Values

Sphere Ventures aims to build a collective of ventures, investors, and coaches working together to drive change and innovation. We believe this is only possible by valuing and exemplifying the following principles

Sphere Ventures aims to build a collective of ventures, investors, and coaches working together to drive change and innovation.

We believe this is only possible by valuing and exemplifying the following principles

Ethical relationships require transparency

Openness is the force that allows integrity to take root, giving every interaction the clarity it needs to stay aligned. In this transparency, trust gains the space required to endure and strengthen.

Sphere Ventures places a high value on maintaining ethical relationships between collective members. We maintain a strict code of conduct, mandate minimum contact details, and define maximum equity gains to balance the power dynamic.

Growth starts with humility

A willingness to acknowledge limits opens the path for insight to take hold, allowing learning to progress with steadiness and intention. In this stance, feedback becomes fuel rather than friction, guiding development with clarity.

Sphere Ventures only works with people who are open to feedback and sympatico. We have a strict No Assholes policy.

Collaboration wins over competition

Shared effort becomes the catalyst for meaningful progress when contributions intertwine toward a common purpose. In this unity, collective strength outpaces individual ambition, creating outcomes no one could achieve alone.

Sphere Ventures is not just a collective of passionate individuals and teams working together to drive change and innovation; we also plan physical interaction to encourage networking and collaboration. We believe in the power of community.
