The $0/mo Founder Stack
Everything a solo founder needs to run a business without spending a dime. Free tiers only.
Everything a solo founder needs to run a business without spending a dime. Free tiers only. This stack assembles 5 tools that work together for a total of $0/mo. Each pick is the result of weighing dozens of options in its category against the specific constraints of the audience this stack is built for: budget, team size, technical depth, and the workflow that needs to be supported.
Below is the full tool list, with the specific tier to pick, the cost, and our score. After the cards, you'll find a per-tool explanation covering why it earns its slot in this stack and when you should consider swapping it for an alternative. If your situation differs from the audience this stack targets, the swap notes will help you adapt the recommendation to your reality.
Why Each Tool Earns Its Slot
HubSpot CRM for CRM
The best free CRM on the market. Generous free tier, intuitive UI, and a massive ecosystem. The paid tiers get expensive fast, but the free version alone beats most paid competitors. For this stack, the Free tier at $0 is the right starting point because it covers the crm role without paying for features the rest of this stack already handles. Best free tier in the CRM market.
The fit reason: HubSpot CRM scores 8.9/10 in our review and is built for smbs who want a crm they can start using today without paying a dime. If your situation matches that profile, this is the right pick. If it doesn't, see the alternatives in our best crm guide.
Notion for Docs & Project Management
A beautiful, flexible workspace for docs, wikis, and project tracking. Excels as a knowledge base. The project management features work but are a step behind dedicated PM tools. For this stack, the Free tier at $0 is the right starting point because it covers the docs & project management role without paying for features the rest of this stack already handles. Strongest docs and wikis in the category.
The fit reason: Notion scores 7.9/10 in our review and is built for small teams who value documentation as much as task management. If your situation matches that profile, this is the right pick. If it doesn't, see the alternatives in our best project management guide.
MailerLite for Email Marketing
The best value in email marketing. Clean interface, solid deliverability, and a useful free tier with 1,000 subscribers. Does 80% of what ConvertKit does at 60% of the price. For this stack, the Free (1K subs) tier at $0 is the right starting point because it covers the email marketing role without paying for features the rest of this stack already handles. Best value in the category.
The fit reason: MailerLite scores 8.0/10 in our review and is built for bootstrapped founders and small teams who want great email without the premium price. If your situation matches that profile, this is the right pick. If it doesn't, see the alternatives in our best email marketing guide.
Trello for Task Management
The original kanban board. Dead simple, easy to learn, and free for basic use. Outgrown by any team with more than a handful of projects, but still the fastest way to get started. For this stack, the Free tier at $0 is the right starting point because it covers the task management role without paying for features the rest of this stack already handles. Simplest PM tool to learn.
The fit reason: Trello scores 7.0/10 in our review and is built for solopreneurs and tiny teams with simple project needs. If your situation matches that profile, this is the right pick. If it doesn't, see the alternatives in our best project management guide.
Zoho Desk for Customer Support
Affordable help desk from the Zoho ecosystem. Good feature set for the price, but the UI is a step behind Freshdesk. Best value if you are already invested in Zoho's suite. For this stack, the Free (3 agents) tier at $0 is the right starting point because it covers the customer support role without paying for features the rest of this stack already handles. Very affordable.
The fit reason: Zoho Desk scores 7.0/10 in our review and is built for teams using other zoho products who want a unified ecosystem. If your situation matches that profile, this is the right pick. If it doesn't, see the alternatives in our best help desk guide.
How to Use This Stack
Three steps to set up The $0/mo Founder Stack in a single afternoon:
- Sign up in the order listed. The first tool is your foundation. Get it running first, then layer on the others. Don't try to set up everything at once or you'll end up with half-configured tools and no working stack.
- Use the exact plans called out above. Vendor pricing pages push you toward higher tiers. The plans we recommend are the ones that actually fit this stack's audience. Going one tier higher usually wastes 30-40% of the spend on features you won't touch.
- Connect the integrations day one. The value of a stack is in how the tools talk to each other. CRM data should flow into email. Project management should pull from your ticketing tool. Set the integrations up before you load real data, not after.
Total cost at list pricing is $0/mo. Most of these tools discount 15-20% on annual prepay, so the real annual cost is usually 10-15% lower than 12x the monthly number. Ask sales for an annual quote when you sign up.
When to Upgrade Beyond This Stack
This stack is built for a specific stage. You'll outgrow it. The signals that you're ready for the next level usually look like one of these:
- You're hitting feature limits weekly. If you're asking your team "can our tool do this?" more than once a week and the answer is "no," it's time to look at upgraded plans or alternative tools. Our category guides help you find the next step.
- The math no longer works. Per-seat tools get expensive fast. If you doubled in size and your stack cost more than doubled, audit which tools are charging per-seat and consider flat-rate alternatives. Some of our pricing pages calculate the team math directly.
- Workflows are breaking at the seams between tools. When data isn't flowing cleanly between two tools in your stack, the answer is usually a different tool that integrates better, not more middleware. Re-evaluate which tools play well together at your new scale.
When you're ready to scale beyond this stack, browse the related stacks on the stacks index page to find the next tier up. Most teams move through 2-3 stacks as they grow from solo founder to mid-sized company.
