Featured work

• Emma&Noah Custom Bundle Builder

  Emma & Noah needed to increase Average Order Value (AOV). Grumspot developed a custom "Mix & Match" bundle builder for Shopify Plus, featuring dynamic discount thresholds and a seamless custom UI. The solution optimized the user journey for complex product variants and successfully boosted AOV by 61%.

• Ryzon Bundles

  We built a custom 'Theme Bundle' app for Ryzon to boost AOV. Shoppers fill category slots using a 'visual workbench' sticky bar that tracks progress and simplifies navigation. By using completion bias, we nudge users to finish their full kits. Everything we do at Grumspot is based on proven behavioral science. For a science-based approach to your ecom store, book a call with us.

• JoinBetter

  Custom build and migration from WordPress for a Y-combinator backed company providing support and products for people with chronic diseases. It was a complex job, because they offer in-house care for people with chronic disease along with products for their conditions and it is all priced by request which needed additional setup after the migration.

• ABsolutely

  A fully designed and built public Shopify app for A/B testing, built in-house at Grumspot for a client. We managed everything from the initial MVP build of the app and the ongoing feature development, as well as the onboarding of merchants almost 2 years after launching. Apart from custom builds and apps, we also do high-performing public apps written with enterprise-grade code.

• SelfServe

  Grumspot built Self-Serve Order Editing in-house to automate post-purchase workflows. It lets customers edit orders, slashing support tickets and boosting CX. We build public apps like this to scale brands via automation. Everything in ecom should be based on proven behavioral science tactics, that’s exactly what we do at Grumspot.

• LuxorroStore build or redesignJan 19, 2026

  Absolutely stunning work—Stan and the team are incredible! I cannot recommend Grumspot highly enough! Stan and the team built two new pages for my website, and the results are simply stunning. From start to finish, the process was seamless. I was particularly impressed by their communication—they were responsive, clear, and truly listened to what I needed. It’s no surprise to see them listed as Shopify Partners now; their professionalism and quality of work are top-tier. If you are looking for a team that delivers amazing results and is a joy to work with, look no further than Grumspot. Extremely highly recommended!
