How to connect with recruiters (in India) who are hiring a lot of candidates

I am building a saas startup which can help speed up the recruitment process and help recruiters. But i need to validate it before jumping in to build it. Is there a suggestion how can i reach to them. Also reaching to recruiters on Linkedin seems hard. I have DMed many people but they don't seem to reply. If you are a recruiter in India or know someone who can help me out do let me know. It would be really helpful.
