Typeback and the Anthropic IPO
This week's guest was Patryk Reba (Founder, Typeback), who built an AI keyboard for iPhone that reads the chat on your screen and writes the reply in your own voice — and he ran it live on a WhatsApp conversation in front of the room. Then Nick brought the biggest news in AI this month: Anthropic is going public, in what will probably be the largest IPO in world history. Its revenue went from $41 million to $16.2 billion in under three years, a climb that took Microsoft and Amazon about twenty years.
- Typeback sits where your keyboard already is, so you stop screenshotting chats into ChatGPT and pasting the answer back; it learns your style from the messages you send.
- Q&A: Patryk ran hundreds of comparisons across Claude, DeepSeek, Kimi and others before choosing Claude for how it reads context, and Typeback picks up a chat you come back to days later, in any language.
- Typeback is free while it is in beta.
- Anthropic's listing is likely to be the largest IPO in history: $16 billion of revenue in the first half of the year, up from $41 million to $16.2 billion in under three years, a climb Microsoft and Amazon each took about twenty years to make to $10 billion.
- Gross margin is now 72%, for a company already at that scale.
