Depending on what your startup is offering, you could create an online course and put it up for free on a website like Udemy.com. There you can build trust with people who will want to look into what you do professionally. I am a Photographer and Web Designer so I created a free intro course on DSLR Photography and another course on Starting a Facebook Page for your business. Both courses have over 10,000 students and it continues to grow. Once you build up enough of an audience, you can start telling them about other opportunities such as what your start up offers.

If you would like, I can send you my VIP link on here and we can spend 10 minutes chatting about it.
