Author of the Arazzo Specification joins Jentic to help define the orchestration layer of enterprise AI
DUBLIN, IRELAND (September 29, 2025) Jentic, the AI infrastructure company connecting agents to the world’s APIs, today announced that Frank Kilcommins, who is one of the most influential voices in API strategy and the principal author of the Arazzo Specification, has joined the company as Head of Enterprise Architecture. Kilcommins will lead Jentic’s standards-based architecture efforts and guide large-scale enterprise adoption of AI agents with safety, clarity, and control.
Arazzo Comes Home
Arazzo, the standard Kilcommins helped to author under the OpenAPI Initiative, has emerged as a foundational technology for building machine-readable workflows. It gives AI agents the ability to perform deterministic, multi-step operations across diverse APIs, without relying on unreliable natural language guides. As a further contribution, Jentic has also published “Arazzo Engine”, an open-source headless automation engine that allows Arazzo-based workflows to be created and executed by AI agents.
“Frank has led the foundational work to make agentic AI safe and dependable in enterprise settings,” said Sean Blanchfield, co-founder and CEO of Jentic. “His vision in creating Arazzo gives us all a crucial and timely open standard for representing agentic business logic, allowing agents to reliably orchestrate complex tasks, while driving performance, energy efficiency, security, audibility and compatibility. We are proud to have him leading our next phase of architecture.”
Kilcommins is the fourth contributor to recently join Jentic from the OpenAPI Initiative. He follows Erik Wilde, the OpenAPI ambassador, and two of the most prolific developers behind the Swagger OpenAPI tool suite used by enterprises globally.
From OpenAPI to Agent-Oriented Architecture
Frank Kilcommins’ career spans enterprise architecture, developer evangelism, and standards development. He spent over a decade leading API transformations inside large multinational companies before becoming Principal API Evangelist at SmartBear. As a member of the OpenAPI Initiative’s Business Governance Board, he played a key role in transitioning the organization from a single-spec body to a multi-spec standards group.
His significant contribution with Arazzo solves a longstanding gap in the API ecosystem: how to reliably describe and automate complex workflows that span multiple endpoints and systems. It provides a machine-readable contract that AI agents can follow without guesswork, making it possible to safely delegate multi-step tasks to software.
“AI agents need more than access to APIs. They need a structured, verifiable map for how to use them to achieve intended goals with precision and efficiency,” said Frank Kilcommins. “That is what Arazzo delivers. It helps increase agent completion rates for complex workflow actions. Its deterministic properties give companies confidence in exposing and managing APIs in the AI era. And Jentic is building around this vision from the ground up. I joined because this is where the future of reliable AI infrastructure is being written.”
The Technical Leadership Layer for Enterprise AI
Kilcommins’ arrival reinforces Jentic’s position as the company defining the orchestration layer of enterprise AI. He will lead architectural development and enterprise adoption of agent infrastructure based on Arazzo, OpenAPI, and other emerging standards.
This announcement builds on a wave of recent hires from the OpenAPI community and signals a larger movement. Jentic is not just building agents. It is building the standards, architecture, and trust layer for agents to operate at the heart of regulated, secure, API-driven businesses.
The appointment also coincides with the closed beta of Jentic’s Standard Agent, which is a hosted, open-standard service for deploying AI agents in production environments with integrated credential management, workflow validation, and real-time execution.
About Jentic
Founded in late 2024 and backed by $4.5M in pre-seed funding, Jentic is building AI agents for work. The platform operates at the API layer, not the browser, connecting agents to thousands of services using open standards, secure credential management, and Just-In-Time Tooling. Jentic is open source and based in Dublin, Ireland.
