Memberify:
Scaling Sales with AI SDR Automation

Overview

Memberify is a fast-growing digital services company that needed a scalable way to fill its sales pipeline. Before working with Graystoke Systems, their reps spent hours each day prospecting, researching individual leads, and manually crafting and sending outreach on LinkedIn and email.

This manual approach was slow, inconsistent, and expensive to scale. Every new rep hire brought marginal output gains at high cost. Memberify needed a way to reach more leads, stay genuinely personalized, and actually convert outreach into booked meetings — without growing headcount linearly to do it.

Solution

Graystoke Systems built and launched a fully automated AI SDR platform to handle outbound outreach end-to-end. The system was designed to do everything a top-performing SDR does — at a fraction of the cost and without a ceiling on volume.

• Custom Lead Research — the AI automatically pulls contextual insights from each prospect's website and LinkedIn profile, generating personalized research for every single contact before a single message is sent.
• Multi-Channel Sequences — tailored campaigns run across both LinkedIn and email simultaneously, reaching each prospect on the channel most likely to generate a response.
• Automated Reply Handling — inbound replies are categorized as positive, neutral, or negative. Positive replies trigger automatic meeting scheduling; objections are handled automatically by the AI with natural, on-brand responses.
• Seamless Scaling — upload a lead list and let the system run. No risk of platform flags, no manual bottlenecks, no babysitting required.

Features Implemented

Results & Outcome

In the first month alone, 900 leads were pushed through the system and 10 qualified meetings were booked — a 1.1% meeting rate that outperformed expectations from day one. At just $200 per month in platform costs, the system delivered meetings at a fraction of the cost of traditional outbound hiring.

The ROI was clear immediately. Instead of burning rep hours on manual prospecting, Memberify's team now runs outreach at scale, books meetings automatically, and focuses entirely on closing deals. The sales team transformed from prospectors into closers almost overnight.

What was once a bottleneck — inconsistent, expensive, manual outreach — became a repeatable, low-cost engine for pipeline growth. The system scales as Memberify grows: more leads in, more meetings out, with no additional headcount required.
