We achieve in 6 months what it takes our competitors 4 years to do. In just 12 months, 20 million patient consults were supported by Heidi, and were now powering more than 1 million consults every week.

With our most recent $16.6MM round of funding from leading VC firms, were geared up to supercharge our ambitious global growth, starting with the US, Canada, UK and Europe - and we need great people like you to get there. Ready for the challenge?
