Pre-IPO v. Public Tech Company Salary (I will not promote)

Would love to get input from this group (thank you in advance)! I don't have startup experience so hoping to tap into this group's expertise. I'm currently interviewing with a fintech startup that's pre-ipo (filed paperwork). The recruiter won't share what the total package would look like yet but the base/bonus (quarterly) is basically the same. It would also be the same title and similar work (so basically a lateral move). I'm trying to evaluate if it's worth pursuing this startup opportunity (particularly the financial upside). My guess is I'd probably be joining too late to realize any major financial gains. **Startup**: Pre-IPO, \~$200k, \~15% quarterly bonus, Stocks (TBD) **Tech**: Public, \~$200k, \~15% quarterly bonus, \~$100k/year (vesting quarterly) (I will not promote)
