Hi,

If you are asking how to do it technically then you can use any of the web page development services (e.g. Wix) and add a form that is linked to a list service (e.g. MailChimp).

If you are asking how to attract potential customers and persuade them to submit the form then there are a number of things to try.

To attract them, you can use paid ads or organic (e.g. Facebook/YouTube/Instagram text/video posts given that this is B2C). The ads/posts must address users' pain/need/desire and show that you will solve this. Ideally, offer some value (useful insight etc.) in the ad/post to show you really can solve it.

To persuade them to sign up, again, the page should remind them of the pain/need/desire and how you can solve and ideally offer immediate value (e.g. white paper) when they register (as well as future promise of an app they might have to pay for).

Also, if you can think of a way of giving additional value for referrals that will help.

Kind regards

Stuart

Here some ideas:
#1 Try to create a referral program where someone signup for the waitlist will rank higher if they invite someone else. Or try to give something in exchange. x% discount in the first order.
#2 Spread in all social media channels and explain about how can be useful for users. Don't stop making videos everywhere every day.
#3 Add the landing page in all the beta directories possibles.
#4 Reach network. Send messages and emails to everyone to join the waitlist.
