I got job offer from small lending bank with 62% hike , what to do next?

The bank is small and lends money to small SME but is consistently making profits . It gave me a 62% hike to develop AI platform in their org.

It has 3.9 glassdoor rating

I accepted offer and moved out of a big org where i was doing mediocre work but creating AI platform but it was stable in this layoff season.

It has 90 days NP

And puts my salary way above market standards.

I wanted to develop platform in small orgs so I can learn everything, it aligns but i am scared of job security.
