The challenges

The challenges

Manual Outreach Bottleneck


B2B companies struggled to scale outreach manually. Personalization was time-consuming, and reaching enough prospects was impossible without a large team.

Solution: AI personalization engine that generates hyper-personalized emails at scale, enabling companies to reach thousands of prospects with the quality of manual outreach.


Existing Tools Land in Spam

Available automation tools were buggy and caused deliverability issues, destroying sender reputation and making cold email ineffective.

Solution: Built platform with highest-possible deliverability infrastructure, email warmup systems, and anti-spam best practices ensuring emails reach the inbox.


Time to Launch

Setting up cold email infrastructure traditionally took weeks—configuring domains, email accounts, warmup, sequences, and tracking.

Solution: Complete turnkey system allowing businesses to launch their entire cold email operation within 24 hours, from setup to first campaigns.
