Signature Bank (Chicago) offers relationship-based commercial banking services, focusing on closely held companies and retail banking. Services include commercial lending, wealth management, and retail banking capabilities[2][4]. The target audience is small to medium-sized businesses and individuals seeking personalized banking experiences. The unique selling proposition is its emphasis on creating a positive workplace for employees, which translates into excellent customer service and a strong team-based approach to banking[2]. Note: This is distinct from the New York-based Signature Bank, which was closed in March 2023[3][5].
