When I left my last company I asked for a 30% raise and my new company basically said "you didn't ask for enough" so they started me higher than my asking salary. Snce then they've given me raises twice a year and each time it's been 7% whereas my old company did 3-5% a year. I will never be undervalued again.

It feels scary but once you make the jump you won't have any regrets.

Go to the new company, do a killer job, and advocate for yourself.

Good luck!
