Pipeline forecasting for Series A companies: the 90-day install
The exact 90-day plan for standing up pipeline forecasting at Series A — the point where the founder can no longer be every function.
Series A is the moment pipeline forecasting stops being optional. The founder has to step out of some of the work, the plan requires a defensible growth number, and every quarter compounds toward the next raise.
Day 1 to 30: diagnosis and instrumentation. Name the constraint, write the ICP, wire forecast variance vs actuals per quarter into the board pack.
Day 31 to 60: first live cycle at 20% of planned volume. Founder still in every review. Kill criteria written and enforced.
Day 61 to 90: ramp to full volume, hire the first dedicated operator, and hand off ops. Founder retains strategy and the weekly review.
By day 90 the metric is legible and the trajectory is defensible. This is what turns a Series A story into a Series B round.
Trap most Series A companies fall into: coverage ratios that reward pipeline theatre. It usually shows up around day 45 when the founder tries to hire ahead of the model.
The Series A version of pipeline forecasting looks small compared to what you will build at Series B. That is the point — it is a foundation, not a monument.
Frequently asked questions
RevOps — answered
- Should we start pipeline forecasting before Series A?
- Yes if the founder has time; the Series A version is the same model at higher spend.
- How much of the round should fund pipeline forecasting?
- Meaningful — often 20–30% of the growth line — but only after diagnosis.
- When do we hire the first pipeline forecasting operator?
- Around day 60, once the model has run one full cycle with the founder.
- What Series A trap should we avoid?
- Coverage ratios that reward pipeline theatre — usually a premature senior hire.
