About Dan

Dan Belliveau

From the trading desk to building digital products.

As CEO of Vaulted Holdings LLC, I bring business strategy and software development together. I take digital ideas from concept through launch, designing user experiences, building applications, and developing the infrastructure behind them, including user accounts, databases, payments, analytics, and automation.

Before that, I spent more than 17 years in Fidelity Investments’ active trading segment in Boston, Massachusetts, and Merrimack, New Hampshire. My career progressed from customer service for active traders to trading platform product development and a senior role on the Active Trader Desk. I worked with complex options traders, reconciled margin accounts, approved trading activity for high net worth clients, and supervised trading risk. I also oversaw and coached trading representatives, reviewed client calls, and audited departmental activity. In product development, I wrote specifications for platform components and coordinated teams to bring trading platform improvements into production.

My experience also spans general management in the food and beverage industry, installation of smart home and IoT technology, and residential real estate. Those roles added practical experience in running a business, troubleshooting technology, and helping people navigate significant decisions.

I maintain my Florida real estate license and now work on a referral basis, connecting buyers and sellers with agents worldwide. If you’re considering buying or selling a home, speak with me before choosing an agent or taking your first steps. I can help you find the right connection.

My trading background also informs my technical work. I’ve developed automated trading scripts involving live market data, order execution, position reconciliation, and safeguards such as loss limits and restart protection. My experience also includes blockchain technology and creating and releasing my own altcoins.
