What Subtidal does
Subtidal is an early-stage private company that provides real-time harmful algal bloom (HAB) monitoring and end-of-season scientific root cause analysis for community-funded lake associations. Its core product is a lightweight, solar-powered buoy equipped with multi-depth water column sensors that continuously measure cyanobacteria levels and lake conditions, streaming data to a secure online dashboard and displaying a color-coded bloom risk light visible up to two miles across the lake. Each pilot partnership includes the buoy hardware, a season-long dashboard with bloom risk alerts and trend visibility, and a comprehensive scientific evaluation identifying the most plausible drivers of bloom activity (phosphorus loading, stratification dynamics, weather patterns, watershed inputs), delivered by a WHOI-affiliated science team led by co-founder Dr. Matt H. Long.
The company monetizes through an annual, quote-based pilot program subscription in which a small number of selected lake communities receive full-season monitoring and a year-end root cause assessment. The go-to-market is highly consultative: CEO Casey Wilson personally engages each lake association from first conversation through findings presentation, using Calendly-scheduled discovery calls and selectively converting pilots into multi-year partners (100% of 2025 Cape Cod pilot partners have committed to the 2026 season). The 2026 pilot program is being expanded beyond Cape Cod to additional lake communities nationwide.
Subtidal is a 2025 spinout from the Woods Hole Oceanographic Institution, founded by Casey Wilson (repeat founder, formerly of Spire and Wokai) and Dr. Matt H. Long (20-year WHOI veteran in biogeochemistry, ocean engineering, and fluid dynamics). The company operates with 1–10 employees, holds institutional support from NOAA, the National Science Foundation, and Schmidt Marine Technology Partners, and is positioned at the intersection of marine technology, environmental monitoring, and public-health-adjacent water safety.

Subtidal product offering
Product offeringCore offering
Subtidal combines proprietary solar-powered, multi-depth lake monitoring buoys with a real-time online dashboard and expert scientific analysis to give lake communities continuous visibility into cyanobacteria levels and harmful algal bloom risk. Each annual pilot partnership delivers a deployed buoy, live dashboard access with trend visibility, a color-coded visual bloom risk indicator visible across the lake, and an end-of-season scientific root cause evaluation identifying the drivers of bloom activity and management options.
Product overview
Subtidal is a single unified offering that combines hardware and software with expert scientific analysis to deliver real-time lake water safety monitoring and root cause bloom analysis. The core product consists of a solar-powered multi-depth monitoring buoy and a real-time online dashboard that streams cyanobacteria levels and bloom risk status to lake communities. Each pilot partnership includes the hardware deployment, continuous dashboard access throughout the season, and an end-of-season scientific root cause evaluation conducted by the company's Woods Hole Oceanographic Institution-affiliated science team.

Products and services
- Subtidal Monitoring Buoy A lightweight, solar-powered buoy deployed on lakes to track cyanobacteria levels and overall lake conditions at multiple depths from surface to bottom. The buoy streams data securely to an online dashboard and features a color-coded light visible up to 2 miles across the lake at night to reflect current bloom risk to the community.
- Subtidal Online Dashboard A real-time web-based dashboard displaying current cyanobacteria levels, bloom risk status, seasonal trends, and safety guidance for adults, children, and pets. Streams data securely from the deployed buoy and provides lake communities with continuous visibility into water quality conditions.
- Subtidal Pilot Program A full-season continuous monitoring partnership for lake communities that bundles buoy deployment, real-time dashboard access, bloom risk alerts, and a comprehensive scientific assessment of bloom drivers. Offered as a small number of selected partnerships per season, with co-founders personally engaging each partner.
- End-of-Season Root Cause Evaluation A comprehensive scientific evaluation delivered at season end that identifies the most plausible drivers of bloom activity in a specific lake, including phosphorus loading sources, stratification dynamics, weather patterns, and watershed inputs, with actionable management recommendations. Personally led by the company's Chief Scientific Officer.
