Inkling’s interactive ebook publishing platform, Habitat, also now supports iPhone.

Inkling is based in San Francisco and backed by Sequoia Capital as well as major textbook publishers like McGraw-Hill and Pearson.

Inkling works with textbook publishers to rebuild existing textbooks for the iPad, incorporating search, quizzes, note-sharing, audio and video other interactive features. Students can preview free sample chapters and can also buy textbooks by the chapter, starting at $2.99, through Inkling’s store.

In March, Inkling raised funding from McGraw-Hill (NYSE: MHP) and Pearson, the world’s two largest textbook publishers. Inkling now has 33 textbooks in its library, up from 14 in March, and has agreements to develop the top 100 undergrad titles from McGraw-Hill Education, as well as other titles from McGraw-Hill, Pearson and Wolters Kluwer Health.

Inkling’s announcement comes a day after CampusBookRentals.com, which rents textbooks of the paper variety, announced that it raised over $20 million.

Over 11 million people are using Evernote’s service through either the Web or mobile devices, the company said in a press release announcing the new round of funding from Sequoia Capital. The idea is to let users save pictures, e-mails, text snippets from Web sites, or other things they come across on their daily trip across the Internet, and make them accessible from any device. The company’s logo is an elephant: as in, you’ll never forget.

Evernote said it’s trying “to build [a] global platform for human memory,” and hired Ken Gullicksen formerly of Morgenthaler Ventures (a partial participant in the funding round) to develop an acquisition strategy for the company as part of the new funding. It’s also trying to encourage software developers to build applications around its technology, and plans to hold a developer conference in August to try and drum up interest.

“I think that the cuckoos have flown out of their clocks,” Moritz tells The Times. “But eventually gravity will take hold and the cuckoos will fall to earth.

“I would tell investors right now to wear the Nancy Reagan button that said ‘Just Say No’. The two most powerful letters for investors are N-O. The difference between two letters and three letters right now can be really profound.

“A lot of people who are purchasers today were in high school in 1999. Those who decide to climb aboard everything will find themselves among the crash victims. And it’s going to be a long list of victims.”

Sugar had already made several acquisitions over the last year aimed in part at diversifying its revenue beyond display advertising. It picked up private sales site MyPerfectSale in October, as well as daily deals site FreshGuide in June.

The company’s latest funding round brings its total backing to $46 million. Sugar had most recently raised $16 million in a funding round in June 2009. It used some of the proceeds of that round to buy back the shares it had sold in 2007 to NBC Universal (NSDQ: CMCSA). The media conglomerate at one point handled Sugar’s ad sales, although it took back those operations nearly three years ago.

White-label app store Appia today announced that it has raised a $10 million round of investment from Venrock, the VC firm started by the Rockefeller family. Dev Khare, the VP of Venrock, will join Appia’s board as part of the deal.

The primary business for Appia is offering a white-label app store that partners with various mobile operators, portals and other brands looking to get into that business but not wanting to go through the whole process of setting up and building out the inventory for it alone. Currently there are some 130,000 apps in Appia’s catalogue.

Among recent deals, the mobile browser developer Opera recently launched a store with Appia — which resulted in the Opera app getting ejected from GetJar’s app store for violating a non-compete clause.

Getting taken off GetJar’s store might impact Opera’s traffic to some extent, but tut that kind of head doesn’t seem to be deterring investors. This most recent funding comes after a $15 million round raised last August from Eric Schmidt’s Tomorrow Ventures and the BlackBerry Partners Fund, when the company was still called PocketGear — it rebranded as Appia in Feburary. Total funding for the company now stands at $29.8 million.

Another play at app stores, but from the enterprise angle, has also seen some investment: Apperian, started by the ex-Apple (NSDQ: AAPL) employee Chuck Goldman, has picked up $9.5 million in funding led by North Bridge Venture Partners, Bessemer Venture Partners, Kleiner Perkins Caufield & Byers’ (KPCB) iFund, with participation also from CommonAngels and LaunchCapital, who provided the startup with seed funding.

Apperian’s main idea is to provide a platform to enterprises so that they can effectively create their own walled app stores for their employees — a big area not only for smartphone use but for the growing number of tablets that are getting adopted by businesses. Apperian currently provides this service for the iOS platform (iPhones and iPads) but will be extending it to Android soon.

Bubble Motion, which runs the voice-based social networking service Bubbly, has raised $10 million. The round was led by SingTel Innov8, the pan-Asian operator SingTel Group’s VC fund, with participation also from Singapore’s Infocomm Investments, Sequoia Capital, Palomar Ventures, and NGC.

Since launching one year ago, Bubbly has picked up 7 million users in India, Indonesia, Japan and the Philippines, which follows a similar structure to Twitter with followers and the like, except that instead of posting short texts people can post audio clips. The funding will be used to extend the service into further countries and to expand to more platforms such as smartphones, the mobile web and more service provider partnerships (like Twitter’s early days, it bases a lot of its current messaging around deals with individual mobile operator partnerships).

Sundrop Mobile has picked up $900,000, in a round led by Vocap Ventures, to extend its mobile loyalty solutions business: it offers merchants a system whereby they use a consumer’s mobile phone number instead of a loyalty card to collect shopping information and push out offers to users, charging merchants $99 per month plus five cents for each text message sent out.

In the nine months since it launched, Sundrop Mobile has been targeting the hospitality sector with its services. According to TechCrunch it will use the new funding to extend that to retail, convenience and grocery businesses.

In another round of funding for the m-commerce space, MobiCart, which has operations in San Francisco and Newcastle, UK, has picked up a $500,000 seed round. The company’s main line of business today is a free platform for developers to create m-commerce apps for Apple iPhones, which it launched last year. The company will use the funding to extend the service to other platforms — Android and iPad support are supposed to come online in eight weeks, with more platforms to come soon after. It also plans to add more commercial functionality to the platform, including barcode scanning, coupons and loyalty schemes.

For these smaller investments, it’s interesting to see startups continuing to go local when fundraising. MobiCart says that the lead investor in the seed round was the Finance for Business North East Angel Fund, which is managed by Rivers Capital Partners.

The round was led by General Catalyst Partners, with participation from existing investors Sequoia Capital, Hummer Winblad and NCD Investors.

The San Francisco company is the latest to provide a cloud-based advertising platform that lets marketers to create interactive ads that can be studied and altered in real-time so as to provide better engagement. Among Flite’s publishing partners are such names as LinkedIn, Forbes, Yahoo (NSDQ: YHOO), CBS Interactive (NYSE: CBS) and IDG.

“Online display ads have, for the most part, remained unchanged since they first came into existence more than a decade ago,” said Will Price, CEO of Flite.

A number of other companies agree. As display has made a strong recovery over the past year, more marketers are willing to look at it as a branding medium. It isn’t there yet, since “engagement” is still a rather nebulous concept (“Does it mean someone clicked an ad or just brushed their cursor over it?”). Now that the dollars are flowing into companies like Flite, there are going to be greater demands to get some clarity around engagement. And the companies that best define it will be the big winners, hence the amount of venture capital being directed at Flite and others.

HubSpot competes with a number of companies with similar offerings, including Eloqua and Marketo, although it says its customer base is substantially larger. The company claims 4,000 customers, up from 1,800 in October 2009 when it raised $16 million in a funding round. This round brings the company’s total backing to date to $65 million. All of its existing investors participated.

CEO Brian Halligan said the company had not planned to raise the additional cash but decided to do so in order to “double down.” Much of the cash, he said, would go toward research and development.

HubSpot is on track to post $25 million in annual sales, more than double last year’s total. Halligan said it was too early for the company to go public — but it does plan to do so eventually.

Here’s a video overview of HubSpot’s features:

Also participating were Sequoia Capital, Ram Shriram from Sherpalo, and Ron Conway from SV Angel, according to a blog post from Bump. Marc Andreessen will also join the board of Bump.

Bump has had a huge growth spurt in the last year. It currently has 25 million subscribers, adding one million in the last two weeks alone. The company’s iOS app lets users share photos, music, contacts, calendar events and text messages by touching their devices together. The company says a new android app with enhanced features is “in the works.”

Bump’s founders, David Lieb and Jake Mintz, say that traffic has increased five-fold in the last five months (via Mashable). They also say that of its 25-million base, some seven million are “active” (having used the app in the last 28 days).

Business model: At this point, the Bump app remains free, and the main focus is to continue to grow the user base and monitor how the app is used, but Lieb and Mintz say that the company has been approached by other companies like record labels to potentially work together to pass content on to users. There is also potentially a larger play in the m-commerce space, too: the app already has a function to let users transfer money to each other.

The company currently employs 15 people but is in the process of hiring more.

This year is kicking of with a lot of VC activity in the mobile space: in addition to participating in the Bump funding, Sequoia is also the lead investor in the $25 million round of funding at mobile payment startup Square, announced yesterday. Last week, Skype announced it was buying mobile video streaming and sharing company Qik: Andreessen Horowitz has large investments in both companies.

The current round of funding for Bump comes about 14 months after it raised $3 million in a round led by Sequoia.

The round was led by Sequoia Capital, and partner Roelof Botha — a former CFO of PayPal and early investor in YouTube (NSDQ: GOOG) — will join Square’s board.

The news caps off a bumpy year for the payment company.

Square faced a lawsuit over its main product, a credit card dongle that plugs into a smartphone to process payments by either merchants or customers. And the product itself had problems working on the iPhone 4, one of the key devices targeted by the company. And in June, company founder and CEO Jack Dorsey — one of the co-founders of Twitter — wrote a letter to early users to say that the company had to suspend shipments of their dongles to deal with credit risk and fraud issues.

Things finally looked like they were turning a corner in October, when the company finally launched its commercial product publicly. Since then, the company has seen between 30,000-50,000 business sign up for the service every month, according to COO Keith Rabois, who spoke to the WSJ. Square is not reporting the size of its overall customer base.

Mr. Dorsey, speaking to the WSJ, said the company will be using the funding to expand its staff — it currently employees 64 people — and “accelerate word of mouth” about the company. One of the key targets for Square are small businesses that currently do not process credit card transactions because of the fees involved. (Square takes a fee from each transaction but presumably it is significantly smaller than those levied by Visa and merchant acquirers.)

Square raised a previous round of $10 million, led by Khosla Ventures, in late 2009, which valued the company at $45 million.
