> Then please provide some proof that proper DD was done.
If you are stating that "they [investors] failed to do due diligence", then the onus is on you to provide proof that the proper DD was done if you don't want your argument referred to as speculation. I am not drawing a conclusion one way or the other.
> The disruption came along one parameter only, the amount of blood required to do the test.
That wasn't the only disruption and I'm not sure that was the primary one: I would argue the primary disruption was regulatory (using/abusing the LDT framework and consumer-initiated testing).
> It is trivial to come up with a foolproof test to see whether or not Theranos has a working device.
I would never use the words trivial and foolproof for anything in medicine or laboratory testing: there is nothing simple about running a comparison between labs, especially for biological samples. Run an identical sample at Quest and Labcorp and the values will differ, perhaps in a statistically-significant way.
I agree in that I would expect that proper due diligence should have recommended against an investment in Theranos. Not participating in the scientific community is a giant red flag. I completely disagree that technical DD on the technology platform would necessarily reveal the flaws in Theranos.
So far not a single investor has claimed that their DD team did not have access, that their DD team was competent to do the job in the first place and that the technology as evaluated was sound. You'll note that this whole lawsuit is about claims by the company, not about what they actually had or what the DD team encountered in the lab.
> That wasn't the only disruption and I'm not sure that was the primary one: I would argue the primary disruption was regulatory (using/abusing the LDT framework and consumer-initiated testing).
The technology enabled that. Without the tech that failed to materialize and is not the core of the innovation that Theranos represents.

Yes, but if you run enough samples then you should converge at something amounting to statistical equivalence. If that doesn't happen then either one of the tests is invalid.
> I agree in that I would expect that proper due diligence should have recommended against an investment in Theranos.
ok. That's probably the most important point anyway.
> Not participating in the scientific community is a giant red flag.
As are secrecy, refusing access to labs, not providing full details on the technology under NDA, refusing to run a sufficient number of blind tests at the request of the DD team. Keep in mind that we're talking about a 100M investment, there isn't a whole lot that you won't be able to do when doing DD for a deal that size.
> I completely disagree that technical DD on the technology platform would necessarily reveal the flaws in Theranos.
If that were true that would mean they had working technology, which they did not have at all. Even for some of the most basic testing they had to fall back on equipment supplied by others and this would have definitely turned up in a real DD, barring magic I don't see how they could have gotten away with it in any realistic setting.
> So far not a single investor has claimed that their DD team did not have access, that their DD team was competent to do the job in the first place and that the technology as evaluated was sound.
This doesn't tell us one way or the other if DD took place and if so, the scope.
> The technology enabled that. Without the tech that failed to materialize and is not the core of the innovation that Theranos represents.
The technology is orthogonal to their regulatory machinations. They could have developed an in-house ELISA (or whatever, something more conventional) and made similar regulatory plays as they did with their microfluidics system.
> Yes, but if you run enough samples then you should converge at something amounting to statistical equivalence. If that doesn't happen then either one of the tests is invalid.
That handwaves over the complexity of the study, which goes to my point that your trivial and foolproof experiment is neither. A proper one probably needs a CRO. For a sizable investment it could be worthwhile, but I think you've underestimated the scope of your proposal.
> As are secrecy, refusing access to labs, not providing full details on the technology under NDA, refusing to run a sufficient number of blind tests at the request of the DD team.
Some of that in context isn't outside the behavior of other medical technology companies. It would be negligent to allow someone that wasn't with the government to walk through my lab without making some sort of arrangement ahead of time, and certainly under no circumstances unsupervised. I also have withheld key technical details to someone running DD despite having an NDA because NDAs cost money I didn't have to enforce if needed. The last item about testing is certainly a huge red flag, but [citation needed] if you're saying that Theranos did it (I find it possible to believe, but I haven't read that until your comment).
> If that were true that would mean they had working technology, which they did not have at all.
That might be an overstatement? I've followed this case closely, and I've had a very difficult time understanding what was claimed to work and did, what was claimed to work and didn't, what wasn't claimed by Theranos but is rumor transmuted into fact by the internet, etc. I've been operating under the assumption that the technology did work under controlled conditions and had problems when scaling up, but that is speculative on my part. I'm not aware of any scientific or medical reasons to believe that their platform cannot work, I am however aware of medical reasons to expect challenges to overcome (off-hand, sample volume, collection site), have violent disagreement as to the importance of consumer-intiated testing, etc. Unlike uBeam, there doesn't seem to be fundamental reasons to believe that Theranos' platform could not work and microfluidics being known to the art is supportive. If there are fundamental reasons that the technology cannot work, or if you have good hard sources for what Theranos had working and when, please do share!
> Even for some of the most basic testing they had to fall back on equipment supplied by others and this would have definitely turned up in a real DD, barring magic I don't see how they could have gotten away with it in any realistic setting.
"That's a great observation. It's true we do use conventional equipment for some basic tests and we are up front about that with our strategic partners, and it's simply because it's cheaper to run basic tests on the conventional equipment than on the Edison 1.0. Rather than waste money by insisting all testing run on Edison 1.0, we actually take the savings from running the basic tests on the conventional equipment, and roll that into the development budget for Edison 2.0 which we project will handle 98% of our full panel. Being intimately familiar with conventional equipment has other benefits: it's an important element of our development process to help us to better understand how we can deliver value-based differentiators on Edison 2.0." (or something like that) If they're willing to lie, they can spin a nice yarn and back it up with phony data. It won't fool everyone, but they don't need to fool everyone.
"Ok, let's run these samples I have here through your Edison 1.0 machine and see what the results are.".
At that point they could stall, pretend the machine isn't currently working (ok, I'll be back later), that processing samples and preparation takes a really long time (ok, I'll wait) (which would be dissonant with the turn around time for the results claimed in their publications, see 'breakthrough in instant diagnosis') and so on.
At some point the rubber will have to meet the road and they'll have to stick a sample into their machine and give up the results and that really is all you need.
As for unsupervised access to the labs, that wasn't what I intended to say with 'access', just access, to verify that what they claim their processes are are indeed the processes as practiced.
> Unlike uBeam, there doesn't seem to be fundamental reasons to believe that Theranos' platform could not work and microfluidics being known to the art is supportive.
Agreed, maybe it could work, but there is no proof that it ever did work, and the company has admitted the results were invalid:
And that's a huge difference. For uBeam the physics just isn't there, for Theranos there was a lot of skepticism about sample variability when you are using that little fluid drawn in that particular way.
But if any or all the components in that chain don't work then the chain won't work and the impression Theranos has made to the world is that it all worked.
> If there are fundamental reasons that the technology cannot work, or if you have good hard sources for what Theranos had working and when, please do share!
Yes, of course I have that, but you're going to just have to believe me, after all, why hold me to a higher standard than Theranos ;)? This is too secret to share, even with fellow participants on message boards and I'm not even asking for your money.
Kidding aside, what Theranos had working (if anything was working at all, my assumption based on their own admission is that it did not work at all beyond the simplest proof of concept) and when they had this on a timeline with their messaging to both investors, customers, employees and board members besides Holmes is a document that their investors would kill for right now. Some of that information is public or known to specific parties but it would take an insider leak or something to that effect to fill in the blanks.
Theranos has done a lot of damage to other companies trying to improve the world of medical diagnostics, that's an aspect that is far worse than any funds lost by investors.
