Why Longevity Tech Is Failing Women Over 40
We are coding the future of health around male defaults. Women over 40 are being left behind.

In 2014, Apple launched its long-awaited Health app. It tracked everything; steps, sodium, blood alcohol. But not periods. Half the population. Gone from the dashboard.
It wasn’t a technical oversight. It was cultural. No one in the room thought menstruation was essential health data. It took a public outcry and a full year to fix. And even then, they tucked it under the wellness tab. Not vitals. Not system-critical. Optional.
Now, a decade later, we are doing it again.
We are building longevity dashboards. AI health coaches. Wearables that promise to optimize your aging process. But the defaults are still male. The baselines are still male. And menopause? Still missing.
No red flag when your sleep fractures, your joints ache, your heart risk triples. No dashboard that says: “Your biology is shifting. Here’s what to do about it.”
This is not a side case.
If we don’t design for the realities of women’s midlife, we’ll keep building tools that track decline without ever understanding its cause.
The question isn’t whether women will age. It’s whether we’ll notice.

The New Frontier in Aging Tech
In venture circles, they call it the silver tsunami; a wave of aging populations, and a trillion-dollar opportunity to build for older adults. The pitch decks are everywhere:
Apps for medication tracking
Robots for elder care
Platforms for end-of-life planning
But look closely and a pattern emerges: Most AgeTech is built for one end user: an aging man. It’s subtle. You see it in the data sets, diagnostic assumptions, UX defaults.
And it’s a problem.
Because women live longer. Age differently. And hit midlife with a physiological reset that rewires everything from bone density to brain clarity.
If your AgeTech doesn’t account for that, you are not solving aging. You are optimizing decline, just not the one women experience.
The Missing Dashboard
I wear a smartwatch that tracks my REM cycles. But when I started waking up drenched in sweat, mind foggy, heart racing, there was no alert. No pattern detected. No prompt to investigate estrogen or neuroinflammation.
Just silence. As if nothing important was happening. But something was. My biology was recalibrating itself and no one had built a dashboard for that. We are designing tech that notices every step, every heartbeat, but not the pivotal shift that reorients half the population’s health trajectory.
The Historical Lens: Male Biology as Default
This isn’t new. From seatbelts to statins, most health systems were built around male norms even when the female response diverged completely.
Now, longevity tech is repeating the same bias. But with a twist: it doesn’t just ignore women’s symptoms. It misses the market.

A Market Hidden in Plain Sight
Most investors picture aging as a gradual slope, an inevitable slow decline. But that’s not how it shows up for women. Between 40 and 55, something sharper happens. Hormones shift abruptly. And with that shift comes a cascade of health consequences:
Sleep disturbances
Cardiovascular changes
Rising inflammation
A spike in health-seeking behavior
This stretch of midlife isn’t a niche corner of aging. It’s where the curve bends. Where risk rises. And where attention is urgently needed. Yet capital continues to overlook it.
From Assistive Tech to Adaptive Systems
What if the next wave of AgeTech wasn’t about helping people die with dignity, but about helping women live with vitality? What if we stopped managing decline to designing for resilience?
We’d see:
Smart diagnostics for hormonal shifts
Sleep tech calibrated for midlife disruption
Cognitive tools for brain fog and memory gaps
Financial tools that factor in caregiving, divorce, and invisible labor
Musculoskeletal support for osteoporosis and strength loss
Nutrition and mental health platforms tuned to midlife biology
This isn’t science fiction. The science exists. The need is urgent. What’s missing is capital that knows what to look for.
Aging Needs a Gender Lens
If you are building in AgeTech and not talking to women over 40, you are not early. You are early to the wrong thing.
The female longevity curve is real.
It’s under-researched.
It’s underfunded.
And it’s wide open for those who know how to listen.
This isn’t about pinkifying health tech. It’s about building for biological reality and seizing the opportunity to reshape aging, not just extend it.

Fantastic article. I love the way you think! I am 53 and post menopausal and I can’t believe how bumbling in the dark this whole experience has been.
Including the gynecologist who prescribed the exact wrong thing for my needs. So frustrating.
I recently started a short video series called “Aging with Attitude.” I’m having a lot of fun with it - sharing things I have figured out that help me with all the menopausal issues.
Thank you for figuring out what a need this is & doing something proactive about it!!
I look forward to reading more from you !!!
I'm 68. Newly divorced, disabled and I have taken time to build a stable care team. I'm impatient at times but know how important it is for us to be heard
