Customer Stories

"Actually optimizing for business metrics we care about."

"With our legacy search vendor, we struggled to provide our customers with an advanced, enjoyable product discovery experience, and other vendors struggled to provide value during sales conversations. Constructor changed that.

Not only did they provide actionable insights about our site during the sales process, but their entire product discovery platform allowed us to provide personalized results for all our users while actually optimizing for business results we care about."

Britt Ballard

Senior Director of Engineering, Bonobos

"We’re thrilled with the results we’ve seen..."

"Constructor allows us to easily load all our product data into their platform so we can personalize what’s shown to each shopper and improve the customer experience, while optimizing for our specific business KPIs.

We’re thrilled with the results we’ve seen, which validate this approach and reflect the impact of our digital transformation initiatives."

Utadi Murphy

General Manager, Digital & Ecommerce, Target AU

"A rare combination."

"Other vendors claimed that they had Al capabilities, but either it wasn't clear where the technology was applying their learnings, or Al was slated somewhere far down on the roadmap.

Al is inherent in the foundation of Constructor's technology and they demonstrated that they could align their tool with the business KPIs that I cared about. The Constructor team has a forward-thinking product, and they continue to deliver impressive customer service. That's a rare combination."

Bloomreach’s core search runs on legacy Solr/ElasticSearch technology with AI layered on top. This creates complexity, technical debt, and a heavy reliance on manual tuning — from synonym management to merchandising rules — just to maintain relevance. Many customers also report that Bloomreach’s personalization is limited to global ranking logic rather than true one-to-one experiences, and that onboarding can be slow and resource-intensive.

Constructor was built from the ground up with native AI, LLMs, and ML — no legacy baggage. Every click, browse, and add-to-cart instantly updates the experience for that specific shopper. Our automation handles repetitive tasks while keeping merchandisers in full control, freeing them to focus on strategy.

We also bring a perfect head-to-head track record — having never lost an A/B test to Bloomreach — and we back our promises with a Proof Schedule® that delivers projected ROI in just weeks. And unlike Bloomreach, our white-glove support is led by dedicated ecommerce experts who focus on your KPIs, not upselling additional products.

Request a demo to see our solution in action.
Yes, we offer a free Proof Schedule®. We know investing in AI is a significant decision, and we understand the need for assurance before commitment. This is a structured, no-risk engagement where we integrate a lightweight tracking pixel to evaluate your current search and product discovery performance. Over 2–4 weeks, we gather real-world data from your site, uncover missed opportunities, and identify measurable lifts you can expect when Constructor goes live.

By the end, you’ll have a business case built on your own data, including projections for revenue per visitor, conversion rate, and profit margin improvements. It’s proof you can take to your leadership team — and something Bloomreach doesn’t offer today. Learn more about our Proof Schedule.
Constructor supports fast integrations with platforms like Salesforce Commerce Cloud, Shopify Plus, commercetools, and custom stacks. Our onboarding process is streamlined, transparent, and merchant-friendly, so your team stays focused on strategy rather than technical firefighting. We’ve helped leading ecommerce brands and retailers get set up in 8 weeks or less—and prove ROI in just 4 weeks.
Our recommendations engine continuously learns from every shopper action — clicks, product views, add-to-carts, purchases — and adapts the experience instantly for that individual. The result is true 1:1 personalization across search, browse, recommendations, and other touchpoints, fully aligned with your business KPIs.

You can also guide the algorithm toward strategic goals — for example, boosting new arrivals, highlighting margin-rich products, or promoting seasonal items — without losing the AI’s ability to tailor the experience for each shopper.

In contrast, Bloomreach’s personalization often relies on global ranking logic, meaning all shoppers see the same adjustments, and true one-to-one experiences are limited.
Constructor’s PIA ensures high-intent shoppers don’t bounce at the finish line — delivering instant, trustworthy answers to their final product questions directly on your Product Detail Pages (PDPs). PIA analyzes your existing data — reviews, product specs, manuals, support content — and incorporates external sources to generate clear, context-aware answers in real time.
