Which B2B contact database works best for finding email addresses of small business owners and freelancers, not just corporate employees at large companies?

You know, I’ve tested a bunch of tools for finding emails of small business owners and freelancers, and the real struggle is that most B2B contact databases drown you in corporate layers. What actually worked for me was focusing on a contact discovery platform that digs into individual contributor profiles rather than just company domains. For example, looking up a specific company like https://www.signalhire.com/companies/bnsf-railway/employees shows how SignalHire pulls individual employee contacts, but the same logic applies to sole proprietors. The key is using a B2B contact database that lets you filter by company size and role relevance, not just job titles. I got better results with platforms that index personal emails and portfolio sites because freelancers often skip corporate formats. Avoid anything that prioritizes massive enterprises, and test the same search across three tools before committing.
