AI Personalization Engine Development
We build real-time content and offer personalization layers, recommendation engines, and segmentation models for marketing-AI products. Low-latency inference, honest data controls, architected to scale.
What we build
Real-time content personalization
Per-visitor page, hero, and email-block personalization decided at request time, with a control path that falls back to the default experience the instant the model is uncertain.
Offer decision engines
A mix of rules and a model that picks the offer, discount, or nudge most likely to convert a given user, with eligibility limits and margin floors built in.
Segmentation & audience models
Behavioural and lifecycle segment models, lookalike scoring, and audience builders that stay in sync with the traits your downstream tools already trust.
Recommendation systems
Collaborative-filtering and embedding-based recommenders for content, products, and articles, with cold-start handling and diversity/recency controls.
Real-time inference & feature serving
A feature store and low-latency serving layer that resolves a visitor’s signals and returns a decision inside the latency budget a page render allows.
A/B/n testing & lift measurement
Experiment assignment, holdout groups, and incremental-lift reporting so personalization is measured against a real baseline instead of assumed to be working.

Marketing data that resists wishful thinking
Reference architecture
- Event & Profile Ingest
- Feature Store
- Segmentation + Decisioning
- Real-time Inference API
- Content / Offer Delivery
- Experiment & Lift Tracking
A typical AI personalization system: events and profile data land in a feature store that a decision layer reads at request time; the inference API returns a personalized content or offer decision inside the page’s latency budget, and every impression flows into experiment tracking so lift is measured against a holdout.

Which engagement fits
Project Build
For standing up the core engine: feature store, decisioning, real-time inference, and experiment tracking. Delivered in a focused 8–14 week scope.
Explore Project BuildEmbedded Squad
For evolving models, adding recommendation features, and tuning lift over time. A dedicated team that ships alongside yours as the product grows.
Explore Embedded SquadTech Audit
For assessing an existing personalization stack: a 5-day diagnostic of latency, data plumbing, model health, and whether the lift is measured at all.

| Standard | Status | What we ship |
|---|---|---|
| GDPR / UK GDPR | Compliant | Lawful-basis handling, data subject rights, and retention controls across the profile store and feature pipeline. See /compliance/gdpr. |
| CCPA / CPRA | Compliant | Consumer opt-out and “do not sell/share” signals wired through segmentation and decisioning so an opted-out visitor is served the default experience everywhere. |
| Consent & preference enforcement | Compliant | Consent state (via your CMP) gates which signals feed the model. Profiling stops the moment consent is withdrawn, not on the next batch. |
| Automated decision-making fairness | In progress | For offer and eligibility decisions we build per-decision explainability and recommend a bias review of the segment features. The engineering is ours, the policy call is yours. |

Attribution, personalisation, and scale in production
Marketing AI products live or die on data quality, latency, and whether the numbers hold up under real traffic. We build for the dashboard that a CMO opens at 8am on Monday.
Frequently asked questions
We treat latency as a hard budget, not an aspiration. Signals are resolved from a feature store and served through a low-latency inference API (typically backed by Redis or DynamoDB), with a control path that returns the default experience the moment a decision would blow the budget. The visitor never waits on the model.
