About the company

Biolinq develops a biowearable platform with tiny under-skin sensors that monitor metabolic health, including glucose, by sensing multiple analytes. The sensors continuously collect data below the skin and transmit to an app or clinician for insights and personalized medicine. It differentiates by being a small, under-skin, multi-analyte system backed by university bioengineering research, not external wearables or single markers. Its goal is to gain regulatory approval and bring scalable, continuous metabolic health monitoring to patients.

Simplify's Take

What believers are saying

  • Biolinq closed a $100 million Series C on April 22, 2025, funding commercialization.
  • ADA 2026 data strengthened Shine after its 2025 FDA clearance, supporting physician credibility.
  • The new FDA category gives Biolinq a first-mover story against later needle-free entrants.

What critics are saying

  • Dexcom Stelo and Abbott Lingo already own OTC glucose monitoring in 2026.
  • Biolinq still lacks a predetermined change control plan, slowing future sensor upgrades.
  • If FDA or payers reject premium pricing, Biolinq stays a niche hardware company.

What makes Biolinq unique

  • Biolinq Shine won FDA De Novo on September 23, 2025, defining a new category.
  • Its autonomous, needle-free glucose sensor uses intradermal microsensors, not fingersticks or deep filaments.
  • Biolinq targets multi-analyte metabolic sensing, including glucose, lactate, and ketones, beyond single-metric CGMs.

Biolinq CEO predicts smart patches will dominate wearables after $100M Series C

Smart patches could become the next major wearables category after smartwatches and rings, according to Richard Yang, CEO of diabetes biosensor company Biolinq. Unlike watches that track digital biomarkers, smart patches monitor biomarkers linked to the body's internal chemistry. Biolinq raised $100 million in a Series C round in April 2025, bringing total funding to around $300 million. The company secured FDA de novo classification for its Shine biosensor in September 2025, making it the first needle-free continuous glucose monitoring device in the US market. The device uses microneedle arrays that only penetrate the skin's top layer. Yang says the consumer health domain is "hungry" for such technology. Biolinq plans to expand beyond diabetes monitoring, with future applications potentially tracking multiple health metrics simultaneously through semiconductor-based biosensor chips.

Biolinq raises $100M for glucose monitor

Biolinq, a California-based health tech company, has secured $100 million in Series C funding to advance its needle-free glucose monitor for Type 2 diabetes. The coin-sized patch uses electrochemical sensors to track glucose, lactate, and ketones without penetrating deeply into tissue. It also monitors sleep and activity, providing real-time feedback. The funding, led by Alpha Wave Ventures, will support development, U.S. regulatory submissions, and commercial rollout.
