Marsh McLennan

Through 2019, Marsh McLennan's new client acquisition relied primarily on traditional relationship-driven selling — brokers and consultants building personal networks with risk managers, CFOs, and HR leaders. New logo acquisition was slow and expensive, with a sales cycle averaging 9-12 months for mid-market clients and 18+ months for enterprise accounts. The cost of new client acquisition was approximately 3-4x the cost of retention, and the firm's organic revenue growth averaged 3-4% annually across its four businesses (Marsh, Guy Carpenter, Mercer, Oliver Wyman). Digital engagement with prospects was minimal — the firm had no self-service tools, limited digital marketing, and relied on in-person events and referrals.

Starting in 2020, Marsh McLennan invested in building a digital-first client acquisition engine:

• Digital risk assessment tools: Launched free and freemium digital risk assessment tools (cyber risk scorecards, climate risk dashboards) that allowed prospects to self-engage with Marsh's intellectual property before a broker conversation. These tools generated qualified leads at a fraction of the cost of traditional prospecting.
• Mid-market digital platform (Victor): Expanded Victor Insurance (acquired 2015), a digital-first managing general underwriter, as a new client entry point. Victor provided automated online quoting and binding for small and mid-market commercial insurance, converting businesses that were too small for traditional Marsh broker coverage into digital clients.
• Content-led demand generation: Invested in thought leadership content (Global Risks Report with WEF, Mercer Total Remuneration surveys) distributed digitally, generating inbound leads from risk managers and HR leaders researching specific topics.
• Cross-brand account development: Once a new client entered through any of the four businesses, a systematic cross-referral process introduced the other three — a Marsh insurance client would receive outreach from Mercer (benefits), Oliver Wyman (strategy), or Guy Carpenter (reinsurance) as relevant.

• Sustained organic growth acceleration: Organic revenue growth reached 9% in 2023, more than double the pre-2020 average of 3-4%, driven by both new client wins and expanded existing relationships.
• Revenue growth: Total revenue grew from $16.7 billion (2019) to $23.0 billion (2023), a 38% increase in four years.
• Victor digital platform: Victor processed over $4 billion in gross written premium, serving as a digital entry point for mid-market clients who could later graduate to full-service Marsh brokerage.
• New client acquisition efficiency: Digital lead generation reduced average cost-per-qualified-lead by approximately 40% compared to traditional prospecting methods, per management commentary.
• Cross-sell: Clients using 2+ Marsh McLennan businesses increased, with cross-referred clients showing 25% higher retention than single-business clients.
• Timeframe: 2020-2023 (ongoing).

• Marsh McLennan's four complementary businesses (insurance, reinsurance, consulting, benefits) provided natural cross-sell paths that single-line competitors could not replicate
• Victor's digital insurance platform provided a scalable, low-cost acquisition channel for mid-market clients
• Proprietary data and research (WEF Global Risks Report, Mercer surveys) generated organic inbound demand at near-zero marginal cost
• COVID-19 forced clients and brokers online, accelerating adoption of digital engagement tools that would have taken years in normal conditions
