Spiritual wellbeing is a basic human need.
We’re building for it, starting with online group prayer.

The Research

In progress

The 2026 Bay Area Online Prayer Study

We’re interviewing 25 Bay Area congregations about what they’re doing online and what is and isn’t working. Participants get the findings before they’re published.

Who we are

Joy Banerjee

Product and engineering. He previously built tools for distributed teams, and he’s the one who stays up late thinking about what a prayer request feels like to the person receiving it. He lives in San José with his family and a small, opinionated dog.

Tim Bonnemann

Longtime community architect with 20+ years experience in the private and non-profit sector. Passionate about connecting people around shared purpose.

Get in touch

We read everything, and we’re especially glad to hear from people running prayer in a community — whatever the tradition.

Making sense of the world together, rather than alone, is something people have always done. The forms vary enormously — across traditions, languages, and continents — but the need underneath doesn't. People still face things they can't resolve on their own, and still turn to each other to carry them. We're reminded of that daily. Mount Umunhum rises south of San José, in view from where we work — sacred ground to the Ohlone for thousands of years, and a reminder that what we're building is much older than we are. What's changed is that many communities and families are now spread out, across time zones or just across schedules that no longer line up. The tools are new. The need they serve is not.
