Why investment banks that market during deals win the next one

Investment banks that keep marketing while they work a live deal close that deal with a pipeline already waiting. Banks that go quiet close it and start from scratch.

Most middle-market bankers know this cycle well. Between deals, they network hard. They land a mandate, disappear into it for six to nine months, and come out the other side to find their pipeline has dried up. Then the whole thing starts again. It is a feast-or-famine business, and it does not have to be.

What happens when a deal goes live

When a banker is working an active deal, business development slows down or stops completely. That is not a lack of discipline. It is the nature of the work and the hours it takes.

The cost shows up after closing. The lawyers, accountants, and wealth advisors the banker usually stays close to have not seen or heard from them in six to nine months. The prospects they were talking to before the deal have not heard from them either. In many ways, the banker is starting over every time a deal completes, and all the momentum they built is gone.

Why going quiet costs more than time

It can take a banker or a firm six to nine months to rebuild a pipeline after a deal closes, depending on what was in it and how much activity stopped during the deal. That is half a year or more of catching up, every time.

At its core, marketing is about consistency: consistent communication, consistent visibility, and consistent outreach. When all of that stops for months, the goodwill a banker has built starts to fade. It may not create distrust, exactly, but referral sources and prospects notice a firm that comes and goes. It does not feel steady, and steadiness is what marketing is supposed to create.

This matters most with referral sources. When a lawyer, accountant, or wealth advisor has a client ready to sell, the bankers on their short list are often the ones they have seen lately. Who has been active? Who did they see at the last event, have lunch with, or get a referral from? You never know when that referral is coming, and you want it to go to you, not a competitor.

It matters with owners, too. The road from an owner first thinking about selling to actually starting a process is long, and something specific usually tips the decision: a health issue, a milestone birthday, pressure from a spouse, or a sense that the next generation of leadership is ready. No one can predict when that moment will come. After years of staying in touch, the last thing a banker wants is to be invisible in the very months the owner decides to move.

The swings show up in revenue. Depending on the deals in hand, this cycle can make or break a year. A large deal closing is great news, but it often means the back half of the year goes to rebuilding the pipeline. Larger firms can stagger the work, with some bankers on deals while others are out networking, but no firm needs to live with this cycle at all.

Reputation is not the same as visibility

Some bankers push back with "My reputation speaks for itself." That is well and good, but there are other very qualified bankers doing this work, and many of them are actively marketing with teams behind them. Often the deciding factor is not reputation. It is who stays top of mind when there are plenty of good options.

Twenty years ago, an owner would usually hire a banker in their own region. Those barriers are gone. Today an owner finds the best possible fit whether it comes from an AI tool like Claude, a Google search, or a referral from a lawyer or accountant. There is a lot of competition, especially in the middle market, and no reputation guarantees a spot on the short list.

Others say, "I don't have time for LinkedIn." They don't need to. With the right help, a banker never has to open the tool. They skim and approve what is written for them, in their own voice, or they record a quick voice note that becomes a short post. It takes very little of their time.

What marketing during a deal looks like

Marketing during a deal can take many shapes, and none of them require the banker to step away from the deal for long.

Keep the banker visible on LinkedIn. A marketing partner can post relevant content that comes directly from the banker and engage with their following on their behalf. It does not replace face-to-face time, but it keeps them present. Once a month, the banker can record a 10-minute voice note or short video with their take on the sector, and marketing turns it into a post and a newsletter item. It is their voice and their thinking, with almost none of their time.

Send something useful to referral sources and prospects. A sector outlook gives lawyers, accountants, advisors, and owners something of real value while the banker cannot be out seeing them. It educates them and speaks to their business, and it keeps the firm's name in front of them.

Focus on the tier-one relationships. Time will be tight, so the banker and marketing should agree on the referral sources and prospects that matter most, then plan quick, specific ways to stay in front of them. A banker is far more likely to follow through when there is a plan, a short to-do list, and someone by their side drafting the email or the LinkedIn message and following up. One simple habit helps: a recurring 30-minute block on Friday where marketing brings the week's drafts and the banker approves or sends them in one sitting.

Hand off coverage at larger firms. While one partner is on a live deal, another partner or a senior team member can keep that partner's tier-one relationships warm with a lunch or a call.

Make the must-attend events count. If an important event happens only once a year and falls during a deal, marketing can set up meetings there in advance. The banker may not stay for the whole thing, but they make an appearance and use the time well.

Write the closing announcement before the deal closes. The close is the best reason all year to get back in touch. When the announcement, the LinkedIn post, and short personal notes to tier-one contacts are ready ahead of time, they can go out the day it closes, and the banker restarts the pipeline that week instead of months later.

Keep the website and search working. That means posting deal announcements and thought leadership, keeping the site current, and doing the work on and off the website that helps the firm show up in Google and in AI tools like ChatGPT and Claude.

What to share when you can't talk about the deal

Staying visible is not about discussing the live deal. What potential sellers want is help preparing for a sale and knowing when the right time to sell might be. Information about the industry, current multiples, and deals closing in the sector is useful to owners, and just as useful to the referral sources who have clients in that sector. That kind of steady, timely content is always safe to share.

It matters even more because a closed deal is never guaranteed to be something you can promote. Some sellers do not want publicity, and with many privately held deals, values cannot be disclosed. That is why a steady stream of other thought leadership is so important.

It is still worth asking clients early, once they sign, how they would feel about marketing the transaction after it closes. You will not know for certain until it is done, but a happy client is often glad to talk about it. Some of our clients at Marketri have recorded one-on-one videos with sellers after the transaction about the decision to sell, what the process was like, and what life looks like now. Every seller is different, so ask, set the expectation early, and respect their comfort level.

A simple rhythm that keeps running

The goal is a cadence that keeps going on its own when the bankers disappear into a deal. Here is the one we recommend:

What this looks like in practice

Marketri works with a number of middle-market investment banks, many of them focused on specific industries. One is a smaller firm that specializes in healthcare. We have worked with them on a marketing plan for a full year, and when the partners get deep into a deal, the plan keeps running.

During those stretches, their visibility in AI search tools has kept rising. Their referral sources hear from them consistently, we have produced co-marketing pieces with partners, and the firm and the partners' own LinkedIn profiles have stayed active. The result is what every banker wants: new deals keep coming into the pipeline while the partners are busy closing the ones they have.

Where to start

If you are tired of the peaks and valleys and want a steadier pipeline of deals, the first decision is who will be your marketing partner. You can build an in-house team with a marketing director and a marketing manager, or work with an outside fractional marketing firm like Marketri that specializes in investment banks. Either way, you need dedicated help.

What will not work is trying to stay consistent on your own. Those good intentions will fall away the moment an important deal takes over, because that is exactly what we see with the bankers we work with. Marketing needs a plan and a cadence already in place, so the momentum keeps going while you focus on the deal.

If you would like to talk it through, book a Growth Diagnostic with me. We will look at where your firm is today, walk through the marketing options available to you, and I will share, as objectively as I can, what I would recommend and what next steps could look like. This is a good time of year to evaluate, so you can start the new year with the right team in place and close your next deal with the following one already in sight.
