Pearltrees Raises $6.7M For Its “Collaborative Interest Graph”

Pearltrees Raises $6.7M For Its “Collaborative Interest Graph”
Pearltrees, a company offering a novel interface for sharing and finding content, has raised 5 million euros ($6.7 million US) in new funding. The basic unit of the Pearltrees service is the pearl, which is basically a bookmark. Users can assemble these pearls into trees based around a topic. Meanwhile, Pearltrees is using that data to determine how different topics and bookmarks are related, and allows users to find new pearls (related to whatever topic they’re exploring) through its “related interests” button. Following the lead from Google’s PageRank and Facebook’s EdgeRank, Pearltrees has named its technology TreeRank. In essence, it’s offering its own version of the “interest graph”, a goal that many startups are chasing. Pearltrees launched in December 2009, and the company says it has been growing consistently at 15 percent per month, and that users have now created 15 million pearls which were assembled into 2 million trees. Previous investor Groupe Accueil led the new round.

Blog Archive » The Web’s third frontier Everyone realizes that the web is entering a new phase in its development. One indication of this transition is the proliferation of attempts to explain the changes that are occurring. Functional explanations emphasize the real time web, collaborative systems and location-based services. Technical explanations argue that the interconnectivity of data is the most significant current development. They consider the web’s new frontiers to be closely related to the semantic web or the “web of things”. Although these explanations are both pertinent and intriguing, none of them offers an analytical matrix for assessing the developments that are now underway. Pearltrees Comes To The iPhone, Goes Beyond Bookmarking And Adds Photos, Notes, Offline Mode Few startups make it through a year without a pivot or two these days. That really can’t be said about social bookmarking service Pearltrees, however. The company has stuck pretty closely to its roadmap ever since its launch in 2009. After launching on the web, Peartrees is now available on the iPad and, starting today, on the iPhone.

Content Curation for Teachers  Have you ever felt that there is simply too much interesting, educational content on the web? Fortunately, there are also some great, free products that help learners curate all of the many things they can read, watch, hear etc. on the web. The beauty of taking control of your content by saving and organizing links is that you can quickly find, revisit or share content with others. By curating the web, one can essentially build up a library of data in the cloud for free. I know personally as a history teacher, I spend a lot of time surfing the web when I prepare lessons. What the heck is an interest graph? Pearltrees raises $6.6M to show us Social curation startup Pearltrees has just sealed a deal for €5 million (around $6.6 million), all in the name of creating a better interest graph. Much is being made in current social media circles of the “interest graph” concept, which is more about what you know than who you know, and which purportedly has strong connections to purchase intent and other matters of concern to online marketers. Put differently, while social networks like Facebook focus on what you have in common with your friends and how you react to friends’ recommendations, interest graph-based models (like the ones behind Pinterest, GetGlue or Foodspotting) make social connections based on shared interests, not the other way around. “Pearltrees has leveraged social curation to create an open and collaborative interest graph of the Web,” said Pearltrees CEO Patrice Lamothe in a release. “As a consequence, Pearltrees harnesses the power of people to organize and discover the most valuable content on the web”, he said.

Start-Ups Aim to Help Users Put a Price on Their Personal Data Daniel Rosenbaum for The New York Times Shane Green, standing, founded Personal, a company that helps people control their personal data on the Internet, using what is known as a data locker. The data that people store in their locker can be as prosaic as birth dates, or as specific as a preference for spicy foods. People have been willing to give away their data while the companies make money. But there is some momentum for the idea that personal data could function as a kind of online currency, to be cashed in directly or exchanged for other items of value.

Pearltrees for teachers Year 2012 last post is a guest post from Finnish teacher Tommi Viljakainen. He is a teacher in Elimäki lower and upper secondary school. He teaches English, French and P.E. He is also interested in social media, iPad and the future of education.

Content Curation with PearlTrees Note: This post is also cross-posted over at the EasyBib blog. I’ve written and spoken before about the essential skill (a literacy according to Howard Rheingold) of students not only being able to collect content from their network(s), but to curate what’s collected. Just like a museum curator pours over artifacts to find the very best to display, we should also do the same not just for our own professional resources, but see it as an obligation to model it for our students. I came across a new resource recently (I believe the hat tip goes to Alec Couros for this find) called Pearltrees. After you sign up for your account, you can start building your own Pearltrees. Pearltrees are made up of “pearls”, or sites you want to curate into particular the Pearltrees (topics) you’ve created.

When is the social curation bubble going to burst? You just can’t move for social curation services right now. The biggest noise might be coming from Pinterest, which is growing like a weed — but whether it’s the new-look Delicious, Switzerland’s Paperli, shopping curation site Svpply, image service Mlkshk or another site, the fact is that almost everybody seems to want to help you save and sort and share the things you find on the web right now. With this swirl of activity, then, it’s no surprise to hear that Parisian service Pearltrees — slogan “collect, organize, discover” — has just raised another $6 million of funding, led by local conglomerate Groupe Accueil. The company, which has been running in public since 2009, welcomed the injection of funds as a way to help expand and scale up its system for bookmarking and organizing, which is based around a clustered visual interface. And it needs that scale. Right now Pearltrees is small and has moderate momentum, building up 350,000 users in the past three years.
