Gregg Jaclin

Gregg Jaclin is Managing Director of Exchange Listing LLC, the capital markets advisory firm he now owns outright after acquiring his co-founder's stake. He is also the founder of JRB Consulting LLC, a Princeton, New Jersey advisory practice established in 2017. Across more than 30 years in capital markets — 25 of them as a securities attorney before he moved to the advisory side — Jaclin has built one of the more active listing practices in the emerging growth and micro-cap market.

His transaction record covers the full range of routes onto a senior U.S. exchange: traditional IPOs, uplistings from the OTC and from foreign markets, SPAC mergers, Nasdaq mergers, and direct listings. Sixteen documented engagements span Nasdaq Capital Market, NYSE American, and Cboe — including the first-ever U.S. initial public offering completed on Cboe — with offerings ranging from $5.0 million to $50.1 million and issuers domiciled across five countries. Named transactions include La Rosa Realty, Neuraxis, Inspire Veterinary Partners, SurgePays, HeartBeam, GreenBox POS, Tenon Medical, Cosmos Holdings, VCI Global, Treasure Global, and Siyata Mobile, spanning healthcare, fintech, real estate, technology, e-commerce, and pharmaceuticals.

The work itself is more specific than "IPO advisory" suggests. Investment banks raise the capital, securities counsel drafts the registration statement, and auditors handle the numbers; Jaclin's practice occupies the gap in between. That means introducing, negotiating, and managing the underwriter relationship — recorded in thirteen of his sixteen case studies — alongside board and governance build-out, integration of Nasdaq, SEC, and exchange compliance requirements, arranging bridge financing ahead of a listing, and staying engaged in the aftermarket once the bell has rung.

As Nasdaq and the NYSE have raised minimum valuation and float thresholds and expanded their discretion to deny listings on qualitative grounds, Jaclin has become equally known for telling companies when they are not ready — and steering them toward a private raise, a crowdfunding round, or a SPAC merger rather than a transaction that will not hold up. With much of his fee back-ended into post-listing equity, his interests sit with the company's performance after the offering, not the closing.

Jaclin has also developed an extensive network across Southeast Asia — Singapore, Malaysia, Indonesia, and Vietnam — advising regional companies seeking the valuation and liquidity of a U.S. senior exchange listing. He holds a B.A. from the University of Maryland, College Park and a J.D. from the Benjamin N. Cardozo School of Law.
