Building BrickPicker Together: Real Tools, Real ROI

When I rebuilt BrickPicker from the studs up earlier this year, I had a specific vision in mind. I wanted to create a platform where anyone from a casual collector to a hardcore reseller could find massive value. But the best part of the last few months has been watching how you, the actual subscribers, are taking these tools and helping me shape what I build next. Just this week, I got an email from a Day 1 subscriber that completely validated all the late nights of coding. He is not a massive store owner. He just buys sets he likes and stores them in his basement. By simply using the gain in value function inside his Brickfolio, he identified which sets were actually worth his time to sell. The result? He recently moved a batch of older sets and hit a 370% ROI. He even joked that his wife is thrilled to see the boxes going out the door so he can reinvest in the hobby. That is exactly why I built the "My Business" side of the site. Other resellers are pushing the platform in other directions. A lot of the best updates lately have not been my original ideas. They are direct requests from members who are telling me exactly what is slowing them down. Here is a perfect example. A reseller messaged me recently because he was burning hours every single day price checking Amazon and Walmart to stay competitive. He told me he did not need to check all 200 of his items. He just needed to know which five actually moved. That conversation turned into Retail Watch , and it is live right now. Retail Watch shows the current Amazon and Walmart price on every set you own right next to what you paid. It narrows your entire list down to just the items that changed in the last day, week, or month. You act on the handful that matter and skip the rest. It even flags when a set drops off a retailer's shelves and goes third party only, which is usually the first quiet sign the price is about to climb. Keep in mind, this feature uses actual, real Amazon and Walmart retail sales data integrated directly into the system. It is absolute gold, and it is entirely exclusive to subscribers. The same story is happening with the API. Resellers kept telling me they wanted to pull BrickPicker data into their own repricing tools, Shopify stores, and custom dashboards. So I kept building the exact endpoints they asked for. A month ago, the API had 4 endpoints. Today it has 13. Every single one exists because a subscriber told me what they needed to automate their business. Whether you are just trying to clear out some basement shelf space for a massive ROI or you are running a high volume arbitrage operation, the subscribers inside are shaping this platform in real time. They are getting tools built for their exact workflows, and they are making their subscriptions pay for themselves many times over. And I am just getting started. The new mobile app is coming very soon, which will bring even more of these super tools front and center whether you are at home or standing in the retail aisle. If you are on the fence about subscribing, now is the time to jump in. To everyone who has already subscribed, sent me a feature request, or shared a success story: thank you. Keep them coming. You are building this right alongside me. Jeff
