FoundrAI

An AI co-founder that turns a raw idea into a validated startup blueprint

Persona and jobs-to-be-done generation

Produces editable customer personas and JTBD statements so positioning and messaging target the highest-value users rather than everyone.

TAM, SAM and SOM estimation

Generates market-size estimates from industry and trend context, saving founders from assembling spreadsheets and survey data by hand.

GTM and competitor analysis

Recommends go-to-market channels and produces SWOT and competitor breakdowns to sharpen positioning and differentiation.
