Rethinking Rainmakers: How Top Firms Multiply Talent and Drive 42% Better Growth
What is the state of business development culture – the mindset, behaviours, and systems that drive growth? And what separates the thriving from the merely surviving?
To answer these questions, we surveyed 235 business development leaders from 202 professional services firms worldwide (representing 130,000 employees) and captured insights from those at the front line of business development transformation.

Findings
As firms improve operational maturity and reduce rainmaker-dependence for revenue, performance measures surge.
From the most rainmaker-dependent to the least: client churn falls 60%, lateral hire success more than doubles, marketing ROI jumps 43%, and win rates climb 13%. The impact? Firms expand from 1.25 to 3.33 services per client and deliver 42% better revenue growth.
Culture archetypes
Analysing 33 factors across business development maturity, rainmaker revenue dependence, attitudes, and cultural obstacles – four business development culture archetypes emerged. These archetypes chart the evolutionary path from individual-driven to institutionalised growth:
Solo (16-22% of firms)
Business development is a mysterious art form undertaken by a select few. Personal networks drive growth, meaning success walks out the door when rainmakers leave. Pipeline tracking is minimal, technology is non-existent, and junior talent waits to be fed and inherit books of business – if they don’t leave in frustration first. Scale and consistency are impossible.
Spontaneous (33-42% of firms)
Leaders champion desired business development behaviours but provide insufficient scaffolding for consistency and accountability. Business development happens in reactive bursts by individuals, while client coordination is limited to personal cliques. Technology sits unused, with poor data undermining confidence and utility. The result: mixed signals on expectations and inconsistent client experiences.
Structured (30-38% of firms)
Firm-endorsed methodologies are executed via formal plans, opportunity pipeline management, and coaching. Meeting rhythms are established, workflows are tech-enabled, and career pathways include training and mentoring. However, remuneration and accountability structures often conflict with collaborative behaviours, and programs remain inconsistent.
Systematic (6-10% of firms)
Business development is embedded everywhere – in operations, compensation, and daily work. Collaboration is measured and rewarded. All career levels play roles in business development, which is seen as critical to superior client service. Clients receive orchestrated proactive support, with needs anticipated through data analytics and coordinated relationship management.
