Case Study: OneSignal achieves a 65% increase in warm engineering candidates and fills 4 senior engineering roles in 3 months with Celential.ai

Boosting warm technical talent pipeline by 65%

OneSignal, a San Mateo–based customer messaging and engagement platform, needed to rapidly scale its engineering team but struggled to build a pipeline of engaged and passive high-quality candidates through traditional channels. To solve this, OneSignal partnered with Celential.ai and deployed Celential.ai’s AI-driven, human-assisted Virtual Recruiter service to expand sourcing beyond standard professional networks and surface candidates judged on capability rather than pedigree.

Celential.ai provided an active pipeline from week one, engaging 240 qualified passive candidates weekly and delivering 68 ready-to-interview candidates for three engineering roles within three months. The partnership led to four critical hires (including senior and staff engineers) in that period, a 65% increase in warm engineering candidates, and freed OneSignal’s recruiters to focus on higher-ROI initiatives.
