I wanted to see
what the list was built on.
FirmTrove was built by Menno Gottmer and is a Gottmer Agency brand. This page explains why he builds the company database and how FlintLead uses it.
Menno Gottmer Founder
I founded FlintLead and FirmTrove and I am COO of Adaptive Teams and SellerPlex. I build systems that make execution inspectable. FirmTrove grew out of FlintLead’s prospecting practice and now maintains the company database itself: the same question, where does this fact come from, deserved its own product.

Used in FlintLead’s prospecting.
FirmTrove builds the database. FlintLead uses it.
FirmTrove collects and enriches the company data. FlintLead reads the same records through FirmTrove's internal API to run done-for-you cold outreach for clients. That is where FirmTrove started, around one question: where did this fact come from, and may I use it?
Both are Gottmer Agency brands. Customer data and consents stay separate per brand.
