The Plateaued SaaS Launch Budget
A B2B workflow-software firm is launching its third product into a market where its two existing products already sell. Leadership has approved a $450,000 launch budget for the first 12 months. The product team wants 60% of the budget spent in the first quarter to 'build momentum.' Sales reports that 70% of pipeline historically comes from existing customers, but the strategy document says the new product must reach net-new logos to justify the build. The average deal size is $18,000 annually, sales cycle is 90 days, and the current marketing team has two people who are already fully allocated to the existing products. The CFO wants a payback story within 18 months.
1. How should the launch budget be phased across the year, and what principle should govern the phasing?
Read the worked answer
Front-loading 60% into Q1 is a momentum argument, not a budget argument. The governing principle is to match spend to the point where the funnel can actually convert, which is constrained by the 90-day sales cycle and by a two-person team already at capacity.
Reasoning:
- A Q1-heavy plan spends against a funnel that cannot close until Q2, so the CFO sees cost with no revenue for two quarters and the 18-month payback story collapses.
- Capacity is the real constraint. Two fully allocated marketers cannot absorb a 60% Q1 spike without pulling effort off the existing products that fund the company.
- A defensible phase is roughly 25% Q1 (foundation, messaging, sales enablement, a pilot segment), 40% Q2 (demand programs timed to close in Q3), 25% Q3, and 10% Q4 reserve for what the data says is working.
- Tie each phase to a gate: if pilot conversion in Q1 doesn't hit a pre-agreed threshold, the Q2 tranche is re-scoped rather than released automatically.
The answer is not a fixed split; it is a split justified by cycle length, team capacity, and staged release tied to evidence.
2. The strategy demands net-new logos but sales says 70% of pipeline is existing customers. How should the budget be allocated between the two, and how would you defend it?
Read the worked answer
Treat the 70% as a fact about the current business, not a forecast for a new product. Existing customers may be the faster path to early revenue but the strategy's justification is net-new reach, so both need funding with different roles.
A defensible allocation:
- Roughly 35-40% to existing-customer expansion (cross-sell campaigns, customer success plays, reference-building). This produces early revenue that supports the payback story and generates case studies the net-new effort needs.
- Roughly 60-65% to net-new acquisition (targeted demand gen, partner or channel leverage to offset the two-person team, content for a segment the company doesn't yet own).
Defense to leadership: existing-customer spend is not a substitute for the strategic mandate, it is the funding mechanism and proof engine for it. If 100% went to net-new, the 18-month payback is implausible; if too much went to existing, the product never earns its strategic reason for existing. Set a net-new logo target as the primary KPI and treat expansion revenue as a secondary, enabling metric.
3. What should the marketing team do about its two-person capacity constraint, and what is the risk if it is ignored?
Read the worked answer
Capacity is a planning input, not an execution detail. Options, in rough order of speed:
- Reallocate a defined slice of existing-product effort with explicit sign-off, so the trade-off is visible rather than absorbed silently.
- Use the budget for contracted capability (agency for production, a demand-gen specialist, partner marketing) rather than assuming headcount will be approved.
- Leverage channel or partner routes to reach net-new segments without proportional internal headcount.
Risk if ignored: the plan is approved on paper, the two marketers spread thin, existing-product performance degrades, and the launch underdelivers for reasons that look like execution failure but are actually a resourcing decision made at budget time. The CFO then sees both a missed launch and a decline in the core business, which is the worst outcome. Name the constraint in the plan and price the mitigation into the budget.
