Early-stage startups don't need a $500/month SaaS stack. The nine tools below cover most of what a small team needs — each one free or with a genuinely usable free tier in 2026 — and each removes a specific piece of friction that would otherwise consume founder hours.

1. Notion (free for personal and small teams)

Wiki, task board, doc repo, CRM-lite. The universal value is having one searchable surface instead of four scattered ones.

2. Google Workspace (free on gmail; cheap on custom domain)

Docs, Sheets, Calendar, Drive. The collaborative editing is still best-in-class even after a decade.

3. Slack (free tier)

90-day history on free. Enough for teams under ten. Channel discipline matters more than the plan level.

4. Loom (free: 25 videos, 5 min each)

Replaces many meetings and many long emails. The free tier is generous enough to cover a small team's regular use.

5. Cal.com (open source, self-host free)

Calendly alternative. Host free on your own infrastructure, or use the hosted free tier. Booking links end scheduling emails.

6. Trello or Linear free tier

Task management without Jira's weight. Trello for anything; Linear if you're shipping software.

7. Figma (free for up to 3 files)

Design and prototyping. Even non-designers benefit from drawing flows and mocks before building.

8. Zapier (free tier: 100 tasks/month)

Enough to automate the two or three highest-leverage workflows. Upgrade when you hit the ceiling; most early-stage teams don't for months.

9. HubSpot CRM (free)

Honest CRM capability without a per-seat charge. Good enough for the first 50-100 customers.

The minimum viable stack

Notion + Google Workspace + Slack + Cal.com covers 80 % of a small team's needs for essentially nothing. Add Loom and Zapier when the workflow warrants them. Resist every upgrade for at least six weeks — the fancy features rarely outweigh the cost of switching.
