Another busy week for investors and companies looking to expand has come to a successful end. Starting a new business is typically challenging, especially when it comes to raising money to fulfill an important milestone.  Usually startup entrepreneurs secure funds from family, friends and mostly from their own funds when they start. Angel investment is a common second round of financing for start-ups. Venture capitalists are approached for larger funds.

Most large firms usually hunt for technologies and talent to boost their offering and products and this week was no different for search giants like Yahoo and software companies like McAfee. Yahoo acquired two startups but will shut them down because it needs just the mobile talent behind those startups. McAfee is paying $389M for firewall products which is understandable because McAfee develops software security products.

These are the 13 startup funding and acquisitions we spotted this week.

1.  Yahoo acquired two companies–Milewise and GoPollGo–both companies will be shut down whilst employees join Yahoo mobile team. Financial details of the two, separate transactions were not announced. GoPollGo is  a real-time polling tool that lets brands and media properties collect and analyse feedback whilst MileWise is a flight rewards app.

2. NetSuite  acquired OrderMotion, a developer of software used for B2B and B2C billing, ordering, and fulfillment. Financial details of the acquisition were not announced by the company.

3. Eleven-month-old startup Coinbase  raised $5M in a venture capital funding round. According to WSJ it’s the largest funding round to date for a Bitcoin startup. The $5 million investment was led by Union Square Ventures.
