Ranked & reviewed
Every dollar matters before product-market fit. These are the tools with genuinely useful free tiers — not crippled demos — that can run a startup's core operations at zero cost.
Our top pick
Free forever plan
HubSpot CRM's free tier is the most generous in its category. No contact limit, full pipeline management, email tracking, and meeting scheduling — all permanently free.
Get CRM free →A fully functional startup can run on: HubSpot CRM free, Mailchimp free (up to 500 contacts), Canva free (design), Notion free (docs and planning), Zapier free (up to 100 automations/month), and Calendly free (scheduling). That is CRM, email, design, productivity, automation, and scheduling at zero cost.
Free tiers become limiting at predictable points: Mailchimp at 500 contacts, Zapier at 100 tasks/month, Calendly when you need multiple event types. Plan your upgrade path before hitting limits — the transition is smoother if it is anticipated.
If there is one tool worth paying for before revenue, it is a landing page builder. Leadpages at $37/month lets you run real conversion experiments and capture payment intent — things that directly generate revenue. Everything else can stay free longer.
Full recommended stack for bootstrapped founders, pre-revenue startups, and budget-conscious entrepreneurs
Based on your input
I am starting a business with almost no budget and need free tools
A practical recommendation for software, tailored to your growth budget, intermediate skill level, and starting stage.
Best first step
Launch a landing page that captures waitlist or demo interest.
Advisor insight
For SaaS, the stack should validate demand before you spend weeks building features nobody asked for.
Landing Page Builder
Best for: Paid ad landing pages with A/B testing
Best when the user plans to run ads and needs focused landing pages, lead capture, and conversion optimization. Built specifically to maximize ad ROI.
Choose this if
Paid traffic or lead generation is the main goal and conversion testing matters.
Pricing note
14-day free trial included
Option #2 · CRM & Sales
Free forever planBest for: Lead tracking and follow-up
Recommended because the real leak in many software businesses is slow follow-up, not lack of traffic. A free CRM fixes that immediately.
Choose this if
Leads, quotes, demos, or follow-up conversations are central to your business.
Tradeoff
Can feel heavy if the business has very few leads or no follow-up process yet.
Alternative
ActiveCampaign
Better if email automation and lead nurturing matter more than CRM depth.
Paid plans from $15/mo per user
Option #3 · Payments
2.9% + 30¢ per transactionBest for: Online payments and billing
The go-to payment infrastructure for web-based businesses. Accepts cards, bank transfers, and 135+ currencies. Easy to embed into any site or tool.
Choose this if
You need to accept payments online and want maximum flexibility over how billing works.
Tradeoff
Requires technical setup — not a full e-commerce platform on its own.
Alternative
Shopify
Better if you need product pages and inventory alongside payments.
No monthly fee — pay as you go
Option #4 · Email Automation
From $15/moBest for: Lead nurturing and advanced automations
Useful if you want automated follow-up after a form submission, quote request, or signup — instead of manually chasing every lead.
Choose this if
Automated follow-up and lead nurturing are important from day one.
Tradeoff
Can be overkill for a tiny list or very early validation stage.
Alternative
Mailchimp
Generous free tier — good starting point before you need automation depth.
14-day free trial available
Option #5 · Landing Page Builder
From $37/moBest for: Simple lead capture pages
Good for opt-in pages, campaign pages, and fast lead generation without building a full website.
Choose this if
You want a simple landing page for lead capture without building a full website.
Tradeoff
Less flexible for full websites or advanced design systems.
Alternative
Unbounce
Better for A/B testing and higher-intent paid ad campaigns.
14-day free trial available

Common ways businesses overcomplicate the first version.
Full product builds before validation
Building all features before talking to users is the most common early-stage mistake in SaaS. Validate first with a landing page.
Enterprise sales tools before a pipeline
Outreach.io and Salesloft are for teams with established pipelines. Start with HubSpot free.
Subscriptions you cannot connect to revenue
Every SaaS subscription is a monthly decision. If you cannot explain exactly how a tool connects to revenue or lead capture, skip it for now.
HubSpot CRM free is the best option. It has no contact limit, includes pipeline management, email tracking, and meeting scheduling. It outperforms most paid CRM alternatives for early-stage startups.
Mailchimp is free for up to 500 contacts and 1,000 sends per month. That is enough to run a launch sequence, welcome series, and regular newsletter without paying anything.
Yes, for the first 6-12 months. HubSpot, Mailchimp, Canva, Notion, Zapier, and Calendly all have free tiers that cover core startup operations. The main limitation is email list size (Mailchimp caps at 500 free contacts).
