# Eric Wiesen

> Eric Wiesen is a General Partner at Bullpen Capital, a San Francisco-based venture firm specializing in post-seed and early-growth investments. A two-time founder, former corporate attorney at Fenwick & West, and ex-General Partner at RRE Ventures, Wiesen brings a rare trifecta of legal, entrepreneurial, and investment experience to backing companies that don't fit the standard seed-to-Series-A mold. His track record includes exits through Braintree/PayPal ($800M), Venmo, Makerbot, and TapCommerce, and he's known for hunting non-obvious, non-consensus opportunities where value is obscured from the investment herd.
