Find clients for a tech recruiter

I have built a platform for JavaScript developers. Now
that I have many devs that subscribed to the service,
need someone able to find customers. Customers of
this platform will be recruiting staff of companies and
startups (typically, the CTO).
So if you are able to contact CTO that recruits, and
explain why I can help them better than other
recruiters, then this job is for you.
I will show you the platform and added value first,
before to start the job
Good luck!
