MyMilk Labs launches Mylee, a small sensor that analyzes breast milk at home

Many expectant mothers are told that breastfeeding will come naturally, but it is often a fraught and confusing experience, especially during the first few weeks after birth. Parents often worry about if their babies are getting enough nutrition or if they are producing enough milk. MyMilk Labs wants to give nursing mothers more information with Mylee, a sensor that scans a few drops of breast milk to get information about its composition and connects to a mobile app. The Israel-based company presented today at Disrupt Battlefield as one of two wild card competitors picked from Startup Alley.

The Mylee launched at Disrupt with a pre-order price of $249 (its regular retail price is $349). Based in Israel, MyMilk Labs was founded in 2014 by Ravid Schecter and Sharon Haramati, who met while working on PhDs in neuroimmunology and neurobiology, respectively, at the Weizmann Institute of Science.

Mylee deviceDuring the company’s stage presentation, Schecter said the device is meant to give mothers and lactation consultants objective information about breast milk.

Breast milk changes in the first days and weeks after birth, progressing from colostrum to mature milk. Mylee scans the electrochemical properties of milk and then correlates that to data points based on MyMilk Labs’ research to calculate where the sample is on the continuum, then tells mothers if their milk is “delayed” or “advanced,” relative to the time that has passed since they gave birth.

The device’s first version is currently in a beta pilot with lactation consultants who have used them to scan milk samples from 500 mothers.

MyMilk Labs already has consumer breast milk testing kits that enable mothers to provide a small sample at home that is then sent to MyMilk Labs’ laboratories for analysis. One is a nutritional panel that gives information about the milk’s levels of vitamins B6, B12 and A, calories and fat percentage, along with dietary recommendations for the mother. Another panel focuses on what is causing breast pain, a frequent complaint for nursing mothers. It tests for bacterial or fungal infections and gives antibiotic suggestions depending on what strains are detected.

Though some doctors believe testing kits are unnecessary for the majority of nursing mothers, there is demand for more knowledge about breastfeeding, as demonstrated by the line-up of breast milk testing kits from MyMilk Labs and competitors like Lactation Labs, Everly Well and Happy Vitals. Haramati said on stage that MyMilk Labs plans to eventually transfer some of the tests’ capabilities to the Mylee.

OmniVis could save lives by detecting cholera-infected water in minutes rather than days

Clean drinking water is one of the most urgent needs in developing countries and disaster-stricken areas, but safety tests can take days — during which tainted water can infect thousands. OmniVis aims to make detection of cholera and other pathogens as quick, simple, and cheap as a pregnancy test. Its smartphone-powered detection platform could save thousands of lives.

OmniVis, which presented on stage at Disrupt SF’s Startup Battlefield today, emerged from research conducted at Purdue University, where CEO and co-founder Katherine Clayton completed her doctorate. She and her advisors were working on the question of using microfluidics, basically very close inspection of the behavior of fluids, to detect cholera bacteria in water.

In case you forgot your Infectious Diseases 101, cholera is a bacterium that thrives in water polluted by fecal matter. When ingested it multiplies and causes severe diarrhea and dehydration — which as you might imagine can become a life-threatening problem if a community is short on clean water.

While normally uncommon, there was a huge cholera outbreak in Haiti in 2010 following a major earthquake there; 665,000 people were infected and more than 8,000 people died. It was this humanitarian disaster that prompted Clayton to look into how such an event might have been prevented. She’s been working on what would become the OmniVis platform since 2013.

“It’s been a long time coming,” she told me.

That’s not uncommon for academic spin-offs with valuable IP but zero product experience. Moving from lab bench to field-ready hardware has taken years of hard work. But the resulting device could upend a costly and slow water testing process that leaves communities at risk in crucial moments.

Existing water testing is generally done at a central location, a lab run by a university, utility, or the local government. It depends on the region — and of course if there has been a disaster, it may not even be functional. Going from sample collection to results may take several days, and it isn’t cheap, either. Clayton estimated it at $100 per sample.

“But that’s just supplies and labor,” she said. “Not the cost of the lab, the PCR machines — which are tens of thousands of dollars — the pipettes, the dyes, the disposables and consumables, the training… not to mention in a lot of areas you’re not just going to walk by a nice central laboratory. Some countries may only have one or two testing facilities.”

Another option is disposable rapid diagnostic tests, more like pregnancy tests than anything, meant for use with stool samples — but their accuracy is low even then, and with cholera diluted in a water source you may as well be flipping a coin.

Such was the state of testing when Haiti had its outbreak and Clayton began looking into it. In 2013 they began investigating microfluidics as a method for detection. It works by exposing a set of chemical reagents, or “primers,” to a water sample. These primers are engineered to bind to bits of cholera’s DNA and then when heated, replicate it — a process called DNA amplification.

The more cholera is present, the more DNA will be available to amplify, and it multiplies to the point where it affects the viscosity of the water — a factor that can be tested by the device. Interestingly, the device in no way “analyzes” the DNA or identifies it; all it does is measure how viscous the water is, which is a highly reliable proxy for how much cholera was present in it to begin with.

It turns out this method is both quick and accurate: In 30 minutes it gives as good or better results as central testing.

“The worst thing we could ever do is say there’s no cholera in the water when there is,” Clayton said. So they’re focused on robust test results over all else. But ultimately the device still had to go from the lab to the real world. To that end the team conducted pilot tests in Haiti, where they worked with local NGOs and communities to get some direct feedback.

What they found was promising — but also resulted in major changes to the product. For one thing, they had to switch from iPhone to Android.

“People feel safer with Android than iPhone, which is considered a luxury item,” Clayton said. They also found that men and women operated the system equally well — the team is 84 percent women, she noted, and their design choices may have crept into the product the same as can happen on what is much more common, a male-dominated team. English and Svengali users likewise did fine. Interestingly, locals were baffled by roman numerals. “That was surprising,” she said, but illustrative of how even the smallest assumptions need to be questioned.

“I love user-centered design,” Clayton said. “I think it’s the only way to get engineering to work. UX and graphic design is not my or my colleagues’ specialty, so we had to get some outside contractors for that.”

The production device, which OmniVis hopes to ship in about six months, should cost around a thousand dollars — but at about $10 per test it will pay for itself quickly, especially considering how much easily it can be deployed and used. A half-hour turnaround on a test that can be performed by an aid worker with an hour’s training is an invaluable tool in a disaster-stricken area where infrastructure like mail and roads may be in disorder.

These devices, by the way, are not bought and paid for by the people who drink the water. Like the water-testing labs, they’ll be owned and operated by NGOs, governments and others with budgets for this kind of thing.

Cholera is the first pathogen the company is aiming to detect, but the system can just as easily detect several others simply by using different disposable tests equipped with different primers. E. Coli could be next — with the proper testing, Clayton said. And others would follow. It’s not hard to imagine an OmniVis device being a must-have for any relief work where water needs to be tested.

Chris Dixon from a16z announces free crypto startup school at TechCrunch Disrupt

Chris Dixon, a general partner at Andreessen Horowitz, announced a new crypto-related startup school at TechCrunch Disrupt today in San Francisco.

Dixon says that the firm is not looking for equity, but really wants to provide a way to teach some best practices in the emerging field of crypto currency. “We are going to run a startup school for crypto-specific startups and what we’ve learned over the last 7 years as best practices in this category,” Dixon told TechCrunch’s Josh Constine on stage today.

The company doesn’t intend to charge any money, nor will it take any equity in the companies that participate. In Dixon’s words, they are doing this to push the category forward and help crypto startups get going. He hopes that based on the good will of offering this education for free, that startups who participate may end up having a conversation with a16z about possibly getting an investment, but he made clear that this absolutely was not a requirement.

Last year, the firm made its commitment to crypto clear when it established a crypto fund run by Dixon and Katie Haun. Dixon told TechCrunch at the time of that announcement that his firm had already invested in 20 crypto companies over the previous five years, including Ripple and Coinbase way back in 2013, prior to establishing a fund devoted to crypto.

The company has set up a page on the company website for companies interested in signing up for the crypto startup school.

Will Smith just dropped $10K on a startup that pitched him on stage at Disrupt

Actor and Hollywood media mogul Will Smith surprised the TechCrunch Disrupt SF 2019 audience this afternoon by announcing he would invest $10K in a startup that pitched to him onstage as part of an “elevator pitch” contest, where the winner would get to take a selfie with the star. The company,, helps companies with their social media presence. However, what got Smith’s attention was their well-delivered pitch, he said.

The startups didn’t get much time to prepare, having been plucked from the Startup Alley earlier in the day.

In addition to responding well to the pitch itself, Smith also liked the concept and the business model.

“As I built out my social media team, that was the idea — I wanted to take back my storytelling,” said Smith. “I think that’s hugely important.”

“That was really the best pitch so we’re gonna rock a selfie,” Smith said, jumping up to snap a photo with the founder.

Smith’s investment strategy isn’t usually this off-the-cuff, however.

Speaking onstage at the Disrupt conference, he also offered more details on his plans for Dreamers VC, the investment firm founded with Japanese soccer star Keisuke Honda, which was announced last year by Honda’s management firm KSK Group.

Smith noted the firm has an interest in “doing good” with its funds — pointing, in particular, to an investment in “Boring tech.” (He actually means The Boring Company, per the Dreamers VC website, where it’s listed alongside a host of others.)

He also offered a little background on how Dreamers VC came to be in the first place.

“Well, you know, I met with [Keisuke Honda] and we just hit it off immediately. And, you know, we felt like there was a beautiful intersection between being able to create businesses, but also to stay focused on solving problems of the world,” Smith explained. Honda already had banking relationships in Japan that were looking to make their way into the U.S.

“So the relationship worked out well,” he said.

Plus, Smith adds, “I had already been investing and he had already been investing and our values were in alignment. We want to solve some of the world’s problems. We want to do well by doing good.”

Render announces object storage service at TechCrunch Disrupt

It was a big day for startup Render, which participated in the TechCrunch Disrupt Startup Battlefield today. It also announced some upgrades to its managed cloud platform.

First of all, it announced the ability to spin up object storage in the cloud, while greatly simplifying the tasks associated with adding storage. CEO and founder Anurag Goel says that the storage option is something customers have been requesting, and as with their other services, they handle a lot of the heavy lifting for them.

“One of the things that our users want us to do next is to build out object storage. Even though they can use things like Amazon S3 and other cloud storage options, they know that Render is going to be easier for them to use. So they really want object storage, and they want everything in one place,” Goel explained.

If you want to do that today without Render, you would have to spin up a virtual machine in the cloud, attach the storage, set up backup schedules and take care of all of these other associated tasks, and what Render is doing with Render Disk is stripping that all away and managing the process for them.

While the startup was at it, it also developed a concept called infrastructure as code. This allows developers to define their infrastructure requirements in a YAML file. When the developer sends the file to GitHub, Render can build the infrastructure for the customer on the fly based on the contents of this file.

Finally, they are offering a one-click launch to customers. This could come in handy for companies that are offering free trials or open-source tools to enable users to launch their applications with a single click from GitHub and it will load all of the required files.

Brex wants to replace startup bank accounts with Brex Cash

Brex, a Silicon Valley fintech darling, has lofty plans to battle big banks —and Stripe.

Code-named “Gemini,” Brex today announced a new product designed to replace and improve the functionality of traditional bank accounts. Brex Cash, as it will be known publicly, is a business cash management account integrated with the Brex Card, a corporate card for startups launched in 2018.

Brex tells us they’ve built the core banking infrastructure from scratch, allowing the company to forgo third-party processing fees and provide a much-needed tech infusion to antiquated banking systems. In partnership with Boston’s Radius Bank, Brex Cash will allow customers to send payments quickly and easily with no transaction fees attached. Rather, Brex plans to reward its users for making or receiving payments using Brex Cash with points redeemable for cash back, travel and air miles. Customers will also receive 1.6% yield on deposits.

It’s not a bank, but in practice, it can replace a bank, says Brex co-founder and co-chief executive officer Henrique Dubugras .

“Our idea is that new businesses —the new Y Combinator companies we hope a big percent of them never open a bank account,” Dubugras tells TechCrunch.

Brex now has many similarities to a bank. What differentiates it is its lack of physical branches — it’s exclusively digital — and it’s insurance. Traditional banks are insured by the Federal Deposit Insurance Corporation (FDIC), which protects up to $250,000 per depositor. Brex Cash users are protected by the Securities Investor Protection Corporation (SIPC), a nonprofit agency overseen by the U.S. Securities and Exchange Commission that protects up to $500,000 and specializes in protecting customers of brokerage firms from the loss of cash and securities.

We think we’ve won a lot of credibility. Before, who was going to give their money to a random-ass startup called Brex? -Brex co-CEO Henrique Dubugras

Additionally, Brex invests its customers’ money in a money market mutual fund of U.S. treasury bonds. “If Brex goes out of business, customers’ money will be safe,” the company writes in a press statement. “The only scenario where money could be lost is if the U.S. government defaults.” [Update 10/2/2019: Brex says this quote alone is taken out of context, rather, the company was trying to communicate that it would take something like the U.S. government defaulting in order for Brex customers’ money to become unsafe.]

“It’s not that we are inventing this — this model exists with Fidelity,” says Dubugras. “Fidelity isn’t necessarily a bank — we are bringing that concept to businesses to give lower fees, better interest rates, better experiences and more security.”

Brex, a graduate of the winter 2017 Y Combinator cohort, has quickly become a Silicon Valley success story for the ages. The rapid adoption of its startup credit card, which doesn’t require a personal guarantee, and its ability to issue cards instantly and provide higher limits than other options on the market has attracted thousands of customers and venture capitalists. The business, led by a pair of young Brazilian repeat entrepreneurs, including Dubugras and co-CEO Pedro Franceschi, has collected more than $300 million in equity funding, including a $100 million C-2 financing that valued the company at $2.6 billion earlier this year.

“There will always be customers that are skeptical, but I think by starting out with a card, we built a lot of trust,” Dubugras said. “It was us giving them money instead of them giving us money. A few years in … We think we’ve won a lot of credibility. Before, who was going to give their money to a random-ass startup called Brex?”

In the weeks ahead of TechCrunch Disrupt San Francisco, where Dubugras announced Brex Cash on Wednesday, the CEO told TechCrunch that Brex had no immediate fundraising plans and that they were “waiting for the right time” to raise again. As for what’s next, he said the company is discussing the launch of a debit card and plans to add another 100 employees in the next year, bringing the Brex headcount to 400.

The Brex news follows the launch of Stripe Capital, a new offering from payments behemoth Stripe that will make instant loan offers to customers on its platform, and the announcement of the Stripe Corporate Card. Akin to Brex, Stripe will issue a no-fee, no interest rate credit card intended for Stripe customers. Brex and Stripe, two Y Combinator grads, will go head-to-head in a battle for customers, particularly YC grads looking for friendly financial tools.

Immediately following Stripe’s announcements, the business announced a $250 million funding at a $35 billion valuation. Brex may be following a similar playbook, announcing a major product on the heels of a large capital infusion.

Brex Cash represents a new era for the company. Though the product may be costly for Brex, it opens the business up to thousands more potential customers. Now, any startup, regardless of funding, can create a Brex account to store cash, explains Dubugras, and all companies using Brex Cash will be immediately issued a Brex corporate credit card.

“If you’re starting out, if you don’t have funding yet, you can still receive your payments using Brex,” Dubugras said. “That’s a super big deal for us.”

Brex Cash was built under product lead Ritik Malhotra, who joined the team as part of an acquisition of his startup, Elph. Brex poached the company, which was focused on blockchain infrastructure, right out of YC for an undisclosed amount. In retrospect, the deal looks much more like an acqui-hire of Malhotra, who had the digital payments infrastructure acumen necessary to complete this project.

“It’s an easy way to move money, which is the lifeblood of a business,” Malhotra tells TechCrunch of the new product.

Brex Cash is itself not a cash cow for Brex; rather, the startup makes money on purchases made on its corporate card, in which it charges the merchant, not the customer. This model is particularly beneficial when its customers are spending a lot of money, growing quickly and raising capital. In a downturn, however, this model isn’t as attractive.

Brex seems unconcerned with the possibility of an impending recession. Brex writes that even in downturns, entrepreneurs will start companies and attempt to raise money. The Brex Cash product, regardless of the economy, will help Brex better underwrite Brex Cards, as it gives them better access to a customer’s financial health.

In a battle against Stripe, Brex is at a disadvantage. At only two years old, the company may have garnered a lot of credibility in a short time but it doesn’t have the decade of experience building fintech products that Stripe has and, more importantly, it doesn’t have 10 years of customer loyalty.
