Do super personalized outreaching

I've had a similar problem in my personal development journey.

I haven't solved it, but my experience has lead me to believe that building in public and blogging/vlogging your journey (why you started and what you learned) is promising. That type of content drives brand and product hype via views/engagement, helps you filter ideas (if your vlog is getting no traction, maybe not a great product?) and avoids promotional post rules in a lot of communities.

My new years resolution is to dial in my content driven development pipeline.

I’m a indie developer and do marketing for my products. Build in public is a good way because building becomes the content which is the hard part. If you have an idea of your ICP, then cold outreach on LinkedIn specially if you are building and have people following you and commenting on your post. Don’t rely only in just the posts. I recently deleted every post on my linkedin with the goal of starting building in public and following this method which is the answer to your question. I belong to a paid community of very successful bootstrapped business developers and this is what the top members do, granted they are very successful and paid people to write their content which can be time consuming.
