Descriptions:
Adam Robinson, co-founder of RB2B and a repeat SaaS founder who previously exited Robly Email Marketing for $10M and scaled Retention.com to $20M ARR, narrates the complete 700-day journey from idea to $6.7 million in annual recurring revenue — built with three employees and zero outside funding. The video is unusually candid about the failures that preceded the win, including a disastrous hiring spree at Retention.com (50 hires in 60 days) and a public LinkedIn revenue prediction that badly missed its target.
RB2B’s core product is person-level website visitor identification: rather than resolving anonymous traffic to a company name (the incumbent approach charging hundreds of thousands of dollars), RB2B pushes individual LinkedIn profiles with headshots directly into Slack in real time. A freemium model — LinkedIn-to-Slack free forever, $149/month for email data and integrations — drove 1,600 waitlist signups before launch. After fixing early pricing problems with help from LinkedIn commenters, the company reached a 12.5% free-to-paid conversion rate and hit $1M ARR in six weeks.
Cold email drove 42% of total revenue on the path from zero to $4M ARR in six months. Robinson details three specific campaign types: waitlist retargeting, pure outbound to U.S.-based SaaS companies with 3–200 employees, and website visitor retargeting using RB2B’s own product — the last converting one signup per ten emails sent. The video functions as a detailed operational playbook for early-stage SaaS founders navigating product-market fit, pricing discovery, and growth channel prioritization.
