Gander Robotics, a Cambridge-based developer of hand-throwable autonomous underwater vehicles for man-overboard rescue, has raised $1.1M in pre-seed funding co-led by Impellent Ventures and Underscore VC. The company builds the Autonomous Rescue Swimmer (ARS), an AI-powered drone that deploys flotation, flares, and beacons to locate and sustain overboard victims. The capital will accelerate prototype development and testing with naval, USCG, and commercial operators.
Navy AUV Contracts Spark Investor Interest
The round closes amid a March 2026 surge in US Navy autonomous underwater vehicle activity. Cellula Robotics won a Defense Innovation Unit contract for an AUV prototype on March 25, while L3Harris secured a deal for lithium-ion batteries enabling longer missions on the same day per Naval Today. Gander's throwable design targets search-and-rescue gaps overlooked by larger surface or tethered competitors.
Man-Overboard Survival Rates Lag
Man-overboard incidents claim most victims due to detection delays in rough seas. US Navy personnel face a 28% survival rate, dropping to 17% on cruise lines, with 72% of Navy cases fatal per Gander Robotics. The USCG logged 14,000 rescues in FY24 alone. Current protocols rely on visual searches by swimmers, costing precious minutes.
Throwable Drones Bypass Visual Limits
Gander's ARS launches from any vessel with a hand toss, using AI-enabled sonar to detect victims in low-visibility conditions. It deploys an auto-inflating flotation device, high-visibility flare, and RF beacon without human intervention. Built from commercial off-the-shelf components, the modular system scales for naval and commercial fleets.
AI Sonar Enables Seconds-Scale Response
Unlike tethered ROVs from Blueye Robotics ($7M raised) or surface-focused Maritime Robotics ($12M raised), ARS operates fully autonomously underwater. This addresses protocol delays where no visual search or swimmer is needed, cutting response from minutes to seconds.
As CEO Michael Autery noted:
"Every sailor and mariner in the world knows the fear of a man-overboard call."
VC Operators Back Navy Veteran Duo
Impellent Ventures, an emerging East Coast firm with deep tech bets like Trace 3D, co-led alongside established Underscore VC, which has robotics thesis and exits like BastionZero to Cloudflare. Underscore Partner Lily Lyman highlighted the founder-problem fit in their investment thesis per Underscore VC. The backers signal conviction in non-kinetic defense robotics.
AUV Market Scales to Billions
The autonomous underwater vehicle market stands at $3.78B in 2026, projected to reach $14.51B by 2033 at 19.1% CAGR per Precedence Research. Military UUVs hit $4.62B this year, growing to $8.72B by 2030 per GlobeNewswire. Competitors like Saronic ($600M+) focus on combat vessels, leaving SAR niches open.
MIT Sweep Validates Founders
CEO Michael Autery, a US Navy ocean engineer with MIT Sloan MBA and MS thesis on AI AUVs, pairs with Harvard robotics engineer Lael Ayala. The duo swept MIT's $100K competition, winning first prize and audience choice—the first team ever per LinkedIn. Their Navy and hardware expertise drives ARS from thesis to prototype.
Accelerators Fuel Prototype Push
Post-raise, Gander joins MIT's The Engine residency and Harvard's QLab national security accelerator. Funds target prototype iterations ahead of Technology & National Security Conference showcase per Finsmes. Selection as one of 20 ventures signals defense ecosystem buy-in.
