5 Free Tools Every Solo Founder Needs Before Spending a Dollar

The fastest way to burn through your startup budget is buying tools before you need them. I started a business with $1,000. Here are the only tools I actually use, and they are all free or nearly free. 1. Google Sheets (Free) Forget Notion databases and fancy project management tools. A spreadsheet tracks your finances, your customers, your metrics, and your to-do list. One tool, zero learning curve. I built my entire financial model in Google Sheets. MRR tracking, burn rate, runway projection, unit economics. Six tabs. No subscriptions. If you want the template instead of building from scratch: Solo Founder Financial Model 2. Gumroad or Lemon Squeezy (Free to Start) Do not build a website with a payment system. Use a platform that handles payments, delivery, and tax compliance out of the box. Gumroad takes 10% per sale. Lemon Squeezy is similar. Both let you start selling in under an hour. You can always move to your own infrastructure after you have revenue. The trap: spending weeks
