Interfaces that
respond to who's
using them.

Same component tree, three rendered surfaces. Power users get density, newcomers get scaffolding, everyone else gets the right next step. Personalization that's measured against business outcome — not engagement vanity.

Where 'one UI for everyone' breaks down

The patterns we see in commerce, SaaS, and content products — and the design and ML shape of the answer.

01

Average UX is nobody's UX

The interface designed for everyone is calibrated for no one. Adaptive UX makes the surface fit the person without making the person fit the surface.

02

Engagement isn't the metric

Time-on-app and CTR can be gamed. We measure personalization against task success, conversion, and long-term retention — the metrics the business actually owns.

03

Personalization without dark patterns

Consent-first, explainable, and reversible. The user can see why they're seeing this variant, and switch off if they want. Trust compounds.

What we ship, by the person on the hook for the surface

persona

VP Product

Pain
Activation is flat. Power users want density we can't ship without breaking newcomers.
What we ship
A variant tree across onboarding, hero, and IA — with a personalization core that picks the surface per user, measured against activation and retention.
persona

Head of Growth

Pain
Lifecycle emails are 1990s. We need cohesive personalization across web, push, and inbox.
What we ship
One personalization model behind every surface — same segments, same variant tree, audited consent. No more channel-by-channel duct tape.

Design Director

Pain
Engineering ships variants we never approved. Accessibility regresses each release.
What we ship
Variant slots that designers own. WCAG-checked at the slot level. A clear contract between design system and personalization core.
persona

Privacy & Trust Lead

Pain
We can't audit what variant a user saw, when, why. Regulators are noticing.
What we ship
Per-render trace ledger, consent-aware resolver that respects strict regions by default, and a 'why this variant' explanation at every surface.

Six capabilities. One personalization core.

The variant tree is a contract between design and engineering. The resolver is a contract between product and ML.

Variant Tree

Per-component variant slots designers own and engineering ships safely.

  • Slot-level variants
  • WCAG-checked at slot
  • Same tree across web/mobile/email

Segment-of-One Resolver

Picks the right variant per user, in <30ms, at the edge.

  • Edge or origin
  • Cacheable by segment
  • Explainable decisions

Identity & Consent

First-party identity graph that respects consent by default.

  • Anonymous → known stitch
  • Per-region consent rules
  • No third-party cookies needed

Experimentation

Bandits, A/B, holdouts, and uplift — chosen per slot.

  • Exploration vs. exploitation
  • Sequential testing
  • True holdout always reserved

Lifecycle & Inbox

Personalization that follows the user across every channel.

  • Email · push · in-app
  • Same segments everywhere
  • Frequency capping baked in

Trace & Explainability

Every render explained. Every variant rolled-back-able.

  • Per-render audit ledger
  • 'Why this' panel for the user
  • One-click revert per slot

Signal → resolver → variant → render

Five lanes, one feedback loop. The resolver is the seam between your data and your design system.

Lane 01 · Signal & Identity

Events, session, profile, live state — stitched into a first-party identity graph that respects per-region consent.

Lane 02 · Personalization Core

Derive features → score → policy → assign experiment. Edge-or-origin. <30ms. Cacheable by segment.

Lane 03 · Variant Tree

Per-component slots designers own. WCAG-checked. Reverts at the slot, not the page.

Lane 04 · Render & Loop

Web, mobile, email — same tree. Telemetry feeds the eval harness; a true holdout is always reserved.

From audit to multi-surface in roughly 10 weeks

Each phase ends with something live, measured, and reversible.

What we get asked on the discovery call

We design against it. Every variant has a 'why this' explanation visible to the user, every render is audited, and the eval rubric weights long-term retention over short-term engagement. If a variant lifts CTR but tanks 30-day retention, it gets cut.

First-party only by design. The identity graph stitches anonymous → known → signed-in via your own events, and the resolver runs against your CDP / warehouse. No third-party cookies needed; consent rules are enforced per region (GDPR strict in EEA by default).

No. The variant tree is additive — slots wrap existing components. Your design system stays the source of truth; we add the seam where variants live and the resolver call.

WCAG checks run at the slot level on every variant before it's eligible to ship. Designers approve variant slots; engineering can't ship one that fails the contrast or focus-order checks.

Consent-aware resolver respects strict regions by default — a user in EEA will not see personalized variants that depend on consent.marketing unless they've granted it. Audit trail proves it.

A pilot on one surface runs ₹40L–90L over 8–12 weeks. Multi-surface expansion (mobile, email, inbox) typically adds ₹20–40L per channel. Resolver and eval pipeline are reusable across surfaces.
