The hottest exit in the Shopify app world came out of a college dorm room. Four Canadian students built a post purchase upsell app called AfterSell between classes. A few years later they sold it to Rokt for over eight figures. And they are still there building. I sat down with two of the co founders, Armon and Varun, on Trenches to understand how they actually did it, what they got wrong along the way, and what the top Shopify brands are doing right now. Condensed my notes below. ✅ The MVP Was Built by a Guy on Upwork Armon is not an engineer. He was running dropshipping stores, saw post purchase upselling work on his own sites, and paid a freelancer to build the first version. Then he posted screenshots in Facebook groups and gave the app away for free in exchange for feedback. That got them 50 to 100 users, and only then did he go looking for technical co founders. ✅ Product Market Fit Took Three Years, Not Three Months After twelve months of grinding they were at $5K MRR and losing money every month. The real inflection point was Shopify releasing its native post purchase extension, which turned a high friction thank you page widget into a true one click upsell and multiplied conversion rates overnight. They won because they were already in the arena when the platform shipped that update. ✅ Building Eight Apps Almost Killed the One That Worked To get from $30K MRR to $1M ARR they assumed the answer was a portfolio of apps. At one point they had eight either live or in development, including order tracking and product quizzes. Every single one was eventually shut down or sold off. What actually got them there was going all in on go to market for the app that was already working. ✅ Go to Market Was the Bottleneck, Not Engineering Facebook groups, app store SEO, and reviews got them to $30K MRR and then plateaued. The unlock was realizing merchants want hands on help setting up their offers, so they started doing merchant success with top brands, posting the results on Twitter and LinkedIn, and building a 100K follower TikTok for their second app. In 2023 they went from $1M to $6M ARR on the back of that. ✅ They Are Burning Millions in SaaS Revenue on Purpose Any merchant can now use AfterSell for free if they run Rokt's third party offers on their confirmation page. They estimate this has cost them millions in ARR. Their view is that AI makes software cheaper to build every month, which makes SaaS pricing less defensible over time, and they would rather get ahead of that than get undercut by someone else. ✅ The Best Post Purchase Offers Are Logical, Not Emotional The customer already bought, so you do not need to sell them on why they need the product again. The top brands give one simple logical reason to buy more, like telling the customer that the best results come from people who take it for four months, so they should commit now at a discount. The top supplement brands on AfterSell are adding $50 to $60 in revenue per post purchase visit with take rates of 20 to 30 percent. ✅ The Brands Scaling Fastest Right Now All Share the Same Profile They sell one broad product with 80 to 90 percent gross margin that multiple avatars can buy. They run teams of fewer than five people. And they use AI workflows to pump out thousands of creatives and hit every angle at scale. The video editor is the one role nobody has managed to replace yet. ✅ Cross Promotion Between Apps Does Not Work Everyone thinks they can swap email lists with a complementary app. In practice one side always gets more value and the channel never really moves the needle. The partnerships that actually worked were clean integrations, like co launching a subscription upgrade feature with Recharge, Skio, and Loop. ✅ The Acquisition Started as a Partnership Conversation Rokt initially said they would partner but had no interest in buying. A few months later the AfterSell team came back having hit double the numbers they had promised, and that is when it got serious. From that point to signing took about three to four months, and a broker who had already sold his own company to Rokt is the reason the deal happened at all.
