Angel Investor Forum
150 Dolphin Road, Bristol, CT, 06010, United States
Overview
Angel Investor Forum is a group of investors who invest their own money in startup companies. Angel Investor Forum (AIF) was founded in 2004 in response to the growing need for an organized angel effort in Connecticut. Due to the widening gap in the capital markets, there is a shortage of funding available at the seed stage ($250K-$5M). This funding gap represents a great opportunity for investment in companies with substantial growth potential but an inability to attract venture capital. AIF members invest their time, talent and money in supporting companies with solid business models and their efforts to grow successfully.

- Clearcut Surgical
Led · Seed · Jan 2026
Clearcut Surgical develops a multifunctional surgical device designed to consolidate several operative tasks into one instrument, aiming to streamline procedures and improve surgical efficiency. The company positions its product for operating rooms that seek to reduce instrument swaps and associated procedure times. Details on commercial traction, revenue, or user adoption have not been disclosed, but Angel Investor Forum’s criteria suggest the product is at or near market readiness.

- Lynq
Participated · Seed · Jun 2017
Lynq developed the human compass, a device that uses GPS to enable private, peer-to-peer location and data tracking without cellular networks or infrastructure. Its core technology is a licensable software and network protocol that can be integrated into other devices to enable decentralized device-to-device communication of location, messages, sensor and other low-bandwidth data over miles. The company currently sells its people compass direct-to-consumer and to government customers, which were the primary sources of 2020 revenue. Lynq also completed a $1.7M presale that helped drive early interest and investor traction. Management says licensing the software will evolve into its primary, high-margin and scalable revenue stream, shifting focus from device sales. Near-term plans include growing the team, completing software development, announcing integrations and partnerships, and beginning integration of the technology into licensee devices while continuing device sales. Lynq makes peer-to-peer location devices that let individuals and groups locate each other anywhere, independent of phones, cellular networks, Wi‑Fi and maps. Its rugged, waterproof hardware supports up to 40,000 units in a small area without interference. The company plans a B2B2C rental rollout followed by direct-to-consumer sales targeting families and outdoor enthusiasts, and also aims for government customers. Successful betas were conducted at Telluride and other ski resorts, and additional tests are scheduled at theme parks and festivals. The technology is under evaluation for use in disaster relief, search and rescue, and stealth operations. Lynq was founded in October 2014, is an alumnus of the HAX hardware accelerator, and is led by CEO Dave Shor.

- ZetrOZ
Participated · Equity · Jun 2014
ZetrOZ develops miniature wearable ultrasound devices, including sam® (sustained acoustic medicine) and UltrOZ®, for accelerated recovery and pain management. The sam® device targets non-pharmaceutical, bio-regenerative alternatives within the roughly $62 billion U.S. pain management market. Early adopters of sam® include physical therapists, athletic trainers and athletes using it for overuse injuries such as tendonopathies and muscle strains. UltrOZ™ Elite with OZ Inside™ launched in mid-2011 for equestrian rehabilitation to treat common musculoskeletal conditions in horses. The company is led by co-founder and CEO Bryant Guffey and Chief Scientific and Technology Officer Dr. George K. Lewis. ZetrOZ received a $5M venture loan facility which it plans to use to expand marketing and sales of its wearable ultrasound products beyond the professional market and into the consumer arena. ZetrOZ develops Sam, an iPod-sized wearable that delivers ultrasound therapy through a patch to treat musculoskeletal and joint pain and to improve circulation. Sam is designed to be worn for four hours at a time and is described by the company as a sustained acoustic medicine device. The company secured FDA 510(k) clearance for Sam a few months before the raise. ZetrOZ has raised a little more than $2 million from angel groups and private investors, according to a Form D filed with the SEC. Named backers include Connecticut Innovations, Standard Oil Ventures, Angel Investor Forum, Mass Medical Angels, Boston Harbor Angels and Launchpad Venture Group. The funds are likely to be used to support sales, marketing and manufacturing, and the company says it will focus on educating the medical community and patients about its drug-free pain solution. The company was started by a pair of Cornell grads; co-founders include CEO Brant Guffey, CSO George Lewis and COO JoAnne Guarino. Prior to Sam, ZetrOZ launched an ultrasound therapy product for horses called UltrOZ in 2011. ZetrOZ has developed a small portable/wearable ultrasound system designed to treat pain in humans and animals. The patent-pending device delivers low-intensity, long-duration ultrasound therapy and is intended for use while patients sleep, move, or receive care in a doctor’s or physical therapist’s office. The system consists of a battery pack, transducers that provide the therapy, and disposable hydrogel patches that attach the transducers to the patient’s body. The product will be available for purchase by doctors and physical therapists and for patients to self-administer therapy. The company also markets UltrOZ, a system for the equine market designed to treat pain and reduce the need for invasive therapies. ZetrOZ is based in Trumbull, Connecticut and currently has a staff of 12.
