AI Personalization Engine Prices: Dynamic Yield, Nosto, Bloomreach, Klevu, Algolia, LimeSpot, and Rebuy by GMV Tier (2026)

**Dynamic Yield (Mastercard)** is the closest thing the industry has to an enterprise personalization OS. Acquired by Mastercard in 2022, it bundles on-site personalization, product recommendations, triggered messaging, experimentation, and a customer data layer into one platform. The product was built for retailers running tens of millions in GMV with multiple touchpoints (web, app, email, kiosk). The pricing reflects that — there is no self-serve tier, and the published guidance per https://www.dynamicyield.com/pricing is custom enterprise quotes scaled to GMV and impressions, typically landing between $60K and $300K per year.

**Nosto** is the mid-market workhorse. It started as a product recommendations engine for Shopify and has since grown into a full Commerce Experience Platform with onsite personalization, search, segmentation, and a recently launched GenAI category page builder. The pricing on https://www.nosto.com/pricing/ is the most transparent in the enterprise lane: Essential at $1,500/mo for stores under $1M GMV, Plus at $4,000/mo for $1-5M GMV, and Enterprise starting around $10K/mo for larger merchants.

**Bloomreach Discovery** is the search-and-merchandising arm of the broader Bloomreach platform (which also includes Engagement, the old Exponea CDP). Discovery is built on Loomi, Bloomreach's LLM layer, and competes head-on with Dynamic Yield for enterprise RFPs. Per https://www.bloomreach.com/en/products/discovery the pricing is custom enterprise — typically $60K to $250K per year depending on catalog size, query volume, and modules. **Klevu** narrows the focus to AI search and category merchandising, with transparent tiers from $99/mo (https://www.klevu.com/pricing/) up to custom Plus contracts.

**Algolia AI** is the developer-first option. The core product is a hosted search API with NeuralSearch (vector + keyword hybrid), Dynamic Re-Ranking, and Recommend modules. Pricing is usage-based per https://www.algolia.com/pricing: Free up to 10K requests and 1K records, Build at $0.50 per 1K search requests plus $0.40 per 1K records, and a custom Grow tier. The AI Search add-on (NeuralSearch) is roughly 3x the base search cost.

**LimeSpot** and **Rebuy** are the Shopify-native specialists. LimeSpot focuses on product recommendations and bundles, priced per https://www.limespot.com/pricing at $18/mo plus 0.5% of revenue (Essentials), $48/mo plus 0.5% (Growth), or custom (Premium). Rebuy specializes in funnel personalization — Smart Cart, post-purchase upsells, and AI-driven recommendations — with order-volume tiers per https://www.rebuyengine.com/pricing: $99/mo Starter (≤2,500 orders), $249/mo Scale (≤7,500), $499/mo Pro (≤15K), and $749+/mo Enterprise.

**Dynamic Yield** ships a JavaScript snippet plus server-side APIs and supports Shopify Plus, Salesforce Commerce Cloud, Adobe Commerce, BigCommerce, and custom stacks. The trade-off: deep capability requires real implementation effort. Most enterprise deployments take 8-16 weeks and involve a tagging plan, data feed configuration, and audience setup. Mastercard's stewardship has stabilized the roadmap and pushed harder into financial services partnerships, but the core integration footprint is unchanged from the pre-acquisition era documented at https://www.dynamicyield.com/pricing.

**Nosto** is the easiest enterprise-grade install on this list. The Shopify app deploys in hours, BigCommerce and Magento in days, and custom stacks via SDK in 2-4 weeks. Nosto's product catalog ingestion handles up to ~5M SKUs cleanly, and the Plus tier unlocks dedicated CSM and integration support. **Bloomreach Discovery** is the opposite — implementations take 12-20 weeks, require a structured catalog feed, and typically involve a partner agency. The payoff is depth: Loomi-ranked search with category-level merchandising rules that survive complex catalogs (think 500K+ SKU electronics or apparel retailers).

**Klevu** sits between Nosto and Bloomreach on install complexity. Shopify and BigCommerce stores get a near-turnkey install; Magento and custom stacks need 4-6 weeks. The Suite tier at $449/mo per https://www.klevu.com/pricing/ adds full category merchandising and personalized recommendations, while Plus (custom) unlocks dedicated environment and SSO. **Algolia** is the only engine here built API-first. You get a hosted index, REST and SDK access in every major language, and Shopify/Magento connectors. Engineering teams love it because they own the relevance tuning end-to-end.

**LimeSpot** and **Rebuy** are Shopify-only and install in minutes. LimeSpot drops in via the Shopify app store, auto-detects your product catalog, and starts recommending within hours. The 0.5% revenue cut applies above a threshold per https://www.limespot.com/pricing, so true cost scales with sales. **Rebuy** focuses on the cart, checkout, and post-purchase flows — Smart Cart replaces your native cart drawer, and AI rules drive upsells and bundles. Both lean on Shopify's metafields and Liquid templates, so non-Shopify merchants are out of scope.

Architecturally, the meaningful split is SaaS-only versus API-first. Every vendor here is SaaS-hosted — none offer self-hosting — but **Algolia** and **Bloomreach** publish enough API surface to run as headless services behind your own front-end. **Dynamic Yield**, **Nosto**, **Klevu**, **LimeSpot**, and **Rebuy** lean on injected scripts and platform-specific apps, which is faster to deploy but couples you to their rendering layer. If your team is migrating to a composable commerce architecture (Hydrogen, Next Commerce, commercetools), that distinction matters.

Let's run the numbers at four GMV bands: $500K, $5M, $25M, and $100M annual revenue. At $500K GMV, **Dynamic Yield** and **Bloomreach Discovery** are simply not in the conversation — their enterprise floors near $60K/yr per https://www.dynamicyield.com/pricing and https://www.bloomreach.com/en/products/discovery would consume 12% of revenue. **Nosto** Essential at $1,500/mo ($18K/yr) is still steep at 3.6% of GMV. **Klevu** Smart at $99/mo (https://www.klevu.com/pricing/), **LimeSpot** Essentials at $18/mo + 0.5% = $2,716/yr, and **Rebuy** Starter at $99/mo are the realistic options. **Algolia** Free tier handles small stores until query volume crosses 10K/month.

At $5M GMV, the field opens up. **Nosto** Plus at $4,000/mo ($48K/yr) is roughly 1% of GMV — the right ballpark for a mid-market personalization budget. **Klevu** Suite at $449/mo ($5,388/yr) is essentially free at this scale if you only need search and recs. **Algolia** Build pricing per https://www.algolia.com/pricing — at, say, 5M search requests/month and 50K records — works out to $2,500 search + $20 records = ~$30K/yr; add NeuralSearch (~3x) and you're at ~$90K/yr. **Rebuy** Pro at $499/mo ($6K/yr) covers up to 15K orders, fitting a $5M store with $50 AOV.

At $25M GMV, the enterprise vendors enter the picture. **Dynamic Yield** quotes typically land around $120K-180K/yr (~0.5-0.7% of GMV) per published RFP guidance. **Bloomreach Discovery** quotes are similar. **Nosto** Enterprise tier (~$10K-15K/mo, or $120K-180K/yr) per https://www.nosto.com/pricing/ is competitive on absolute cost but lighter on experimentation tooling. **Algolia** at this volume with NeuralSearch crosses into the custom Grow tier, typically $150K-250K/yr. **Rebuy** Enterprise at $749+/mo is genuinely cheap at this band, but only solves checkout and funnel — not full-site personalization.

At $100M GMV, **Dynamic Yield** and **Bloomreach Discovery** typically land between $200K and $300K+/yr, which is 0.2-0.3% of GMV — a defensible number for the capability you get. **Nosto** Enterprise at this scale negotiates closer to $250K/yr with full SSO, dedicated CSM, and contractual SLAs. **Algolia** Grow with NeuralSearch and Recommend can run $300K-500K/yr for very high query volumes. The mid-market and SMB engines (Klevu Suite, LimeSpot, Rebuy) are not the right fit at this band — you outgrow their data models and merch tooling.

The lesson — and it's the most important one in this article — is that vendor pricing models drive total cost more than headline rates. **LimeSpot's** 0.5% revenue share looks tiny, but at $25M GMV it's $125K/yr on top of base. **Algolia's** usage pricing is great until NeuralSearch triples your bill. **Rebuy's** order tiers are honest but lock you into a per-order economic model. **Nosto's** GMV bands are the most predictable across growth. **Dynamic Yield** and **Bloomreach** are predictable too — once you sign the multi-year contract — but the floor is too high for anyone under $10M GMV.

If you are a $1-5M GMV Shopify merchant who wants "set it and forget it" personalization, **Nosto** Plus or **Rebuy** Pro are the right starting points depending on whether you want site-wide recs or funnel optimization. Nosto's onsite personalization and product recs handle category pages, PDPs, and overlays cleanly. Rebuy's Smart Cart and post-purchase flows typically lift AOV 8-15% and pay for themselves inside a quarter — at $499/mo per https://www.rebuyengine.com/pricing the payback math is straightforward. Many merchants run both: Nosto for browse, Rebuy for cart.

If you are a $5-25M GMV Shopify Plus or BigCommerce merchant with engineering bandwidth, **Algolia** with NeuralSearch is the technical winner. You get full control over relevance tuning, the API surface integrates cleanly with any front-end, and Recommend (Algolia's recs module) handles personalized product blocks. Budget $80K-200K/yr depending on query volume. If you do not have engineering bandwidth, **Klevu** Suite at $449/mo (https://www.klevu.com/pricing/) delivers 80% of the same capability with zero engineering work.

If you are a $25M+ GMV brand with a complex catalog (electronics, apparel, B2B distribution), **Bloomreach Discovery** is the strongest fit. Loomi's semantic ranking and the platform's merch tooling handle the long tail in ways Dynamic Yield doesn't match for pure search. **Dynamic Yield** wins when experimentation and audience-driven personalization across web/app/email are the priority — its experimentation framework is the deepest on the list. Both will quote $120K-250K/yr, so the decision is feature-fit, not price.

If you are sub-$1M GMV, do not buy enterprise personalization. The math doesn't work. **LimeSpot** Essentials at $18/mo + 0.5% revenue per https://www.limespot.com/pricing, **Klevu** Search Smart at $99/mo, **Rebuy** Starter at $99/mo, or **Algolia** Free are all viable. The mistake at this stage is paying for a platform you cannot fully operate. Get to $1M in revenue with cheap, focused tools, then graduate to Nosto or Klevu Suite when your conversion data justifies the investment.

One opinionated call: if you are a marketing-led team that wants the personalization engine to do real work without an in-house data scientist, **Nosto** is the most honest choice in the $1-25M GMV band. The product is mature, the pricing on https://www.nosto.com/pricing/ is published, and the integration is fast. Where Nosto is weaker is experimentation depth — if you run a serious A/B program with dozens of concurrent tests, Dynamic Yield is worth the jump. For most merchants, Nosto's lift is enough.

Enterprise procurement teams care about three things: SOC 2 Type II, SSO/SAML, and data residency. **Dynamic Yield** under Mastercard has the strongest posture of the group — SOC 2 Type II, ISO 27001, PCI DSS Level 1 (inherited from Mastercard infrastructure), and US/EU data residency. SSO/SAML is standard on every enterprise contract per https://www.dynamicyield.com/pricing. **Bloomreach** matches on SOC 2 and ISO 27001 and adds APAC data residency, which matters if you sell into Australia, Japan, or Singapore at scale.

**Nosto** holds SOC 2 Type II and is GDPR-compliant with EU data residency available on Plus and Enterprise tiers per https://www.nosto.com/pricing/. SSO/SAML is gated to Plus and above — a reasonable trade-off, but worth noting if your procurement team requires SSO at every tier. **Klevu** SOC 2 Type II and EU residency on Suite and Plus per https://www.klevu.com/pricing/. SSO is Suite-tier and above.

**Algolia** has the most flexible posture on the list. SOC 2 Type II, ISO 27001, HIPAA-eligible on Grow, and configurable data residency (US, EU, APAC, or custom) per https://www.algolia.com/pricing. SSO/SAML is Grow-tier. If you have a security team that demands HIPAA or specific regional clusters, Algolia is the only vendor on this list that ships them as standard configuration options.

**LimeSpot** and **Rebuy** are the weakest on security tooling, which is unsurprising given their SMB focus. LimeSpot has SOC 2 Type II but only US data residency and SSO/SAML on Premium only per https://www.limespot.com/pricing. **Rebuy** has SOC 2 Type II and gates SSO to the Enterprise tier per https://www.rebuyengine.com/pricing. For most Shopify SMBs this is fine. For a brand inside a public-company portfolio or anyone selling into EU consumers with strict GDPR posture, these gaps need a hard conversation in vendor selection.

A note on AI training data: every vendor on this list trains its models on your store's behavioral data, which is the entire point. What varies is whether they pool that data across customers. **Dynamic Yield**, **Bloomreach**, and **Algolia** explicitly isolate customer data and do not cross-train. **Nosto** does pool anonymized behavioral signals for its baseline recommendation models — disclosed in their DPA. **Rebuy** and **LimeSpot** are similar. If "my behavioral data feeds my competitor's recs" is a non-starter for your legal team, surface it in the RFP before signing.

"AI personalization" is the most abused phrase in commerce. Let's get specific. **Dynamic Yield** runs deep-learning recommendation models (collaborative filtering plus content-based embeddings), audience prediction models, and a fully managed experimentation engine that handles multi-armed bandits as well as standard A/B tests. The platform was AI-first before the LLM wave and remains the most sophisticated experimentation toolset on the list per https://www.dynamicyield.com/pricing.

**Bloomreach Discovery** built Loomi, an LLM layer that powers semantic search, GenAI-assisted merchandising rules, and product copy generation. The headline differentiator is semantic search ranking — Loomi understands intent at a level the keyword-plus-vector hybrids don't match. **Nosto** added GenAI category page generation in late 2025 and uses computer vision (Visual AI) for image-based product matching. **Klevu** is built on self-learning search models that adapt query understanding from clickstream data without manual tuning, per https://www.klevu.com/pricing/.

**Algolia** ships NeuralSearch (a hybrid vector + keyword search), Dynamic Re-Ranking (clickstream-driven relevance tuning), and the Recommend module (collaborative filtering recs). NeuralSearch is the AI Search add-on that roughly triples the base search cost per https://www.algolia.com/pricing. The trade-off is honest — you can buy classic Algolia and skip the AI premium, or you can pay 3x for vector understanding. Many merchants start without it and add NeuralSearch once they have query data to justify the lift.

**LimeSpot** uses RFM segmentation (recency, frequency, monetary) plus collaborative filtering for recommendations and recently added a visual similarity module. **Rebuy** describes its engine as "AI-driven" but the actual models are simpler — rules-based merchandising layered with collaborative filtering for upsells. That's not a knock; the funnel-level personalization Rebuy is solving for (cart upsells, post-purchase recs) does not need a transformer model, and the simpler stack is part of why the pricing on https://www.rebuyengine.com/pricing stays low.

The pragmatic read: if you want true semantic understanding of catalog and query, **Bloomreach Discovery** and **Algolia NeuralSearch** are the leaders. If you want deep behavioral modeling and experimentation, **Dynamic Yield** is the leader. If you want "good enough AI recs" that work out of the box without thinking about it, **Nosto**, **Klevu**, and **Rebuy** are honest options. Do not pay enterprise prices for "AI" that is collaborative filtering with a paint job — verify the actual model architecture in the RFP.

Every vendor on this list has line items the pricing page doesn't mention. **Dynamic Yield** contracts typically include implementation fees ($25K-75K) and assume a multi-year commitment for the headline rate. Single-year contracts run 30-40% higher. **Bloomreach Discovery** is similar — expect a $40K-100K implementation fee and a 24-36 month term. Annual price escalators of 5-7% are standard in both contracts and need to be capped in negotiation.

**Nosto** is more honest. The Essential and Plus tiers per https://www.nosto.com/pricing/ are month-to-month or annual with no implementation fee for Shopify, BigCommerce, or Magento. Custom stacks carry a one-time integration fee ($10K-25K). Enterprise contracts have 5% annual escalators unless capped. **Klevu** is similar across Smart, Smart + Recs, and Suite — no implementation fees on Shopify/BigCommerce, custom integration fees on Magento. Plus tier contracts run 12-24 months.

**Algolia's** usage pricing per https://www.algolia.com/pricing is the most exposed to surprise bills. Search requests are easy to estimate, but record counts scale with catalog freshness — if you re-index your full catalog hourly, each re-index counts. Stores running heavy faceted search (apparel, electronics) regularly hit 5-10x their estimated query volume. NeuralSearch adds a base subscription on top of usage. Budget 30-40% buffer above estimated usage for year one.

**LimeSpot's** 0.5% revenue share is the most controversial line item in this comparison. At $5M GMV, that's $25K/yr on top of the $48/mo base — competitive at that scale. At $25M GMV, it's $125K/yr — uncompetitive. Per https://www.limespot.com/pricing the revenue share is on attributed revenue (transactions that touched a LimeSpot recommendation), which is generous to LimeSpot's attribution logic. Read the attribution methodology before signing.

**Rebuy's** order tiers per https://www.rebuyengine.com/pricing are honest, but overage pricing is steep — exceed your order band and you pay per-order until you upgrade. A store on Scale ($249/mo, ≤7,500 orders) that hits 10K orders pays the overage rate, which can equal the Pro tier cost without unlocking Pro features. Set up volume monitoring early. Across all vendors: insist on a price cap, an exit clause, and a data export commitment in the contract — every vendor on this list will provide them if you ask.

Take a real-shaped merchant: $15M GMV, 80K orders/year, $187 AOV, 25K SKUs, 4M monthly site sessions, and 6M monthly search queries. Here's what each vendor actually costs at that profile. **Dynamic Yield** quotes typically land at $140K-180K/yr at this scale per https://www.dynamicyield.com/pricing, plus a $40K implementation. Year one: $180K-220K. **Bloomreach Discovery** is similar: $130K-170K/yr plus $50K implementation. Year one: $180K-220K.

**Nosto** Enterprise at this profile typically negotiates to $9K-12K/mo ($108K-144K/yr) per https://www.nosto.com/pricing/ with no implementation fee on Shopify Plus. Year one: $108K-144K. **Algolia** at 6M search requests/month is $3K/mo base search ($36K/yr); add NeuralSearch (~3x) and Recommend, and you're at ~$120K-150K/yr. Year one: $120K-150K. **Klevu** Suite handles this volume at $449/mo plus a custom uplift for query volume — roughly $15K-20K/yr total. Year one: $15K-20K.

**Rebuy** Pro at 80K orders requires Enterprise tier — $749+/mo, typically negotiated to $1,200-1,800/mo at this volume ($14K-22K/yr) per https://www.rebuyengine.com/pricing. Year one: $14K-22K. **LimeSpot** Growth at $48/mo + 0.5% of $15M GMV = $75,576/yr. Year one: $75K-80K. The headline insight: at $15M GMV, the spread between cheapest viable solution (Klevu Suite at ~$18K/yr) and most expensive (Dynamic Yield at ~$220K/yr) is 12x.

That spread is not waste. Klevu Suite gives you search and product recommendations — full stop. Dynamic Yield gives you those plus full-site experimentation, audience modeling, triggered messaging, and a CDP layer. The right question is not "which is cheapest" but "which capabilities will I actually use in year one." Most merchants at $15M GMV use 30-40% of Dynamic Yield's capability, which makes Nosto Enterprise (at $120K-140K) the better-value mid-point if you need more than search but less than full experimentation.

The cleanest TCO move at $15M GMV in 2026: pair **Klevu** Suite ($18K/yr) or **Algolia** NeuralSearch ($120K/yr if you have engineering) for search, plus **Rebuy** Pro/Enterprise ($15K-20K/yr) for funnel personalization, plus **Nosto** Essential ($18K/yr) or skip onsite personalization entirely. Total stack cost: $50K-160K/yr depending on configuration, versus $180K-220K for a single Dynamic Yield contract. The stack approach gives you better tools per dollar — at the cost of three vendor relationships instead of one.
