Fiscal Sponsorship

A nonprofit home for your project.

Mulvium lends your project its nonprofit home, so it can raise money, sign contracts, and grow—long before it is an organization of its own.

What is a fiscal sponsor?

An established nonprofit that takes a new charitable project under its legal umbrella.

The project becomes one of the sponsor’s own programs, and that one step changes everything. When the sponsor is a 501(c)(3) public charity, gifts to it for the project are tax-deductible, foundations can fund it, and its founders can begin the work now, instead of first spending months and real money forming a nonprofit of their own.

Mulvium’s nonprofit, The Mulvium Foundation, is meant to serve as that sponsor. It has not yet been formed or recognized as a 501(c)(3): before it is, we are hearing from the founders it would serve. Join the waitlist. Founders keep leading the work day to day; Mulvium carries the legal and financial responsibilities.

Starting a charitable project on your own, and with Mulvium as its fiscal sponsor
On your own With Mulvium
Getting started Incorporate, seat a board, write bylaws, apply to the IRS, and wait months for an answer. Begin as soon as the sponsorship agreement is signed.
Gifts Not tax-deductible until the IRS recognizes you. Made to Mulvium for the project, with receipts from Mulvium; tax-deductible once Mulvium is recognized as a 501(c)(3).
Grants Many foundations fund only recognized charities. Mulvium applies for and receives grants as the legal grantee.
Contracts & insurance Yours to negotiate, sign, and carry. You negotiate and recommend; Mulvium signs and arranges the insurance.
Books & compliance Accounting, filings, and audits are yours alone. Mulvium keeps the books and keeps the project within the rules for charities.
Building the institution Work it out as you go. An engagement lead and Atelier, the institution-building tool of MulviumSOS, help plan the programs, budget, and funding.

How does it work?

Money and responsibility move along one simple path.

  1. Donors Individuals, businesses, foundations, and public grants
  2. From donors to Mulvium: Gifts and grants From Mulvium to donors: Receipts and reports
  3. Mulvium Holds the project’s own fund, signs its contracts, and keeps it compliant
  4. From Mulvium to your project: Funds for approved expenses From your project to Mulvium: Plans and requests
  5. Your project Its founders lead the work
  1. Apply

    Tell us about the project. We confirm its purpose is charitable and that it is a good fit.

  2. Agree

    A fiscal sponsorship agreement makes the project a Mulvium program, with a fund of its own.

  3. Raise

    Donors and foundations give to Mulvium for the project. Every gift is receipted and held for the project alone.

  4. Build

    You lead the work. Mulvium signs the contracts, pays approved expenses, and keeps the books; an engagement lead and Atelier help plan the rest.

  5. Grow

    Stay under Mulvium’s umbrella as long as it serves the project. Funds raised for the project stay with its charitable purpose.

In plain terms

Gifts belong to Mulvium and are held in a separate fund for the project, spent only on its purpose, and never mixed with anyone’s personal money.

It signs, accepts gifts, issues receipts, and answers to regulators. Founders lead the work and recommend what it needs.

Like every fiscal sponsor, Mulvium charges a fee, set in the sponsorship agreement: 10% of gifts received. Founders are never billed for the work of building the institution.

2027 · A multi-day festival

The Beethoven Bicentennial Festival

2027 is the 200th anniversary of Beethoven’s death in 1827. This is the perfect opportunity to celebrate his universal, invigorating music in a unique way. The vision is to produce a multi-day festival featuring solo, chamber, vocal, and orchestral music, including intellectual discourse with scholars and students. The hope is to collaborate with the local community and invite distinguished musicians from around the world.

It needs venues · musicians · travel · sponsors · audiences

From there, Mulvium can

  1. Accept gifts, sponsorships, and grants for the festival, and send every donor a receipt.
  2. Sign the venue, artist, and travel contracts, so no founder signs personally.
  3. Hold the festival’s fund and pay musicians, halls, and vendors as expenses are approved.
  4. Arrange insurance for the concerts and keep the festival within the rules for charities.
  5. Draft the festival’s plan in Atelier: programming, budget, funders, and timeline.

One year · A research sprint

The Rare Disease Sprint

A child is diagnosed with a disease so rare that no laboratory in the world is studying it. There is no research to join, so the research has to begin. The vision is a single year in which everything a scientist needs to start is built at once: the patients’ genomes sequenced, cell lines grown from their samples, and a laboratory model of the disease—each made with partner labs, and each given away free to any researcher who asks. The hope is that by the end of the year, this disease will never be neglected again.

It needs partner labs · patient consent · sequencing · cell lines · a disease model · donors

From there, Mulvium can

  1. Hold the sprint’s fund and accept gifts from families, foundations, and the public, with a receipt for every donor.
  2. Sign research agreements with the partner labs, so every result is shared openly and none is held back.
  3. Pay for sequencing, cell-line work, and the disease model as each milestone is met.
  4. Make sure every patient and family gives informed consent, and that their data stay private.
  5. Draft the sprint’s plan in Atelier: milestones, budget, partner labs, and funders.

2 August 2027 · A festival of the sun

Six Minutes at Luxor

On 2 August 2027, the Moon will cover the Sun for more than six minutes over Luxor—the longest total eclipse on land this century, above the temples where Egyptians once worshipped the Sun. The vision is a five-day festival of learning that builds toward those six minutes: lectures by Egyptologists and astrophysicists, nights of desert stargazing, workshops for Luxor’s schoolchildren, and a student team that, during totality, repeats the 1919 measurement that proved Einstein right. Every event is filmed and edited into a series of educational films, released free to classrooms around the world.

It needs venues & permits · scientists · telescopes · a film crew · eclipse glasses · translators

From there, Mulvium can

  1. Accept gifts and education grants for the festival, with a receipt for every donor.
  2. Sign the venue, travel, equipment, and film-crew contracts, and secure the permits to film at historic sites.
  3. Give every schoolchild in Luxor certified eclipse glasses and a lesson on watching safely.
  4. Hold the rights to the films and release them free, with subtitles and lesson guides for teachers.
  5. Plan the festival in Atelier: programme, budget, partners, and timeline.

One day · A school’s farewell

The Last Lectures

After a century, a town’s old high school will close its doors. The vision is a final day of school unlike any other: every living teacher who ever taught there returns to their old classroom to give fifteen minutes on the subject they love most, with generations of alumni back in their seats as students. Every lecture is filmed and published free to the world, and the day’s gifts fund scholarships for the first class of the town’s new school. The hope is to honor what a school gave its town, and to keep its best teaching alive for everyone.

It needs the building · the teachers · alumni · a film crew · a scholarship fund

From there, Mulvium can

  1. Sign the agreement for the building’s last day and arrange insurance for the event.
  2. Contract the film crew, gather every teacher’s consent, and publish the lectures free.
  3. Accept alumni gifts with receipts and hold them in a restricted scholarship fund.
  4. Award the scholarships fairly, under a written selection policy.
  5. Plan the day in Atelier: the schedule, outreach to alumni, and the budget.
