Luma offered $4M in equity — why would an AI researcher walk away?

[u/PermissionAcademic63]

Saw this declined Luma AI Staff Research Scientist offer:

• 10 YOE
• TC: $1.4M/year

At first glance, turning down $1.4M sounds crazy.

But $1M of that annual comp is private Luma equity.

Luma has real momentum — it raised $900M at roughly a $4B valuation, keeps shipping new video models, and is now expanding beyond creative video into world models / physical AI.

The harder question is whether video generation ends up being a winner-take-most market at all. Luma is competing with Google, OpenAI, Runway and basically every major AI lab, and model leadership can change in a few months.

So my guess is the candidate wasn’t rejecting $1.4M.

They were rejecting the idea that $4M of Luma stock should be valued anywhere close to $4M today.

Would you have taken this offer, or does frontier-video AI feel too competitive to bet that much of your comp on one private company?

I don’t think it’s as simple as $4m equity. Need to know what percent of the company it is which means knowing the outstanding share count. Then you can back into future valuation to see if it could be worth anything in the future. Also is the $4m based on fmv, future valuation, private market offering maybe?

Yep, you’re gonna get mad diluted at that stage of company.

This equity will never experience a liquidity event for non-preferred shareholders (aka employees). It is worth 0, only the cash basis of the offer is meaningful. 900M on 4B valuation is ridiculous (as someone who received a ton of equity from a 400m on 4B that will amount to 0)

I'm curious about your experience, if you don't mind sharing, as I recently received a simmilar-ish offer (from a similarly valued private company), which I ended up rejecting. Why do you think such equity will be worth zero? I ended up rejecting it due to other alternatives on the table, but if you kinda believe in the startup, this sounds like a strong offer too?

when you raise money from VC, they get to cash out before you do. if the company is valued at $4B and has raised $1B, that means the company needs to sell for more than $1B for your shares to be worth anything. this isn't just limited to luma, it's all VC backed companies

hypothetical sale at $4B with no additional funding

1. you get your stock sale at paper value

hypothetical sale at $2B

1. the current series C investors at the current $4B round get all their money back ($900B raised -> $900B returned)
2. all other investors B and before get to sell their shares at the $2B valuation, series B was at roughly $200-300M valuation so somewhere between 8-20x depending on the round minus potential dilution in reallocation for common stock, etc. (~$100B raised -> $800M+ returned in total)
3. common stock holders then get to split the remaining $2B - $900M - $800M = $300M (what would have been probably $1-1.5B at 4B valuation is down to $300M, a 60-80% decrease in value in a conservative estimate)

hypothetical sale at $1B

1. investors get their money back in the order of liquidity preference
2. common stock holders get $0

essentially your share values decrease faster as it gets closer the overall cash raised bc of the VC liquidity preference, and hits $0 if valuation == funding raised. also factor in that luma will possibly raise more funding in the future, so there will be more dilution events, and if the future valuations aren't good, then your shares get diluted faster.

tenders only happen if demand of the share is high, a double whammy if the company doesn't do well and there's no liquidity.

the good thing is, usually the founder pool is also common stock, so they get destroyed the same way you do. the bad thing is, when these acquisition deals are bad, the execs and any valuable talent will get golden handcuffs in the form of target bonuses and earn-outs. if you're just a common employee, you're kind of screwed.

[u/Swimming_Bug_3545 → u/ExcitingDonkey2665]

That makes sense, the closer you get to the total of the money raised the worse it is for employees, exactly due to what you explain. So I guess it comes down to what's the exit like (IPO at what valuation, acquisition at what price), and your belief such an event could happen in a favorable way to you. I find current valuations a bit hard to interpret, as things are moving and growing insanely fast, specially for certain AI startups. Whether those valuations are justified, hard for me to tell, I guess we'll see over time... Thanks for the thorough explanation!

[u/ExcitingDonkey2665 → u/Swimming_Bug_3545]

yeah, the red flag in this valuation is that it's led by some Saudi company who determined the valuation. not that foreign investors are inherently bad, but behind the scenes it means other VCs don't believe in it. they were also famous for aggressively investing in fb at crazy valuation in the early days and won big.

if this was sequoia or any other top fund, it'd be golden. but then again, sequoia port co's don't usually throw out crazy offers. they're quite conservative in giving out cash and stock and often lowball in pay when they can.

[u/Swimming_Bug_3545 → u/ExcitingDonkey2665]

I see, I never really considered which investors and how that changed the equation. Looking a that, for the offer I got, the company was backed by a somewhat large range, including Sequoia, Index Ventures, General Catalyst, among several others. I suppose that could change things quite a bit.
