My story
The answer was already in my records.
For years every doctor handed me to another specialist. I saw 8 specialists and spent thousands on tests: 38 blood labs, 4 MRIs and 2 X-rays. The answer was in a blood test I'd taken years before. No one had compared it with my other results.

Why no one could see it
I had all the data. No one had the time.
None of my doctors were careless. Each one read their own slice of me in the few minutes they had, then passed me on. No one checked the intersection: how an old result, a new one and everything in between fit together.
15.7 min
The median primary-care visit. It covers about six topics, so most get around a minute.

What I tried
The apps and AI tools gave me pieces. Not the answer.
I tried the health apps, the trackers and the AI chats. Some gave me decent insights. Most repeated what my specialists had already told me. None of them read everything I had at once: my labs over the years, my scans, my sleep, my medications and my genes.
What worked
Then I read it all together.
I put every result in one place and cross-checked all of it at once. A blood test from years earlier, filed away as unremarkable, lined up with my newer labs, my sleep and my genes. On its own it said little. Read with everything else, it explained everything.
- That old blood test, on its own
- “Unremarkable.”
- Read with everything else
- The piece that explained it.
What happened
I took it to my doctor. This time, we found it.
I walked in with one pattern and the data behind it, instead of eight separate stories. A targeted test confirmed it, we treated the cause, and for the first time in years I feel like myself again.
That became Further Health.
So no one else has to spend years and thousands of dollars looking for an answer that's already in their records.
- Reads your wearables, labs, records and DNA together.
- Shows you what's worth raising, and the questions to ask.
- Keeps your data on your iPhone, encrypted. It isn't a medical device and doesn't replace your clinician.
“I built Further Health so the next person doesn't wait years for someone to read their records together.”
The team.
