This is timely, as one of my very first angel investments back in 2015 announced this week they are going public. It's a kick ass company called @grovecollab and you can find an old podcast here...
This isn't a humblebrag tweet (every early investor has tons of losers and most startups will likely fail), but hopefully the blog and thread lets you know angel investing is practical at small amounts too. (My Grove investment was $5k at <$20m. Combined SPAC is $1.5B if final)
