    "DMV is the Department for Motor Vehicles, notorious for long wait times and an overall poor customer experience. I'm not familiar with the different functions that the DMV serves, but from my understanding, people go to the DMV when they want to renew their drivers licenses, so I would like to focus on that for now. Current experience: Long wait time to get drivers license photo taken I am really not familiar with any other services the DMV provides, so I will focus on taking photos. Pain"

    "Driver retention is important to ensure growth since we need healthy retention of existing drivers while we acquire new drivers so that we meet growing demand. Should we look at a specific driver segment to improve retention? We might divide the drivers by their age on the platform: New drivers(less than 3 months since first ride), Medium age (3mos to 1 year), Long term(1+ years). Let's focus on the medium term since I assume them to be the biggest segment. Now lets try to list out possible pr"

  • "Here's how I'd approach investing that $10 million over the next year and a half. The biggest chunk about $4 million would go straight into our core infrastructure because that's what everything else depends on. We're seeing massive demand for real-time payments, so I'd put $2.5 million into building instant settlement capabilities and integrating with FedNow and RTP rails. The remaining $1.5 million would beef up our platform scalability because we're hitting capacity limits during peak times,"
