What Real Users Say on G2

The Only Modern, Differentiated Product Discovery Platform

Why Constructor Wins Where Algolia Falls Short On G2

Algolia customers frequently mention slow, unresponsive support, heavy manual setup, and limited personalization. Constructor customers highlight fast time to value, white-glove support, and personalization that adapts instantly to every shopper.

Constructor is consistently rated higher across every key satisfaction metric — from ease of use to quality of support –  and we back it up with a perfect A/B testing track record against Algolia.

Enterprise Ecommerce Search & Discovery

Personalized Discovery, Optimized By Advanced AI Reasoning

Enterprise ecommerce search and product discovery is the only thing we do

Constructor delivers the best business results for the retail industry thanks to a truly different approach.

It all starts with the reasoning engine being tuned to your website specifically and ingesting the full clickstream of your website. That data is then augmented with petabytes of verified clickstream from hundreds of customers — enabling Constructor to predict which product a shopper is most likely to buy, not just which product appears most “relevant.”

The result is delivering the right products to the right person at the right time in the right context - across any discovery point,  onsite or offsite.

That foundation lets us understand shopper intent on a deeper level, respond in real time, and turn every search into measurable business growth. With Constructor, you’re able to:

  • Deliver personalized results in real time across search, browse, recommendations, and every touchpoint.
  • Upgrade your discovery experience with proven, leading innovations — like adaptive interfaces and AI agents — without rebuilding your tech stack.
  • Drive measurable revenue growth with AI-powered ranking that learns continuously from real shopper behavior and product data.
  • Stay in control with intuitive merchandising tools that make curation, promotions, and overrides simple, transparent, and fast.

How Petco drove a 13% lift in ecommerce conversions with Constructor

'The thing we liked about Constructor was that not only was it real AI, specifically made for our industry, but that their AI is incredibly transparent. None of it is black box – so we don't have to guess what it's doing or why – and when we have questions, the Constructor team is always happy to talk us through it. We evaluated every vendor on the market, and Constructor was just different. The system is easy to use, the team is motivated and delightful to work with, and most importantly, it paid for itself plus the cost of switching in less than a year after we implemented it.'

FAQs

  • Constructor puts a beacon directly on your site to ingest the full behavioral clickstream of your shoppers (every click, scroll, add-to-cart, and purchase) from your ecommerce site. The system is able to reason by augmenting the wealth of signals from your ecommerce site specifically with petabytes of anonymized, real, first-party and zero-party data across hundreds of other customers. The AI-driven results are ultimately a balance between elements including conversion rate, margin, diversity, and brand constraints, learning from real shopper behavior rather than abstract relevance scores. 

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

  • Yes, we offer a free Proof Schedule® for enterprise companies. We know investing in technology 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. Learn more about our Proof Schedule.

  • Constructor partners with the world’s top retail consultants, systems integrators, and technology platforms like Shopify, AWS, and Braze. We provide a variety of integration approaches to make the integration process as fast and simple as possible. Learn more about our partner ecosystem.

  • 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.

Are you leaving revenue on the table with Algolia?

Where Algolia goes broad, we go deep. When it comes to the quality of our solution, our results are based completely on actual conversion from real data.
