Someone asked why I like Boom so much. Partly because they're building supersonic jets! Partly because they're doing it so well. And partly because we...
Paul Graham explains his strong support for Boom, citing three reasons: the company is building supersonic jets, executing exceptionally well, and has persevered through many difficult years together with him.
Background
- **Paul Graham** is a well-known programmer, venture capitalist, and co-founder of startup accelerator Y Combinator (YC). His opinions carry weight in Silicon Valley.
- **Boom (Boom Supersonic)** is a Colorado-based aerospace startup trying to build a new generation of supersonic passenger jets (faster than the speed of sound) — the first since the Concorde was retired in 2003.
- Graham's tweet is notable because it references the long, difficult struggle to get the company off the ground: Boom was founded in 2014, and for many years supersonic aviation was seen as a dead technology. Investors were skeptical, and the engineering challenges (fuel efficiency, noise regulations, materials) were extreme.
- The "we've been through so much together" line signals that Graham invested early or advised the company, and is now celebrating its eventual success — the tweet is a reflection on startup grit, not just a product announcement.
