How does GCS Differ?

We differentiate ourselves by catering specifically to independent investment professionals who focus on private securities. We provide you increased business flexibility, operational leverage, and the ability to lead or participate in a wide range of transactions that you choose. We help you do the business you want to do in a compliant manner. In other words, we foster the growth of your brand, your deals, and your clients.

Our unique service proposition boils down to three C’s:


Compliance is a two-way street. We are obligated to know, supervise and report on your activities, including the securities you sell, your communications with the public, and the investors with whom you work. Similarly, we know that flexibility and speedy turn-around are the keys to success for your business, and we are dedicated to providing you with the support you need.

  • We provide the compliance platform so you can focus on deals, reduce your risk, and receive commissions on the sale of private securities.
  • Our experienced, non-producing Compliance team is easily accessible to provide you with personal guidance to help your deals be successful.
  • Very few broker dealer firms can boast a clean FINRA record: GCS has maintained a clean record since the firm’s inception in 2000.


  • Our services don’t stop once we have signed off on your deal.   After all, your success is our success!
  • Our dedicated Member Services team initially walks you through onboarding steps and subsequently gives you a primary point of contact for any questions.
  • Our proprietary software platform (OLIVIA) makes documentation of your deals and activities simple and tasks keep you organized.
  • Our Membership Package is one of the most comprehensive benefits packages out there.


We understand that the value you place on your broker-dealer relationship largely depends on your day-to-day experience with the firm. Our representatives are the foundation of our business, and only by working closely with their priorities can we create a truly lasting asset. As a client of GCS, you join a network of like-minded investment professionals, with whom you may choose to share deals, contacts and ideas.

  • GCS is one of the largest boutique private placement broker dealer firms in the country.
  • We encourage collaboration amongst our large network of affiliated brokers through networking happy hours, virtual meetings and collaborative functions in OLIVIA.
  • Our brokers are welcome to engage in co-marketing agreements with other GCS reps or outside broker dealer firms to create selling groups.
