Carroll Family Holdings


Our best projects involve someone else.
Below are the collected groups that we are involved with:

Letter Tech

Working to disrupt the banking industry is a tough challenge, but Andrew is happy to tackle it with an amazing team. 

Currently Andrew's main focus - he operates as the CFO of the company and is working to bring together banking, a robo-advisor, a digital family office and a marketplace for private investments. 

All of which can be managed from a single app designed for HNWIs. 


Collective (formerly Hyke)

As the founding CPA and Advisor - Andrew is helping Collective in building a turn-key solution to legal and accounting problems for freelancers. You don’t need an army of accountants and lawyers to go it on your own! Joy was instrumental in building their first core systems and Andrew still operates as the Head of Tax and as a Strategic Advisor. 

Kingstone Family Enterprises

Andrew is the founder and former advisor to the Family Enterprise Division of Kingstone Financial. We provide accounting, consulting, and CFO services to Ultra-high net worth families.


Currently in pre-launch, we're developing a "machine human" interface to help small business owners do sophisticated ratio analysis and problem solving on their businesses using KPIs and Core Metrics. 

Kingstone Financial

Andrew serves as a strategic advisor to Kingstone Financial, which provides financial services including investing, real estate, insurance and business advisory services to ultra-high net worth individuals. 

Past Ventures

Northstar Money

I was honored to serve as the “advisor in residence” for a time personal financial start-up Northstar.

Advisor & Founder Titan Angels, Angel Investment Fund

Andrew was part of the founding board of the Titan Angels Angel Investment Fund.


Andrew and our good friend Brett Kelly had a weekly podcast on the Spec.FM network where we talk about the trials and tribulations of being an independent worker.
