Our Approach
EarthShare provides fiscal sponsorship to bold, visionary projects advancing climate and environmental solutions. Our role is to handle the administrative, financial, and compliance responsibilities so leaders can stay focused on their mission and impact.
We support two proven fiscal sponsorship models. Every project begins with a thorough review of its mission, goals, and activities to ensure alignment and determine the best path forward. Based on this, we recommend the model—Comprehensive (Model A) or Pre-Approved Grant Relationship (Model C)—that best supports your work.

Frequently Asked Questions (FAQs)
Fiscal sponsorship is an arrangement where a nonprofit like EarthShare extends its legal and tax-exempt status to mission-aligned projects and initiatives. This allows individuals or groups to receive charitable funding and operate without forming a new 501(c)(3).
If your project aligns with EarthShare’s environmental mission, fiscal sponsorship may be a great fit. It’s ideal for changemakers who want to launch quickly, access funding, and focus on impact—without the overhead of incorporating and managing a new nonprofit. We’re built for leaders who value flexibility and trusted support.
It depends entirely on the needs of your project. Whether your project is better served as a Model A or Model C project is determined by the type and amount of support you need. See our breakdown of fiscal sponsorship model types here.
It depends on the ultimate goal of your project. You can remain a fiscally sponsored project indefinitely (or until your project comes to a natural close), or you can work to build your administrative, financial, and legal capacity while a fiscally sponsored project with the goal of incorporating a 501(c)(3) organization in the future.
It is best to identify funding prior to seeking a fiscal sponsor. Due to the cost of onboarding new projects, most sponsors prefer a project to have a minimum amount of committed funds already, whether from foundations, individual donors, or corporate sponsors.
While EarthShare does not provide funding or direct fundraising assistance, we do offer feedback on grant proposals as well as donor communication support and reporting. Networking with other projects in our portfolio can also help identify new opportunities for your project.
It typically takes 3-4 weeks for EarthShare’s team to fully review your project’s application and provide formal approval. From there, the onboarding process can begin, the timing of which largely depends on the size, scale, and complexity of your project.
EarthShare applies an administrative fee ranging from 6% to 10% based on the project type (Model A or C), program scope, budget, and level of services provided. A fee estimate will be determined early in the application process.
We provide HR support for hiring both U.S. and international employees and contractors, including payroll, benefits, and compliance. From onboarding to benefits management, we offer the HR tools and resources to help build and support your team every step of the way.
Yes, absolutely. EarthShare supports projects at every stage of their growth. If and when you’re ready to incorporate a new 501(c)(3) or transfer to an existing 501(c)(3), we’ll help you plan and execute a seamless transition—providing guidance, financial reporting, and assistance with transferring all remaining project assets to help ensure your long-term success.
