Internal scripts and one-off automation, throwaway prototypes to test an idea with a few users, personal projects with no uptime or security requirements, and quick proof-of-concepts for investor pitches. If nothing breaks when the output is wrong, and nobody but you depends on it working tomorrow, AI tools alone can get you there fast.
Anything handling customer data or payments, products with paying customers who expect uptime, codebases more than one person will touch, and systems that need to scale, integrate with other services, or pass a security review. The risk with AI-only development isn't that the code doesn't run — it's that it runs until it doesn't, usually at the worst possible time, with no one who understands the system well enough to fix it fast.
Most growing companies land here: a developer (in-house or contracted) who uses Cursor or Copilot as a force multiplier. You get the speed of AI-assisted development with someone who can catch the architectural mistakes, security holes, and edge cases AI tools routinely miss — and who can actually debug it when something goes wrong.
Need vetted developers who already use AI tools well? Greatex Services places pre-vetted contract engineers across the US, UK, UAE, and ANZ — onboarded in days, not weeks.
