### Approach
Altimeter employs a crossover investment model, treating public and private markets as a single pool of capital. The firm focuses on technology, utilizing a concentrated, fundamental-driven approach where it makes high-conviction bets rather than following index weights. It actively invests in both early and later-stage private companies and manages a long/short public equity hedge fund, often positioning itself around major technological themes like artificial intelligence.

### History
Altimeter Capital was founded by Brad Gerstner in 2008 during the global financial crisis with initial capital from friends and family. The firm gained early recognition for its successful investments in online travel companies and later achieved a major venture capital success with its early investment in Snowflake. Over time, it has evolved into a prominent technology-focused crossover firm, managing both public and private market investments.

### Notable positions / campaigns
- Snowflake (2015): Led Series C investment in 2015; stake was worth $4.4 billion at IPO.
- Meta Platforms (2022): Published an open letter, Time to Get Fit, urging the company to reduce headcount and limit metaverse spending.
- United Continental Holdings (2016): Pressured the company to change its board of directors due to poor performance.
- Grab (2021): SPAC merger to take the company public.
