The challenge
An expensive SDR team with unpredictable output
StackFlow was running outbound with two in-house SDRs. Between salaries, tooling and long ramp times, the cost per meeting was high and pipeline stayed unpredictable from one month to the next.
What we did
A managed, deliverability-first outbound engine
- Rebuilt the ideal customer profile and core messaging from scratch
- Set up dedicated inboxes and warmed domains for maximum deliverability
- Launched cold email at scale across multiple sending identities
- Optimized subject lines and copy every week from live reply data
The results
3.2x more pipeline, zero in-house SDRs
Within 90 days, StackFlow grew pipeline 3.2x, reached an 89 percent open rate and influenced more than 340K dollars in new revenue, all without a single in-house SDR on payroll.
Kocid replaced our entire SDR function and outperformed it. For the first time we have a pipeline we can actually forecast.VP of Sales, StackFlow
