Zenflow: Funding, Investors & Team (Oct 2026)
Forty million men in the US and over 500 million worldwide suffer from urinary obstruction related to benign prostatic hyperplasia (BPH). Millions of patients do not see effective relief from drugs, yet decline to undergo an invasive surgical procedure with high risk of side effects such as sexual dysfunction. To meet this clinical need, Zenflow has developed the Spring System. The device is designed to be deployed in the urologist's office in a simple, atraumatic procedure. Ongoing clinical trials have shown positive results out to four years after treatment.
Zenflow has raised $99.7M across 3 funding rounds on record, the most recent a Series D of $52.0M announced in Oct 2026.
That round is above the $5.0M median round size for Health Care companies tracked on FundedIQ over the last two years.

About FundedIQ's Zenflow Funding Data
FundedIQ tracks announced funding rounds and refreshes this profile every week. Round dates, stages and amounts are normalised to a single format, converted to US dollars, and de-duplicated: two records of the same round announced days apart are merged, and two genuinely different rounds are kept apart on the amounts they disclose. Amounts shown are the disclosed figures only — a round announced without a number is listed and excluded from the total rather than estimated.
Employee counts are reported bands, not exact headcounts. Founder and executive names carry the job title on record. Anything we do not hold for Zenflow is left off this page rather than filled in.
