In my experience, start-ups play fast and loose with all sorts of things like security, data integrity etc. It's how they can quickly build a service an offer it to larger companies who would never get it done due to internal management inertia, politics, architecture reviews, project management, processes, audits, controls and regulations. However, it shouldn't be "that" bad. For example, I worked at a start-up that successfully made it to $8+b valuation, and they had tons of extremely scary shit. But generally when someone found a critical issue, everybody sighed, rolled up their sleeves and fixed it. Because a security breach, data leakage or data loss that is caused by such negligence is a company extinction event for a start-up. These guys are playing Russian Roulette. Get out before the inevitable occurs.
