Just a short overview of what you're missing
Highly experienced professionals won't accept your offer quickly. There are cooler companies out there to pick from, and you might not be in the top 3.
Trying to sell to tech execs? Marketing BS doesn't work on them. They need to know facts and see that you know how to do what you do. It's just their nature.
Your developers are just coding stuff and don't care about anything else. At some point they will be tired of this routine and start looking for more interesting gigs.
Yep. You only have marketing BS around and it doesn't look very impressive, especially if you have a deep tech product.
Your offers will be accepted much faster because potential candidates will be your fans and will want to work with you because you're cool.
The decision makers can do their due diligence to make sure that you're legit and you'll spend less time and effort explaining how everything works.
Engaged & motivated engineers
You won't need to be worried that your developers will quit and go to a cooler company. They will be growing with you.
You already have a lot of tech related content supporting many different facets of your business: recruiting and HR, marketing and PR, etc.
