Startup CISO Appointments: Bellini Capital/ConnectSecure, Datavault AI and Kai

Three announcements, three definitions

Press releases about CISO hires are written for customers, investors and the market. They are not job descriptions. Still, the wording a company picks shows what it wants the role to do. This guide reads three announcements: Bellini Capital and ConnectSecure on December 2, 2025, Kai on March 19, 2026, and Datavault AI on July 16, 2026. Each company is small, newly funded or publicly listed, and each describes the security seat differently.

Bellini Capital and ConnectSecure: a portfolio role tied to workforce

The December 2, 2025 announcement says Bellini Capital hired Brian Blakley to help cultivate a world-class cybersecurity workforce in Tampa and beyond. The release describes the investor as a Tampa Bay–based investment firm and innovation engine.

The CISO title covers more than one organization. The announcement says that, as part of his role within Bellini Capital's portfolio, Blakley will also serve as CISO of ConnectSecure.

The listed duties are about the product and the market, not only internal defense. The release says he will help develop ConnectSecure's Managed Cybersecurity Service Model for managed service providers. It also says he will align technology, talent and go-to-market strategy.

The background cited is compliance, enterprise risk and managed services. The release says Blakley brings more than 20 years of experience and has led transformations in those areas.

In this announcement the CISO is part industry advocate, part product strategist and part workforce builder, and the role is shared between an investor and a portfolio company.

Datavault AI: a listed company's technical mandate

Datavault AI's July 16, 2026 release gives the role a narrower and more technical shape. The company describes itself as Nasdaq-listed under the ticker DVLT. The release says Dr. Barry Childe will lead cybersecurity strategy and strengthen data protection across the platforms behind tokenization, valuation and secure data monetization.

The mandate is tied to the company's own products. The release says it centers on protecting critical data, advancing secure infrastructure and driving work in AI security and quantum-resistant technologies. Childe is quoted as saying he will support the safe deployment of the company's digital asset and tokenization platforms at institutional scale.

The credentials stress engineering depth over program management. The release says Childe has more than 40 years of experience across cybersecurity, high-performance computing, cloud infrastructure and distributed-ledger technology. It adds that he served as a Distinguished Engineer at HSBC, where he led the bank's blockchain and innovation initiatives.

CEO Nathaniel T. Bradley frames the hire as foundation work. He says bringing Childe onto the leadership team strengthens the foundation beneath everything the company builds. The announcement places the CISO on the leadership team and describes the job as security built into the product.

Kai: the CISO as internal proof of the product

Kai's March 19, 2026 release is the clearest case of a CISO whose job is linked to what the company sells. The company describes itself as the maker of an agentic AI cybersecurity platform. The release says Alfredo Hickman will oversee the security of Kai's systems and data while strengthening customer trust as the company scales.

It also gives him a second job. The release says he will operate Kai's agentic AI platform within the company's own environment. The text says this is meant to help shape, stress-test and mature the platform. The CISO is therefore both the person responsible for security and an internal user of the product.

The release points to experience at an earlier-stage company. It says Hickman was CISO at Obsidian Security, where he helped build the security organization from day zero. The funding context is given in the same release, which cites Kai's emergence from stealth with $125 million in funding and rapid adoption across Fortune 500 organizations.

The CEO's quote makes the product link explicit. Galina Antova says his leadership will be instrumental in ensuring Kai transforms security for customers and exemplifies that transformation internally.

What the three announcements share

Read side by side, the releases show several patterns in how these companies define the seat.

• The role is tied to the business model. ConnectSecure's CISO works on a managed service offering. Datavault AI's works on platforms for tokenization and data monetization. Kai's runs the company's own product internally.
• The audience is outside the company. Each release is written for customers, partners or investors, and each links the CISO to growth. Kai's mentions customer trust as the company scales. ConnectSecure's mentions helping service providers and small businesses.
• Credentials match the company's niche. Managed services and compliance appear for ConnectSecure. Cryptography and distributed ledgers appear for Datavault AI. Building a security program from day zero and managed security services appear for Kai.
• The CEO speaks for the hire. In all three releases a chief executive or the company's leadership supplies the framing quote, and each treats the appointment as strategic, not administrative.

What the announcements do not say

The documents leave out details a reader might want. None of the three states a reporting line, a budget or a team size. None describes board-level reporting or regulatory duties. The Datavault AI release lists risk factors in its forward-looking statements, including the company's ability to integrate new leadership and execute on its cybersecurity and secure-infrastructure plans. That is the only place in these documents where success in the role is described as uncertain.

The ConnectSecure release also shows a structural point: a CISO title can sit across an investor and a portfolio company, and the announcement does not explain how the two responsibilities are split. These are press releases, so they show how companies choose to present the role, not how it works day to day.
