Hi James,

I've just finished a report about the salaries of software engineers in LATM.

Would you like to have a look?

The talent pool of software engineers is super strong - Google (who we have

worked with) have their hubs here.

If yes, just let me know and I'll send over the report.

Multi-channel orchestration with perfect timing

Most AI sales tech is just glorified templating.

Legacy platforms force AI onto systems never built to handle or support it.

"AI Platforms" use primitive prompt stuffing, not true AI intelligence.

"AI tools" use primitive prompt stuffing, not true AI intelligence.

Data focused tools apply basic ‘if-then’ logic, not contextual understanding.
