DeepMark (YC F26)

Overview

DeepMark is a YC F26 startup. It puts a silent ID inside an AI voice, so a bank or call center can check if the voice is real.


It still works after the call goes through a phone line. This is a concept project.


DeepMark did not hire me. I picked a product I liked and redesigned its landing page to show how I work.


I did the research, the new page order, the copy, and the design.

Challenge

DeepMark has a great product. But the page made it hard to get.


YC was named twice, which can sound like bragging. The headline ran on one long line. The subhead was too hard to read, and its text was not balanced. The proof sat below the fold. The page looked like just another startup.


The visual idea was good, so I kept it. I did not change the brand much.


The goal: a founder should understand the product's job in one read. Then they can share the page with someone who isn't technical.

Outcome

First I learned what the product does and looked at similar products. Then I fixed the page order and wrote the copy.


The problem now comes right after the hero, and the testimonials moved up. Features went from 6 to 4, because I cut the ones that did not help a founder decide.


The hero uses YC once, keeps the headline on 2 lines, and has a simple, balanced subhead. The copy is short and easy to read. The design is clean, with a plain font, human faces for trust, and simple illustrations.


Note: This is a concept. There are no client results to share.
