Best way to dip your toe into inside sales
Our business has a relatively small TAM, and many of the key players attend industry events/conferences, which has historically been our biggest business development driver. We’ve recognized there’s a healthy slice of the market that we needed to find another way to get in front of. We didn’t have a tech stack or SDR manager, so memoryBlue’s ability to take that all off our plate while also enabling us to try the cold-calling experiment was very valuable. After almost a full year of running the memoryBlue campaign, we have the most robust sales pipeline we’ve had in my five years.

Exceptional SDR Outsourcing Experience with memoryBlue
I appreciate their professionalism, responsiveness, and the quality of their SDRs. The onboarding process was smooth, and their team communicates regularly with clear updates and actionable insights. They truly feel like an extension of our internal sales team, always striving to exceed expectations. If you’re looking to scale your outbound sales efforts without the overhead of hiring and training internally, memoryBlue is a great partner. Be prepared to invest some time upfront to align on messaging and goals, but expect strong communication and measurable results. Their team takes on the heavy lifting of prospecting and lead qualification, which allows our in-house sales team to focus on closing deals. This has led to a noticeable increase in qualified meetings and overall sales efficiency.
