Products
One approach, three layers
A platform for building agents. Applied products that put those agents to work on language-heavy jobs. And ventures — whole businesses designed from day one to run with near-zero headcount on the same foundations.
Platform
The engine everything else is built on.
AI Agentic Workbench
An enterprise platform for building, deploying and scaling AI agent workflows through a visual interface — no code required, full code welcome.
- Drag-and-drop visual workflow builder with a pre-built block library
- Deploy any workflow as a production API with auth and scaling built in
- Provider-agnostic: OpenAI, Anthropic Claude, Google Gemini and local models
- Intelligent caching cuts external API costs by up to 60%
Applied AI
Agents applied to language-heavy work — with structured output and a human making the decision.
STAR Interviewer
An AI-powered interview platform that scales hiring capacity without scaling interviewer hours. Structured STAR interviews, automatic transcription and scoring, authenticity detection — with humans making every final decision.

Analyse and evaluate large volumes of proposals by quality, theme and objectives. Filter out what doesn't meet your criteria and focus your time on the most promising candidates.
Learn more →Ventures
Self-running businesses we've built and operate: AI-agentic provisioning, billing and support, so they scale without scaling a team.
SignPlus
Turns signage companies into digital services resellers. Branded email, a domain and a lead-ready website, sold at the signage counter and provisioned the same day — with recurring revenue for the signage partner.

Display, made human. A web admin and a low-cost streaming stick turn any TV into a screen that updates from anywhere — for cafés and offices, for families, and for care homes.

Built to run without a team behind it
Every product, from the Workbench to a care-home screen, follows the same three rules.
Agentic by design
Provisioning, monitoring, billing and first-line support are done by agents. Marginal cost per customer stays near zero, so each product scales without proportional headcount.
Humans make the final call
AI structures, scores and summarises. A person reviews, overrides and decides. No algorithmic black boxes, and every evaluation is auditable.
Production-grade foundations
Multi-tenant isolation, role-based access, encrypted storage and audit trails come as standard. Provider-agnostic, so no vendor lock-in.
