Koefoed previously served as CFO of OneStream Software, guiding it through a July 2024 IPO.
Harness recently closed a $240M Series E round at a $5.5 billion valuation.

Koefoed's background includes leadership roles at Microsoft, Skype, and Puppet Inc.
The appointment focuses on scaling finance operations for global market opportunities.
Bill Koefoed brings extensive experience in financial planning, investor relations, and corporate development to Harness. Most recently, at OneStream Software, he was instrumental in growing the company's Annual Recurring Revenue (ARR) from $50M to over $700M. His tenure culminated in a successful IPO and a subsequent $6.4B acquisition by Hg. His deep familiarity with public markets and high-growth environments is expected to be a major asset as Harness matures its AI software delivery platform.
"Bill is exactly the kind of executive we need as Harness scales to meet the market opportunity in front of us," said Jyoti Bansal, founder and CEO of Harness. "He has done this before — building world-class finance organizations, navigating complex growth stages, and helping companies reach defining financial milestones. His experience across public markets, investor relations, and high-growth technology businesses makes him the ideal partner."
The transition to AI-driven software development has created a massive market opportunity for platforms that can ensure speed, compliance, and security. Koefoed highlighted that Harness is uniquely positioned to help enterprise teams keep pace with this fundamental shift. By leveraging the Harness AI and Software Delivery Knowledge Graph, the platform automates repetitive manual work, allowing organizations like United Airlines and Morningstar to deploy software up to 70% faster.
"AI is fundamentally changing how software is built, and the companies that win will be those that can deliver it just as fast," said Koefoed. "That's exactly what Harness enables — the speed, compliance, and security that enterprise teams need to keep pace. Harness has the product, the customers, and the momentum that every growth-stage company works toward."
