Berlin-based 6Wunderkinder is adding more features to its new Wunderlist Pro paid tier of service today, answering the number one request of its users with the addition of file upload and sharing. Users can add files to tasks and synchronize them across devices and team members for collaboration purposes. That, along with newly introduced pricing plans for Wunderlist Pro aimed at businesses, should help growth of the revenue-driving service skyrocket, says 6Wunderkinder founder and CEO Christian Reber.
“We had large corporations contacting us the first day we launched Wunderlist pro and ask us ‘Can we use this in our business, what can I do to sign up my entire team of 250 people?,’ etc.” he said in an interview. “That was exciting for us but unfortunately we didn’t have the business accounts yet, we didn’t have the dashboard to manage those people.” This change will help them sign on these new customers who have just been waiting for an opportunity to get on the platform.
The changes today aren’t only aimed at business customers big and small, however; Reber says that file sharing is something that should appeal across its user base, and drive up the value perception even for individual Wunderlist users who have been considering the paid option. “We think that files is a feature that everyone wants, and we think that we will see a very high conversion rate of free users to premium users also, because it’s a feature that everyone just asked us to build,” Reber explained.
Reber says they “quadrupled” their own internal expectations for new user growth with the introduction of Wunderlist Pro. The entire user base of nearly 5 million Wunderlist users (including free and paid) is around 29 percent U.S.-based, he said, but 40 percent of the paid customers come from the States. Over 40 percent of paying customers are businesses, too, which is why the business plan rollout is designed to unlock more of that potential market.
Ultimately, 6Wunderkind’s strategy is to become just as essential and widespread a productivity tool as a Dropbox or an Evernote, Reber tells me. Those have validated their business model, he says, though they target a completely different market. The aim is to grow from a simple to-do list to more full-featured collaboration software, while retaining focus on both individuals and business customers, instead of just one or the other.
Reber wasn’t ready to share specifics about conversion rates on Wunderlist Pro just yet, but he says that 6Wunderkinder does plan to be much more transparent about that kind of data with future releases, since it believes there’s value in showing other startups how it’s doing building a business, so expect to see more granular detail about how Wunderlist’s monetization strategy is working out in the near future.
On-demand car service Uber is looking to raise another big round of funding, this time led by private equity firm Texas Pacific Group we’re hearing. And so is Dan Primack. And Liz Gannes. The round is expected to be between $150 million and $200 million, at a valuation of about $3.5 billion. The round hasn’t closed yet, but it’s close to being completed, or so our sources say.
The funding comes as Uber is growing fast, expanding into new territories and adding lower cost services. AllThingsD reports that the company is expected to pull in $125 million in revenue this year, which is higher than had been expected.
Uber is now available in more than 35 cities around the world with its on-demand black car service. But it’s quickly adding lower-cost options in many of those markets. In several cities, that means lower-cost hybrid cars taking passengers, while in others, the company is partnering with local taxi companies to use its e-hail service. With the funding, it will likely expand even more quickly.
TPG isn’t your typical tech investor, although it has held stakes in companies like SurveyMonkey and Travelocity parent company Sabre Holdings. But it has done a fair amount of investing in travel and leisure companies, including a number of airlines and hospitality businesses.
On that front, Uber seems like a good fit, as it’s not your typical tech investment. The company is looking to disrupt the urban transportation industry, which has been stifled by decades of regulation. But it’s also built a logistical framework that could be used for any number of things: in the past it’s experimented with barbecue and ice cream delivery, and it’s even been used to order canal boats in Amsterdam and water taxis in Sydney.
Google Ventures is also expected to be an investor in the round, according to Gannes and Primack, though we hadn’t heard about that.
Uber has raised $57 million since being founded in 2009. Its most recent funding round was for $37 million in late 2011, and came from investors that included Menlo Ventures, Jeff Bezos, Goldman Sachs, Benchmark, CrunchFund*, and Troy Carter. Other investors include Benchmark Capital, First Round Capital, Lowercase Capital, Founder Collective, and a whole bunch of angels.
Uber, TPG, and Google Ventures all declined to comment for this story.
* DISCLOSURE: Some time ago, Michael Arrington founded TechCrunch. Later, he founded CrunchFund. And at some point after that, CrunchFund wrote a check to invest in Uber. But that all has nothing to do with why I’m writing this story about someone else possibly writing a check to invest in Uber.
Home 3D printers – particularly FDM, Makerbot-like devices – are still in their infancy and, as such, are untested when it comes to safety. That’s why some researchers at the Built Environment Research Group at the Illinois Institute of Technology decided to test a popular model for ultrafine particle emissions, a measure of how much junk these things emit while in use.
The result? PLA, a starch-based material, emitted 20 billion particles per minute while ABS, a plastic, emitted 200 billion. This is similar in scale to using a gas stove, lighting a cigarette, or burning a scented candle. In short, it’s a significant bit of potential pollution in an unfiltered environment but it’s nothing we don’t do to ourselves on a daily basis already.
The study didn’t take into account what materials were being expelled, which makes it a bit more troubling. For example, according to PhysOrg, ABS is known to be toxic in lab rats but PLA, oddly enough, is used in nanotechnology for the delivery of medicines.
What’s the takeaway? Ventilate your 3D printer.
Because most of these devices are currently sold as standalone devices without any exhaust ventilation or filtration accessories, results herein suggest caution should be used when operating in inadequately ventilated or unfiltered indoor environments. Additionally, these results suggest that more controlled experiments should be conducted to more fundamentally evaluate particle emissions from a wider arrange of desktop 3D printers.
Obviously these devices are designed for home and office use and probably will never end up under a lab-grade ventilation hood. However, given the various processes used to make 3D objects, it’s important that this research is done to reduce the effects of UFPs on children who may be using these in schools as well as the teachers, designers, and makers who use them on a daily basis.

While iOS games started out as either simple physics or casual simulation titles when the platform launched about five years ago, the bar has gotten steadily higher and more hard-core. Midcore studios like Kabam started to rise in prominence.
Now the iOS platform might be seeing is most hardcore title to date – a very, very massive multi-player title from YC- and Menlo Ventures-backed Machine Zone.
The company, which started out doing text-based RPGs a couple years ago like iMob, is launching Game of War: Fire Age. It’s a title where players build and grow empires, train massive armies, forge alliances with other players to win kingdoms.
The game can handle hundreds of thousands of players concurrently in the same universe, which is not an easy technical feat. Blizzard’s World of Warcraft, in contrast, typically handles a few thousand players simultaneously in a single realm. All movement on the game’s map is visible to everyone else.
“We wanted to take the company to the next level and be really ambitious,” said Machine Zone CEO Gabriel Leydon. “We decided to build some things that had never been done before. We had the capital to do it and the willpower.”
Leydon didn’t hire just typical game designers to build the title. He also found people who had experience in scaling massive systems. The game’s user interface is in HTML5 and is rendered natively, allowing the company to handle different screen sizes.
The other really cool thing about the game’s social capabilities is that there is a mechanical turk-like translation system where the players themselves translate chat in exchange for virtual currency rewards. That helps Game of War have really interactive play with a proper critical mass of users who can talk to each other, even if they don’t speak the same language. The in-game chat system helps Game of War get manage slang and gamer speak, which a third-party translation system probably wouldn’t handle correctly. If say, 50 players translate the same words in the same way, then the game will start using that translation automatically.
“It’s like a highly structured Facebook,” Leydon said. “My goal as a game designer was to create a feeling of what it would be to be a king, where you’d have a lot of people under you. You’d have to subjects, wealth and land.”
Assuming say, the game grows to 1 million players, there might only be 20 kings in the game. To reach that level, players have to woo others to form alliances with them. Within those alliances, there are ranks for different officers.
“This is a very hardcore game. This is not Candy Crush,” he said. “This is a complex system with a lot of potential trees of outcomes. If you’re the type of person that’s fascinated by systems like this, then this is for you.”
Machine Zone used to be known as Addmired, and rebranded last year when it took $8 million in funding from Menlo Ventures. Leydon said this is what the company took the round for, even though its older titles like Original Gangstaz and iMob 2 were pretty lucrative early on.
