Since then, Rosenblatt has adapted to changing times and diversified. Today we are:
- The industry’s largest floor broker
- A provider of top-notch agency execution desk services
- The undisputed leader in market-structure analysis
- A source of differentiated equity research on the TMT sector
- An award-winning FinTech and TMT investment banking boutique
But one thing remains the same: our passion for improving the capital markets and an unwavering commitment to a culture of independence, integrity, and intellectual honesty that has guided us from day one.
