How it stacks

A single platform stack underneath every engagement.

The product layer
Your portfolio company's product
What customers see. What you've already built.
OneX · Built by us
Kaizou — execution platform on S+3 agile
Project management, structured planning gates, code quality discipline
OneX · Built by us
DouJou — AI infrastructure layer
Deploys inside your cloud. Customer data never leaves.
OneX · Network of providers
Six specialist capability providers
AI engineering, data, talent, content — pulled in per engagement

A pure augmentation engagement may use only Kaizou and a TTF squad. A full transformation typically pulls DouJou + Kaizou + two or three providers.

Built by us

Two platforms. Operational today.

Not roadmap items. Not vaporware. These are the platforms we deploy beneath every engagement — already in production across the portfolio.

OneX · AI Infrastructure

DouJou

AI that lives inside your cloud.

A 5-layer AI infrastructure stack that deploys directly inside a customer's own cloud environment — AWS, Azure, or GCP. Customer data never leaves their infrastructure. The AI runs on the customer's compute, against the customer's identity provider, governed by the customer's policies. Architecturally compliant with Schrems II, NIS2, and the EU AI Act on day one.

  • · VPC-deployable, single-tenant
  • · Tone-of-voice fidelity per customer
  • · Model serving + retrieval + ground-truth layers
  • · SOC 2 / ISO 27001 evidence architecture
  • · Used in production across OneX portfolio
OneX · Execution Platform

Kaizou

Faster execution on S+3 agile.

The unified workspace for engineering, product, and design teams that we operate across every OneX engagement. Built on S+3 agile — structured planning gates, definition-of-ready checkpoints, acceptance criteria before any work begins. Cycles instead of endless backlogs. Real-time co-editing of specs and tickets. Contextual time tracking that surfaces where throughput actually leaks.

  • · S+3 agile discipline by default
  • · Definition-of-ready gates pre-work
  • · Live spec + ticket co-editing
  • · Engineering health metrics surfaced
  • · In active production across portfolio
Network of capability providers

Six specialist providers. Pulled in per engagement.

Each provider is a focused capability we've worked with, vetted, and deploy through. Where OneX carries volume discounts with providers, we pass them through to portfolio companies at cost.

AI Engineering

BAJS.ai

RAG, chatbots, LLM integration.

Data scientists and AI engineers between France and India. Specialists in retrieval-augmented generation, cloud-to-AI migration, chatbot development, and production LLM integration. The team you deploy when DouJou needs to be customized for a specific portfolio company's data.

  • · RAG architecture
  • · Cloud-to-AI migration
  • · LLM integration
  • · Production chatbot deployment

Data & Annotation

Skysoft AI Labs

Data annotation, performance tracking.

Performance tracking, predictive analytics, custom dashboards. The provider we deploy when a portfolio company needs to build the data infrastructure that makes its AI work — and the analytics layer that proves it.

  • · Performance tracking
  • · Predictive analytics
  • · Custom dashboards
  • · Strategy optimization

Talent Engine

TTF

Talent sourcing, on the business timeline.

Flexible staffing and engineering squads. Time-and-material engagement, rapid deployment, customized teams. When a portfolio company needs delivery capacity beyond what its current team can produce, TTF is the engine.

  • · Flexible staffing
  • · Rapid deployment
  • · Customized engineering teams
  • · Time-and-material model

Data Cleaning & Training

MyDataMachine

Clean data. Tagged. Ready for AI.

Comprehensive data cleaning, tagging, annotation, and AI model training. The provider that prepares raw portfolio-company data into the kind of dataset DouJou can actually train against. Retail, security, satellite imagery specialism.

  • · Comprehensive data cleaning
  • · Tagging and annotation
  • · AI model training
  • · Scalable data services

Marketing Content

TechieButler

Marketing content at scale.

Marketing content creation for portfolio companies that need to ship a brand alongside the product. Blog content, landing pages, sales collateral, lifecycle email — the GTM content layer that most operating funds outsource and most consultancies bill for.

  • · Long-form content
  • · Sales collateral
  • · Lifecycle email
  • · Landing pages & funnels
Includes SaaSFlash — boutique video creation with human-in-the-loop, for portfolio companies that need short-form product videos and demo content shipped fast.
In conversation

We'll tell you what's missing.

A starting point, not a ceiling.

Not every portfolio company's needs map cleanly onto this toolkit. When something is missing — a regional operator, a specialist regulatory advisor, a domain we don't have credible bench in — we say so. Then we either source it through the broader operator network, or tell you it's not the right engagement for us.

The honest answer is more useful than the polished one.

How this looks in practice

Each engagement pulls a different combination.

Willow.co uses DouJou (AI infrastructure inside Willow's cloud) and Kaizou (execution discipline for the engineering augmentation team). The expansion-sales motion is run inside Willow's existing coach network — no provider needed there.

Sarouty uses DouJou (AI-powered property search and recommendation), Kaizou (execution discipline for the rebuild), TTF (engineering squad for the platform build), and MyDataMachine (cleaning and structuring the legacy Sarouty data plus building the regional property datasets for Algeria, Tunisia, Mauritania).

Visible (Verizon) predated DouJou as a productized platform — but used the exact architectural pattern that DouJou is the codification of. The human-AI hybrid service architecture (US Patent 12,056,644 B2) is what DouJou now ships as infrastructure, available on day one.

Bring us your engagement

The toolkit is real. The work is the rest.

Tools without operators are shelfware. The OneX engagement is the operators using the toolkit on a specific portfolio company's specific problem. If you have one of those — bring it.
