The 100-Day B2B Growth Plan

Day 100 is when the story gets written. Boards, investors and sales teams all decide in those first months whether growth is under control — or whether leadership is just busy.

The Expensive Default

Under pressure, most teams do more: more channels, more tools, more content. Spend goes up in week two. Learning doesn't — because nothing was set up to measure it. This plan is different: the first 45 days deliberately slow down to diagnose and fix, so that every euro spent after day 46 compounds.

Four Phases, Three Gates

The plan runs across four tightly sequenced phases — each ending with a leadership gate before you're allowed to spend more:

• Phase 1 (Days 1–15): Diagnose the funnel. Pull 12 months of data, interview customers and lost deals, and produce one page everyone agrees is reality.
• Phase 2 (Days 16–45): Fix the foundations. Align on shared funnel definitions, build a live dashboard, and enforce a 24-hour MQL follow-up rule.
• Phase 3 (Days 46–75): Run three focused experiments — not thirty — each with a written hypothesis, a success metric and a kill date.
• Phase 4 (Days 76–100): Scale the winner, kill the rest, and present a one-page board update showing what moved and why.

Six Practical Tools Included

The guide includes six ready-to-use frameworks: a revenue driver tree, funnel definitions with service levels, the 24-hour follow-up rule, an ICE prioritisation matrix, an experiment card template, and clear scale/iterate/kill decision rules.

The Day-100 Check

A 10-question self-audit helps you and your leadership team score honestly whether you've built an engine or just run campaigns. Scores of 8–10 mean you're ready to scale; anything lower tells you exactly where to restart.
