Frequently Asked Questions
What tools does a SaaS startup need?
At minimum: hosting, CRM, email marketing, support, project management, and accounting. Add SEO, landing pages, and payroll as you grow. Start with free tiers and upgrade when each tool's free limits constrain growth.
How much does a SaaS startup tech stack cost?
$0-200/month using free tiers pre-revenue. $500-2,000/month at growth stage. The free stack above covers every function at zero cost. Upgrade individually as revenue justifies each tool.
Should I use all-in-one tools or best-of-breed?
Start all-in-one (HubSpot for CRM + email, Notion for docs + projects). Switch to best-of-breed when a specific function becomes critical enough to justify a dedicated tool. The integration overhead of 10 separate tools isn't worth it at 5 employees.
