A/B testing system Startups

Invisible Collector, founded in January 2016 by Pedro Mendes, is an AI-powered SaaS platform that helps utility companies and professional credit collection agencies collect debts faster through preemptive and reactive customer outreach. After a year of development with test customers, they launched commercially in November 2016 and grew to 15 customers paying an average of $3,000/month ($45k MRR) through LinkedIn-based cold outreach to CFOs and IT managers. The bootstrapped team of 6 (based in Portugal and Spain) is already cash-flow positive and is raising $500k at a $1.5M pre-money valuation to shift from direct sales to online marketing channels.
