Rion found that culturing stem cells in a lab to force division leads to rapid DNA damage, as cells are not designed for this artificial environment. This damage created inconsistent exosome products, making large-scale, uniform manufacturing from stem cells unfeasible and prompting a search for a more stable source.

Whey, once a low-value byproduct of cheesemaking that was often fed to pigs or spread on fields, is now a highly profitable product. Modern cheese plants are designed specifically to harvest and process whey into high-demand whey protein isolates, fundamentally changing the business model of cheese production.

By partnering with Fujifilm Cellular Dynamics (FCDI), the company that developed its core technology, Kenai avoids a costly and risky tech transfer process. FCDI's existing facility can handle both clinical and future commercial scale-up, a significant operational and financial advantage.

Rion strategically chose diabetic foot ulcers as its lead indication to de-risk its new therapeutic class. This "outside-in" approach allows the company to build a substantial safety record and gain regulatory and clinical acceptance with a topical product before advancing to more complex systemic applications.

Rion structures itself as a central "hub" with core technology, then creates separate "spoke" companies for verticals like veterinary or cosmetics. These spokes raise their own targeted capital, allowing Rion to fund platform development without constant dilution at the parent company level and diversifying funding risk.

Unlike many cell therapies, Rion's platelet-derived exosomes are devoid of the self/non-self surface markers that trigger immune rejection. This "immune privilege" is a critical biological advantage, allowing the product to be used as a universal, off-the-shelf therapy for any patient without needing donor matching.

Unlike typical tech disruption, healthcare often requires collaboration. Startups effectively "rent" distribution and patient access from incumbents. In return, incumbents "rent" cutting-edge innovation from startups, creating a necessary symbiotic relationship.

Rion's research, initially focused on stem cells, revealed their regenerative properties were not intrinsic. Instead, the cells were recycling platelet content from their culture medium, and these recycled components were the true source of the therapeutic effect. This finding prompted a strategic pivot away from stem cells.

Selling low-cost vaccines to organizations like Gavi isn't just charity for pharmaceutical companies. It creates massive economies of scale, lowering the cost of goods for their high-margin primary markets and increasing overall net profit, creating a powerful win-win incentive structure.
