By Brett Kaufman. 8 years using relationships to build sales pipelines, from political fundraising to a 7 figure business to running matchmaking for two communities. Over 1,000 introductions facilitated.

The best conference sponsors relationships M&A buyers can build are with the lenders, accounting firms, law firms and advisors who pay to be in the room. They see dozens of deals a year, they want to meet you, and most buyers walk straight past their booths on the way to the bankers.

Picture this. Day two of a deal conference. Sessions are running, the hallway is empty, and a quality of earnings partner is standing at her booth with a bowl of mints and nobody to talk to. She worked on 30 transactions last year. Four of them died in diligence, and the sellers still want out.

You walked past her to stand in line for a banker who already had 40 meetings booked.

Why are conference sponsors a deal source?

Because a sponsor’s whole business is transactions. Service providers sit beside deals before, during and after they close. They hear about the owner getting ready, the buyer who lost financing and the deal that fell apart in month three.

The sponsor list tells you exactly who is there. At DealMAX, ACG’s middle market conference, set for May 3 to 5, 2027 in Las Vegas with more than 3,500 attendees, the 2026 sponsor list included Datasite, Forvis Mazars, S&P Global Market Intelligence, Crowe, Plante Moran, Baker Tilly, JPMorgan, PwC, Clifford Chance and Troutman. That is accounting, banking, data and law in one list.

Smaller rooms work the same way. The AM&AA 2027 Winter Conference, January 28 to 29, 2027 in Fort Lauderdale, lists sponsors including Banesco USA, CPA Deal Desk, Doeren Mayhew, TaxConnex, Holland & Knight and Raymond James Financial. The Exit Planning Summit, May 2 to 4, 2027 in San Diego, lists more than 80 sponsors, and those are firms serving business owners years before a sale.

ACG’s own sponsor page pitches sponsorship as a way to get in front of key decision makers. Sponsors paid for conversations. Give them one.

Which conference sponsors relationships M&A buyers should build first?

Start with the sponsors closest to a deal before it goes to market. Here is my map. It is a framework, not data.

Sponsor type	What they see	What they want from you	Your ask
Accounting and quality of earnings firms	Sell side readiness work, deals that died in diligence	Your QoE and tax work when you have a deal	“When a deal falls apart and the seller still wants out, I would love a call.”
Lenders, banks and SBA lenders	Which buyers are financed, deals that lost their buyer	Your loan	“Who in my niche are you seeing come to market this year?”
Deal law firms	Dead deals, second bidders, owners doing succession work	Your deal counsel engagement	“If a client wants a quiet buyer conversation, here is my box.”
Exit planners and wealth managers	Owners three to five years before a sale	A buyer who treats their client well	“Who on your list is planning but not ready?”
Investment banks and broker dealers	Sell side mandates	Buyers who close	“Put me on your buyer list for these sectors.”
Data rooms and data providers	Which advisors are active, market trends	Your subscription	“Which advisors in my niche are busiest right now?”

The top four rows hear early. The banks hear at mandate. The data sponsors give you intelligence, not introductions. All six are worth a follow up.

How do you work sponsor booths at a conference?

Here is how I would run it.

1. Before the event: pull the sponsor list. It is usually on the event site. Pick eight sponsors that work in your size range and sector.
2. Look up one person per sponsor. A partner or market leader, not the marketing coordinator. Check what deals or clients they have posted about.
3. Visit during sessions. The booths are quiet when the rooms are full. Sponsors have time, and you get 15 minutes instead of two.
4. Say exactly what you buy. One sentence: sector, size, region, what you keep. They can hold that against every client in their head.
5. Ask about their year. What they are seeing, which deals stalled, what owners are asking them. Then listen.
6. Capture before you walk away. Name, firm, one detail, one deal pattern they mentioned.

For booking the bigger meetings around the event, see how to book meetings at a deal conference.

What do sponsors want back?

Work and referrals. That is the deal. You will need a lender, a quality of earnings firm and deal counsel for your next acquisition anyway. The sponsors who help you find it should get first look at that work.

Give first. Introduce the lender to an operator you know who needs financing. Send the accounting partner a seller you passed on who needs sell side prep. Tell the law firm about the searcher who just signed an LOI. One useful introduction after the show is worth more than a booth conversation.

If a sponsor offers a referral fee or you are thinking of paying one, ask your deal counsel first. Lenders, lawyers and accountants each work under their own professional rules, and the introduction finder’s fee guide covers what to check.

What happens in the 48 hours and 12 months after?

The first 48 hours turn a booth chat into a relationship. Text each of your eight within two days. Two illustrative texts, under 40 words each:

“Good talking at your booth during the lender panel. Your point about deals dying in month three stuck with me. If one of those sellers still wants a buyer, I would love to hear about it.”

“Thanks for the time Tuesday. I mentioned an operator who needs a line of credit for an add on. Want an intro this week?”

Then the long game. Touch each sponsor every 60 days with a real reason: their firm’s news, a post, a deal you passed on, an intro you can make. When you close, send them the work. Sponsors remember who sent business.

The same logic runs through every service provider around a deal. See industry consultants and former owners as a deal source and how to find owner direct business deals in your network. The full map is at deal flow for business buyers.

Where does this break?

At month two. You met eight sponsors, texted five, and then three other conferences and a live deal took over. The quality of earnings partner gets a call from a seller whose buyer walked, and she mentions the buyer who sent her a client last month. You never sent one.

That is the job I built FRONT OF MIND for. At the booth, say a name and a sentence out loud, snap the business card or badge, or take a selfie together, and it is filed under the event. After the show it opens on your 10 minutes for today. Each person has a one line reason why today: they posted, their firm was in the news, you met at the event 40 days ago and never followed up, or they are going cold. Intros to make this week show up with dated proof on both sides, so the lender and the operator you promised to connect do not slip. Every draft is a text style message, 40 words max. Nothing sends without your tap, and it learns from your edits.
