If you’re looking for birds of a feather with whom to flock together, Alexandria-based myRete has an app for that. And the cash is flocking to them, too.

myRete COO Stephen Smith is a man in need of caffeine: his wife just gave birth to identical twin boys last week. Wednesday, myRete will announce that its app WhosHere has over 1M active users. The Apple iOS app, launched in 2008, lets people with similar interests in an area find, text, picture-message, and make free WiFi-based voice calls with each other (we long for the challenge of a good Facebook stalking). A paid feature allows users to reach out to users in other countries. WhosHere drew attention from folks looking for a love connection, but it’s also caught on with others, like college students looking for people to practice their language skills. 

Stephen collecting his “hottest startup” award at the NVTC Hot Ticket Awards. He tells us the app has had over 3M downloads since its launch, putting it in the 95th percentile of iOS app sales. The company is also working on making WhosHere available for Android before the end of the year, a move that will double users, Stephen says. The bootstrapped company, which reached $1M in revenue in June, has no plans to raise VC. That doesn't keep VCs from calling, which Steven says is a regular thing now (reminds us of prom . . . well other people's prom).

Next on our Baltimore tech deal tour, we jumped across the Inner Harbor to the Canton Emerging Techology Center to check in with the team at 410 Labs: Chairman Matt Koll, CEO Dave Troy, lead developer Jonathan Julian and developer Nick Gauthier.  Yesterday, the company announced capping a $750k first round of funding. The web app company's backers include True Ventures, 500 Startups, Maryland Ventures, and Fortify Ventures, as well as individuals including LivingSocial's Tim O'Shaugnessy and former Blue Sky Factory CEO Greg. (Full disclosure: Greg and Dave used our phone to schedule their next meeting.)

Dave says 410 sought the funding to expand as its products get hot. The first, Replyz, a social Q&A service that plugs into Twitter, launched last year. But it's quickly being eclipsed in buzz by ShortMail, a web-based email tool that allows public conversations and integration with Twitter. Dave is one of the godfathers of Baltimore's tech mafia. After cashing in his ISP, Toad.net, in 2004, he became a self-described "serial entrepeneur." Dave was one of the founders of  the Baltimore Angels VC group and led the creation of the TEDX MidAtlantic speaker series. Now he's putting "110%" into 410 Labs. (Otherwise it would just be called 400 Labs.)

We also caught up with Delta Solutions CEO Tim Matlack Monday; he's at the Association of Government Accountants conference in Atlanta. His financial systems consulting company recently won several crucial re-competes, a huge sigh of relief for Tim. He came on board 18 months ago knowing that Delta would face stiff competition trying to win $66M worth of work. HUD re-hired Delta to keep its old financial system going while a new one gets installed. ($25M) The company is supporting the VA’s legacy financial system and its data warehousing and reporting capabilities ($11M). The National Park Service also tapped Delta to help implement its new financial management system ($12M). And Delta has an $18M contract with DEA to operate the agency's new financial management system.

Amazon's tablet is expected to ship 1M to 1.2M units in September, and IceWarp co-founder Ladislav Goc says his Springfield-based unified communications firm will be compatible with it. It’s a far cry from Apple’s 14M iPad shipment but ahead of other tablet launches. IceWarp says its users, which include Marriott and Verizon, will be able to sync e-mail, calendars, contacts, and tasks on the Amazon tablet. The company sells a corporate communications product for secure e-mail, instant messaging, voice and video for mobile devices. IceWarp spent a decade developing the service and has just started its marketing push.

Baby boomer business owners (say that three times fast) will continue making waves long past retirement. The McLean Group investment bank chair Dennis Roberts (author of Mergers & Acquisitions: An Insider’s Guide) observes that boomers own some 67% of middle market businesses and many are looking to trade their companies for retirement dreams. On average, about 35,000 boomer businesses should sell annually from 2011 through 2030—collectively generating some $3.3 trillion in value. (Here’s how Dennis puts all of this in perspective: 3.3 trillion hours ago takes us back to 150 million years before the first dinosaur appeared on earth.) Add that value of business acquisitions to the growth of technology businesses and we are likely to see a major surge in global mergers and acquisitions in the next 20 years. See, getting older isn’t so bad after all. Find more on The McLean Group (our sponsor) here.
