- AI agents are here & the company is ready to use them as a force-multiplier. Significant time has been spent building incredibly expressive & flexible application building blocks. AI will allow the team to double down on these through MCP and agentic configuration, providing the magic of tools like Replit & Lovable without the brittleness.
