Frustrated with my Startup

I used to work at a product-based company, joined as a fresher worked for 2 years, it was a perfect job, in the sense that there was little to no work related stress, decent pay, and all the perks you get at a typical big product company as an SDE.

I decided to move out of my comfort zone and joined a bootstrapped startup. It sounded stupid when I left but I just wanted to experiment with working in a high-paced environment.

3 months in and I am very frustrated there is no sense of urgency even in a highly competitive space, all 3 co-founders are busy fundraising and rarely talk to us except for standups(which are also skipped regularly) most other team members(a total of 11) work like govt employees, no hunger, passion or curiosity.

I joined because I love the problem they are solving and I am genuinely passionate about the industry and problem space but I don't even see 10% of the same passion in any of my other teammates they come in at 10 and leave by 4.

Sorry for the long rant but need genuine advice, will things change after the fundraise and as an employee how do I raise my issues with company culture with co-founders without sounding too bossy and pissing off my other teammates.
