The 2018 ourCrowd investment in uBeam has disapeared from theOurcrowd website  https://www.ourcrowd.com/companies/ubeam
The site has been updated to say they only invested $4,830,407 “in one previous round” that happened in 2015, the 2018 round is not there anymore.

During the Ourcrowd summit, (3 months ago) ourcrowd said they invested (before the summit) $6.5 in uBeam (this was after Meredith "decided" to quit)

Looks like ourCrowd did raise $3m for an investment in uBeam in 2018
(see =https://www.sec.gov/Archives/edgar/data/1658187/000146581818000005/xslFormDX01/primary_doc.xml) .

My take on this is:

OurCrowd did raise $3m in 2018, but the money was 100% in some kind of escrow pending some milestone (uBeam did file investement docs to the SEC so they did receive the money).

a few months ago ourCrowd were planning to release ~50% of the escrow, probably hoping the new CEO would cure the company.

2 weeks ago, they decided not to release the escrow and take the money back, essentially killing the company (and the new CEO's CV)

Escrows being escrows, my guess is that ALL the investors in the second round pulled their investment.
A quick review of websites of the 2018 round shows....
Andreessen Horowitz (uBeam not found on website search)
Upfront Ventures (ubeam still on their website)
Founders Fund (nothing on search)
Ludlow Ventures (still there with a picture of Meredit).
Mark Cuban also participated, and appears he still keeps this line on his CV.

It's pretty limited, only works within 1 meter, fixed transmitter and receiver. I estimate about 1.5 to 3% efficient overall, with between 0.5 and 1 Watt to the battery. It's at the SAR safety limit, so no increasing from here, it's as powerful as it gets.

I've only just seen this. I'm particularly wondering how it practically co-exists with other 2.4GHz ISM services such as WiFi, Bluetooth and wireless peripherals like keyboards and mice. If they're managing to see 0.5 to 1W at the receiver, good luck with the LNA compression & sensitivity on any other in-band service on the Ossia powered device. It'll be like trying to listen to someone whispering at an AC/DC concert.

In addition, like other RF solutions, this might get by in the US by pushing the envelope on FCC regulations, but I highly doubt this will be able to achieve global acceptance without an uphill struggle with a plethora of other local regulators and regulations.

Their own press distances themselves from this approved system as a practical product, it's interesting marketing, and as always the tech press is dumb enough to fall for it and is talking about charging phones and 1000s of devices. I doubt this will ever be a product, the purpose is to get a Part 18 Approval (after having tried to avoid that for years).

Their wireless charging has the slight flaw in that is stops wireless devices working, and don't bother with 5.8GHz they're going there as well, someone should try using US sound waves instead. :horse:

Just saw the latest EEVblog video.  At 13minutes in, Dave is saying the LED pattern doesn't follow the movement.  Couldn't this be attributed to the phased array's tracking error?  That is, it's changing where the array is pointing as the turret sweeps the room to keep power at the target.
