Underdog’s responsible play innovation fund, GuardDog, has announced a new investment in Regen, a financial wellness platform designed to help players save money automatically while participating in sports betting, fantasy sports, and prediction markets.
Regen allows users to link their gaming accounts and set aside a small percentage of each entry, regardless of whether the outcome is a win or a loss.
The savings process runs in the background and does not require players to change how or how often they play, positioning the product as a passive financial management tool rather than a traditional limit-setting mechanism.
As part of the investment, Underdog will feature Regen within its responsible play hub, promote the platform through customer support and responsible play communications, and provide access to the tool for its employees. Financial terms of the investment were not disclosed.
Adam Warrington, VP of Responsible Gaming at Underdog, said: “With major shifts happening in our industry, it is important to further our dedication to building a stronger and more responsible ecosystem.”
Warrington added: “Regen’s mission aligns with our goals as they empower users to set up a simple and intuitive savings mechanism that provides a new and evolved responsible gaming tool.”
GuardDog was launched by Underdog in 2023 as a dedicated fund to support startups developing responsible play and player protection technology.
In addition to capital, the fund offers portfolio companies access to Underdog’s product teams and industry expertise, with a focus on tools that can operate across fantasy sports, prediction markets, and other regulated gaming formats.
The investment comes as US operators continue to reassess how responsible play tools are deployed, particularly as gaming activity expands beyond traditional sportsbook models into adjacent formats.
In December 2025, Underdog confirmed it would cease sports betting operations in North Carolina, citing a business decision, while continuing to offer fantasy sports products in the state.
The exit marked another step in the company’s shift away from operating a US sportsbook and toward fantasy and prediction-based offerings.
Underdog Fantasy partnered with Sportradar in September to integrate the Bettor Sense AI-powered responsible gaming solution, becoming the first US-based operator to deploy the technology
