ANN ARBOR – The Michigan Angel Fund invested nearly $3 million in six deals during 2015, including almost $1.6 million in the last quarter alone.

With 100 members, the Michigan Angel Fund  is the largest angel organization in Michigan and has 15 companies in its portfolio. The group funds companies that are seeking early investments from $250,000 to $2 Million.

The fund was established by Ann Arbor Spark, with administrative support from the Michigan Economic Development Corp., to help finance early stage companies in Michigan and to attract additional angel investors. In general, seed funding comes at the earliest stage of business formation. Series A is usually the first round of financing for a new venture after seed funding.

“MAF investments in these Michigan companies not only directly support our entrepreneurial economy, but also attract outside investment to the state,” said Skip Simms, MAF manager and senior vice president at the economic development agency Ann Arbor Spark. “Angel activity continues to expand throughout the state, with a growing number of investors committing themselves to funding the next generation of startups in Michigan.”
