Does an MFN clause apply automatically?

Usually it requires election. The holder receives notice of the new instrument and elects whether to take the new terms. Election is typically irrevocable. Some MFN clauses are auto-applying, but those are less common.

Does MFN protect against down rounds?

Partially. MFN protects against worse terms in the same instrument class (e.g., SAFE-to-SAFE). It doesn't protect against priced rounds with lower valuations — that's what anti-dilution protection is for.

Are MFN clauses standard in SAFEs?

Increasingly, yes. They were rare in early SAFEs but are now common, especially for investments above a certain threshold.

MFN clause (Most Favored Nation)

Clause entitling investor to receive any better terms offered to subsequent investors.

Definition

A Most Favored Nation (MFN) clause is a contractual provision granting an investor the right to receive any more favorable terms that the company subsequently offers to another investor in the same instrument class. Common in SAFEs and convertible notes, where it ensures that early investors aren't penalized when later investors negotiate better terms.

Same concept, different names

Universal	Contractual; in SAFE, convertible note, or side letter

How MFN works

An investor with an MFN SAFE invests at a $5M cap. Six months later, the company issues another SAFE at a $3M cap to attract more capital. The MFN clause kicks in: the original investor's SAFE cap is automatically reset to $3M (the better term).

MFN typically applies only to the same instrument class (SAFE-to-SAFE, note-to-note)
MFN can apply to all economic terms, or only specific terms (cap, discount, conversion)
MFN must be invoked — the holder typically gets notice of any new instrument and elects whether to take the new terms

Why companies push back

MFN is investor-friendly. From the company's perspective, it constrains future fundraising flexibility — if the company wants to raise on different terms (say, a lower valuation in a down market), all MFN holders re-set to the new terms, which can blow up the cap table calculation.
