No Standard for Measurement
There is no clinical standard for measuring menstrual blood loss. This inefficiency burdens clinicians — and 88% of surveyed providers agree a better, objective standard is urgently needed.
Now accepting early access sign-ups
Too many women aren't getting the care they need for heavy periods.
The first clinically-validated, mobile-based system for objective measurement of menstrual blood loss.
The Problem
1 in 3 women live with heavy menstrual bleeding — most never get properly diagnosed.
For decades, women have been handed questionnaires and asked to guess.
Mental Health Impact
Heavy menstrual bleeding is linked to anxiety and depression at three times the population average. Without objective data, many are dismissed by providers, creating a cycle of self-doubt, emotional distress, and prolonged suffering.
SourceSerious Health Complications
Undiagnosed heavy bleeding drives iron-deficiency anemia, unnecessary hysterectomies, and missed diagnoses of endometriosis and fibroids.
Economic Impact
Heavy menstrual bleeding accounts for over $94B in lost productivity and healthcare costs each year in the US alone.

The Solution
The first digital system for objective measurement.
Quantiflow turns a smartphone camera into a clinically validated bleeding-measurement tool — at home, in minutes.
Photo-Based Measurement
Snap a picture of a used pad on our reference mat. Computer vision returns a precise blood loss volume in milliliters.
Track Over Time
A private, longitudinal cycle record. Share a clinician-ready report that replaces guesswork with data.
Clinically Validated
Validated against the gold-standard alkaline hematin assay across peer-reviewed studies.
Patent-Protected
Proprietary method and reference surface protected by issued and pending patents across major markets.
How It Works
Three steps. Clinical-grade answers.
01
Place pad on mat
Unfold a Quantiflow reference mat and lay your used pad flat.
02
Snap & analyze
Open the app and take a couple photos. Our algorithm measures in seconds.
03
Track & share
Log every cycle and export a clinician-ready report with one tap.
The Science
Built on rigorous clinical research
Every claim we make is backed by independent data — because women deserve evidence, not estimates.
2×more accurate than current clinical proxies for blood loss
100%sensitivity for clinically heavy bleeding (zero missed cases)
90%participant agreement that Quantiflow would help with HMB diagnosis
Published research
European Journal of Obstetrics & Gynecology
Association between menstrual pad usage, self-reported symptoms, and menstrual blood loss measured by the alkaline hematin method
Underscores the unreliability of current clinical proxies for MBL. Low correlation was observed between MBL and questionnaires, and pad usage and post-cycle hemoglobin had substantial overlap between HMB and non-HMB groups.

Co-founder & CEO
Asiyah Awais
"I've spent my career in medtech — from musculoskeletal sensing to neurotechnology — translating complex science into real-world solutions. Across both, the same gap kept surfacing: women's health was consistently under-researched. That pattern of critical, overlooked gaps ultimately led me to Quantiflow."
- Dual Master's at UC Berkeley & UCSF focused on MedTech commercialization
- Former founder of a wearable sensing startup; awarded $50K NSF I-Corps grant
Co-founder & CMO
Dan Burnett, MD
"As a serial medtech founder, I've spent decades building and scaling companies to address critical clinical needs — including founding Channel Medsystems, which developed a leading treatment for heavy menstrual bleeding. That question — why can't we quantify this? — ultimately led to Quantiflow."
- Founded 17 venture-backed medtech companies; $400M+ raised
- Inventor on 40 issued patents and 300+ pending applications
