Are Vertical AI Agents still worth building?

I recently came across some news:

Claude for Financial Services officially launched in mid-July. It’s designed specifically for the finance industry, integrating data from platforms like PitchBook, Morningstar, Snowflake, S&P Global, and Databricks to support market research, due diligence, and investment decisions. During early testing, Claude Opus 4 hit 83% accuracy on complex Excel tasks.

It really makes me question how much room there is left for AI Agent startups ----LLMs are getting better at handling more and more tasks on their own.

For an AI Agent to have long-term value, it must be able to understand, remember, and adapt to a user's evolving preferences and context ---- something LLMs still struggle with due to their limited memory and continuity.

Also, not many vertical AI Agents seem to be breaking out yet. Off the top of my head, I can only think of Icon, telli, and Exa. Curious to see what other intereating vertical AI Agent products show up on Product Hunt.
