Rare Breed Ventures Case Study


With early meaningful cash upfront, wraparound services to increase capacity, and institutional knowledge, RareBreed aims to accelerate a company’s growth at the earliest stages.


McKeever “Mac” Conwell II, is the founder and managing partner of RareBreed Ventures (RareBreed), a pre-seed stage venture fund based in Baltimore, Maryland. Previously, he was a seed-stage fund manager at the Maryland Technology Development Corporation (TEDCO), software engineer, and two-time founder. RareBreed invests early in founders outside of the large tech ecosystem of Silicon Valley, New York, and Boston.

In September 2020, Mac left TEDCO to launch his first venture capital fund and structured it as a 506(c) fund. He primarily built his LP network from scratch by publicly marketing RareBreed on Twitter. In Q1 2022, he closed $10M for Fund I with the support of Alpaca VC, Carta, Insight Partners, Plexco Capital, and a number of individual LPs. He plans to launch his second fund at $75M+ later in 2022.

Why a 506(c) fund?

The 506(c) fund enabled Mac to more quickly launch and accelerate fundraising for his $10M pilot fund than he would have with the more traditional and expensive 506(b) fund. He leveraged his Twitter community — 20K followers at launch and 75K in June 2022 — as a catalyst to raise his fund with 80% of LP capital coming from Twitter connections. The 506(b) approach would have restricted his ability to publicly market his fund and deals and required larger upfront costs to pay for institutional fund service providers.

However, it was not an easy fundraising journey at all for Mac. During the first year, he had 1K+ meetings and upward of 25 meetings per day.

Investment Strategy

RareBreed is a pre-seed fund that invests in underrepresented founders outside of large tech ecosystems, earlier than everyone else. RareBreed takes a concentrated portfolio approach by writing checks from $50K to $250K as the first or one of the first investors.
