What percentage of transaction financing now occurs outside the regulated banking system compared to 24 years ago?
The reversal is complete: when Weisburd started Monaro Capital in 2001, 90% of transaction financing flowed through regulated banks and just 10% through non-bank sources. Today, that ratio has inverted entirely—90% of transaction and buyout financing now occurs outside the banking system through private credit managers, leaving only 10% within regulated banks.
This seismic shift reflects a fundamental change in how the middle market finances growth and acquisitions. Banks, constrained by post-crisis regulations and capital requirements, became less flexible in structuring deals. Non-bank private credit firms filled the gap, offering customized solutions that the regulated banking system could no longer provide.
When Weisburd was practicing M&A and bank financing law before 2001, the non-bank landscape barely existed. Only two firms—GE Capital and Heller Financial—operated outside banking regulations, and they focused exclusively on large, trophy deals. The lower middle market had no alternative to inflexible bank lending, making it ripe for disruption. Weisburd saw the opportunity to apply legal and banking expertise to serve smaller companies with creative, tailored financing structures.
The market has validated this vision. As detailed in this episode, the private credit market today stands at $2 trillion and is projected to reach $5 trillion within five years. Over 550 private credit firms now exist, though many are newcomers—40% were founded within the last ten years, and only four have operated for more than two decades.
David Weisburd — Founder and CEO of Monaro Capital, which manages $24 billion in assets and deploys $10 billion annually. Weisburd holds degrees in accounting, finance, and law, and spent 14 years practicing M&A and bank financing law for private equity transactions before founding Monaro Capital in 2001 to serve the lower middle market with creative, flexible transaction financing.
The structural causes run deeper than mere market appetite. As Weisburd explains in the full podcast, regulatory frameworks introduced after the 2008 financial crisis imposed stringent capital requirements on banks for leveraged buyout loans, while asset-backed securitization and non-bank lending faced fewer restrictions. Banks retreated from the middle market; private credit advanced into it.
This transition matters because the lower middle market—roughly 200,000 companies in the U.S.—represents 50% of American workforce employment and one-third of U.S. GDP. Without flexible financing options, these companies would struggle to grow or consolidate. Private credit filled that void, enabling transactions that the traditional banking system had abandoned.

How did regulatory changes after the 2008 financial crisis reshape the private credit market?
After the financial crisis, regulators imposed high capital requirements on banks for leveraged buyout loans but low requirements for asset-backed financing, creating space for non-bank private credit firms to grow and serve markets banks had exited.
What market conditions and regulatory gaps inspired the creation of a non-bank private credit firm in the early 2000s?
Weisburd observed that banks were inflexible due to regulations, while the only non-banks operating at the time—GE Capital and Heller Financial—could structure deals creatively and customize transactions, but focused solely on large deals, leaving the lower middle market underserved.
What common cognitive bias limits venture investors' deal sourcing and reduces returns?
Venture investors have historically relied on their networks to surface opportunities, creating a bias where they miss high-quality outsiders, reducing deal flow and limiting returns across the investment cycle.
