Aptible (YC S14) Handles The Hard Parts Of HIPAA Compliance

“The best minds of my generation are thinking about how to make people click ads,” entrepreneur and technologist Jeff Hammerbacher once said, paraphrasing Beat poet Allen Ginsberg in a sadly truthful characterization of the modern day tech industry.

The thing is, a lot of people who work in advertising-fueled tech products have said that they’re intrigued by the possibility of working on more meaningful applications of technology, particularly in the health space. But the complicated regulatory environment surrounding such products serves as a big deterrent. “Generally, health is just so heavily regulated, it’s just a painful business to be in. It’s not necessarily how I want to spend my time,” Google co-founder Sergey Brin said in an interview earlier this year. “I think the regulatory burden in the U.S. is so high, I think it would dissuade a lot of entrepreneurs.”

A new startup called Aptible just might help make healthcare a bit more palatable for ambitious entrepreneurs. Aptible, which is in the current classes of both the Rock Health and Y Combinator startup accelerators, says it helps handle all of the things a technology company needs to become HIPAA compliant at a fraction of the cost and effort of traditional HIPAA compliance consultancies.

Sliced Investing (YC S14) Launches To Bring Hedge Fund Access To The Common Investor

Sliced Investing today launched a tool to connect accredited investors who previously couldn’t meet the required minimum investment, to hedge funds.

You won’t be able to use Sliced to drop $1,000 into a hedge fund, but its service should allow qualified investors to deploy low five-figure sums into hedge funds that previously had mid-range six-figure minimums.

Sliced intends to get around minimums by pooling users’ capital into larger tranches. Users will be able to select a fund on Sliced that focuses on a certain strategy — say, equities or real estate — that meets their own investment bent. Other users can do the same, and after what the company calls a “threshold” is met, the accumulated monies will be disbursed into several hedge funds that match the selected strategy.

ListRunner (YC S14) Eliminates Hospital Paperwork

A majority of a doctor’s time is spent jotting down notes about a patient for the next doctor on duty over and over again with a pen and paper, according to Dr. Jeeshan Chowdury. His new Y Combinator-backed startup, ListRunner, promises to eliminate this paperwork with a mobile app...

ListRunner creates a digital record within the app that can be taken on-the-go and shared on a private network with other doctors. It works on both iOS or Android and it stays on, even if your phone hits a dead zone or isn’t near Wi-Fi. The most important part here, though, is that the app is HIPAA-compliant.

Kash (YC S14) Lets Retailers Offer Starbucks-Like Mobile Payments While Cutting Out Credit Cards

If you’ve been to a Starbucks in the past year or so, it’s almost guaranteed you’ve seen someone in line pay with their smartphone by opening the Starbucks app and holding a bar code up to a scanner. Kash is hoping to bring the same experience to other retailers and small businesses while cutting out one of their biggest costs: credit card fees.

Users just have to install the Kash app for iOS or Android. Unlike the Starbucks app, which forces you to create an account and enter your credit card information the first time you use it, Kash’s app just shows a green debit card labeled “tap to pay,” and the first purchase is on them. It’s a smart way of jumping straight to the best part of the app experience, even if the card does seem weirdly skeuomorphic in the otherwise flat iOS 7-style interface.

Kash gets around credit cards entirely, letting users pay straight from their checking accounts by entering their online banking log-in info, as you would with an app like Mint. Some people might not be comfortable with that, but Kash promises that it fully covers any fraud that could result from using its app. Since payments are being handled directly, retailers get paid for their sales in a day instead of potentially waiting days or weeks for things to go through traditional processors.

Think Gaming (YC S14) Demystifies Paid App Installs With A Mobile Gaming Co-Op

When we last checked in with New York-based Think Gaming, the company was hoping to create a sort of AngelList for mobile games in an effort to connect developers with strategic partners and investors. The company has refocused its business a bit since then, and is now seeking to help mobile game developers to get wider distribution by helping them to maximize their reach through install ads.

The company, which is part of the current Y Combinator class, has created what it’s calling a mobile advertising co-op. Through that co-op, gaming companies share data about the cost of the ads they’re purchasing across multiple networks, and the effectiveness of those ad networks.

App installs are a $10 billion global market, but until now most developers were in the dark about which networks perform best for their games, and the only way to find out was through trial and error. That gave major game developers like King and Supercell an advantage over indie gamers, simply because they already have the size, distribution, and marketing budgets to optimize their ad spend.

Demo Day Online

Our summer batch is big this year – approximately 85 startups will be presenting their products and services at our Demo Day next month.  We know that not everyone we’ve invited to Demo Day will be able to attend for the entire day (or at all), so we plan to put videos of the presentations online shortly after Demo Day so that invitees can watch any presentations they miss.  The videos will only be available to Demo Day invitees and password-protected, but ideally someday we can make Demo Day presentations available to a wider audience.

Tiempo (YC S14) Wants To Simplify Time Tracking So You Can Focus On Work

Y Combinator-backed Tiempo is a free time-tracking app for iOSAndroid and the web that can be used by individuals or companies to track employee hours to pay them faster.

Employees can log in hours and send it to their manager for approval. An approved invoice can be paid in moments, and the payment arrives in the employee’s bank account in less than 3 days.

Tad Milbourn, CEO and co-founder of Tiempo, said he, Peter Terrill and Kyle Kilat, who all met at Intuit, wanted to help people focus on work, rather than worrying about getting paid.
