I think you might be over-interpreting this. Perry's LinkedIn profile still states that she was CEO until September 2018. What's in a LinkedIn CV, anyway? People can doctor them as they like, or make just plain stupid errors...

I can absolutely 100% with complete certainty tell you that I am not over-interpreting this.

If you say so... Either you have additional insider information that you are not disclosing, or I sense a logical fallacy here.
Is there anything about uDream that's actually honest. Asking for a friend.
The Art of Manufacturing was around the end of June '18, I think she still was CEO then, or perhaps she just thought she was.

I think it might have been recorded at the end of April but not made available until June.
Someone posted a link to a short presentation by the current uBeam CEO at OurCrowd summit earlier this year. Some interesting data can be gleaned from the slides (assuming it's not just completely random data they threw up!)

No one wants to charge their phone @ 1W at a distance of 20cm, and at horrible efficiency.
No one wants to charge their phone @ 1W at a distance of 20cm, and at horrible efficiency....using a charger that makes your phone the size of a brick, needs to be held in the air and aligned, and costs hundreds of $$$.
And there you have it, as we all knew uBeam is a flop for charging your phone. THE thing that Perry said was doable from the start.
No one wants to charge their phone @ 1W at a distance of 20cm, and at horrible efficiency.
Or 0.35W at 2m, at even worse efficiency
I love how they used the elipse bubble to inflate the figures, just draw a straight line from each tip and that's your data, probably best case.
No wonder they had to pivot to low power IoT.
In 2013 getting your phone charging at 1W at 1m was respectable. Today... no.

iPhone X (and most phones today) use a 10Wh battery, which is good (in my experience) for 7AM->9PM so ... ~14-15 hours.
Average power consumption is therefore ~700mW.
800mW would charge your phone (reeeeeaaaaaalllllllly ssssssssssssssslllllllllllllllllllllllllllllllllooooooooooooooooooooowwwwwwwwwwwwww!).
But if you did have 24/7 wireless power, 1W is all you will need to keep your battery full.
Now, if you have line of sight, range, and orientation issues, you obviously need more. If you can only charge 50% of the time you need 1.5-2W. If you can only charge 10% of the time.... you need 7-10W.
From the demo they gave at the ourcrowd summit it was clear that
The large unit (the one on the top of their twitter account) has some tracking and phased array capabilities
The small unit (the one they advertise as beta kits), is a good old plane speaker, directing high volume ultrasound forward, no tracking or even detection of receivers.
("Excuse me, I'm a bit low, could you put your phone under a piece of paper so I can get some charge?")

Jacqueline McCauley in no longer with uBeam.
Still on the website though....., I guess the website guy also left.
No need for a CFO if you have no money left.

"Excuse me, I'm a bit low, could you put your phone under a piece of paper for the whole week so I can get some charge?,
Sure, no problem, I can't look at the screen anyway in this room as it keeps rotating near the uBeam transmitter, the accelerometer goes crazy here"
I think we should also look at the financial side of charging/powering devices. Some numbers about recharging your gadgets via the standard SMPSU based on the average price for power in Germany (EUR 0.30 per kWh) which is quite expensive. The yearly cost for recharging daily:
- smartphone EUR 1 - 1.50
- tablet EUR 4
- laptop EUR 10
Any wireless charging solution has to compete with those numbers. A few bucks more for the convenience of not dealing with a cable might be acceptable. But anything much less efficient or much more expensive is a show stopper.
BTW thanks for calling me CTO and not VP Eng, Berte is going to be so pissed about that!
