Rock Health is wrapping up the year in style by updating its Innovation Maturity Curve with the hottest trends of 2025 and sharing its predictions for what lies ahead.
The curve uses three major data points to plot innovation:
- Research volume – gauges the potential of a topic through PubMed publications.
- Venture funding – tracks investment as a leading indicator of commercial interest.
- Partnership activity – uses industry partnerships as a proxy for commercial traction.
The pace is picking up. Here’s a look at the categories that defined the year:
Longevity (Maturity Score: Developing) – Companies are pushing past one-off diagnostics to see whether personalized baselines can anchor ongoing care. Function Health just hauled in a massive $298M Series B for its “operating system for human health,” and other players like Hone Health have started expanding their models with in-home services.
- Keep an eye on: How much will insights on hormones or heart health translate into adjustments that patients actually act on? Rock Health expects this segment to hinge on turning long-arc patterns into timely guidance that’s both credible and valuable.
Mental Health Chatbots (Maturity Score: Emerging) – Some AI chatbots might be shutting down, but just as many are doubling down. Slingshot burst onto the scene with $93M to build “the world’s first foundation model for psychology,” and incumbents like Spring Health have even started launching bots to evaluate the safety of other bots.
- Keep an eye on: Regulatory scrutiny is intensifying as states begin banning AI-driven therapy. Some startups might be able to navigate the roadblocks, but Rock Health thinks others might pivot to lower-risk territory like keeping patients engaged between visits.
Health Benefits 2.0 (Maturity Score: Emerging) – OOP spending continues to climb, while employers just notched the steepest benefit cost increase in 15 years. Those pressures cracked a window for non-traditional models to gain traction, such as ICHRA frontrunners Thatch and Venteur.
- Keep an eye on: The benefits pressure cooker is heating up in 2026, which means this category isn’t going anywhere. As more costs shift to consumers, Rock Health anticipates the benefits experience to start looking even more like a set of adjacent marketplaces rather than a single plan.
The Takeaway
Digital health is moving faster than ever, and AI is only going to keep accelerating innovation. Rock Health’s full report is well worth checking out for more details on these categories and other up-and-coming segments like wearables (smart rings are especially hot), precision medicine (digital twins had a big year), and climate health (think allergies and air pollution).
