Zak Grotenstein

Publisher of Lender List and an operator in commercial finance technology, lender routing, underwriting workflows, and MCA data operations.

Editorial role

Zak develops Lender List’s criteria taxonomy, tool methodology, source standards, and correction process. Guides distinguish sourced lender policy from general industry practice and calculation methodology.

Review standard

Financial calculations are tested against explicit formulas. Lender-specific claims require a dated source or verified lender-domain submission. Unknowns are not filled with assumptions.
