  • REGENT
    REGENT (w2021)Active • 40 employees • North Kingstown, RI, USA
    REGENT is building a new mode of transportation that will redefine regional mobility by mid-decade. Their first product, the seaglider, is an all-electric, hydrofoiling boat-plane that operates within a wingspan of the water's surface. By flying low on a cushion of air, seagliders unlock the ability to fly twice as far as an electric aircraft, while being regulated by maritime authorities enabling market entry for a fraction of the cost. REGENT has de-risked seaglider technology with a ¼-scale, 400 lb, flying demonstration vehicle and a full-scale wing test section. By 2024, REGENT will fly humans on the first full-scale prototype seaglider. By mid-decade, REGENT’s customers - airlines and ferry companies – will begin commercial seaglider service on the 12-seat initial product. In just two years, REGENT has accumulated $8B in provisional orders (including firm deposits) proving the potential of the $25B+ initial market. REGENT, a team of 40, is led by MIT-trained, ex-Boeing engineers Billy Thalheimer and Mike Klinker. REGENT has raised $50M to date from the likes of Thiel Capital, Founders Fund, Mark Cuban, Y Combinator, and includes strategic investment from Japan Airlines, Hawaiian Airlines and Mesa Airlines.

  • Reviving Mind
    Reviving Mind (w2022)Active • 3 employees • Boston, MA, USA
    Navigating chronic illness is an isolating and lonely process which ultimately reduces medical adherence and adversely impacts outcomes. There are over 100 deadly chronic conditions as 1 out of 2 Americans is currently living with at least 1 chronic condition. The US healthcare system has over $1 trillion dollars in direct costs. Medical adherence rates for therapeutic programs and medicine are only 50% because patients feel lonely, isolated, and unsupported in their chronic illness journey. Reviving Mind is an in-network telehealth provider that improves clinical outcomes and program adherence for the senior medicare and medicare-advantage population that is plagued with loneliness and chronic illness. This is done through a novel and proprietary clinical program and technology platform that integrates virtual, private, curated, and professionally led groups that scale up to 8-patients with individualized and goal oriented lifestyle medicine coaching that is automated but managed by a licensed provider. Scaling rapidly across the United States.

  • Firecrawl

1. Previously, we built Mendable, one of the first commercially available “chat with your data” applications. We sold to companies like MongoDB, Coinbase, Snapchat, and more. To do this, we spent a surprising amount of time building reliable infrastructure for getting clean data from the web. When we started to see our founding friends rebuilding the same thing, we thought we might be on to something. We see Firecrawl evolving into the easiest way for humans or AIs to collect data on the web. Imagine a magical interface instantly gathering data from any format, anywhere, with no code required.
