Build agents that build relationships.

A senior AI engineering team for consumer and B2B2C product teams that need shipped relational agents, not slideware. We design, build, and operate companions, characters, avatars, NPCs, and brand voices on the Sonzai relationship layer.

A senior team, not a vendor on the side.

We work like a forward-deployed product and engineering team. You get founder attention, senior AI architecture, production code, and an operating loop that keeps improving after launch.

What we build

Three disciplines. One production system.

01

Relational agents

Companions, characters, NPCs — built around your product.

We design and ship the agent itself — the personality, the memory shapes, the relationship arc — and wire it into the surface your users already see. Companion app, character platform, brand experience, game.

  • Companion apps with persistent memory, personality, and mood
  • Characters and NPCs that remember every player and grow with the world
  • Brand voices and concierge agents that own the consumer-facing surface

02

Relationship Layer

State that compounds, per user.

Most AI resets every session. Sonzai gives every agent persistent memory, personality, mood, and relationship state — so the agent gets more personal with every turn, not blanker.

  • Persistent per-user memory, mood, personality, and relationship state
  • Model-agnostic context assembly under a 200ms retrieval target
  • Lower model spend by moving cognitive load into the runtime

03

Custom surfaces

Your brand, your stack, your platform.

When the agent needs to live somewhere specific — your app, a white-label platform, a game client, a partner's product — we build the surface and the integrations around it.

  • White-label consumer apps and B2B2C platform surfaces
  • Game-side integrations, web, mobile, and voice front-ends
  • Auth, CRM, commerce, comms, and platform-API wiring

How we work

Architecture, then code, then operating cadence.

The first version is intentionally focused. We prove the relational surface with real users, then turn every conversation into better memory, sharper personality, and a more useful agent.

01

Discovery

We map the agent, the relationship arc, the users it serves, and the metric the first relational surface will own.

1-2 weeks

02

Architecture

We design the memory shapes, personality contract, mood model, escalation paths, and safety guardrails.

1-2 weeks

03

Build

We ship a focused first version with real users, validate the relational loop, then expand only where the data supports it.

4-12 weeks

04

Evolve

We monitor, tune, and keep improving the agent as it learns each user — compounding personalization across the base.

Examples

Relational agents, shaped by the surface they live in.

Every product is different. These examples show the shape of bespoke relational agents we can design, launch, and operate with you.
