Background

Jay Liebowitz is a Los Angeles–based credit and principal-investing executive with more than twenty years of experience in leveraged finance, distressed debt, and mezzanine investing. He is a Managing Director and Co-Founder of Centerstone Capital, a merchant bank operating out of Century City (1801 Century Park East, Los Angeles) and New York (500 Fifth Avenue). At Centerstone he leads the firm's Debt Advisory and Principal Investing efforts, working across the firm's M&A advisory, private placements, secondary transactions, and IPO advisory platform.

Before co-founding Centerstone, Liebowitz spent roughly a decade (September 2013–December 2023) as a Managing Director at Post Advisory Group, LLC, a Los Angeles credit manager specializing in high-yield and other non-investment-grade credit strategies — the firm associated with his [hidden] email. He joined Post from GSO Capital Partners (Blackstone's credit arm, later Blackstone Credit), where he was a principal focused on high-yield, distressed, and mezzanine investments across a range of industries.

Earlier in his career, Liebowitz was an associate at Black Canyon, an affiliate of Canyon Capital Advisors, where he analyzed and recommended private debt and equity investments. He began his career as a financial analyst at Credit Suisse First Boston, concentrating on leveraged finance and restructuring transactions.

Liebowitz graduated summa cum laude from the Wharton School of the University of Pennsylvania with a Bachelor of Science in Economics. Outside of investing, he serves on the board of Access Youth Academy, a non-profit focused on urban youth development.

Investment Thesis & Focus

  • Operates as a merchant banker and credit investor, not an early-stage equity angel — activity spans M&A advisory, debt advisory, private placements, secondary transactions, IPO advisory, and direct principal investments.
  • Deploys and advises on capital in established companies, with Centerstone's typical transactions ranging from $100M to $2B in enterprise value.
  • Sector concentration in Consumer, Business & Consumer Services, Healthcare, Media/Sports/Entertainment, and Technology.
  • Deep expertise in high-yield, distressed, and mezzanine credit built over careers at GSO/Blackstone Credit, Post Advisory Group, Canyon Capital, and Credit Suisse First Boston.
  • Centerstone frames its value around "robust global investor relationships," "senior attention on all transactions," and deep domain knowledge — implying a relationship-driven, senior-led deal process rather than high-volume small-check investing.

Notable Investments

  • No verifiable record of individual angel or seed-stage startup investments could be found; his work is institutional (fund- and transaction-level credit and principal investing at GSO/Blackstone Credit, Post Advisory Group, and now Centerstone Capital), so specific named early-stage portfolio companies are not publicly attributable to him.
  • At GSO Capital Partners / Blackstone Credit, he worked on high-yield, distressed, and mezzanine positions across multiple industries (specific deals not individually disclosed publicly).
  • At Post Advisory Group (2013–2023), he was a senior member of a credit-focused asset manager investing across non-investment-grade corporate credit.
