Why now

The shift towards 'agentic' AI allows models to actively execute tasks rather than just acting as reactive text generators.

Market gap

LLMs are currently reactive 'gaslighting engines' requiring constant manual prompting. Founders need a proactive, aligned agent that executes tasks autonomously based on deeply learned context.

Business fit

Type: AI Agent / SaaS
Target: Solo founders, SaaS founders, YC founders.
Revenue: $50-$100/mo per user initially; potentially millions ARR at scale.
