These brilliant companies are finding solutions that move communities forward.

1. StormSensor‘s platform monitors stormwater in real time using waterproof hardware and cloud-based software, helping to prevent problems such as water contamination in urban areas.

2. Thrive Market is a membership-based e-commerce site that sells (and delivers) organic groceries at up to 50 percent off retail, making healthy food accessible to low-income families.

3. Watsi is YCombinator’s first nonprofit, and crowdfunds medical treatment for folks in need around the world; 100 percent of donations go to patient care.

4. Omaze offers anyone the chance to win an out-of-this-world experience for a flat $10 donation. The company is building a self-serve platform to help schools and organizations launch their own campaigns.

5. News Deeply is a single-subject news model that deep-dives into topics like Syria, Ebola and refugees. Its sites’ audiences are packed with academics and humanitarians, impacting policy and action.

8. Nascent Object’s latest product, Droppler, is a tiny device that tracks a home’s water usage simply by listening to running water, and lights up to communicate waste — which can help cut consumption by 30 percent.
