Passage Health

The newest platform here, and one of the few whose funding is confirmed by filings rather than press releases.

The short version

Money raised
$10,225,000 filed, of which $1m was a note conversion2

Passage Health is the youngest company in this directory and, unusually, one of the easiest to verify. It filed with the SEC for both of its funding rounds, so the amounts are a matter of record rather than a press-release claim.1

Bill White and Gabriel Khaselev founded it in 2022. White has a personal connection to autism — he has described babysitting a nonverbal autistic child in his youth. The company says it engaged around a hundred ABA provider organizations while building the product.3

The seed round's first sale was in July 2023, at $2,225,000 — a filing which notes that $1,000,000 of that was existing convertible notes converting rather than new money. The Series A followed in April 2025 at $8,000,000. By its own account it was serving about 150 practices at that point.2

What we could not confirm 4 open questions
  • No investor is named in either filing — Form D discloses amounts and investor counts, not identities. One director on the filings is a partner at an investment firm, which sits awkwardly against describing the company as wholly independent.2
  • The two filings total $10,225,000, but $1,000,000 of the seed was notes converting. New capital raised is closer to $9.2 million, and we do not publish the larger figure as money raised.2
  • Gabriel Khaselev's background is not published beyond his title.2
  • Employee count and revenue have never been disclosed by the company; trade coverage put it at around nineteen full-time staff in May 2025.3
