Early Stage Venture Capital Fund

Apertu Capital is an early-stage fund that invests in startups launched out of open source projects. A typical portfolio company builds on top of the founder’s open source platform to develop a SaaS business. The founder’s open source software is often used by large companies as a crucial part of the software process or critical infrastructure. Because of our experienced team and our history of working with startups, founders trust us for advice on building a business around innovative software. This access provides us an advantage when capturing value and driving returns for our investors. 

We prioritize opportunities where our founders demonstrate rare talent for pushing the margins of software innovation. Our deeptech investments improve programmer productivity and solve the hardest problems outstanding in software. 

A Call to Founders!

Apertu is the imperative form of the Esperanto word aperti. Whereas aperti means “to be open,” apertu commands the listener to “Open!”

In the context of Apertu Capital, apertu represents a call to startup founders, asking that they formulate companies around the free software projects they love. To us, freedom extends to software, which is why we believe that open source is critical to accelerating and democratizing our progress as a collective society.

Our fund invests in founders who have pioneered and now lead prominent open source communities. When founders are ready to take the transition from an open source project to a fully-functioning company, we will step in and assist the founders in developing the business model and strategy around their innovative software.

Opportunity That Includes

To us, the idea of apertu demands equal access and opportunity. We believe that underrepresented populations must be included in the tech industry to provide a channel that will increase equity in society.

As a result, we will invest a portion of the general partners’ returns in a platform that offers tech jobs and salaries to talent from underrepresented populations. This program installs new talent in fellowships committing open source code to established projects. 

Apertu Capital wants to launch new professionals into rewarding careers in software.  Spending a year of directed work writing publicly available code, paid at market rates, will set the foundation for these professionals to succeed.
