SeedFAST is a type of Advance Subscription Agreement (ASA). These are individual, simple, quick agreements for future equity in the company where investors pre-pay for shares that will then be allocated to them in the next funding round.

A SeedNOTE is a type of convertible loan note. Convertible loan notes (or just convertible notes) give investors debt in your company. This will then be converted into shares at the next funding round. Being in debt gives an investor more protection if things go wrong, and SeedNOTEs usually have an interest rate which your company pays to the investor.

When should I use a SeedFAST/ NOTE?

SeedFASTs and SeedNOTEs should be used as a bridge to a later funding round, that will usually take place within a year. These agreements are perfect for when you want to quickly take in a small investment and you don’t want to commit to a valuation and doing a full funding round. Use a SeedFAST for a simple investment. SeedFASTs are SEIS/EIS compatible. A SeedNOTE should be used when your investor requires more complex deal terms such as a return of capital.

When does the investor get issued equity?

The SeedFAST/ NOTE Agreement will convert to equity at the next funding round, when you raise above a preset qualifying amount, or at the long stop date, the date at which it will automatically convert if you don’t raise any more funds.

Are SeedFASTs SEIS/EIS compliant?

Yes. SeedFASTs are similar to convertible notes but they aren’t classified as debt and this makes them SEIS and EIS compliant. As long as you convert the SeedFAST to equity within six months of your investor sending you the funds. Read more about SeedFASTs and SEIS/EIS in this article.

When can investors claim their SEIS/EIS relief?

Investors can claim their SEIS/EIS tax relief in the tax year in which the shares were issued. This means that the investors won’t be able to claim their relief until the SeedFAST Agreement converts to equity.

Are SeedFASTs and SeedNOTES internationally accepted?

SeedFASTs can be used by companies anywhere in the world for UK-based investors. SeedFAST is similar to Y Combinator’s SAFE but specially created by our Legal team for UK investors. We also have versions for France, Singapore and Hong Kong. Read more on how SeedFAST works for international companies. SeedNOTEs can be used for both companies and investors anywhere in the world.
