About
Built by a Shopify merchant, for Shopify merchants.
UpsellShark exists because Gustav, the founder, runs multiple Shopify stores doing about $5M USD per year. The apps in this suite started as tools he built for his own stores in boat equipment, clothing, and design - and couldn't find anywhere else.
The thesis
One app per problem. Fair pricing. Nothing extra.
Most Shopify apps try to be everything: a CRM, a popup builder, an email tool, an analytics dashboard, and a loyalty program in one. They cost $99/mo, take a week to set up, and break when Shopify changes the theme spec.
UpsellShark goes the other way. Each app solves one specific job - find duplicate product images, build a vendor directory, sell event tickets, generate lifestyle product photos. We charge $4.99 to $14.99/mo, install in minutes, and stay focused on the job.
Every app ships with a free plan or a free trial so you can prove the value before spending anything. If an app doesn't solve your problem, uninstall - we won't fight you for the credit card.
Who's behind this
Gustav, founder · Shopify merchant
Gustav
Founder, UpsellShark · Active Shopify merchant
I'm a Shopify merchant first. I run multiple Shopify stores doing about $5M USD per year in revenue across boat equipment, apparel, and design products. The apps in UpsellShark exist because I needed them in my own stores and couldn't find anything that fit the bill.
That gives me an unfair advantage when it comes to knowing what merchants actually want, not what app developers think merchants want. Every feature has been validated against my own catalogs, my own customers, and my own daily operations before it shipped to anyone else.
It also means feature requests get implemented quickly. If you email support@upsellshark.com with a reasonable request, there's a good chance I've already needed it myself - and most asks ship within days, not quarters.

How we build
Opinions baked into every app
Built by a merchant who needed the apps
Every app was first built for our own Shopify stores. Features land because they solved a real problem we hit, not because someone in a roadmap meeting thought it might sell.
Free plan or free trial, always
No app ships without a way to prove value before spending. Most apps over-charge for what they actually do; the free plan keeps us honest.
Feature requests get built fast
When you email asking for a feature, there's usually a high chance we've needed it ourselves. Reasonable asks ship in days, not quarters. No PM committee, no roadmap waiting list.
Shopify Managed Pricing only
Billing runs through Shopify's own system. We don't store your credit card, don't charge through Stripe, don't have a separate dashboard. Less to manage, less to break, less to trust.
GDPR-first
Every app implements all three GDPR webhooks (data request, customer redact, shop redact) from day one. Six-locale admin UI (English, Spanish, French, German, Portuguese, Danish). EU-built defaults.
Built for Shopify quality bar
Every app targets Core Web Vitals, accessibility, and security standards in Shopify's Built for Shopify program. Fast pages, no theme bloat, no scary script injection.
No "AI" theatre
We use AI when it solves the actual problem (lifestyle photo generation, perceptual image hashing). We don't bolt a chatbot onto every screen and call it innovation.
