Entrada Ventures is a seed stage fund started by passionate, experienced operators and investors who have built multiple successful companies. We don’t just write checks. We work personally with a few companies each year helping them develop from startups with product-market fit to strong businesses ready for their first round of institutional financing. By investing in and working with strong founders who’ve demonstrated some traction, we can significantly improve those companies’ ability to understand, manage, and scale their business and raise a tier-one Series A on great terms. Entrada Ventures is based in Santa Barbara and Silicon Valley, CA, and invests across a broad range of innovative enterprise and industrial technologies. We are interested to hear from you, but please dont submit business plans or ideas to any of our partners via LinkedIn.
