What we do

Discovery happens where intent lives — not just on Google

A vertical search engine indexes a single domain in depth. For shopping, that means live price, stock, sizes, reviews and availability — returned as focused, comparable results a shopper can act on. We build these engines and scale them across markets and categories, one at a time.

01 — Build

We build from scratch

We design and engineer vertical search engines end to end — indexing, matching, pricing, sizing and editorial content — purpose-built for a single high-intent niche.

02 — Scale

We scale across markets

Once an engine works, we take it cross-border and into new categories — new languages, currencies and verticals — on one shared, proven platform.

03 — Perform

We deliver for advertisers

We connect retailers and brands to ready-to-buy shoppers on a performance basis — measurable, incremental revenue with dedicated, managed attention.

General search

Broad, but shallow

  • Every topic, mixed intent
  • A list of links to sift through
  • No live price, stock or size data
Vertical search — what we build

Focused, and built to convert

  • One niche, indexed in depth
  • Live price, stock, sizes and reviews compared side by side
  • Shoppers arrive ready to buy
Our story

More than a decade building vertical search engines

From a single sneaker niche to a portfolio of search engines across five markets. Every platform has made the next one sharper.

2013
The beginning

Sneakers4u launches

Our original sneaker price-comparison engine goes live — the flagship that proved shoppers want focused, comparable results, and the foundation everything since is built on.

2020
Next generation

Solezilla, rebuilt from scratch

A decade of learnings poured into a ground-up, next-generation sneaker search engine — deeper indexing, richer data and a far better shopper experience.

2023
Going international

Solezilla.com & Solezilla.de

The engine crosses borders: Solezilla.com for Europe, the UK and the US in native currencies, and Solezilla.de for the German-speaking DACH market.

2025
New verticals

Lenzenzilla — beyond footwear

The model moves into a new category with a contact-lens search engine — the first step in a roadmap of "-zilla" verticals across fashion, luxury, beauty and collectibles.

Today
The engine, scaling

A portfolio of vertical search engines

Five platforms across five markets, 150+ retail partners and 1.4M+ live offers — and a pipeline of new categories in build. We scale what works, one vertical at a time.

General search hands you ten blue links. A vertical search engine hands you the one answer you were shopping for — the right product, the best price, in stock, in your size. That is where we build, and where intent turns into revenue.

Search + comparison + content

Not just feeds — a content engine

Our vertical search engines pair live price comparison with real editorial content. That combination drives organic discovery and keeps shoppers engaged far longer than a bare product feed.

Editorial model pages

A dedicated page for every sneaker — specs, colorways, buying context and our proprietary Hypescore. Editorial content produced at scale.

Blogs & buying guides

Release news, buying advice and trends across Solezilla, Solezilla.com, Solezilla.de and Sneakers4u — the reasons shoppers arrive before they even search.

Multilingual by market

Grounded content in Dutch, English and German — written for each market, not machine-translated as an afterthought.

For brands: content-driven organic discovery (SEO), an engaged and ready-to-buy audience, and room for brand features, sponsored content and product storytelling — built into the platforms where purchase decisions are made.

Built on 12+ years of vertical-search expertise — 500+ brands, 150+ webshops, 5 markets.
