Is it ever the right time to leave big pharma for a smaller biotech?

Company: Pfizer

Ten years at Pfizer.

Good territory, decent manager, reasonable comp.

But I'm watching friends who jumped to smaller biotechs 3-4 years ago — some of them are now in leadership roles, carrying equity that's actually worth something, and building deep expertise in one therapeutic area instead of getting remapped every 18 months.

Meanwhile I feel like I've been treading water.

Three restructurings.

Two product discontinuations.

One "strategic pivot" that moved me from CNS to cardiovascular against my preference.

I know the big company safety net is real.

I know biotech is riskier.

But I'm starting to wonder if the stability I'm protecting is actually just stagnation.

For people who made the jump: what did you wish you'd known beforehand? And for people who considered it and stayed: what made you stay? Looking for honest takes, not recruiting pitches.
