Pet longevity is moving from a niche idea to a defined field, and Together Everis positioning itself at the center of that shift. The venture is building a science‑driven platform focused on extending the healthy years of dogs and cats, advancing its first science-backed longevity formulation through validation and into commercial readiness. Together Ever is simultaneously building a research-grounded longevity platform and a first-generation formulation pipeline.
At its core, Together Ever is designed around a simple but emotionally powerful question: if aging is increasingly understood as a biological process that can be influenced, why shouldn’t that insight be applied first to the animals people consider family? The brand’s answer is to translate aging science into daily, practical rituals for pet owners, starting with a flagship longevity powder now progressing through scientific validation and translational preparation for market introduction. That candor is central to the brand’s positioning: the story is about a platform being built with the same long-term rigor that precedes category-defining nutritional products.
A New Category For “Time Together”

Together Ever defines itself not as a traditional pet supplement business but as a “pet longevity” venture, focusing on healthspan—the years of life spent active, functional, and relatively free of age‑related disease. The venture is built on the idea that aging pathways, such as mitochondrial function, metabolic regulation, and inflammatory balance, can be proactively supported in companion animals, long before serious illness appears. In practical terms, that means designing interventions intended to preserve vitality over time rather than treating problems only after they emerge.
Its flagship concept is a daily longevity powder for dogs and cats centered on a proprietary complex called Revionyx. This formulation is being developed to support cellular health and energy metabolism, drawing on conserved biological pathways that aging researchers have mapped across species. Revionyx is currently progressing through structured scientific validation, including controlled veterinary studies in companion dogs designed to characterize biological age markers, functional aging trajectories, and long-term safety, as part of its translational pathway to market introduction. The brand’s priority is executing a disciplined, science-first path to commercialization.
Together Ever is positioning itself as one of the first platforms to systematically define “pet longevity” as a distinct scientific and commercial category. Instead of positioning itself around single issues like joint support or coat health, it is presenting longevity as an integrated system: a combination of biology‑driven formulations, preventive thinking, and daily emotional rituals between humans and their animals. This framing distinguishes the venture from established pet wellness brands and underscores its ambition to shape how owners, veterinarians, and researchers discuss time spent with companion animals.
Where Science Meets Emotional Design
What Together Ever is building rests as much on feelings as on formulas. The venture begins from the observation that many modern pet owners form bonds with their animals that resemble parent‑child relationships, particularly in urban environments with fewer children and more single‑person households. That emotional reality, combined with the inevitability of loss, makes the idea of “more healthy years together” especially resonant. Together Ever’s work is an attempt to give that desire a science‑first structure, turning it into something actionable rather than purely sentimental.
Central to this approach is the concept of emotional design translated into standardized product systems, formulation protocols, and scalable daily-use rituals. Rather than thinking only in terms of ingredients and dosages, Together Ever studies how people actually care for their pets day to day; the language they use at the food bowl, the routines they maintain, the quiet negotiations over treats and mealtimes. Early prototypes focused less on complex packaging or aspirational branding and more on integrating longevity into existing rituals, such as a familiar scooping-and-mixing motion at dinner. The venture concluded that unless a longevity practice could fit seamlessly into that moment, it would be unlikely to become a lasting habit.
Co-Founder Suoyi Feng brings a background in aging research to this intersection of science and emotion, shaped by his training at the University of California, Berkeley, under the mentorship of Dr. Michael J. Conboy, a pioneer of heterochronic parabiosis and systemic regulation of aging. In that research setting, frontier questions of tissue rejuvenation, stem-cell aging, and cross-tissue signaling were actively explored, with studies suggesting that aging can be modulated at both cellular and organismal levels. That scientific lens later converged with a personal appreciation of the relationships people have with their pets. The result is Together Ever’s guiding premise: companion animals can serve as both emotional anchors and biological models, making them uniquely suited to be the first large‑scale gateway for longevity interventions.
The Pet‑To‑Human Longevity Loop
Beyond pet care, Together Ever holds a broader, long‑term ambition: to create what it calls a Pet‑to‑Human Longevity Translation Platform. In this vision, companion animals become a bridge between cutting‑edge aging science and eventual human applications. Because dogs and cats share human environments yet have shorter lifespans, they provide an observable, ethically acceptable model for studying how interventions affect aging and healthspan over time. Data from such work is intended to inform both veterinary practice and, in the long term, future human longevity strategies.
Together Ever’s early milestones reflect this translational mindset. Developing the Revionyx complex is one piece, but Together Ever is equally focused on advisory relationships with scientists, veterinarians, and longevity researchers, as well as on validating key longevity pathways in real‑world companion animals. By situating its work at the intersection of biology, behavior, and emotion, the brand is attempting to create a feedback loop: scientific insight shapes products and rituals, those rituals generate engagement and outcomes data, and that data, in turn, feeds back into both pet and human aging research.
Feng captures the subtlety of this approach in an unexpectedly candid observation about the industry. “What almost no one admits is that the biggest bottleneck in longevity isn’t just the science—it’s whether people will show up for the science every single day,” he says. “When we started Together Ever, we discovered that owners were more consistent about their dog’s nightly feeding ritual than about their own health routines. That was the quiet revelation for us: if you want to build a real longevity platform, you start where the emotional discipline already exists – at the food bowl, not the medicine cabinet.” It is a warm but pointed insight into how a pet‑first model might eventually reshape human choices.
Building A Scientific And Commercial Foundation For Scale
Together Ever is in active platform-building and scientific validation, focused on establishing long-term credibility as it advances to large-scale commercialization. The venture’s goals are explicitly stated: in the short term, it wants to establish itself as a thought‑leading brand in pet longevity, articulating how aging science, emotional design, and daily rituals can work together. In the medium term, it aims to deepen scientific credibility and trust through veterinary collaborations, advisory networks, and early adopter communities. The longer‑term aspiration is the complete Pet‑to‑Human Longevity Loop, in which validated pet interventions help normalize and inform human aging strategies.
This deliberate pacing is part scientific caution and part brand philosophy. By emphasizing scientific discipline over premature claims, Together Ever signals that it does not want to be mistaken for yet another over‑promising supplement label. Instead, it presents itself as a longevity platform being built with long-term scientific and commercial rigor, creating its ecosystem in parallel with product finalization and engaging veterinarians, researchers, and early partners as part of its category-formation strategy. That transparency may prove to be an asset in a space where “anti‑aging” rhetoric is often met with justified skepticism.
The venture’s narrative also reflects an understanding that the actual test of its vision will come not from lab metrics alone, but from ordinary lives. As Revionyx and future products move toward market introduction, their success will depend on whether pet owners feel a precise alignment between the science, the ritual, and the emotional stakes of their relationships. In that sense, Together Ever is designing not only for dogs’ and cats’ biology but also for human behavior: the small, repeated acts of care that quietly shape how long and how well animals live.
As the brand continues to evolve, Feng returns to the human element that underpins the entire effort. “Most people don’t dream about extra years in the abstract,” he says. “They dream about one more morning with their dog at the end of the bed, one more slow walk that doesn’t feel like goodbye. Together Ever exists because those moments matter enough to design around. Our work is to build the scientific and emotional foundation, so that when the products arrive, they are worthy of the trust people place in them—and worthy of the time they hope to share.”
