Last week we reported that MessageMe, one of the latest messaging apps to hit the smartphone market, had picked up a $10 million Series A round of funding, and today, the company is officially confirming the news, along with some more details on how it’s been doing in the 2.5 months since it launched. It now has 5 million users across both iOS and Android — a five-fold increase on the 1 million that downloaded the app in its first 10 days.

MessageMe aims to carve out a name for itself by offering more ways than the rest of the pack — which includes WhatsApp, Line, KakaoTalk, Viber and Facebook (from which MessageMe gained some notoriety when it was restricted from using Facebook’s social graph API to find friends to use the app) — for users to communicate with each other on its messaging platform. In its case, this is done through notifications via text messages, but also pictures, doodles, video, voice, location and music sent from one user to another. Altogether, usage of these has risen three-fold, to 1,500 per second from 500 65 days ago.

From what we understand, although MessageMe is partly founded by people with extensive gaming experience — Arjun Sethi and Justin Rosenthal both worked together at social games company LOLapps (acquired by 6waves in 2011) — it will be messaging, not games, that will be the revenue driver for the company. Also: no plans to add in advertising, nor to charge for the app. Instead, it will build out premium messaging features such as stickers and money transfers.

When it comes to diagnoses and the possibility of undergoing serious medical procedures, we want second opinions (and trustworthy referrals) whenever we can get them. With 30 to 40 million Americans slated to receive insurance for the first time next year thanks to Obamacare — and with millions expected to experience higher costs and reduced coverage as a result — the system is in for a shock.

That’s why one Bay Area startup sees a huge need for trustworthy, affordable online resource for second opinions, and referrals. And, potentially, a huge business opportunity.

Conceived by Reputation.com co-founder Owen Tripp and chief of interventional radiology at Stanford Hospital, Dr. Lawrence Hofmann, ConsultingMD launched in early 2012 to streamline the diagnosis process and help patients connect with top specialists for speedy second opinions. In other words, it wants to be the “Mayo Clinic of the Web,” as The Wall Street Journal intoned in February.

MavenSay, a social recommendation app, just got a surge of unplanned downloads coming from Indonesia, and its founders are moving quickly to include Southeast Asia in its expansion plans, as a result.

The company’s Toronto-based co-founder, Jesse Dallal, said the two-month old app got 100,000 downloads over the past fortnight. It has a total of 130,000 downloads so far, and the sudden surge was tracked back to a power user based in Indonesia. They’re not sure which one it is, but the source of traffic points to the country, he said.

The way the app works is similar to Pinterest, in that users follow other users’ recommendations. These could cover places they’ve eaten at or music they’re listening to, for example. For its launch, MavenSay roped in what it called “influencers”—featured brands to follow such as Momofuku and Refinery29.

Real-time parking startup ParkMe wants to help find you parking — in real-time. The company, which originally started out on the Web, has been making a big push behind mobile apps, which is really smart, because most times when you’re looking for parking, you’re not on a PC, but you have a smartphone nearby.

There was just one problem — this app to find parking spots in real-time was only available on iOS, so there were a whole bunch of people who couldn’t use it. And their real-time parking finding powers were thus severely impacted. ParkMe is trying to correct that, with the release of an Android app that provides parking help to even the most helpless among those seeking to find a place to put their cars.

Android users will not only be able to find the closest parking for where they are now or where they happen to be going, but they’ll also be able to find the cheapest parking. And somewhere in between, maybe even the best value — the mythical “cheapest parking which is not so far away from their destination.”

HasOffers, a startup that helps mobile app developers see which ad efforts are actually paying off, is announcing that it has raised a $9.4 million round of funding led by Accel Partners.

The company was founded in 2009 — the product that it initially built, and the one that’s still highlighted on the HasOffers website, is a system that helps ad networks and agencies manage their performance-based programs. (Those agencies and ad networks include Bucksense, Tapjoy, and Sponsorpay.)

However, CEO Peter Hamilton said the team realized that mobile advertisers were facing a similar problem, so it built a product called MobileAppTracking, allowing developers to see where app installs, engagement, and purchases actually come from. So as publishers run ad campaigns, they can see which social networks, publishers, and ad networks are giving them the best results, and they can adjust their efforts accordingly.
