Case Study: Finn
Finn Scales Into a Unified Omnichannel Growth Engine Across Amazon, Shopify and TikTok Shop
Overview
Finn is a premium, vet-formulated dog wellness brand built on science-backed supplements for hip and joint care, calming, skin and coat health, digestion, and daily nutrition. Its distinctive product experience earned a loyal following among millennial and Gen Z pet owners. Eva became Finn’s omnichannel growth partner in early 2026, bringing Amazon, Shopify, and TikTok Shop into one accountable operating model.
The Situation
- Core issue: a strong brand held back by disconnected channels.
Finn had real demand and a 21-SKU Amazon catalog generating an estimated $225,000 in monthly revenue and $5.7 million in trailing twelve-month revenue. Growth had stalled because each channel was operating as a separate business. The engagement began with seven structural constraints:
- Amazon growth trending down despite a Buy Box win rate above 90%
- First-page keyword coverage at just 2.31% across more than 1,600 ranking terms
- Revenue concentrated in one hero SKU while the rest of the catalog remained under-monetized
- An 80% in-stock rate creating recurring stockout risk during demand spikes
- TikTok Shop revenue dependent on sporadic influencer activity
- Shopify operating more like a storefront than a retention and subscription engine
- No unified view connecting performance, inventory, budget, and creative decisions
Eva connected Amazon Growth and Ranking, Shopify Growth and Customer Value, and TikTok Shop Management under one commerce intelligence system.
The Eva Approach
Amazon Growth and Ranking
- Rebuilt keyword architecture around category-intent clusters
- Expanded first-page visibility for high-volume terms Finn was absent from
- Restructured Sponsored Products and Sponsored Brands around contribution margin
- Refreshed A+ content and video across the catalog
- Connected inventory signals to advertising velocity
Shift: From one hero SKU carrying the brand to a full-catalog ranking strategy
Shopify Growth and Customer Value
- Rebuilt subscription and lifecycle email and SMS flows
- Improved conversion on core product and bundle pages
- Aligned on-site merchandising with Amazon best-seller data
Shift: From a brand storefront to a retention-driven channel
TikTok Shop Demand Engine
- Built an always-on affiliate and creator program
- Aligned shoppable content with Finn's playful brand identity
- Coordinated live and video shopping with the Amazon and Shopify promotional calendar
Shift: From influencer spikes to a compounding demand engine
Unified Commerce Intelligence
- Consolidated Amazon, Shopify, and TikTok Shop performance into one Eva view
- Shared SKU-level insights across channels
- Aligned inventory, ranking priorities, and channel velocity in monthly strategy reviews
Shift: From three disconnected businesses to one coordinated growth system
Omnichannel Execution
Amazon ranking and advertising priorities tied to SKU-level contribution margin
Shopify subscriptions and lifecycle flows converted more first-time buyers into repeat customers
TikTok creator and live-shopping activity coordinated with one promotional calendar
Inventory, demand, and performance reviewed in one monthly operating cadence
The Outcome
Finn moved from three disconnected channels to one coordinated growth system that compounds demand, conversion, and retention.
What Changed
Before Eva
- Amazon growth trending down
- Low first-page keyword coverage
- Revenue concentrated in one hero SKU
- TikTok revenue driven by sporadic spikes
- Shopify underused for retention
- No shared cross-channel visibility
After Eva
- Full-catalog Amazon ranking strategy
- First-page keyword visibility expanded
- Repeatable TikTok Shop demand engine
- Shopify conversion and retention improved
- One unified view across all three channels
Partnering with Eva gave us one team accountable for Amazon, Shopify and TikTok Shop instead of three vendors working off three different playbooks. We finally have a single view of what is actually driving growth, and it has changed how we plan every quarter.

Strategic Insight
Strong product-market fit can still stall when channels compete instead of compound. A connected operating model makes every win reusable across the business.
- Amazon insights improve Shopify merchandising
- TikTok demand signals guide inventory planning
- Retention data strengthens the next acquisition cycle
Omnichannel growth is not simply adding more channels
It is one connected system where every channel makes the others more effective.
