For a customer outreach as a solo founder: is the lightweight tooling actually enough or are you always hitting walls

When you are at a stage where reaching potential customers is the priority but the big platforms are way more than what's needed right now. Pipeline is maybe 20-30 contacts a week and quality matters more than volume bc every conversation actually counts, there's no volume to hide behind if the outreach isn't landing. Not sure if the right answer is just linkedin plus a spreadsheet plus a lightweight lookup tool or if there's something I'm obviously missing that makes a big difference at this stage.
