I built https://startthelanding.com mostly for myself as I have needed it a lot over the past few years and always ended up building quick one offs. I'm now working on marketing it through a few different channels while at the same time starting work on my main project that I needed the landing pages for which is a fashion for tech/finance people site. I'm going to be doing a big social campaign for that one soon involving myself so I'm pretty excited but also quite scared since I'm not really the post myself on socials type.
