Sell-side advisor to Castillo Facility Services, 2025You built it over decades. Sell it like it matters.
We are a San Diego sell-side M&A firm for owners of established, profitable businesses outside tech. We plan the exit, find the right buyer, and stay with you to the closing table.
Most of our clients started their company with a truck, a loan, or a single customer. Selling it is the largest financial decision they will make.
We represent founder-owned and family-owned companies with $2 million to $40 million in revenue: service companies, construction trades, manufacturers, distributors, and healthcare service practices. We run a confidential, competitive process, and a managing director leads every engagement from the first valuation to the wire.

Honest numbers first
We tell you what your business is worth today and what would raise its value, even when the honest answer is to wait two years.
A competitive buyer market
Every engagement goes to a tailored list of strategic buyers, private equity groups, family offices, and qualified individuals. Competition sets the price.
Senior attention, start to finish
A managing director leads your sale. You never get handed to a junior team after you sign.
We know businesses outside tech
We know how buyers value route density, backlog, recurring service contracts, and skilled crews, and how to show it.
"Alex told us our cleaning company was worth more than we thought, and then proved it. We had four offers and closed 30% above our first number."
