Juno Bio secures US$3.8m for precision diagnostics
Juno Bio has secured US$3.8m to expand its diagnostics platform for vaginal health and reproductive care.
The funding round was led by Ada Ventures, with participation from Artesian, Entrepreneur First and Illumina Accelerator.
The women’s health startup said the seed funding will support the launch of its first CLIA-certified sequencing laboratory in Oakland, California, and a new clinical vaginal microbiome and STI test for healthcare providers.
CLIA certification refers to US laboratory standards for testing human samples used in diagnosis, prevention or treatment decisions.
Dr Leighton Turner, co-founder and chief scientific officer of Juno Bio, said: “The vaginal microbiome is still one of the least understood systems in the body at a clinical scale.
“With our lab, we’re starting to build a measurement standard that clinicians can actually use.
“We believe the level of detail from this kind of testing can meaningfully improve how vaginal healthcare is provided.”
The company is developing precision diagnostics for vaginal health, where patients can experience recurring symptoms, inconsistent diagnoses and treatments based on trial and error.
Juno Bio said bringing testing in-house gives it greater control over the process, from sample handling to results, while allowing it to refine its technology and build what it says is one of the largest datasets focused on the vaginal microbiome.
The vaginal microbiome is the community of bacteria and fungi that naturally live in the vagina. Changes in this balance can be linked to infections, symptoms and wider reproductive health issues.
Juno Bio’s newly launched clinical test examines the wider vaginal microbiome and screens for four common sexually transmitted infections, or STIs.
Rather than looking for a single cause, the test is intended to give clinicians a broader picture of what may be contributing to symptoms.
Juno Bio says this matters because multiple infections can occur at the same time and microbiome changes may be linked to fertility, menopause or recurrent infections.
Dr Anna Powell of Johns Hopkins said: “Vaginal microbiome testing has the potential to significantly reshape how we understand and manage vaginal health, particularly for patients with recurrent or unexplained symptoms.
“While the field is still evolving, advances in sequencing and data interpretation are moving us closer to a future where more personalised, microbiome-informed care can complement existing diagnostic approaches.”
Check Warner, co-founding partner at Ada Ventures, added: “Juno Bio is setting a new standard for how vaginal health is understood and managed.
“What they’ve built at this stage, with this level of capital efficiency, is exceptional.
“We’re proud to support the team as they scale their clinical infrastructure and continue leading innovation in this critically underserved category.”
