As answered by people managing Eloquent JavaScript and Photon Research.

Speed and affordability. Traditional research firms charge thousands and take weeks. ChatGPT gives unstructured, unsourced answers. We deliver professional reports in 6 hours from $29, with verified sources and a format you can share with investors or your team.
Photon Research's answer:
SaaS founders validating ideas, indie hackers scoping markets, agencies doing competitive analysis for clients, and investors doing due diligence. Anyone who needs real data to make confident decisions.
