Built with families, for family life

From a Reddit post to an AI operating system for families.

Founded by siblings Rasmus and Ida Stjernström, Famnest is building a privacy-first Family OS that brings finances, bills, calendars, documents, health records and everyday household responsibilities into one place, with AI that can understand the family as a whole.

386 families interviewed before launch
10k+ downloads in just over two months
84% said Famnest helped them feel more in control

It started with a Reddit post.

We shared the idea publicly on Reddit before building. Community feedback became the first input into the product, setting a build-in-the-open approach from day one.

Ideation

386 family interviews.

We interviewed 386 families about how they manage money, responsibilities and decisions together. The clearest signal: families wanted their information connected, not another standalone tool.

Research

We went where families were.

We went beyond our online audience, meeting families through local communities, flyers and football matches to make sure the product was shaped by a broader range of real households.

Community

Families told us Famnest was changing how they felt.

In a survey of 5,340 users, 84% said Famnest helped them feel more in control of their finances and 79% said they felt more financially confident.

Impact

Mary, our free AI assistant, launched.

We launched Mary, our free AI assistant for accessible budgeting and financial guidance. With household context, Mary can answer questions, organize information and help families take the next step.

Product

Growth accelerated.

Commercial traction followed engagement: revenue grew about 70% month over month, accelerating to roughly 125% in the latest month, while growth remained highly efficient and largely organic.

Why it matters

One trusted place for the whole household.

Most products see one person, one account or one task. Famnest is designed around the family as a whole. By connecting finances, planning, documents, health information and household management, Famnest can give families more relevant support today and create the foundation for a proactive household agent tomorrow.
