Cashstack is a beautifully simple social giving platform built around a single, powerful idea: the moments when we are most surrounded by people we love are also the best moments to give. Whether it's a dinner party, a team celebration, or a family gathering, Cashstack turns that joy into collective generosity — right then, right there.
The platform works in four steps. A host creates a Cashstack in seconds and shares it with their group. Everyone joins using a simple code, sees the cause the host has chosen, and swipes a playful slider to commit what they can — as little as $1. The stack grows in real time as contributions come in, and once the gathering is complete, the collected funds are made into a single donation directly to a highly-rated nonprofit. Simple, joyful, and impactful.
What makes Cashstack fundamentally different from conventional donation platforms is its group-first architecture. Giving is not a solitary, transactional act — it is a shared moment. Everyone in the room sees the total rise together, which creates the kind of collective emotional resonance that individual donations never achieve. A few dollars from twenty friends stacks into something real.
Trust is built into the model through the Master Stacker system. The host who creates the Cashstack takes the Master Stacker Oath — a commitment to responsibly collect and submit funds to the chosen nonprofit within 7 days and share the receipt with the group. Cashstack never handles money directly; the group is the trust.
Cashstack supports a wide range of causes including Disaster Relief, Hunger & Food Security, Children & Youth, Veterans & Military Families, Health & Medical Research, Animals & Wildlife, Education, Environment & Conservation, Housing & Homelessness, Mental Health, Arts & Community, and Seniors & Caregiving. And critically: 100% of every dollar goes to the cause — Cashstack charges no fees and never sells user data.
ARTE LOGICA is proud to partner with the Cashstack team to help build and scale the technology that powers this vision of joyful, collective giving.
