How would you grow Orium's existing client portfolio?
Why they ask: Do you have a system for expansion, or do you wait for inbound? They want a designed, forecastable motion grounded in account planning and whitespace.
- Start from the data: tier the book by value and expansion potential, not just current revenue.
- Build whitespace maps (our services × their buying centres) — the red cells are the pipeline.
- Make delivery the expansion radar; account leadership orchestrates the close (LAER).
- Instrument it: account plans, QBRs, forecast categories, and a weekly expansion review.
- Anchor to NRR — the majority of value creation is expanding existing relationships, not new logos.
- McDonald's: $5M+ retainer renewal + 10% annual growth.
- Apply Digital: multiple $8M+ P&Ls; sourced a $5M account at 70%+ margin.
- Ford CRM: $3M growing $1M YoY.
I'd grow it as a designed motion, not luck. Tier the book by expansion potential, build whitespace maps of where we deliver versus where we could, and make delivery the radar that surfaces signals while account leadership orchestrates the close. Then I'd instrument it — account plans, QBRs, weighted forecast — and manage to NRR, because the cheapest growth is expanding the clients who already trust us. I did exactly this growing McDonald's 10% a year on a renewed $5M retainer.
Growth in an existing portfolio is the cheapest growth there is — McKinsey's point that most value creation comes from expanding existing relationships, not new logos. So I'd treat it as a system. First, segmentation: tier the book by strategic value and expansion potential, not just current ARR, and match coverage to value. Second, whitespace: for each strategic account, map our service lines against their business units and buying centres — the un-penetrated cells are the expansion pipeline. Third, the engine: in a consultancy, delivery teams have far more client contact than sales, so they're the radar — I'd define a clear handoff where delivery surfaces signals and account leadership orchestrates the close, the Expand and Renew stages of LAER. Fourth, instrumentation: living account plans, QBRs that centre on value delivered and next-quarter priorities, evidence-based forecast categories, and a weekly expansion-and-risk review. And I'd hold the whole thing to NRR and gross retention. I've run this pattern — renewing McDonald's $5M retainer while growing it 10% a year, and carrying $8M-plus P&Ls at Apply Digital where I sourced a $5M account at 70%-plus margin.
“I'd build strong relationships with our clients and look for opportunities to do more work with them, and make sure we're delivering great quality so they want to expand.”
Expansion is a designed, forecastable motion: tier by potential, whitespace-map every strategic account, make delivery the radar and account leadership the closer, instrument it with plans/QBRs/forecast, and manage to NRR. I've renewed a $5M retainer while growing it 10% a year doing exactly this.
- "How do you stop delivery just order-taking?" — RACI + rules of engagement, and credit/incentives for surfacing expansion.
- "What's your NRR target?" — don't invent a number; talk bands (best-in-class enterprise 120%+) and that you'd baseline Orium's first.
