What have been the biggest mistakes and how did you address them?

An earlier version of the product did not have the full set of firewalls and decoupled monitoring systems in place. We addressed it not just by patching the specific problem but by building an entirely different system to systematically prevent that class of problems going forward. My general philosophy is never be reactive. Always be proactive about what new surface areas are being introduced and what new risks might come with them. That is why we ran the invite only early access program from the start. It is not meant to be exclusive. It is meant to let us scale responsibly so we do not wake up one morning with ten times the users and 80 percent of them unable to use the product because we did not have the compute to support them.
