Inaugural BlueTech Accelerator showcase highlights eight freshwater startups in Northern Michigan

What’s happening: Eight early-stage water technology companies pitched to investors at the inaugural Northern Michigan BlueTech Accelerator Showcase this month. The event concluded a seven-week accelerator launched by startup incubator 20Fathoms in partnership with national venture capital firm gener8tor. 

Supported by the U.S. Economic Development Administration’s Build to Scale program, the initiative provided founders with intensive coaching and mentor networks. The participating startups focus on protecting and managing freshwater, with innovations ranging from autonomous tunnel inspections and leak detection to agricultural irrigation automation and sonar fish tracking. To attract these businesses permanently, 20Fathoms and regional partners are offering a relocation support package to companies moving to the Traverse City area.

The startups: The inaugural cohort featured eight distinct innovators spanning the water cycle:

• AmHyTech: Enhances safety and affordability in storing and handling ammonia.
• CaptureTech: Uses recoverable Biochar Capture Packs to prevent harmful algal blooms.
• Ceretune: Leverages plants and biofilm to remove excess nutrients from water bodies.
• Effluent Technologies: Deploys physics-informed modeling tools to reduce water utility risks and costs.
• Growbud: Automates greenhouse and controlled-environment irrigation systems.
• H2O Connected: Minimizes multi-tenant property water waste via early toilet leak detection.
• Oprones: Inspects complex stormwater and wastewater tunnels autonomously.
• Thalweg: Processes raw sonar data into automated fish counts and tracking metrics.

What they’re saying: Organizers view the initiative as a major step toward transforming the region into a national hub for freshwater technology. “Just as Silicon Valley became synonymous with tech, Northern Michigan can become synonymous with BlueTech,” said Stacey Feeley, executive director of 20Fathoms. She added that growing the local BlueTech sector will generate high-paying jobs, attract fresh investment, and keep talented professionals in the region.

What’s next: The inaugural cohort will now look to leverage their newly expanded networks of investors, customers, and corporate partners to scale their operations. Regional stakeholders, including Traverse Connect, the Freshwater Research and Innovation Center, and Northwestern Michigan College, will continue building the local ecosystem to ensure Northern Michigan remains a top-of-mind destination for global water-tech founders.
