PEDRA Technology
PEDRA Technology is a Singapore-based medical device company that built the PEDRA Xauron Perfusion System, the first device to deliver real-time, quantitative measurement of deep-tissue blood perfusion in the foot during vascular procedures. Aimed at physicians treating peripheral arterial disease (PAD) and critical limb threatening ischemia (CLTI), the laser-based, non-invasive system gives interventionalists objective feedback in the angio suite - where they have historically relied on subjective interpretation of X-ray images. The company raised a $4.7M Series A in 2020 and won FDA Breakthrough Device Designation in 2021.
Classkick
Classkick is a Chicago-based education technology company that makes a digital formative-assessment platform where teachers watch students work in real time and give instant feedback. Founded by former Teach for America math teacher and ex-Google/YouTube engineer Andrew Rowland, the tool lets teachers build or import interactive assignments, draw directly on each student's canvas, drop reusable feedback stickers, and auto-grade multiple-choice and fill-in-the-blank answers. Students can raise a virtual hand for help - even anonymously - and ask peers. Used by more than 10 million users across all 50 U.S. states and dozens of countries, Classkick's pitch is simple: more tries for kids every day, and less grading busywork for teachers.
Tenor
Tenor is a San Francisco AI platform that helps managers get better at the human part of the job. Through hyper-realistic voice AI role-play simulations trained on a company's own leadership approach, managers rehearse high-stakes conversations - performance reviews, layoffs, conflict, feedback - in a safe space and get instant, coaching-style feedback. Founded in 2023 by former Workday leaders Charlie Stigler and James Cross, Tenor raised a $5.4M seed round led by Base10 Partners in December 2024.
FeedbackNow
FeedbackNow is a New York-based real-time customer experience company best known for the Smiley Box - the push-button terminals that ask travelers, patients and shoppers how their visit went and route that sentiment to operations teams within minutes. Founded in Switzerland in 2012, acquired by Forrester in 2018, and spun back out as an independent, venture-backed company in 2024, it pairs physical feedback devices and environmental sensors with AI analytics to help airports, hospitals and retailers fix problems before they show up in a survey.
