A mandate signed today pays next year

Lower middle market deals took 11 to 12 months from engagement to close (IBBA and M&A Source, Market Pulse, Q2 2026). So the pipeline you need a year from now has to start before the current deal closes. Referrals do not arrive on that schedule. Outreach can.

How the calls get booked

Every message is graded before it sends

Each email opens on a fact about the reader, offers one small useful thing, and asks one easy question, in under 90 words. A separate grader scores it. A message that fails is rewritten, not sent.

Hi first name,

Saw the deal your firm announced. Congrats.

We book calls with business owners for M&A firms. For Acquire Weekly, a lower middle market M&A advisory, one month of that outreach brought 39 booked calls with owners.

The opening of a first email from our own campaign. The highlighted words come from research on that one firm.

Everything outbound needs, done for you

We build it, run it and book the calls. You take the calls. After one setup fee, you pay per qualified call, not per month.

Questions before you book

What counts as a qualified call?

A decision maker (founder, owner, managing partner, managing director or head of business development) who states the need, booked on your calendar.

Do you promise a number of calls?

No. Your offer, your market and your closing are outside our control. We promise the work we control: sending live by day 21, the agreed volume sent, a verified list you own, and messages graded before they send.

What does it cost?

One setup fee, then a fee for each qualified sales call. There is no monthly retainer. We go through the numbers on the call.

What do I pay if no calls come?

The setup fee and nothing else. There is no monthly retainer and no fee per reply.

What if the prospect does not show up?

A no-show with no notice is billed, because the qualified booking was delivered. A cancel 24 hours or more ahead is not billed, and we try to rebook. A late cancel is not billed either: the rebooked call bills when it is held. Nobody is billed twice.

When does sending start?

The first emails go out on day 14, from Outlook inboxes. Google inboxes join on day 21, and full volume is reached by day 30. Days 1 to 21 are covered by the setup fee.

Who owns the list, the domains and the inboxes?

You own the domains and the lead data and can take them any time. The inboxes are yours to use, with their logins, as a managed service: we manage them, replace every bad inbox free, and use them only for your campaigns.

What do you need from me?

One 45-minute onboarding call. Your approval of the messages and the list criteria within 48 hours. A calendar open enough to take a qualified call within 3 business days. And a short confirmation each week of which calls were held.

What happens on the first call?

Thirty minutes on Google Meet. We look at how you win clients today, what is in the way of more, and whether we can help. If we can, you will hear how. If we cannot, we will say so.

Bring one market you want more clients in

If your clients come from referrals today and you want a second source, book 30 minutes with Mairo. You leave knowing whether outbound fits your market and, if it does, how we would run it.
