Founder story
Founded in 2021 by a team of sales tech experts (led by the leadership at Instantly.ai). They realized that the primary bottleneck for outbound sales was the cost and technical difficulty of scaling across multiple accounts. They built Instantly to 'commoditize' outreach infrastructure, allowing founders to focus on their offer rather than their email technicals.
