Matchstick Ventures, a seed-stage firm that says it invests in “rapidly growing, yet underserved startup ecosystems,” announced this week that it has raised $30 million for its second fund. That’s a lot more money than the firm’s $5 million seed round. This time, Matchstick says it will write initial checks of around $500,000, and in some cases make follow-on investments of $1 million or $2 million. The firm’s partners, Ryan Broshar and Natty Zola, are based in Minneapolis-St Paul.
