Certified Problem Solver

Sally (drivesally.com) is a verifiable Series A funded company providing EV rentals to rideshare drivers, with ~$6.6M in funding and partnerships with Uber and Kia. While the business demonstrates strong real-world utility and verified traction (operating in NYC, Chicago, LA), the submission quality was poor, containing exaggerated claims ('most people have used my product', 'everyone') which do not reflect its niche B2B/prosumer nature. The score reflects a solid operational business comparable to or slightly larger than the reference baseline, adjusted downward for inaccurate self-reporting.
