My experience is that there are a bunch of metrics about startups which correlate with the founders' skill/effort better (though not perfectly) than exit value:

1. Peak revenue run rate (and related metrics like EBITDA)
2. Prestigiousness of investors
3. Prestigious of incubator
4. Amount of money raised
5. Number of employees

And most of these metrics are publicly available.

I actually don't know a ton of people who are in the category of "founded something that was ex-ante plausible, put multiple years into it, but it didn't work out" so I'm mostly speculating, but my somewhat limited experience is that people will usually put on their resume stuff like "founded and grew my start up to $10M/year ARR with 30 employees backed by Sequoia" and this is impressive despite them not exiting successfully.^[1]

1. ^{^}

   Though obviously ~100% of these founders would happily exchange that line on their resume for a fat check from having sold their company.

I am obviously biased, but I do think that this post of mine is the most accurate thing I know of for predicting founder income.

80k's article is one of the few other things I know about; I think there might just not be that much written about this (although in fairness "startup earning to give advice" probably looks a lot like "startup advice", so maybe not that much actually needs to be written)

Thanks for the question! I tried to give my quick thoughts on this here.

My sense is that the companies which have managed to be impactful and profitable create products which require substantial capital investment but which are profitable while still having massive positive externalities if created. Importantly "we will create X, but after having created X we will go on to create Y and Y will be good for the world" seems to have a pretty dubious track record.

(I guess this is an elaborate way of saying "impact + profit" companies work if and only if there aren't market failures.)

I have a general bias in favor of focus and simplicity, which makes me think that people should usually focus either on EtG or impact but not both, but it's really hard to give universal advice here. I think if I were you I would just BOTEC out the value of the two products you are considering, and then do the one which has the higher number.

Unfortunately I can't disclose the acquisition price. I put donations into a DAF immediately after the acquisition, for tax reasons, but I think have distributed only ~20% so far. I also calculated that it was more tax effective to cut my salary than to donate to CEA and have that money go to my salary, so I did that (and didn't put some money into the DAF as a result).

Seems pretty good! My mental model is something like: 80% of the value of skincare comes from sunscreen + moisturizer, 15% from vitamin A, and then everything else is either speculative or has small improvements. Some things you might want to consider to further optimize the remaining 5%, if you want:

1. A relatively gentle exfoliant, 1-2x/week (used instead of the products you would normally apply). Alpha hydroxy acids are pretty popular and usually don't cause a terribly strong reaction (though you probably will be red for a day).
2. Vitamin C (in the morning), particularly if you have hyperpigmentation.
3. Microneedling has results that are roughly comparable to tretinoin, and additionally aids in product delivery (for the obvious reason that the needles poke through your epidermis). So you could consider this, although it's substantially more invasive than the other things on this list (while still being considered "minimally invasive").
4. The three products you mentioned have slightly different pH's; possibly you are already doing this, but consider spacing out their application (e.g. tretinoin at night, niacinamide in the morning).

I think HairToHelp.us is one of my favorites because it's actually been a slightly useful project – multiple people have changed their haircut as a result!

I've recently been interested in augmented reality effects, and hope to have more of them soon :)

This is a very broad question! I guess the major debate right now is whether one should focus on a "path" (a la 80k) versus a set of "aptitudes" (a la Holden). I slightly think that aptitudes is a more useful framework if you are very early in your career, but it feels pretty close to me.

By far the most important suggestion (unless you are optimizing for a very short timeline) is to wear sunscreen. Vitamin A (retinol, trentinoin, etc.) is the next thing I would add in if you are willing to do something every night in addition to every morning.

Regarding cosmetics: Unfortunately I don't have a great general resource; I do have a playlist of some of the videos which I made that seemed most useful to people. (Part of why I started making videos is that I couldn't find good resources for myself, but possibly that's changed in the past couple years.)

I don't recall any discussion of things like "is it okay to steal money if that goes to good causes?" and if you were to visit the AR office during the brief time I was there you would find a huge range of dysfunctions, but not people endorsing theft. (Note that I was there before any of the things people are charged with were alleged to have occurred.)

I hear a broader version of this concern sometimes from people who believe that finance or tech more generally are bad for society, and regardless of whether that's true my experience is that the rank and file people who work in those sectors are basically pretty average people who happen to like math or programming or whatever, and I wouldn't expect more value drift from you working with them than you would from working with the average person.

(I think there's a stronger concern like "the value drift you experience from working  the average person is too strong; I want to be surrounded by people who give 90% of their income, are vegan, etc." and if that's your desire then I do suspect that earning to give is probably not right for you.)
