What We Do

We’re an early-stage venture capital firm that backs customer-obsessed companies and spearheads their communications.

We invest across industries from pre-seed to seed - and occasionally series A - make swift decisions, co-invest with leading VCs, and help grow your business through storytelling.

Inspired by Jeff Bezos’ Day One philosophy, our name reminds us to live every day and make every decision as if it is Day One. When we evaluate companies, we look for the Day One mentality and a culture of undeniable customer obsession.
