The most bioactive moment in human biology. Preserved.

Precision preservation of nature's most complex biological material.

Seven biological fractions. Each one optimized.

Your placenta is the most complete nutritional source your body produces during pregnancy — proteins, growth factors, hormones, minerals, and living stem cells, all in one tissue. Mothers have known this for generations. We now have the science to process each fraction for the route your body can actually use. The living cells get banked — for you, your family, or donated for research. Nothing gets wasted.

The Problem

Here's what's being thrown away at every birth.

The placenta is the most molecularly complex biological material the human body produces. It contains mesenchymal stem cells, the highest hormone concentrations of a woman's lifetime, growth factors in concentrations unique to placental tissue, and living cells that will never be reproducible from any other source. Thousands of mothers already encapsulate their placentas every year — and report real benefits. But whole-tissue processing treats every fraction the same, even though each one needs something different.

Proteins Need Acid

Collagen, fibronectin, and elastin need stomach acid to break down into usable peptides. That same acid destroys the growth factors sitting right next to them in a whole-ground capsule. One needs the environment that kills the other.

Growth Factors Need Protection

EGF, VEGF, and other signaling molecules need enteric protection to survive transit through the stomach. But enteric coating blocks the very acid your proteins need. You can protect one or digest the other. Not both.

Living Cells Need Cold

Freeze-drying preserves molecular content beautifully — but it can't keep living cells alive. The maternal stem cells in your placental tissue, available only from this one birth, need cryopreservation — a step that traditional processing wasn't built to include.

Mothers have been doing this for a reason — it works. The science now lets us understand why, and optimize each fraction instead of processing them all as one.

The Moonbox Approach

Your biology. Optimized.

Think about what's actually in placental tissue: structural proteins, bioactive peptides, growth factors, hormones, minerals, and living cells. Each one is processed differently by the body. Each one needs a different preservation method and a different delivery route. This is what we do.

01 Structural proteins Standard capsule — benefits from normal digestive enzymes

02 Bioactive peptides & exosomes Enteric-coated — protected through the stomach

03 Growth factor concentrate Alternative delivery — bypasses GI degradation

04 Iron & mineral fraction Timed-release — avoids absorption competition

05 Hormone fraction Labeled separately — your choice to include or exclude

06 Lipid & fatty acid fraction Soft-gel — protects oxidation-sensitive molecules

07 Stem cells Cryopreserved at −196°C — banked for you, your family, or donated for research

Modern methods make full utilization possible for the first time. Refined extraction and cryopreservation allow us to isolate living stem cells from placental tissue and preserve them at −196°C. These are your own mesenchymal stem cells — available for future therapeutic use, family members, or donated for research.

What We're Building

The science we've been waiting for. Applied to the tissue we've been wasting.

Fractionated Capsule Kit

True lyophilization — not heat dehydration. Trehalose stabilization to preserve molecular integrity. Sequential separation so each fraction gets the capsule type and coating it actually needs. You receive a complete labeled kit, not a single undifferentiated pill.

Fractionated, not whole-ground
Each fraction labeled with contents and delivery rationale
Professional processing under rigorous protocol
Pathogen testing included

Maternal Stem Cell Banking

Your own mesenchymal stem cells, from your own placental tissue, cryopreserved at −196°C. This is a one-time collection window. Once the placenta is discarded, these cells are gone. We think that's worth preserving.

Your own cells, from your own tissue
Cryopreserved at −196°C in liquid nitrogen
Available as an add-on to capsule processing
A preservation option that traditional processing can't provide

Roadmap

2026 Fractionated capsule service. Immediate postpartum nutrition from your own biology.

2027 Stem cell cryopreservation. Banking for future use, family therapeutics, or research donation.

2028+ Moonbox for Home. Personal device for monthly processing of menstrual blood — freeze-drying and encapsulation at home.

Pricing in development. Waitlist members will receive first access and founding member pricing.

Why Now

The window is opening.

The first menstrual-blood stem cell startup just raised in San Francisco. Investors are paying attention to this category for the first time since 2007.

Research on mesenchymal stem cells from birth tissue has accelerated dramatically since 2020, with GMP manufacturing benchmarks and large-scale clinical data now published.

Postpartum maternal health is finally receiving institutional attention—from employers, insurers, and investors. The care gap is recognized, not just felt.

Lyophilization and exosome science have matured enough to make fractional processing commercially viable—not just scientifically interesting.

Waitlist

Reserve your spot.

We're reserving processing slots for 2026 and 2027 births. We're also building a network of doulas, midwives, and birth workers who want to offer their clients the next step in placental science. If that's you — in either role — we'd love to hear from you.

Moonbox is pre-launch. We are completing regulatory review with specialized life-sciences counsel, building tissue processing partnerships, and assembling this waitlist before investor conversations. We've studied the landscape — cord blood banking, the recent wave of stem cell startups in San Francisco, the regulatory environment. We know what's been tried and where the gaps are.
