I have seen many developers here on HN who build awesome stuff but then struggle with the marketing.

Momentum is designed for solo developers who don't have the time or skills for promoting their apps and services. It helps you find the most relevant blogs, websites, forums, journalists, social influencers in your target market. It also makes a tailored content marketing plan and helps you optimise your marketing site.

It's basically like Hubspot for solo entrepreneurs.

I'd love for you to check it out and give me your feedback. Thanks!
