What we do

From first idea to production at scale.

Twelve connected disciplines delivered by one accountable team, so strategy, engineering and governance never drift apart.

AI safeguards, SOPs & guardrails

Your people are already using AI. Make it safe, consistent and productive.

Without clear rules, everyday AI use quietly exposes confidential data, puts unverified content in front of customers and leaves leaders unable to answer the board. We give your organisation the policies and procedures to adopt AI with confidence, and set up technical guardrails such as Google Cloud Model Armor that screen every prompt and response automatically.

  • AI policy framework

    A concise, board-ready AI policy covering acceptable use, data classification, disclosure, accountability and escalation.

  • Role-based AI SOPs

    Step-by-step standard operating procedures for each team, from sales and finance to HR, operations and customer service, showing exactly how to use AI well.

  • Guardrail platform setup

    Design, deployment and configuration of Google Cloud Model Armor, Amazon Bedrock Guardrails, Azure AI Content Safety or open-source tools such as NVIDIA NeMo Guardrails, matched to your cloud and risk profile.

  • Prompt injection & jailbreak defence

    Automatic detection and blocking of malicious instructions hidden in user input, documents and web content before they reach your AI models.

  • Sensitive data protection

    Automatic detection and redaction of personal information, credentials and confidential data in prompts and responses, aligned to your data classification rules.

  • Content safety & topic controls

    Filters that keep AI responses on-brand and on-topic, blocking harmful, offensive or off-policy content and grounding answers in approved sources.

Who you’ll work with

Boardroom experience. Research-grade AI.

Our clients work directly with seasoned leaders who have sat on boards and run technology functions as CTOs, backed by PhD-qualified AI and machine learning researchers who keep us at the frontier.

Meet the team

Board directors & former CTOs

Our senior team has served on boards and led technology as CTOs and executives of established organisations. We understand governance, risk and accountability from the boardroom down, and we speak the language of your leadership team.

25+ years across industries

Decades of hands-on experience in technology, telecommunications, education, healthcare, construction and beyond means we start with your business realities, not a generic playbook.

PhD-led AI research & development

PhD-qualified AI and machine learning specialists run continuous R&D, testing new models, techniques and risks as they emerge, so the advice and systems you receive reflect what works today, not last year.

Client voices

Trusted for judgement as much as engineering.

They asked better questions about our business in the first week than most vendors do in a year. The roadmap they built is still guiding our investment decisions.
Chief Operating OfficerMid-market insurer
Calm, rigorous and refreshingly honest. When an idea was not going to work, they told us early and pointed us to the one that would.
VP of EngineeringLogistics software company
Our assistant went from pilot to two thousand daily users without a single security incident. The evaluation framework alone was worth the engagement.

FAQ

Questions, answered.

See all FAQs
Who will we actually be working with?

Senior people. Our leadership team includes former board directors and CTOs with more than 25 years of experience across technology, telecommunications, education, healthcare, construction and other sectors, supported by PhD-qualified AI and machine learning researchers. You will meet the people doing the work before the engagement starts.

Can you help us set rules for how our staff use AI tools?

Yes. Our AI Safeguards, SOPs & Guardrails service gives you a clear AI policy, role-based standard operating procedures, data-handling guardrails, an approved-tool register and staff training, and keeps them current as AI and regulation evolve.

Can you independently test and audit our AI systems?

Yes. Our AI Compliance, Testing & Auditing service tests AI you have built or bought for accuracy, fairness, robustness, privacy and security, assesses it against the regulations and standards that apply to you, and delivers a board-ready audit report with a practical remediation plan.

How do you keep up with how fast AI is changing?

Our PhD-qualified AI and machine learning researchers run continuous R&D: evaluating new models, techniques, risks and regulatory developments as they emerge. Those findings flow directly into our client recommendations, safeguards and delivery practices.

Will our data be used to train AI models?

Never without your explicit agreement. We use enterprise model agreements and self-hosted options that do not retain or train on your data.

How do you price engagements?

Fixed-price for well-defined phases, time-and-materials for exploratory work, or a monthly retainer for ongoing partnership. See our Pricing page for details.
