Renowned investment banker Frank Quattrone is coming back to the business with a tech-focused merchant banking boutique.

Quattrone announced today that he and some former colleagues are launching a new venture called Qatalyst Group, a merchant banking boutique, headquartered in San Francisco. Qatalyst Partners, its investment banking business, will provide merger & acquisition and corporate finance advice to technology companies. Qatalyst Capital Partners will make selective principal investments, typically alongside leading venture capital and private equity firms.

Quattrone came to fame when he was with Credit Suisse First Boston, after he was convicted of obstructing an investigation into IPO allocation practices at the firm. That conviction was later overturned on appeal.

Qatalyst’s other initial founders include Jonathan Turner, former global head of Credit Suisse’s Internet group; Adrian Dollard, formerly general counsel of Credit Suisse’s technology group; and Neil Chalasani, most recently a vice president with Evercore’s Technology, media & telecom group; and will include Brian Slingerland, most recently a vice president with Goldman, Sachs’ technology media & telecom group; and Brian Cayne, most recently an associate at Vista Equity Partners. Qatalyst plans to expand its founding team over the next few months.

Quattrone, Qatalyst’s co-founder and CEO said “We will serve our clients as a catalyst for positive change by helping them navigate the forces affecting their industries, analyze the implications for them and their competitors, and develop and execute strategies to maximize long-term shareholder value. We believe the experience, perspective and judgment at the core of our advice will be of value to our clients, especially during challenging environments such as these.”

Qatalyst Partners has submitted an application for registration as a broker-dealer with the SEC and has applied for membership in FINRA, the securities industry self-regulatory authority. While these applications are pending, the firm will operate as a division of JMP Securities, so that they can begin to advise clients immediately.
