The Rainmaker Myth: Why Relying on One Person to Drive Revenue Is a Firm-Level Risk

By Chris Cocca

Every professional services firm has one partner who seems to know everyone. The one who closes deals over dinner, lands clients through sheer force of personality, and carries a book of business that makes the rest of the firm’s numbers look modest by comparison.

You are proud of that person; you probably built a lot around them. And that is exactly the problem.

Throughout my years of working with accounting and professional services firms, I have seen this scenario play out more times than I can count. A firm grows, sometimes impressively, on the back of one or two exceptional rainmakers. Then something changes: the rainmaker retires, gets poached, or burns out. Suddenly, the firm is staring at a pipeline that was never really a pipeline; it was one person’s Rolodex.

This is what I call the Rainmaker Myth: the belief that exceptional individual talent is a growth strategy. It’s not; it is a single point of failure dressed up as success.

The Math Does Not Work Long-Term

Here is a question I ask every managing partner I sit down with for the first time:

“If your top rainmaker walked out the door tomorrow, what would your revenue look like in 18 months?”

Most partners go quiet. That silence is a business risk that compounds over time.

When growth depends on one person, everything else in the firm becomes secondary to keeping that person happy, busy, and in the building. Succession planning stalls and junior partners don’t develop. The firm’s value is concentrated in a relationship that walks out the door every evening. 

A firm that cannot demonstrate distributed revenue generation is worth less than one that can. Full stop.

How It Happens, And Why Firms Let It

The Rainmaker Myth does not develop overnight. It grows gradually, through a series of reasonable decisions that accumulate into a structural problem.

A partner with natural relationship skills starts landing clients, then they get more autonomy, more resources, and more room to operate. Other partners watch and quietly conclude that business development is “not their thing.” The culture quietly sorts itself into those who sell and those who serve.

Over the years, this calcifies. The rainmaker’s book grows, and everyone else’s stays flat or depends on overflow. When leadership finally decides it is time to build a BD culture, they run into a wall: partners who have been implicitly told for years that business development is someone else’s job. That is a hard thing to change, but it is reversible.

The DNA Question You Have to Answer First

Before you can build a culture of business development, you have to understand what you are actually working with. Not every partner has the same natural aptitude for business development. Some partners are wired for relationship-building and new business conversations, while others are exceptional client servers who can grow existing accounts. Still others are better suited to referral activation or subject matter expert positioning.

The mistake most firms make is treating business development as a uniform expectation. Everyone gets the same goal, the same training, the same nudge to “get out there.” And then leadership is confused when results are inconsistent.

A smarter approach starts with assessment. Understanding each partner’s business development DNA – their natural strengths, their gaps, their motivation style – is the foundation of a development plan that actually produces results. You cannot build a team of rainmakers without first knowing what each person is capable of growing into. A good example of a “DNA” assessment for professional services firms is Objective Management Group (OMG), which is used by Evergrowth clients to help them understand the BD strengths and weaknesses of their teams.   

Development Plans Are Not Optional

Once you understand your team’s DNA, the next step is to build individual development plans and hold people accountable for them quarterly. This is where most firms drop the ball – they do the assessment, identify the gaps, then they file the results and move on.

A real development plan is documented and specific. It includes skill-building milestones that get reviewed every quarter and are tied to coaching conversations, not just annual reviews.

Partners who know exactly what they are working on and who are held to it consistently get better. That incremental improvement, multiplied across a team of eight, twelve, or twenty partners, compounds into a firm-wide capability that no single rainmaker can match.   When you take it down below the Partner level, growth explodes.  

Coaching Is the Multiplier

Assessment tells you what to work on, development plans tell you how, and coaching is what makes it stick. The firms that successfully move past the Rainmaker Myth are not the ones that did a training event and hoped for the best. They are the ones who built a regular rhythm of coaching conversations that are structured, specific, and tied to real deals.

That means reviewing pipeline activity, debriefing on proposals that were won or lost, practicing difficult conversations before they happen, and asking partners what is getting in the way and removing those obstacles.

Coaching does not have to be a full-time job, but it does have to be consistent. An hour a week of focused, intentional development activity will outperform a two-day training retreat that happens once a year.

What the Other Side Looks Like

Firms that break the Rainmaker Myth do not replace their top rainmaker with a committee. They build a team where business development is distributed, expected, and supported. Every partner understands their role in growth, and the firm has a pipeline that reflects contributions from multiple people. Revenue is not hostage to any single relationship. And when, not if, a key person leaves, the firm keeps moving.

I have watched firms make this transition. It takes time, intention, and a willingness to invest in the unglamorous work of assessment, development planning, and coaching. But the alternative of crossing your fingers and hoping your rainmaker stays forever is not a strategy. It is a risk you are choosing to live with.

The Bottom Line

Rainmakers are an asset. They are not a plan.

If your firm’s growth depends on one or two exceptional individuals, the work ahead is not finding more people like them; it is building a system that develops business development capability across your entire team.

That’s the mission that  Evergrowth was built for. We help firms turn business development from a trait a few people happen to have into a discipline the whole organization can learn. The goal isn’t to replace your rainmakers; it’s to make sure your growth no longer depends on them.

Taking the first step is critical.   I recommend starting with OMG assessments for your team and understanding your overall “BD DNA”.    I am happy to help you get started on the path to more sustainable growth.
