Why choose Castor Advisory

Three fundamental differences that matter for your exit.

We Think Like Buyers

After years evaluating acquisitions, we know exactly what makes buyers lean in — and what makes them walk. Your business gets positioned to command the highest price before a single buyer sees it.

One Client at a Time

Michael Comstock leads every engagement personally. No hand-offs to junior analysts. No assembly line. Your exit gets the focus it deserves.

Sellers Only. Ever.

We built our playbook on the buy side — evaluating hundreds of deals, structuring offers, finding weaknesses in seller positions. Now that experience works exclusively for owners. No buy-side engagements. No conflicts. Just a team that knows exactly how the other side thinks.

Every founder's exit looks different

Whether it's a strategic sale, private equity, or a merger — we help you pick the path that fits. Learn more about our process.

"I almost sold to the first buyer who called. Michael showed me why that would have left seven figures on the table."

— Founder, Technology Services Company

"Most advisors told me what I wanted to hear. Castor told me what I needed to hear — and the outcome was better than I imagined."

— Owner, Business Services Firm

"The personal attention and focus made this feel completely different from the 'transactional' experience we expected. This was our life's work, and it was treated that way."
