Stamped vs Tiergain in 2026: reviews platform or bundle architecture?
Stamped builds trust and loyalty through reviews and points. Tiergain builds bigger orders through bundle tiers. Different levers, both essential.
Quick Verdict
Stamped combines reviews, loyalty, and UGC. Tiergain builds bundle architecture with combined rewards. For trust + retention, use Stamped. For AOV architecture, use Tiergain.
What is Stamped Reviews & UGC?
Stamped Reviews & UGC is a Shopify platform that combines product reviews, photo/video UGC, NPS surveys, loyalty points, and referral programs. It offers a comprehensive social proof and retention suite. Pricing starts free with paid plans from $23/month. It has a 4.7 rating across 6,000+ reviews.
Where Stamped Reviews & UGC Falls Short
Trust and Retention Platform, Not AOV Architecture
Stamped builds trust (reviews) and loyalty (points). It does not build the bundle experience that determines cart size. High trust at low AOV still means small orders.
No Bundle Builder or Progressive Cart Rewards
Stamped cannot create tiered bundles with combined rewards. It rewards after the purchase through points, not during the purchase through bundle tier incentives.
Loyalty Points Can Compress AOV on Redemption
When customers redeem Stamped loyalty points for discounts, AOV drops. Bundle rewards (gifts, shipping, exclusives) lift AOV. The mechanisms push revenue in opposite directions.
Platform Breadth vs Bundle Depth
Stamped does reviews + loyalty + referrals. Tiergain does bundles deeper than any other app. For stores where bundles are the primary AOV lever, depth beats breadth.

Why Merchants Switch to Tiergain
22-34% immediate AOV lift from bundles
Tiergain lifts AOV immediately by building bigger carts. Stamped lifts trust gradually through review accumulation and loyalty over time. Both are valuable - the AOV lift is larger and faster.
Bundle rewards add value. Point redemption subtracts it.
A Tiergain bundle tier that unlocks free shipping + a gift adds $24 in perceived value. A Stamped point redemption of $10 off reduces order value by $10. For AOV, the directional impact is opposite.
Structured bundle experiences that review platforms do not build
Mix-and-match builders, gift set builders, anchor product flows - these shopping experiences change cart size. Review widgets and loyalty points do not change how customers shop.
Frequently Asked Questions
Can I use Tiergain alongside Stamped?
Yes. Stamped builds trust (reviews) and loyalty (points). Tiergain builds bigger carts (bundles). Trust + loyalty + bundle architecture = maximum LTV. They complement each other perfectly.
Is Tiergain cheaper than Stamped?
Both have free plans. Stamped paid plans start at $23/month. Tiergain Pro is $50/month. For the complete trust + loyalty + bundle stack, running both costs $73-100/month.
How long does it take to set up Tiergain?
Most merchants go live with their first bundle in under 10 minutes. Tiergain uses Shopify Theme App Extensions - drag and drop, no code editing, works with any theme.
Should I invest in reviews or bundles first?
Reviews first if you have fewer than 10 reviews per product. Trust is the first barrier. Once you have social proof, add Tiergain for bundles. Trust gets one item in the cart. Bundles get three.
Do Stamped reviews help Tiergain bundle conversions?
Yes. Products with reviews convert better inside bundles. If every item in a 3-product bundle has 5-star reviews, the bundle purchase rate lifts because trust applies to every component.
