Regal.io is a phone and SMS outreach platform that uses AI to personalize outreach, increase conversion, and boost revenue for B2C brands. The company was founded by Alex Levin and Rebecca Greene after they found that calling "abandoned" customers increased conversion rates at double the original rate. Regal.io leverages Twilio's APIs for programmable voice and conferences, SMS, and conversations to power calls, transfers, and voicemail drops, allowing users to build faster and focus on key differentiators. The company has raised $42.1 million in funding and has driven over $2 billion in revenue for its customers since its founding in 2020.
