Our flagship accelerator that started it all

Back in 2010, 500 Startups set out to create a 4-month long accelerator program for early-stage startups in Silicon Valley. After moving the program to downtown San Francisco and most recently opening up applications on a rolling basis, we continue to offer founders the opportunity for a $150,000 investment and a full program focused on growth and scaling their startup.

What do startups get out of the program?

build a founding team


Starting a company is solitary and challenging. Working with other people going through the same challenges makes a huge difference. Founders who’ve gone through our program tell us that the 500 community is extremely valuable.


Starting a company is solitary. Working with your peers going through the same challenges makes a huge difference.


500 brings in a wide variety of experts focused on marketing, culture, startup accounting, product design, sales, finance, and more. Think a Startup MBA on steroids.

Hands-on Support

We’ll work together on your business and product strategy, growth metrics and investor pitches.


You’ll have access to 1,000+ founders, 200+ mentors and our own staff. Thanks to our massive network, startups build relationships and partnerships that wouldn’t be possible at their size without 500. Need an intro to a customer? Early access to a new platform feature? API access blocked? Stuck at the border? We have connections.


Being a 500 Global company will validate your business, and our network will help you connect with investors when the time is right. 500 Startup’s standard accelerator deal is a $150,000 investment in return for a 6% stake. We charge $37,500 to participate, but the fees can be deducted from our investment.
