Thinkfill AI is a due diligence service for AI purchases. It rates real AI vendors on capability, financials, references, team and price, then recommends which one to pick for your project, so you avoid months of research and an expensive wrong choice. You describe a use case, for example support automation with SOC 2 compliance, a budget under $2k per month and a 50-seat team, and a decision scan matches vendors and shows scores side by side. You can use the self-serve tool or have the team run the whole evaluation with you.
It is written for the person who has to make the call. Founders and operators who want AI to take work off their plate get a starting point without testing tools for months. CTOs and engineering leaders can hand off vendor diligence on capability, security and how a product holds up at scale, so engineers keep shipping. Product leaders adding an AI feature get ratings for the vendor they will build on. The research behind it draws on conversations with about 190 people about their fears and nearly 900 about what they want AI to do.
Scenarios include choosing a customer support automation vendor, selecting a platform for marketing content, comparing research and analysis tools, or picking an API for a coding or app project. Workflow and task automation is the largest request category, followed by marketing and content creation, research and analysis, coding and apps, and sales and lead generation. The aim is to catch poor fit, hype and cost surprises before money is committed, with a recommended vendor named for your needs.
