BillForward (YC S14) Wants To Change The Way You’re Charged For Subscriptions

Amazon Prime, Netflix, utilities, the New York Times, HBO Go, the gym…

When you stop and think about all the subscriptions you have, the list probably is a bit longer than you thought.

But even as more subscription services become available, from ride shares to make up kits, it seems companies still offer customers limited subscription options due to constraints with their billing systems. Subscriptions rarely take into account how much you actually use them (If they did, most of us would probably be paying a lot more for Netlfix and a lot less for the gym).

Calling themselves “Stripe for subscription billing,” BillForward helps companies create customized billing services. BillForward CEO and co-founder Mark Parry said current subscription billing service software is outdated or difficult to use, and its time consuming and costly for companies to build their own.

San Francisco Open Exchange (YC S14) Aims To Be The E-Trade Of Bitcoin

Y Combinator-backed startup San Francisco Open Exchange (SFOX) is an online trading platform that helps people find the best bitcoin prices at various exchanges. In other words, it would like to help you buy, sell and invest in bitcoin exchanges kinda like and investor buys and sells stock on E-Trade.

Co-founder Akbar Thobhani left his job at Airbnb to create this platform. However, he soon found that using bitcoin was even more expensive than using credit cards. This is because there’s not a lot of transparency. So he started thinking that if he could find a way to compare prices this would help drive widespread adoption for the bitcoin market.

UPower (YC S14) Is Building Nuclear Batteries

Despite the promise of bountiful, cheap, and clean energy nuclear energy didn’t overtake fossil fuels like everyone expected them to in the middle of the 20th century. Among other things, fear of radiation leaks and waste products that have to be buried for hundreds of years turned the United States away from adopting it for more than a fraction of our energy usage.

Y Combinator batch company UPower Technologies is hoping to change that by offering reactors that cut out those factors at a scale where regulatory issues and billion-dollar construction costs aren’t a problem.

UPower founder and CEO Jacob DeWitte describes the company’s first reactor design as a plug-and-play nuclear thermal battery. The idea is that customers will order a reactor that will be shipped in a container with everything needed on the reaction side and then connected to a power conversion method that makes the most sense for the particular application. Some projects might hook it up to a steam turbine, while others might use it in concert with something much closer to a jet engine.

Women.com (YC S14) Is A Place Where Women Can Engage In Real Talk Online

From middle school girls’ sleepovers to more codified groups like the “Ladies’ Four O’Clock Club,” women have known for ages that there’s something special about the conversational dynamic that happens when a group of females get together. Above all, when women are in the company of other women that they trust, they often can be completely honest and comfortable in a way that they may not be in more mixed company.

A website called Women.com aims to be the go-to place where women can speak honestly with each other online, deliberately away from the male gender — a sort of Ladies Four O’Clock Club for the online world. The bootstrapped startup, which is co-founded by CEO Susan Johnson and CTO Neal Kemp, is launching this week out of the current class of Y Combinator.

Doblet (YC S14) Plans To Be Everywhere Your Phone Charger Isn’t

We’ve all been there. You’ve been out all day and suddenly that low battery alert pops up on your phone.

If you’re lucky, the bar you’re at might have the right charger for your phone behind the counter. If you’re not, you’re walking or taking the bus instead of calling a car service.

But with Y Combinator-backed Doblet, you might be able to get a charge even when you don’t have an outlet. The startup is putting portable batteries that charge Android and iPhone 5 phones in bars, restaurants and coffee shops. Users have the option of paying either $3 for a single charge or $30 for an annual subscription to the service and unlimited charges.

Vatler (YC S14) Wants To Be Your On-Demand Valet

If you drive to work in San Francisco, you probably know how difficult it can be to find an affordable place to park. Unless your office has its own parking, you’re likely paying to leave your car in a garage that’s not terribly close to where you work. And if you happen to work in SOMA, good luck paying less than $35 or $40 during Giants game days.

Vatler hopes to offer an alternative to having to deal with all that. It provides a way for you to order a valet through a mobile app, enabling you to drop your car off in front of your office and then request it whenever you’re ready to leave.

Hauteday (YC S14), a Gamified Shopping Site, Launches Out of Y Combinator

Out in California, a new site called HauteDay is hoping to gamify shopping to garner enthusiastic followers from a wholly different audience, women above the age of 30 — the kind who shop at Nordstrom and look up to Kate Middleton as a style icon. After a quiet beta phase, the startup will launch Tuesday at the tech accelerator Y Combinator's demo day.

uBiome (YC S14) Raises $4.5M From Angel Investors, Andreessen Horowitz To Crowdsource Microbiome Research

Microbiome is the ecosystem of bacteria that lives within us, which outnumber the number of human cells 10-to-1. Microbes in the microbiome perform functions such as digesting food and synthesizing vitamins and have also been linked to human mood and behavior.

Y Combinator-backed biotech startup uBiome wants to generate data and research from results of learning about the microbes in our bodies. The company, which raised $351,193 of its $100,000 Indiegogo campaign last year, offers three different swab site kits, with which people collect a sample, insert it in a tube and ship it back.

uBiome raised $1.5 million from angel investors and $3 million from Andreessen Horowitz.
