Reducing document review time by 40% through a fractional CAIO engagement and AI governance framework for a Newcastle-based law firm.
Hartley Legal Group, a Newcastle-based law firm, achieved 40 percent faster document review through an AI governance framework implemented by ajairu.ai. The engagement delivered a clear AI policy, compliance framework, and trained the firm's team to enforce it independently, all at a fixed price.
Hartley Legal Group is a commercial law firm based in Newcastle, providing corporate, employment, and property law services to businesses across the North East. The firm had been exploring AI tools to speed up document review and legal research, but as a regulated practice governed by the Solicitors Regulation Authority, they needed a solid governance framework before deploying AI in client-facing work. David Nuttall, a partner at the firm, had been tasked with leading the AI initiative but needed senior strategic and governance support to do it safely.
Hartley Legal Group faced a familiar dilemma for law firms. Their junior lawyers and paralegals were spending hours on document review, contract analysis, and due diligence work that AI could accelerate. But the risks of deploying AI without governance were significant: client confidentiality breaches, data protection violations under GDPR, SRA compliance failures, and the potential for AI-generated errors reaching client work without oversight. David knew they needed AI, but he also knew they needed to do it right.
The key challenges were:
The engagement started with a fractional CAIO arrangement, giving Hartley Legal Group a senior AI leader on a part-time basis. The fractional CAIO role was designed to provide strategic direction, governance oversight, and vendor selection support without the cost of a full-time executive. This was combined with an AI governance engagement to build the regulatory and compliance framework the firm needed before deploying any AI tools.
The solution was delivered in three phases:
The fractional CAIO continued to provide ongoing oversight after the initial implementation, reviewing compliance on a monthly basis, advising on new AI use cases as they arose, and reporting to the partnership board on AI adoption and risk management.
After the system went live, document review time dropped by 40%. Junior lawyers who previously spent 15-20 hours per week on routine contract analysis and due diligence were able to focus on higher-value legal work. The AI tool handles first-pass review, clause identification, and risk flagging, while qualified lawyers review the output and make final judgements. The human review checkpoint ensures accuracy and accountability while still delivering significant time savings.
The governance framework gave the partnership board confidence to approve AI use across the firm. The compliance team now has a clear, enforceable AI policy that meets SRA requirements, and every AI-assisted piece of work is logged and auditable. Client confidentiality is protected through the data classification system and the vendor selection criteria that ensure no client data is used to train external AI models.
The fractional CAIO arrangement proved highly cost-effective. Hartley Legal Group received senior AI leadership for a fraction of a full-time salary, with the flexibility to scale the engagement up or down as needed. After three months, the firm extended the arrangement on an ongoing monthly basis to provide continued governance oversight and strategic guidance as AI capabilities evolve.
In hard numbers, the fee earners using the tool each get back 15 to 20 hours a week, worth around £110,000 a year in recovered capacity at the firm's blended charge-out rate. Against fractional CAIO fees of £2,000 a month, the engagement paid for itself within the first month of full deployment, which is why the partnership board extended it to an ongoing arrangement.
As a fractional CAIO, ajairu gave us the governance framework and strategic oversight we needed without a full-time hire. Document review is 40% faster, and our compliance team finally has a clear AI policy they can enforce.
This engagement combined two of our core services:
The engagement succeeded because governance came first. Rather than deploying AI tools and worrying about compliance later, the governance framework was built and approved before any AI was used on client work. This gave the partnership board the confidence to support the initiative and gave the compliance team a policy they could actively enforce rather than retroactively patch together.
The fractional CAIO model was the right fit for a firm of Hartley Legal Group's size. They needed senior AI leadership to drive the initiative, but not full-time. The monthly arrangement provided exactly the right level of oversight: enough to ensure governance was maintained and new use cases were evaluated properly, without the cost of a permanent executive hire.
The human review checkpoint was critical to adoption. By designing the system so that AI accelerates the first pass but qualified lawyers always review and approve the output, the firm maintained professional standards while still capturing the time savings. This approach also made the AI tool easier to introduce to a team that was initially cautious about its role in legal work.
