icCube scales international B2B outbound with Amplemarket Duo AI copilot, achieving 6.3x reply rates and 50% more meetings booked

The problem

icCube struggled to expand beyond its domestic Swiss SaaS market and win new customers against well-known incumbents. The core challenge was timing outreach precisely — reaching prospects too early or too late resulted in lost opportunities, while the product's niche fit was difficult to communicate before buyers had already committed to a larger competitor.

First attempt

icCube's previous outbound approach was high-volume and low-personalization — sending nearly identical messages to many people with only name and company fields changing. Despite targeting far more leads via outbound than inbound, conversion rates were equivalent, and the effort produced only three clients over three years.

“it took me maybe 15 minutes a day to go through the leads and signals — and the alternative would be getting three people to do all that lead research and personalization manually, full-time”

“I changed our tone of voice prompts to ask Duo to create first touches in the prospect's native language. So I ended up sending a Russian email and actually getting a response!”
