Popular kids' toy store Camp is begging customers for cash because its money is tied up in SVB. It's one of thousands of startups that now faces uncertainty.

• Experiential toy store Camp is caught up in the ripple effects of Silicon Valley Bank's collapse. 
• CEO Ben Kaufman said all of the company's cash was in the bank, so it's having a 40% off sale with the promo code "BANKRUN."
• Regulators officially shut down Silicon Valley Bank on Friday. It's the largest bank collapse since the 2008 crisis. 

Companies tied up in Silicon Valley Bank's orbit are feeling the sting of the bank's collapse.
