Nice work on the tech. The presentation however is a bit dusty and doesn't do a good job of presenting the awesome service you've built here in a way that converts traffic into customers. I've designed a bunch of products tailored specifically to the same kind of engineer. Here are some things I've learned that apply specifically here. Perhaps it can point you in the right direction and help you present your service better:

- you can probably reduce the copy by 70%. The tech is clear, and it should be faster to go from 'Oh wow this is cool' to 'ok I know how it works'. Don't underestimate the intellectual level of your target audience here.

- You also don't have to say everything on the lanidngpage here's how I would restructure it:

Simple OTP The world's simplest way to add One Time Passwords Magic sign-in link authentications to your website.

[Then show the code that the engineer needs to implement] [Next to it you show that gif of how it works]

Underneath you have the signup form.

that's it.

You an leave the details inside a Docs page, or in the follow up email.

The goal here is to explain what you do in 10 seconds and capture that lead.

Great job on the product! Hope this helps you evolve it further.
