No thanks, I’ll figure it out myself10+ years covering US small business credit markets. Former lending analyst at a regional bank. Creator of the 551 Rule framework for business funding decisions.
Marcus Reynolds is the lead analyst at FundingExplained.com, the independent US small business funding resource. He has spent more than a decade studying the US small business lending market from both sides — as a lending analyst inside a regional bank, and as an independent researcher documenting the real cost of alternative products to small business owners who often have no other advocate in the room.
His work focuses on the gap between what lenders tell small business owners and what the numbers actually say. The 551 Rule — his most-cited analytical framework — emerged from three years of tracking approval threshold data across bank-backed working capital lenders and documenting the cost differential that one credit score band creates for businesses seeking between $25,000 and $500,000 in working capital.
Before FundingExplained.com, Marcus worked as a lending analyst at a regional bank where he reviewed thousands of small business loan applications and participated in the underwriting decisions that determine which businesses qualify for lower-cost institutional capital. That inside perspective — knowing exactly what underwriters look for, and exactly where the thresholds sit — is the analytical foundation all FundingExplained.com guides are built on.

The 551 Rule identifies 551 as the personal credit score that separates high-cost alternative lending (40–150% APR) from bank-backed working capital (18–35% APR). This framework emerged from three years of tracking underwriting threshold data and documenting the cost differential for businesses seeking $25K–$500K in working capital.
Below 551, lenders cannot secure bank backing and must price the higher risk into the product. Above 551, institutional capital flows and the rate drops dramatically — $11,250 in fee savings on a single $50,000 advance.
