Rio Health Raises $4.5 Million Pre-Series A Led by Version One Ventures

Rio Health has raised $4.5 million in a pre-Series A round led by Version One Ventures, according to a report by BW Disrupt.

The round places Rio Health among the early-stage health companies to secure fresh capital with backing from Version One Ventures, a firm known for its early-stage investments. The deal marks a pre-Series A commitment — a stage companies typically use to prove product traction and expand operations before a larger institutional round.

Version One Ventures led the financing. The report did not disclose additional investors or a valuation for the company.

The fundraising signals continued investor appetite for health-focused startups at the earliest stages of the venture cycle. Pre-Series A rounds of this size often fund product development, early commercial expansion and team growth ahead of a full Series A raise.

BW Disrupt, which first reported the transaction, named the company, the amount and the lead investor. Rio Health's specific product line and revenue figures were not disclosed in the report.

For Rio Health, the $4.5 million provides runway to build toward a Series A conversation, with Version One Ventures now anchored as its lead early-stage backer.
