Proof of Usefulness Score
Category Standard

Coast (CoastApp) demonstrates significant real-world utility as a communication and operations platform for deskless workforces, with verifiable traction of over 100,000 teams and high app store ratings (4.8 stars). However, the submission quality is low, featuring hyperbolic claims ('most people have used my product') and discrepancies in team size likely due to conflation with CoastPay (a separate Series B fleet payments company). Despite the lazy data entry, the underlying business fundamentals and verified market presence justify a high score, situated in the 'Much larger scale' bracket.

Description
We help small businesses succeed by enabling their team members to communicate quickly and flexibly. Whether it’s sending a message, completing a checklist, tracking deliveries, closing maintenance issues, or getting a shift covered, Coast gives business owners and managers time back. Staff find our app so intuitive that they can use it without any training and can participate from Android, iOS, desktop, tablet, or even a flip phone using SMS.\n\nSMBs make up 1/3 of the GDP but fail at a rate of 50% within 5 years. By supporting their operations, we can change this failure rate and the GDP!\n\nCoast is backed by VCs behind companies like Slack, Evernote, Lyft, Gusto, and Zoom. Our founders previously built a startup in SMB market that was acquired.
