Thank you for the comprehen=ive feedback Steven.

For me the main value is that the system is an order=of magnitude cheaper than existing technologies, premised on leveraging dat= to help users see what daily elements are affecting their blood sugar, and=predicting dangerous highs and lows before they happen so they can take act=ons beforehand. To date, their beta app has lowered blood sugar averages in over 5=% of users 2x better than the world's most prescribed diabetes drug, Metfor=in. Which means that with the help of the date diabetes would need to use l=ss drugs. However I'd agree on complexity of regulations and saturation on the mar=et.

I run Day One Ventures fund and b=sed in San Francisco. I'd be happy to connect in person sometime to learn a=out about your experience and tell about our investments and opportunities l=see.

Greetings Masha,
<=iv>

I apologize for the delay. I was at some events in i= UK where I did not have connectivity.

I have work=d on a related portfolio company so I will have to be a bit abstract on the=specifics of this opportunity. So please excuse these brief thoughts.=Also, the only information I had was what was provided in your mail which w=s limited relative to any detailed analysis.

* In g=neral the challenge with glucose measurement is the finger prick. Any devic= that relies on this will only be marginally better than any other device, w=ether or not there is software or a slightly more convenient measuring devi=e. This is a statement about the inconvenience of a prick (and long term ch=llenges) but also the medical challenges on relying on that point in time.<=div>

* My sense is that going down the path of an innovation, that stil= has a prick, but requires a level of FDA approval is a difficult one to ap=roach.

* This is a very crowded space. There are a lot of apps, a=lot of measuring devices, a lot of mixtures of app and measuring devices. 1= is very difficult to avoid appearing as a commodity to consumers.

* While I understand there is potential to see innovation using novel appr=aches to analysis of data, it is not clear to me how much better the approa=h can be for an individual with data.

* The real opportunity I mi=ht see is around measuring glucose or some related telemetry to assist in c=mpliance that is outside the scope of a finger prick and measuring glucose d=rectly. It seems like we should have some other data point upon which to ap=ly machine learning.

I hope this helps...any frien= of JE is a friend of mine.

<=pan>Center Health is building a= Al-based glucose monitoring system for the 1 in 11 Americans who suff=r from diabetes, based on machine learning and their personalized Al, =ria.

Pros

— Existing glucometers from big companies=are very old-fashioned and outdated, those companies make their revenue fro= overpriced strips — Direct competitors, such as =/span>iHealth and Dario have negative customer reviews and minor —&=bsp;Uses FDA-approved circuits to get the approval in an automated manner</=ont>
