After 9 months of development

Originally posted on LinkedIn · March 6, 2026


After 9 months of development and several rigorous sprints, the Rosa Family has a new launch to share.

Today we're proud to introduce:

John McKeon Rosa
8 lbs, 11 oz · March 6, 2026

  • Shipping above projections.
  • Immediately disruptive.
  • Not yet taking meetings.

Strong early investor interest from grandparents.

A few early learnings from the first 24 hours:

  • Returns are immediate and wildly non-linear
  • Sleep appears to have been deprecated in this release
  • The emotional override protocol is real and I was not prepared
  • Hair was not on the roadmap. It shipped anyway. No complaints
  • Current go-to-market strategy consists primarily of crying

None of this would have been possible without my co-founder, Elle Rosa, who — when asked to provide a quote for this announcement — said:

“I cannot believe you are writing a LinkedIn post about this.”

She has since been included in the announcement.

John is currently pre-revenue, operating in stealth, and declining all inbound at this time.

But he is here.

And he is extraordinary.

We're excited about the roadmap ahead.

Onward.
