AI SDR agents for Series A companies: the 90-day install for professional services firms in the Benelux region
The exact 90-day plan for standing up AI SDR agents at Series A — the point where the founder can no longer be every function. Written for managing partners and heads of business development at consultancies and agencies in the Benelux region.
This edition of the Growth Broker playbook is written for managing partners and heads of business development at consultancies and agencies operating in the Benelux region. In this market, Benelux buyers reward multilingual specificity and a pitch that respects local nuance, so the way you install AI SDR agents has to be shaped to that reality from day one.
Series A is the moment AI SDR agents 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 qualified meetings per $1k of AI spend per week 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.
Inside professional services firms, the binding constraint is almost always senior partner time, not lead volume, and in the Benelux region it is compounded by the fact that local nuance and language fit, not scale is what actually gates growth. AI SDR agents is only useful here when it is pointed at both constraints at once.
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: spraying generic sequences from an unwarmed domain and burning sender reputation. It usually shows up around day 45 when the founder tries to hire ahead of the model.
The Series A version of AI SDR agents looks small compared to what you will build at Series B. That is the point — it is a foundation, not a monument.
Concretely for professional services firms in the Benelux region: one signed retainer typically funds the entire growth program for a year, and one anchored Benelux customer becomes the reference the rest of the region asks for. That is the reason it is worth installing AI SDR agents deliberately for this market rather than importing a playbook designed for somewhere else.
