Circle Safe: Funding, Investors & Team (Sep 2026)
Atrial fibrillation is the leading heart rhythm disorder. The best method to avoid it coming back is by undergoing an intervention called ablation. Ablation can be done using Radiofrequency or Cryoballoon, with the latter being a newer, quicker, and simpler technique. However, Cryoballoon ablation carries the risk of causing Diaphragmatic Paralysis. Circle Safe is working on a solution to eradicate this complication entirely.
Circle Safe has raised $8.3M across 1 funding round on record, the most recent an undisclosed round of $8.3M announced in Feb 2025.
That round is above the $4.7M median round size for Health Care companies tracked on FundedIQ over the last two years.

About FundedIQ's Circle Safe 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 Circle Safe is left off this page rather than filled in.
