Direct answer
Before Series B, a bad AE or SDR hire costs salary plus momentum: stalled pipeline, poisoned reference accounts, and months of founder time spent managing underperformance instead of closing deals. Invisible costs routinely exceed a placement fee by a wide margin. That is why mock-call vetting, structured pre-screens, and a 90-day replacement guarantee matter more than the cheapest headline fee.
Salary is the smallest line item. Burned pipeline, poisoned accounts, and lost time are where bad AE hires actually destroy early-stage companies.
Before Series B, a bad sales hire doesn't just cost salary, it costs momentum, and momentum is the only thing a pre-Series B company actually has. A misaligned founding AE can work your best inbound for a quarter, fail to close a single account, and leave you with a poisoned reference list and no pipeline when they churn. A wrong SDR builds the wrong sequences, burns your domain reputation, and damages the ICP relationships you need for Series A proof points.
The visible costs are salary, OTE draw, equity, and agency fees. The invisible costs are founder time spent on performance management instead of closing deals; the morale hit when a mis-hire sets the tone for how the sales team operates; the opportunity cost of accounts that went cold because a seller who should not have been there worked them first. At Seed through Series A, those invisible costs often exceed the placement fee by three to five times.
That's why speed without quality is a false economy when we recruit, and why quality without speed burns the post-raise pipeline window. The goal is calibrated hiring: stage-appropriate candidates who have been stress-tested through structured pre-screens and live mock cold calls where they sell your actual product, not candidates who interview beautifully and ramp slowly.
A 90-day replacement guarantee doesn't make a bad hire free (you still lose the time and the pipeline), but it removes the fear that trying a new recruiting partner means eating a full fee if the hire fails for fit or performance. Combined with pay-on-start economics, it aligns incentives: we only win when you get a seller who sticks and ramps.
If you're about to open a founding AE or SDR seat, optimize for the cost of being wrong, not only the cost of the search. Book a call and we'll walk you through exactly how we vet sellers before they reach your loop.
