Details
Customer.io sends messages based on what users actually do in your product. Founded by Colin Nederkoorn, “fundstrapped” (took some money but runs like bootstrapped). Took 18 months to hit $10k MRR, now at $100M ARR. Great for SaaS doing product-led growth.
Userlist is email automation that actually understands SaaS. Track users AND companies, trigger emails based on product usage, run onboarding sequences that adapt to behavior. Built by Jane Portman and Benedikt Deicke specifically because generic email tools don’t get SaaS.
