Gain Security is an early-stage cybersecurity startup building an AI-native cloud network security platform. Following a seed round, the company came to Whistle because its CEO's limited bandwidth was causing warm leads from investors and conferences to go unfollowed, and previous automated LinkedIn outreach had failed to generate results. Whistle provided a dedicated SDR to manage the CEO's network and run a personalised, feedback-focused LinkedIn campaign aimed at securing design partners ahead of the company's Series A.
11 meetings booked with 8 sales qualified leads within the first 2 months.
The design partner phase was structured as a precursor to a sales-focused outreach cycle, with the campaign set to pivot toward revenue-generating outreach once the design partner goal was met or the 1–3 month window elapsed. The stretch goal of exceeding 10 design partners positions Gain Security to enter its Series A with a stronger base of validated relationships and social proof.
Positioning outreach as a request for product feedback, rather than a sales ask, proved effective for a company whose objective was design partners rather than paying customers.
Assigning a dedicated SDR to manage the CEO's existing warm relationships addressed the core bottleneck: founder bandwidth, not lead availability.
Combining new outbound contacts with the CEO's existing network allowed the campaign to scale volume while preserving the credibility of warm introductions.
