43North in Buffalo awards $1 million each to five companies

Two of the five are from New York. All will move to Buffalo to grow their enterprises.

Five new start-ups earned investments of $1 million each and a place in 43North’s Year 11 cohort. They’ll soon relocate to Seneca One, where they’ll scale their businesses and help drive Buffalo’s start-up scene forward.

The five are:

  1. Cellsense of New York City. It transforms algae and cellulose into compostable beads that eliminate microplastics across the fashion and cosmetic industries.
  2. Cosi Care of London, U.K.. The company has created the world’s first medical devices that offer instant itch relief and a safe alternative to scratching and infection management for those living with eczema or any chronic itch.
  3. Floe of New Haven, CT. It offers a smart, cost-effective, and eco-friendly solution for ice and snow management on roofs.
  4. radEmploy of New York City. It is a radiology staffing platform that leverages conversational artificial intelligence (AI) to efficiently connect radiology professionals with large hospital systems, accelerating candidate placement.
  5. Tukki.ai of Miami, FL. The company combines AI and expert support to help immigrants and companies manage visas and green cards efficiently, improving speed, accuracy, transparency, and the overall experience.

Backed by New York State and supported by Empire State Development, 43North has become a driving force in Buffalo’s rise as a thriving start-up city. In addition to the $1 million investment, companies selected for 43North’s Year 11 cohort will receive mentorship, office space, access to a broad network of investors, and resources to help them scale successfully. Since 2014, 43North has invested in 74 companies, created more than 3,000 jobs globally, and raised more than $1 billion in capital.
