Switch, this is too less as per 2023 sde salary standards. 20-36lpa is considered as a good pay.
Mardar chod increment is not based on YOE but your work towards company. Stop down grading Gainsight.
Switching is still a better option. It's not about yoe if you talk with your friends. A lot of companies have increments every 6 months. It's never been about down grading Gainsight. Gainsight is a really good company with amazing transparent leaders but you should not settle for less. Seems like you had a bad increment this time take care. I will say switch where your work towards company gets valued
For some reason I wasn't able to add in description so I added everything in the title
