Childcare with a science experiment built in. Vetted sitters run the activity at the table.
Childcare that doubles as a lab. StemSitters pairs families with sitters who run a hands-on STEM experiment while they’re there.

Parents settle for “safe and occupied,” because “safe and curious” was never on the menu. StemSitters makes the sitter the experiment lead: vetted caregivers arrive with an age-appropriate activity, so hours you were paying for anyway turn into something the kid remembers.
Same sitter, same hours — but the kitchen table becomes a lab.
I framed the wedge and designed both sides of the marketplace.
Not “more childcare” — “better hours.” The experiment is the differentiator, not a feature bolted on.
Parents browse by activity and age; sitters list what they can run. Real activities, age-banded — not a vague promise of “enrichment.”
