The Cost of Hiring

The cost of adding In-House Reps

A single in-house SDR seat costs a bit more than just their salary. Once you add employer burden, tooling, management, etc., you’re looking at $9,750 to $15,000+ every month. These benchmarks show the low, typical, and high scenarios of where most teams land.

“I had zero luck with cold outreach before partnering with OSP, but 2 days in and we had 18 meetings booked. No idea how these guys do it, but we had so many meetings it was overwhelming!”
