🚨 Update 🚨 Cinder raised $41M in Series B funding, led by Radical Ventures, with continued participation from Accel and Y Combinator. AI is already supercharging the efforts of bad actors to attack real people every day.

We started Cinder to make sure the people defending the internet have more firepower than the people attacking it. This funding means doubling down on what we can do for our customers, deploying AI agents at scale, and hiring people who want to do the most important work of their careers. The internet has always been abused. AI is making it worse. Cinder builds the infrastructure to fight back.​
