Kagi has successfully raised $670K in a SAFE note investment round, marking our first external fundraise to date. This was made possible with the participation of 42 accredited investors, most of whom are actual Kagi users.

That is a dense paragraph.

1) What is a "SAFE note"? Google tells me:

    A "Simple Agreement for Future Equity" note is a way that startups can raise capital. The SAFE note is a legally binding agreement that allows an investor to buy a specific number of shares for an agreed-upon price at some point in the future, usually when the startup has a subsequent funding round.

2) What are "accredited investors"? Let's assume US.

SEC tells me: https://www.sec.gov/education/capitalraising/building-blocks...

    Net worth over $1 million, excluding primary residence (individually or with spouse or partner)

Or:

    Income over $200,000 (individually) or $300,000 (with spouse or partner) in each of the prior two years, and reasonably expects the same for the current year
