Yard Stick
|
Yard Stick measures soil carbon. Scientists and farmers alike know that climate-friendly agricultural practices have the potential to remove atmospheric CO2 at gigaton/year scale. When these practices are adopted, more carbon is stored in soils, improving soil health and fighting climate change. But significant measurement challenges have heldsoil carbon efforts back - until now.By reducing the cost of soil carbon measurement by 90%+, Yard Stick will dramatically expand the opportunities for evidence-based regenerative practices to simultaneously improve ecosystem health, increase farmer income, and combat climate change. | $600K / Pre-Seed / Feb 24, 2021 | |
Medsix
|
Patients who experience complex high risk surgery or are expected to heal slowly are often managed with a wound drain. Current drain output monitoring practices are manual - nurses (in the hospital) and patients (at home) eyeball the color and volume. Inaccurate data means drains are usually installed longer than necessary and nurses and patientsmiss early onset of complications (infection, leaks, excessive bleeding, blockages). This results in longer lengths of stay and increased readmission rates.Medsix plans to sell a disposable sensor with predictive analytics that can be attached to any wound drain to automate monitoring. This will address the needs of patients (detect complications earlier; remove drains earlier; reduce overall recovery time), providers (improved clinical workflow and decision making; creating a standard for wound drain output) and payers (reduce length of stay; reduce readmission rates; increase reimbursements). | Pre-Seed / Dec 20, 2019 | |
