Former Palantir executive to lead global operations and finance as Tines scales its mission to power the world's most important workflows

BOSTON and DUBLIN, July 28, 2025 /PRNewswire/ -- Tines, the intelligent workflow platform for security and IT teams, today announced the appointment of Heather Planishek as its Chief Operating and Financial Officer (COFO).

Prior to joining Tines, Planishek served as Chief Accounting Officer at Palantir Technologies, where she guided the company through a period of significant growth and its transition to the public markets. She has also held finance and operational roles at Hewlett Packard Enterprise and Ernst & Young.

In her new role, she will oversee global operations and finance, bringing deep expertise in operational strategy and financial discipline to help Tines scale globally and deliver long-term value for customers.

"Heather brings a rare combination of leadership, systems thinking and bias for action that aligns perfectly with how we're building Tines for the future," said Eoin Hinchy, CEO and co-founder of Tines. "Her experience scaling Palantir, a high-growth, AI-native company, gives her a unique lens on how to build durable operations within complex, fast-moving environments. That background will be invaluable as we continue to grow and serve some of the most advanced teams in the world."

Planishek joins Tines at a time of accelerating momentum following the company's $125 million Series C in February, which valued the company at $1.125 billion, and the launch of full-spectrum automation capabilities in June. With Tines, customers can safely integrate AI into daily operations, orchestrate workflows and agents across systems, teams, and tools, and operate with enterprise-grade scale and governance. The result is better ROI, stronger compliance, and faster outcomes.

"I'm thrilled to be joining Tines at such a pivotal and high-growth moment in its journey," said Planishek. "This is an incredible opportunity to help continue to scale Tines with both speed and purpose. When operational excellence is embedded early, teams across the company are empowered to focus on what really matters: delivering exceptional outcomes for customers."

Planishek is based in Colorado and will work closely with Tines teams across the U.S., Ireland, Europe, and Australia.
