Founding Engineer

Description

The company builds an autonomous one-to-one marketing AI that lets brands hold personalized conversations with each customer, improve lifecycle marketing results, and grow revenue.

Its customers include Fortune 500 companies, the San Francisco 49ers, and direct-to-consumer brands with $100M+ in annual sales.

Revenue and customer onboarding have roughly doubled continuously over the past 6 months.

AI is changing how consumer brands talk to their customers, and the company is helping define that shift.
