Healthcare sell-side mandates: which owners will talk.

Healthcare sell-side mandates are not one market, and the sub-sector a healthcare bank chooses decides how hard every mandate is to win. Across 200,946 acquisition and exit emails to healthcare business owners, health tech owners were open to a conversation at 4.9 per 1,000 emails and medical practice owners at 0.2. Put as a planning number, that is 205 emails for each open owner in health tech and 5,618 in medical practices: the same banker, the same calendar, a 27-fold difference in effort.

The data is ours. DealSource Systems is the deal origination arm of Danish Lead Co and runs sell-side mandate origination for healthcare banks, and the figures come from the healthcare slice of our owner response rates by sector dataset, which covers 16 weeks of real outreach run for private equity buyers and M&A advisors. No client is named and no figure can be traced to one. What this page adds is the healthcare-only cut, two columns that were not in the original table, and what a healthcare investment bank should do with them.

What did we measure in healthcare?

We measured how owners of eight kinds of healthcare business answered outreach that asked whether they would talk about an acquisition, a partnership or an exit. The window ran from 19 June to 11 October 2026, almost entirely to US businesses.

• Emails. 200,946 sent, follow-ups included.
• Open to a conversation. A reply that said the owner was interested or asked for a call. Requests for more information are counted separately, so the figure is deliberately strict. 187 owners qualified.
• Human replies. Every reply except out-of-office notices and messages that could not be classified: 1,139.
• Emails per open owner. Emails sent divided by open owners. This is the number to plan a pipeline with, because it converts a rate into a workload.
• Do-not-contact share. The share of human replies that asked not to be contacted again, which we read as a rough measure of how tired a sub-sector is of being asked.

The full method, the caveats and the other four sectors are in the original research. Every figure below comes from the same dataset.

Which healthcare owners will talk about selling?

Health tech owners were by far the most open, and medical practice owners the least. The spread between the top and the bottom of healthcare is wider than the spread between healthcare and every other sector we measured.

Two things stand out. Health tech and physical therapy are the only healthcare sub-sectors where open owners outnumbered the owners who asked not to be contacted, and health tech's do-not-contact share of 7% is about a third of the healthcare average. At the other end, med spas, imaging and owner-led healthcare businesses combine low response with a high do-not-contact share, which is the signature of a sub-sector that buyers have already been working hard.

How many emails does one healthcare mandate conversation take?

At the healthcare average, a bank needs about 1,075 emails for every owner who agrees to talk. That one number answers most of the planning questions a healthcare M&A advisor asks before starting outbound.

Say a bank wants ten open owner conversations a month, which is roughly the pace at which a small team can qualify and follow up properly. In health tech that is about 2,050 emails a month, comfortably inside what a single well-built sending set-up delivers. In owner-led healthcare businesses it is about 16,800. In medical practices it is about 56,000, which is more than most banks can send without damaging their sending domains. The workload, not the willingness of the partners, is what decides whether a sub-sector is viable for cold origination.

This is also why an open owner is not the same as a mandate. A conversation opens the door; the bank still has to win the pitch against the other advisors the owner will now call. The math above tells you how many doors you can open, not how many you will walk through. For how buy-side and sell-side work differ at this stage, see sell-side vs buy-side origination.

Why do health tech owners answer and medical practice owners do not?

The most likely explanation is how often each group has already been approached. Our data cannot prove it, because we do not see the other emails in an owner's inbox, but the pattern is consistent with it.

• Medical practices have been one of the most active consolidation targets in US healthcare for years, through physician practice management and private equity platforms. A physician owner with a good practice has very probably heard from a buyer this quarter. Our data rests on only 31 human replies here, so read the row as "very low" rather than as an exact figure.
• Imaging, med spas and owner-led services show the same pattern with larger samples: response below one per 1,000 and a do-not-contact share of 23% to 35%.
• Health tech founders are a different owner. Many built their company expecting an exit, and many have investors who expect one too. Our reading is that a founder who has already thought about the exit is easier to talk to about it, and that roll-up buyers have spent less time on this category than on practices and clinics.

The wrong-person share tells a second story. In diagnostic imaging 22% of human replies came from someone who was not the owner, and in owner-led healthcare businesses 19%. Clinical organisations put administrators in front of owners, and contact data for them is weaker. Some of the low response in those rows is a data problem a bank can fix, not a market it has to accept.

What does it look like when a healthcare bank runs it?

It looks like a standing flow of owner conversations rather than a campaign. Merritt Healthcare Advisors, a healthcare investment bank, reached 14 qualified founder conversations in its first three weeks and 133 within 90 days, and was running at about 13 new conversations a week five months in, after choosing to double its outreach volume. Multiple deals have advanced out of those conversations. Because Merritt works the sell side, the same engine surfaces owners considering an exit before they engage another bank.

On the buy side, Paras Capital, which acquires in healthcare services, had an owner reply in the first week of sending to say they had been thinking about selling and had told nobody. Across the engagement 29 positive owner conversations opened, none through a broker or an auction. That owner is the reason sell-side origination exists: the seller was real, willing and invisible to anyone waiting for inbound.

Both figures are each engagement's own published result. They show what the rates look like once a bank turns them into a standing function.

How should a healthcare bank choose its sub-sectors?

Choose on workload and saturation first, and on deal appeal second. A sub-sector you love but cannot reach produces no mandates.

1. 1. Rank the sub-sectors you cover by emails per open owner. As a rough guide, anything under about 600 can be worked by one origination function, and anything above 2,000 needs a second route alongside email.
2. 2. Check the do-not-contact share. Above about 25%, read the sub-sector as tired of being asked. Your message has to be visibly different from a buyer's, which for an advisor means leading with the owner's options rather than an offer.
3. 3. Fix the data before you blame the market. Where the wrong-person share is high, the list is reaching administrators. Rebuild it at owner level before reading the response rate.
4. 4. Size the universe against the workload. If ten conversations a month needs more emails than there are owners in your region, the sub-sector cannot be your main pipeline however attractive it is.
5. 5. Write to the owner you actually have. A health tech founder and a physician owner want different first conversations. One message across both reads as generic to both.
6. 6. Measure conversations and mandates, not opens or replies. The table already shows that reply volume and openness diverge; your dashboard should too.

The owner outreach calculator turns a sector's rate into the monthly volume a target number of conversations needs, if you want to run the numbers for your own coverage.

Where does DealSource Systems fit?

DealSource Systems runs sell-side mandate origination for healthcare investment banks and M&A advisors: owner-level lists, the written approach, sending infrastructure, reply handling and qualification, measured by the conversations it opens. It is priced at a flat $4,000 a month for a single defined thesis, with a 90-day minimum and no success fee, and the full pricing is published. The same question for other sectors is answered in home services sell-side outreach and agency mandate origination. If you want the buy-side view of healthcare, our healthcare deal origination guide covers it, and the firms that serve healthcare buyers are compared in healthcare deal sourcing firms. The other providers M&A advisors weigh us against are compared in deal sourcing firms for M&A advisors.

Conclusion

Healthcare sell-side mandates are where the choice of sub-sector matters most for an advisor. The same outreach produced an open owner every 205 emails in health tech and every 5,618 in medical practices, and the sub-sectors at the bottom are the ones buyers have been working hardest. A healthcare bank that ranks its coverage by emails per open owner, fixes its data and writes to the owner it actually has will spend its origination effort where conversations are still available, and keep the hard sub-sectors for relationships and referrals.
