Ill-Wash-8606's journey

I'm currently working at a startup where I enjoy a good environment and have nice colleagues. I'm on a contractor setup with a decent salary, but the future feels uncertain. We've recently pivoted, are still searching for product-market fit, and there's no new revenue coming in. The company has about six months of runway left, and the board isn't sharing much information, which makes me feel uneasy about my job security. I've received an offer from a large, well-established B2B SaaS company. They are profitable, with millions in annual recurring revenue, and they are growing. The role is the same level as my current position, but it's in a different industry, and I see a real opportunity to learn new skills. The downside is that the salary is about 15% lower than what I currently earn, there’s no bonus, no clear progression plan, and it would also be a contractor position with a six-month probation period. I'm weighing the decision of leaving a comfortable but shaky startup for a less comfortable but more stable enterprise role. I know that runways can run out quickly, and I don't want to be job-hunting when layoffs happen. However, taking a 15% pay cut without a clear path for advancement is tough to digest, especially since I won't be stepping up in seniority. I'm looking for advice from anyone who has faced a similar situation. Would you take the leap?
