Artur Bergman founded the company in 2011 to build a content delivery network that developers could reconfigure in seconds rather than hours, with edge compute and instant purging as the differentiators. Customers include news sites, ecommerce, and streaming platforms that need cache invalidation at speed. A 2021 configuration bug took down a large slice of the web for about an hour, including government and media sites, which demonstrated concentration risk in the CDN layer. The company competes with Cloudflare and Akamai and is headquartered in San Francisco.

Equity comp at Fastly
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

A protective put caps your downside on the FSLY position at a chosen floor; a zero-cost collar pays for that floor by capping the upside. This calculator prices both structures off the current FSLY option chain, with annual cost, max loss, and tax-treatment notes.

Fastly equity questions
- How much does it cost to hedge FSLY stock?
- The cost of a protective put depends on how far below the current price you set the floor, how long the protection lasts, and FSLY's option-implied volatility. A zero-cost collar lowers that cost by selling away some upside. The calculator above prices both structures off the current FSLY option chain and shows the annual cost, maximum loss, and tax treatment.
- Does Fastly grant ISOs, NSOs, or RSUs?
- Equity compensation at Fastly typically takes the form of restricted stock units (RSUs). Restricted stock units are taxed as ordinary income when they vest.
- Do Fastly RSUs use double-trigger vesting?
- No. Fastly restricted stock units (RSUs) use single-trigger vesting: each tranche becomes yours as it vests on schedule, taxed as ordinary income at that point, with no liquidity event required.
