About Aziz & Kaye Business Law

Aziz & Kaye Business Law is a boutique firm with a business-oriented approach across Corporate Law, Transactional Law, and Economic Competition. The firm is known for practical, creative advice and long-term client relationships, serving as a strategic bridge for foreign clients entering or expanding in Mexico. Innovation sits at the center of how the firm operates, from adopting advanced legal technology to embedding AI into daily legal workflows to deliver sharper outcomes for clients.

Opportunity

At Aziz & Kaye, adopting generative AI wasn’t a “nice-to-have.” It was a decision anchored in client trust. “The most critical challenge was ensuring the confidentiality of client information,” says Partner Rebeca Sanchez. As a law firm, confidentiality and data protection are non-negotiable, so any platform had to be secure enough for live client matters.

That bar matters even more in the firm’s Competition practice, where the pace and complexity of matters keep rising. Investigations and merger reviews can involve thousands of documents — emails, PDFs, spreadsheets, platform exports, and chats — often under compressed timelines. And the enforcement environment is changing fast. As Senior Associate Carlos García Cueva puts it, regulatory authorities increasingly use technology and IT forensics to leave “no stone unturned.” For a mid-sized firm, that creates a clear mandate: “catch up, level up, or surpass.”

Aziz & Kaye recognized that increasing headcount would not resolve this challenge. They needed leverage — capacity and consistency — without scaling headcount.

Solution

Aziz & Kaye evaluated multiple AI tools before selecting Harvey. “Harvey stood out because not only did they meet all of our rigorous security and confidentiality requirements, but it was built specifically for legal professionals,” Sanchez explains.

Just as important for a mid-market firm, Harvey offered flexibility in deployment and adoption, and backed it up with a true partnership model. “We value the fact that we have an open channel of communication with Harvey’s team,” she adds. “If we identify a feature we need or suggest improvements, there is a constructive dialogue.”

Aziz & Kaye treated AI adoption as a practice capability, not a one-off tool rollout. The goal was to embed Harvey into daily legal workflows where it could reliably increase speed and rigor without compromising judgment.

Across Corporate and Competition matters, Harvey now shows up where the work is hardest — and where quality matters most.

• Corporate and M&A due diligence: In transactions, due diligence can become a bottleneck. Aziz & Kaye uses Vault as a first-level review accelerator, quickly analyzing large volumes of documentation to surface key issues, potential risks, and areas that warrant deeper attention. “This significantly accelerates the initial review process,” Sanchez notes, “and allows our team to focus its time on deeper legal analysis rather than purely mechanical document screening.”
• Drafting in Word: In complex agreements, technical errors can create real downstream risk. The Harvey for Word Add-In helps the team catch broken cross-references, improper defined terms, numbering inconsistencies, and structural issues — work that traditionally requires painstaking manual checks. By automating parts of this process, Harvey reduces human error and raises confidence in final deliverables.
• Competition matters at scale: In antitrust work, speed is only useful if the output remains defensible. Harvey supports AI-augmented legal research, large-scale review, and argument development under tight timelines. García Cueva describes the broader imperative clearly: if regulators are technology-enabled, law firms must be too. Harvey helps Aziz & Kaye stay “regulator-ready” — keeping work timely, data-grounded, and built to withstand scrutiny.
• A “sparring partner” for strategy and negotiation: Beyond productivity, Aziz & Kaye uses Harvey to sharpen legal thinking. “I often use Harvey not to build my argument for me, but to challenge it,” Sanchez explains. She asks it to identify weaknesses, counterarguments, or alternative interpretations — stress-testing positions before presenting them to a counterparty or regulator. “In that sense, Harvey functions as an intellectual sparring partner,” she says, “helping refine legal strategy.”

Impact

For Aziz & Kaye, Harvey delivers leverage where mid-market firms need it most: capacity, consistency, and defensibility. Lawyers reinvest saved time into higher-value analysis, client engagement, business development, and new service creation.

Next, the firm is doubling down on repeatability. The team is expanding workflows for merger screening, RFI management, compliance diagnostics, and document review pipelines — so Aziz & Kaye can do more with less, keep quality uncompromising, and stay ahead as enforcement and client expectations become increasingly tech-enabled.
