Tips for Segmenting Companies by Business Model, Not Industry

Does anyone have experience looking for company segments more based on business model or other segment rather than industry when building a company list? For example, when looking for online marketplaces, you get a lot more results when you remove all other filters and just go by description. Does anyone else have tips for doing this without building a huge list, then using a Claygent to research their website and spending loads of credits? Other examples of segments I want to build: FinTech, B2B SaaS, CleanTech etc.
