K1x, an industry-leading AI-native private markets tax platform built for the full K-1 lifecycle, today announced three executive appointments across product, marketing, and finance. Christopher Sanders joins as Chief Financial Officer, Jessica McAlpine as Chief Product Officer, and Heather Teicher as Senior Vice President of Marketing. The appointments come as K1x expands its focus from automating complex tax workflows to helping customers use tax data to make more informed decisions and manage their tax operations more effectively.

Following its $175 million growth investment led by Sumeru Equity Partners earlier this year, K1x is strengthening its technology, product, and operational capabilities to support its next phase of growth. The expanded leadership team brings the expertise to advance the company’s AI-native platform.

“Automating complex tax processes has been an important part of what we’ve built, but there’s an opportunity to do much more with that information,” said John LaMancuso, CEO of K1x. “We’re bringing together the expertise to advance our technology, translate it into products that solve real customer challenges, and build the business infrastructure to support that work at scale.”

As Chief Financial Officer, Christopher Sanders brings a proven track record of scaling high-growth SaaS organizations and driving long-term enterprise value. Previously CFO at Ready Education, with earlier finance and operations leadership roles at Northpass and Syncsort, Sanders will partner closely with K1x’s CEO and Board of Directors to embed data-driven decision-making and operational rigor across the company, pairing scalable infrastructure with actionable analytics to optimize capital allocation.

Jessica McAlpine will lead K1x’s next phase of product development as Chief Product Officer, shaping the company’s product vision and roadmap and translating technical innovation into practical customer value. A former CPA and most recently Vice President of Product at OneStream, she brings firsthand understanding of the challenges tax professionals face. Her priorities include evolving K1x from helping customers prepare and compile returns to helping them steer their tax business, supported by a disciplined approach to product management and a structured, consistent release cadence.

Supporting K1x’s growth strategy, Heather Teicher, Senior Vice President of Marketing, will lead the company’s positioning, category leadership, and go-to-market efforts. She brings nearly two decades of experience and a “one revenue team” mentality, focused on strengthening cross-functional collaboration and aligning the go-to-market organization around shared business objectives.

Together, the appointments reflect the company’s focus on delivering greater value to customers while aligning its product, go-to-market, and operational strategies to support sustainable growth.
