FORT WORTH, Texas--(BUSINESS WIRE)--ProbablyMonsters, an independent video game company focused on building original IP through a focused, scalable development model, today announced the expansion of its executive leadership team. Jonathan Lander joins as Chief Publishing Officer, David Reid joins as Chief Marketing Officer, and Mark Subotnick now serves as Chief Product Officer, aligning product leadership with the company’s broader C-suite structure.

The appointments reinforce the company’s integrated development and publishing strategy as it continues scaling a diversified portfolio of original titles. Operating with centralized infrastructure that supports focused development teams, ProbablyMonsters structures its slate across near-, mid-, and long-term projects designed to deliver high-quality, intentionally scoped games built for long-term growth.

“As we continue building a balanced portfolio of original games, strong product and publishing leadership is essential,” said Harold Ryan, founder and CEO of ProbablyMonsters. “Our strategy is grounded in focus and discipline, with a long-term lens. Jonathan, David, and Mark bring the experience and judgment needed to help our teams execute at a high level and deliver great games to market with clarity. We are committed to building an environment where talented developers can do their best work, and that requires both meaningful support and a high-performance bar.”

ProbablyMonsters’ model is designed to give developers the resources, operational clarity, and long-term visibility needed to build original IP with focus. At the same time, the company maintains rigorous expectations around craft, collaboration, and accountability. As it grows, leadership is deliberate about building teams aligned to this standard and prepared to deliver consistently at a high level across game development and publishing from greenlight through launch.

Mark Subotnick now serves as Chief Product Officer, leading development operations and portfolio planning across the company. He previously served as Head of Studios, overseeing development teams across multiple projects.

Lander previously served as Senior Vice President of Global Product and Publishing Operations at Bethesda Softworks, supporting major releases from Bethesda Game Studios, ZeniMax Online Studios, id Software, and MachineGames. At ProbablyMonsters, he will guide release planning, franchise development, and long-term publishing strategy as the company continues expanding its internal publishing capabilities.

David Reid joins as Chief Marketing Officer, strengthening the company’s publishing-led go-to-market strategy and overseeing global brand positioning and player engagement across the portfolio.
