Hey great question, getting clientele online can be difficult without the right strategies..

Great you have your ideal client avatar down that's important. Normally with startups they do not have a lot of capital to give while building..

You definitely want to start step by step..

WHERE ARE THEY HANGING OUT AT?
There's start up events that are always going on to attend.. Especially in Los Angeles.. Not sure where you are in the world but attending these events are greater in person than they are online..

You can run into investors as well..

If you lookup "Tech Start Up Events in Los Angeles" on google..
They have an infinite amount of events happening throughout the month.. Its getting close to summer so there's going to be a lot more events..

Also Facebook groups I would go for the Influencer groups like grant cardone and tony robbins groups.. Some of the facebook groups are just garbage..

But I hope I gave some good ideas..
