  • Materna Medical

    Led · Series B · Jul 2026

    Materna Medical develops technologies addressing unmet needs in women's pelvic health, with a mission to transform the standard of care in OBGYN. Its first product, Milli, is a vaginal dilator originally launched as a wellness trainer in 2019 and cleared by the FDA in 2023 for over-the-counter sale. Milli outcomes have been studied in a post-market prospective virtual study called POMPOM. Materna's second product, Ellora, is an investigational device intended to reduce pelvic floor muscle injury during vaginal delivery and is being evaluated in the randomized EASE trial across 20 U.S. hospitals. The company recently raised $5 million in a B3 financing to support completion of the EASE trial readout, expand Milli channel access, and prepare Ellora's commercialization and manufacturing. Materna is headquartered in Mountain View, California.

  • Theta Neurotech

    Participated · Seed · Mar 2026

    Theta Neurotech is developing a non-invasive wearable EEG patch aimed at forecasting seizures. The company pivoted from a broader consumer "Fitbit for the brain" concept toward a medical wedge focused on epilepsy after identifying clinical demand and behavioral considerations for EEG wearables. Theta has raised $2 million in pre-seed funding to support device development, machine-learning research, and an exploratory clinical study. Co-founders Truman Pierson and Christopher Fitz lead the company. The market for seizure monitoring includes invasive and non-invasive competitors, but non-invasive seizure forecasting remains early-stage and challenging. Several rivals are running exploratory studies, and none have yet reached patients.

    Champions Round offers short-form "micro fantasy sports" games that can be played daily, weekly, monthly or quarterly, removing the need for season-long commitments.

Champions Round has grown to 10 employees (up from five earlier this year) and plans to hire more engineers to improve the app. It has formed marketing partnerships with athletes including Baron Davis and a co-branding deal with YnG DnA, and it hopes to offer traditional sports betting in coming years while taking a cautious approach to NIL partnerships.
