Two people.
A shared
commitment.

We’re the co-founders behind Cirro: engineers and independent operators building for Solana.

Both of us build the tools, shape the products and run our infrastructure. Our roles bring complementary business and technical perspectives to the same work.

Where we operate
matters.

A decentralised network needs independent people behind it.

Both Cirro co-founders live and work in South Africa. We bring that perspective to our engineering, our relationships and our responsibility to a global network.

Our conviction is simple: open participation, independent operation and a Solana that works better for everyone.

LOCAL ROOTSGLOBAL RESPONSIBILITY
01 / INDEPENDENT OPERATION

More than a node count.

Many validators under one operator still share a point of control. We make our own operational decisions and take responsibility for our validator.

02 / DISTRIBUTED STAKE

Voting power, spread wider.

Broader stake distribution supports resilience. We want independent operators to remain a meaningful part of Solana’s consensus.

03 / OPEN PARTICIPATION

A network for everyone.

Builders and operators should be able to contribute from anywhere. We stand behind the permissionless principles that make that possible.

Working toward a stronger Nakamoto coefficient.

The measure counts the validators needed to reach more than one-third of voting stake. Our focus is on the foundations behind it: independent operation and less concentrated stake.
