Recommend the right product to every customer.

A fully customizable quiz on your store that learns each visitor's goals, health, lifestyle, and diet, then matches them to the right products in your catalogue through a deterministic scoring algorithm. Not a decision tree, not persona-based. The algorithm is the differentiator.

Supplements and over-the-counter health is the live vertical, that's where the scoring engine has the deepest content layer (nutrient gaps, RDIs, ingredient interactions, dosing). Beauty and food are on the roadmap. The scoring architecture is portable across categories; the category-specific content layer is what we build out per vertical. If you're not in supplements yet, talk to us about timing.

It scores every product in your catalogue against the customer using more than 30 product attributes (ingredients, dosing, interactions, evidence, contraindications, synergies) and user signals spanning goals, sub-goals, conditions, lifestyle, and nutrient gaps inferred from a food-frequency questionnaire. Each pick comes with the specific reasons that produced it, not just an answer-to-tag match. See the methodology →

Goals first, then the signals underneath each one. A customer picks the goals that matter to them, spanning energy, sleep, gut health, hormonal balance, sports performance, healthy ageing and more. Each goal opens a follow-up that captures the specific signals behind it, so “gut health” becomes bloating, irregular habits, discomfort after dairy, and so on. That detail is what the scoring engine reads, alongside diet, lifestyle and biology.

General quiz tools match products to multiple-choice answers using tags or point accumulators. Blend runs deterministic scoring across every product in your catalogue, factoring in ingredient interactions, upper-limit safety, synergies, and nutrient gaps inferred from a food-frequency questionnaire. Same input always produces the same output, auditable, defensible, and shippable to brands in regulated categories. Every recommendation carries the reasons that produced it.

Upload your catalogue through our webapp. Shopify is supported with automatic sync, plus CSV and manual upload for any other source today. WooCommerce, BigCommerce, and other platforms are coming. Our team can help if your catalogue has anything unusual.

The engine includes a safety layer that runs on every recommendation: supplement–supplement interaction checks, medication conflict screens, upper-limit gating against EFSA tolerable intakes, and synergy pairing. Every flagged interaction or limit is traceable to a source rule, important if you operate in a regulated category.

On Pro and above, completely. Your brand, your colours, your domain, no “Powered by Blend” anywhere, as if you had a team of devs build it for you. Starter quizzes carry a small Blend badge. See the white-label options →

English today. Multi-language support, French and other major languages, is coming soon. The quiz text (questions, labels, CTAs) is fully customizable per brand, so when new languages land you can run a localised quiz per market.

Blend is fully GDPR-compliant under UK/EU regulations and the major US state privacy laws (CCPA, etc.). Brands can run quizzes globally, the platform serves customers in any country. Data residency requirements (EU, US, UK) are covered; talk to us during onboarding if you have specific compliance needs.

Pro and Enterprise plans include four analytics surfaces:

• User Analytics, who's taking your quiz: demographics, goals, conditions reported, diet, and more.
• Quiz Analytics, completion rates, drop-off points, common answer paths, conversion, and more.
• Product Analytics, which products get recommended most, product clicks, and add-to-cart once your store is connected. Purchase tracking is coming soon
• Market Analytics (coming soon), category-level trends across your customer base: what your audience cares about, where the gaps are.

Every view is brand-scoped. Cross-brand aggregates are anonymised and never expose individual customer data.

Yes. Most brands switch over in days, not weeks: we map your existing quiz logic into Blend's scoring engine, ingest your catalogue, and you keep your existing embed slot. Your old persona/tag rules become inputs to the algorithm.

Yes. You can adjust scoring weights, exclude product attributes, prioritise specific goal-to-product mappings, and configure brand-specific overrides during onboarding. The deterministic core stays, your tuning is layered on top.
