I have a friend in finance that uses LLM powered products for financial analysis, he works in a big bank. Just now anthropic released a product to compete in this space.
Another friend in real estate uses LLM powered lead qualifications products, he runs marketing campaigns and the AI handles the initial interaction via email or phone and then ranks the lead in their crm.
I have a few friends that run small businesses and use LLM powered assistants to manage all their email comms and agendas.
I've also talked with startups in legal and marketing doing very well.
Coding is the theme that's talked about the most in HN but there are a ton of startups and big companies creating value with LLMs
