Proving source of funds when your startup is pre-revenue

Before there is any revenue, the money in a startup comes from somewhere personal: founder savings, an angel cheque, or friends-and-family support. When a provider asks you to show where that money came from, it can feel like being doubted. It usually is not.

This guide is general information on what source of funds means at the pre-revenue stage, why it gets asked, and what providers typically request when there are no signed clients yet.

Why providers ask about source of funds

Asking where money comes from is a standard part of how regulated providers operate. It is not specific to you and not a sign that anything looks wrong — it is a routine check applied across the board.

For an early startup the question is simply: this company has no revenue, so where is the money funding it coming from? A clear answer to that turns the question into a quick formality rather than a back-and-forth.

Funded from your own savings

Bootstrapping from personal savings is one of the most common pre-revenue stories, and it is straightforward to evidence. The aim is to show how you came to have the money and how it reached the company.

Providers typically ask for something that connects the money to a legitimate origin — for example records showing accumulated savings or income, and a clear trail of the transfer from you into the business as a founder contribution or loan. Keeping that movement clean and documented from the start makes this easy to show later.

Angel or friends-and-family money

When the money comes from other people, the focus shifts to who they are and on what basis they invested. As general guidance, providers commonly look for:

  • Who the investors are and their relationship to the company.
  • The basis of the investment — for example a signed agreement, a SAFE, or a simple loan or contribution arrangement.
  • A clear record of the funds arriving into the business.

Having the paperwork for each contribution, however small, keeps the picture clean. Informal friends-and-family money handled with no documentation is the part that tends to raise follow-up questions.

What typically counts as proof

Exact requirements vary by provider, but at the pre-revenue stage the documents commonly requested include some combination of:

  • Records showing the origin of the money — for example savings or income history for a founder contribution.
  • Investment agreements, SAFEs, loan agreements, or grant award letters.
  • Records of the funds moving into the company.
  • A short, consistent explanation that ties these together into one story.

The thread running through all of it is consistency: the documents should agree with each other and with what you say about the business.

Showing the business is real with no signed clients

With no revenue and no signed clients, you cannot point to contracts — but you can still show a real, operating business. Reviewers look for substance beyond the bank balance.

Things that help paint that picture include a clear description of the product and target customers, a website or product in progress, founder backgrounds, any pilots or letters of intent, and a simple sense of the plan and how it is funded. None of this needs to be polished; it needs to be concrete and consistent with the rest of your application.

Frequently asked questions

It is a routine check that regulated providers apply to everyone, not a sign something looks wrong. For a pre-revenue company it simply asks where the money funding the business comes from.

Providers typically want to see how you came to have the money, such as savings or income records, plus a clear trail of the transfer into the company as a founder contribution or loan. Keeping that movement documented makes it easy to show.
