Approov Appoints Silicon Valley Veteran Rex S. Jackson as Chairman of the Board

Key Terms

mobile app attestation technical

A mobile app attestation is a technical check that proves a mobile app and the device running it are genuine and haven’t been tampered with. It uses cryptographic signals from the device or operating system to certify the app’s identity and integrity, like a tamper-evident seal on a package. For investors this matters because attestation helps reduce fraud, protect user data, and support regulatory compliance, which can affect a product’s reliability and market trust.

api security technical

API security is the practice of protecting the digital doorways that allow software systems to communicate, share data and perform actions on behalf of users. It uses controls like access checks and encryption to prevent unauthorized access, data leaks or malicious use—think of it as locking and monitoring doors in a building that also transmit sensitive documents. For investors, weak API security can lead to outages, regulatory fines, customer loss and reputational damage that materially harms revenue and stock value.

cryptographic mobile app attestation technical

A cryptographic mobile app attestation is a technical proof that a specific mobile app and the device it runs on are genuine and have not been tampered with, created using digital keys and signed statements from the device or platform. For investors, it matters because it helps ensure that transactions, account access, or data coming from a mobile app are authentic—like a sealed, signed letter that confirms both the sender and the integrity of the message—reducing fraud and operational risk.

non-executive director regulatory

A non-executive director is a member of a company’s board who does not work for the company day-to-day but provides independent oversight, strategic guidance and checks on management. For investors, they matter because they act like an impartial referee or outside advisor, helping ensure decisions protect shareholder interests, reduce risks of poor governance, and add credibility to financial reporting and long-term strategy.

Dr. Lucio Lanza, longtime chairman and early backer of the company, continues on the Board

EDINBURGH, Scotland & PALO ALTO, Calif.--(BUSINESS WIRE)-- Approov, a leader in mobile app attestation and API security, today announced the appointment of Rex S. Jackson as independent Chairman of its Board of Directors. Mr. Jackson succeeds Dr. Lucio Lanza, who has been recognized for his years of leadership and who will continue to serve on the Board as a non-executive director.

Rex S. Jackson, Chairman, Approov

Mr. Jackson brings more than three decades of executive and board leadership in Silicon Valley technology companies. He has served as Chief Financial Officer and General Counsel across multiple public and private technology companies, most recently as CFO helping lead ChargePoint through its merger and public listing. He currently serves on the board of Terra Innovatum (Nasdaq: NKLR), where he chairs the audit committee and serves on the compensation committees. Mr. Jackson holds a J.D. from Stanford Law School and a B.A. from Duke University.

“Rex is a rare combination of financial, legal and operational leadership, and he knows Approov deeply,” said Ted Miracco, Chief Executive Officer of Approov. “As autonomous AI agents, mobile apps and APIs become the front line of enterprise security, the opportunity ahead of us is enormous. Rex’s experience guiding technology companies through their most consequential phases of growth makes him the ideal independent chairman to help take Approov to the next level.”

The company also paid tribute to Dr. Lanza’s tenure. A legendary figure in semiconductor and electronic design automation investing, Dr. Lanza backed Approov’s vision early and has chaired its Board through years of sustained growth, championing the company’s pioneering work in cloud-based cryptographic mobile app attestation.

“Lucio’s conviction, vision and dedication have shaped Approov from the beginning,” Mr. Miracco continued. “His belief in our technology and our team never wavered, and his fingerprints are on every milestone this company has achieved. We are delighted that the Board will continue to benefit from his counsel.”

“It has been a privilege to chair this Board and to watch Approov define a category,” said Dr. Lucio Lanza. “The question of whether software talking to your APIs is genuine — an authentic app, un-tampered, on a safe device — has never mattered more than it does in the age of AI agents. Rex is precisely the leader to guide Approov’s next chapter, and I look forward to supporting him and Ted from my seat on the Board.”

“Approov solves a problem the entire industry is waking up to: proving what is on the other end of an API call,” said Rex S. Jackson. “I have watched this team build remarkable technology and a business, and I am honored to serve as chairman. I look forward to working with the company to capture the opportunity ahead.”

The appointment was approved unanimously by Approov’s Board and shareholders, including investors Maven Capital Partners, Lanza Tech Ventures and Scottish Enterprise.
