotional equity of family life.
Ohai.ai’s product, simply called “O,” is not a gimmicky gadget or a Silicon Valley toy. It is a household operating system that lives over SMS and web, with a mobile app on the way. O doesn’t just tell you what’s on your calendar; it syncs with over 67,000 school calendars and 27 million local events, cleans up scheduling conflicts, handles Instacart grocery orders, parses email to catch that orthodontist appointment you forgot to reply to, and quietly fills the white space families didn’t even realize was stealing their sanity. The system is designed to handle 90% of tasks with AI while relying on human assistants for the tricky 10%, keeping the machine sharp and the experience trustworthy.
This isn’t Marcelo’s first rodeo. She took Care.com public in 2014 and sold it to IAC in 2020, a move that signaled the mainstreaming of care as a category. With Ohai.ai, the focus shifts to the mental load itself, the invisible project management families juggle every day. That’s where the market is hungry. Families do not need another shiny app; they need an actual relief valve. At $26.99 a month, O positions itself less as a luxury than as the subscription that pays for itself by keeping parents sane.
The funding will fuel deeper product development, a school calendar upload feature that already looks like a secret weapon, and integrations that expand into ridesharing and home services. The strategy is clear: become the personal operating system for every household. The early traction shows thousands of families already using the system, with hundreds of thousands of events processed. That is not hype, it is proof of need.
Sheila Lirio Marcelo has always built companies at the intersection of tech and humanity. With Rachel Springate and Assia Grazioli-Venier pushing capital and vision into the mix, and a cast of cultural icons betting on the mission, Ohai.ai is not just automating chores. It is putting the cognitive load of family life into a machine that finally understands what it means to keep a household running. That’s not just innovation; that’s liberation with an API.
