SparkLoop
Newsletter referral and cross-promotion platform that helped operators grow their subscriber base through paid referrals, acquired by ConvertKit.
Manuel Frigerio (previously sold ReferralHero) and Louis Nicholls (previously co-founded Gymhopper, acquired by myClubs) launched SparkLoop in 2020. They partnered early with ConvertKit and became the go-to referral tool for indie newsletter operators. By 2023 they had reached low-7-figure ARR. In June 2023, ConvertKit (now Kit) acquired SparkLoop for undisclosed terms and integrated it into their platform, making it free for Creator Pro subscribers. Both founders stayed on.

Exit Analysis
This database tracks 78 Newsletter exits, and the ones that disclosed a price sold at a median of $5,000. Category matters more than founders expect: buyers apply different discount rates to a content business, a mobile app and a B2B tool even at identical revenue.
From founding to sale took 3.0 years. Time to exit is a decent proxy for how built-to-sell a business was: shorter, cleaner processes usually mean documented operations and fewer surprises in due diligence.
