The unit economics of goodwill are notoriously inefficient. For every dollar donated, a nonprofit spends time and money on processing, receipts, and outreach, while the donor spends mental energy tracking it all. Dan Fitzgerald, a solo founder in Fort Lauderdale, thinks he can shrink that friction to a single tap. His company, Rosi Giving, is a mobile app that tries to be the operating system for charitable intent, bundling donations, social feeds, and corporate matching into one place [LinkedIn] [Google Play].
The wedge of the single receipt
The core of Rosi Giving’s proposition is administrative simplicity. The app lets a user give to multiple favorited nonprofits with one click and receive a single, consolidated tax receipt [Google Play]. It is a small, practical fix for a common annoyance. Around that transaction, Fitzgerald has built a lightweight social layer where users can track personal giving goals, earn badges, message friends, and follow updates from the organizations they support [Google Play]. The platform also has a B2B2C angle, inviting companies, clubs, and other "Giving Partners" to use it as a channel for coordinated campaigns or matching programs [Google Play].
A founder's story as initial fuel
Fitzgerald’s path to this startup was not through the usual venture circuit. After suffering a stroke in 2011, he experienced firsthand the power of community support during recovery. That personal story became the founding narrative for Rosi Giving, a project he started in 2020 [Visual Eyes]. The company’s early financial fuel came from FAU Tech Runway, a South Florida accelerator, which provided a pre-seed investment that brings Rosi’s total disclosed funding to approximately $70,000 [PitchBook, 2025]. The traction, for now, is the product itself, live on the Apple App Store and Google Play.
The crowded field of good intentions
Rosi Giving is entering a space that is both vast and fragmented. To succeed, Rosi must convince users to consolidate activity that currently happens across multiple dedicated surfaces.
- The payment rails. Platforms like GoFundMe or Facebook Fundraisers own the impulse donation moment within social feeds, but they are not built for recurring support or donor relationship management.
- The portfolio managers. Donor-advised fund (DAF) providers like Fidelity Charitable offer consolidated giving and receipts for serious philanthropists, but they operate at a much higher financial tier and lack a social, community-driven interface.
- The nonprofit CRMs. Tools like Bloomerang or DonorPerfect are the back-office engines for nonprofits themselves, focused on donor management rather than donor experience.
The math of making giving sticky
The back-of-the-envelope calculation for a platform like this is about activation energy. If the average donor gives to three charities a year and spends 15 minutes total on transactions and receipt management across separate websites, Rosi proposes to cut that to under a minute. The real metric will be the lifetime value of a user on the platform versus the cost to acquire them, a ratio that remains unproven at Rosi’s early stage.
