WHITE RABBIT We build cybersecurity companies with you. Most startups fail because they build the wrong thing and can’t rise above the noise. We stop that before it happens. We validate problems with real CISOs. Then we invest. Then we build alongside founders. White Rabbit is led by operators. Not advisors. Not tourists. Caleb Sima finds the problems. Nir Polak builds the companies. Early-stage cybersecurity. Hands-on. Validation first. If you’re building, or thinking about it: contact@wr.vc
