I was once offered a job with a good, but not great, salary in a geographic region that was lite on IT jobs to which I would have to move.
The plan was for them to sell to a larger company in 2 years at which point any sane buyer would move this remote facility to their HQ.
Based on my equity and they're target sale price I would gross 40k from the sale, IF it ever happened.
No thanks. Maybe 20X that would have made it worth while since I'd be losing about 100k a year in total compensation.
In my experience, very few people have a similar life style to mine, which is to say, complicated. And when explained, most people don't understand how or why I would live like that.
At the time I was making around 200k consulting and those were 40hr weeks.
To take a job at a "startup" that was mature enough to pay me 120k salary but too mature to give me significant equity meant that if all went to plan I would get 120+120+40=280. On top of that I'd be working grueling startup hours.
Vs. 200+200=400 and taking it easy.
The appeal was that the job was in a coastal town where I wanted to live. There are very few IT jobs in that area.
Fast forward 8 years later. I live in the area I wanted, but I had to bank consulting money and gain experience to get to where I can work remotely and still demand a good rate.
They were surprisingly open and honest about the raw numbers and then somewhat stunned when I did the math right then and said "That's not much".
I am really puzzled about your perspective on job-hunting decisions, such that you see this, and nothing else, as the relevant context which would allow any of us here to give you useful advice.
Also, if they need you badly enough, make sure to include provisions that if an acquisition event occurs or your role changes materially from what you agreed to, your remaining options vest immediately.
Of course it's a gamble since the company might not be worth anything..
Is the broader industry/niche they serve growing?
