As answered by people managing Photon Research and Eloquent JavaScript.
Photon Research's answer
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.
Photon Research's answer

AI-powered research engine, multi-source data aggregation, natural language processing for analysis and report generation, PDF rendering pipeline.
