Proprietary deal sourcing is the work of finding acquisition targets yourself, or through a firm working for you, instead of waiting for a business to be listed or brought to market by a broker. The buyer reaches the owner directly. If the owner is open to a sale, the conversation starts with one buyer, not an auction.
"Proprietary" refers to how the deal was found, not to who owns it. A proprietary deal is one the buyer originated: the owner wasn't marketing the business, and no intermediary was running a sale process when the buyer made contact.
What it involves
- A buy box. Written criteria for industry, geography, size and owner situation. Without one there is nothing to source against.
- A target list. Businesses that fit the buy box, built from public and commercial data, then checked by hand.
- Outreach. Personal, researched messages to each owner, by email, letter, phone or LinkedIn. Owners can tell a message written about their business from a template sent to thousands.
- Cultivation. An owner who replies often isn't ready to sell right away. Staying in touch over months is how a "not now" turns into a conversation later.
- Qualification. Early calls to understand the owner's goals, timing, rough financials and fit before the buyer spends serious time.
Why buyers use it
The main reason is competition. A listed or brokered business attracts many buyers, and the process is designed to push the price up. A buyer who reaches an owner first can learn about the business, build trust and talk terms without a deadline set by someone else. It also widens the pool to owners who might sell on the right terms but have no plan to call a broker.
What it doesn't guarantee
Proprietary sourcing finds conversations, not closed deals. Owners change their minds, financials don't hold up in diligence, and timing slips. The work produces a pipeline of owners at different stages, and a buyer still needs capital, advisors and diligence to get any one of them to close.
Who does it
Some buyers run it themselves. Others hire an analyst, use a sourcing firm, or combine both. Aligned Profit's process is one example: we build the list, write to each owner and hand the buyer a qualified conversation. Read how off-market acquisition sourcing works for the steps in more detail.
Common questions
Is proprietary deal sourcing the same as off-market deal sourcing?
They are used almost interchangeably. "Off-market" describes the business: it isn't listed or in a broker's process. "Proprietary" describes the buyer's position: they originated the deal themselves.
Does proprietary sourcing mean the seller never talks to anyone else?
No. The buyer is first in the conversation, but the owner is free to talk to others, hire a broker or run a process. Being first and building trust early is the advantage, not exclusivity.
Is a deal sourcing firm the same as a business broker?
No. A broker usually represents the seller and is paid when the business sells. A buy-side sourcing firm works for the buyer and finds owners who match that buyer's criteria. See brokered versus proprietary deal sourcing.
