Cornerstone VC

Rodney Appiah and Edwin Appiah serve as co-founders and managing partners, jointly leading the investment committee. Their partnership blends Rodney's background in finance and private equity with Edwin's operating experience. Day-to-day sourcing and due diligence are supported by a lean investment team and leveraged through the Cornerstone Partners angel network.

The firm operates a unique dual structure where a formal venture fund sits alongside Cornerstone Partners, a community of over 100 Black professionals trained as angel investors. Members include lawyers, bankers, and startup operators who refer founders from their own networks. This creates a sourcing pipeline that reaches communities and founders typically missed by standard venture scouting.

Cornerstone VC makes direct equity investments into startup companies, primarily at the pre-seed and seed stages. There is no public record of the firm making fund-of-fund commitments or investing as a limited partner in other venture capital vehicles.

The firm targets the earliest check in a company's lifecycle. This includes pre-seed rounds where the product may still be under development and seed rounds where initial traction is being established. The firm has stated publicly that it aims to be the first institutional investor in its portfolio companies.

Cornerstone Partners is a legally separate angel network and educational platform also founded by Rodney and Edwin Appiah. It trains professionals to become angel investors and syndicates capital into deals. Cornerstone VC operates as the regulated fund manager, and the two entities share a thesis and sourcing network but maintain distinct legal and governance structures.

The firm describes itself as sector-agnostic within technology and has not published a formal exclusion list. Public disclosures indicate no known investments in heavy industry, hard science, or sectors requiring deep technical capital expenditures, which aligns with the firm's pre-seed software focus.

The British Business Bank committed to Cornerstone VC's fund through its Enterprise Capital Funds (ECF) programme, which backs first-time and emerging venture fund managers. The ECF programme matches private capital with government funding under specific terms designed to catalyze institutional backing for underrepresented managers.
