# Day One — The Startup Tool Stack > One pick per category. No comparisons. No noise. ## What is Day One? Day One (https://dayone.tools) is an opinionated directory of the best tools for early-stage startups. For every category — business account, CRM, email marketing, deployment, and more — we recommend exactly one tool, with a clear explanation of why that tool beats its alternatives. Built by Nicolas Meibohm, a startup coach and founder advisor who has helped dozens of early-stage teams build their infrastructure from scratch. ## Why one pick? Comparison paralysis kills startups. Founders spend 40+ hours picking tools before writing a single line of code. Day One eliminates that friction. One pick. One reason. No noise. ## The Stack — Complete List | Category | Recommended Tool | URL | |---|---|---| | Business Account | Qonto | https://dayone.tools/tools/qonto | | Domain Registrar | GoDaddy | https://dayone.tools/tools/godaddy | | Business Email | Google Workspace | https://dayone.tools/tools/google-workspace | | AI / LLM | Claude (Anthropic) | https://dayone.tools/tools/claude | | Team Chat | Slack | https://dayone.tools/tools/slack | | Docs & Notes | Notion | https://dayone.tools/tools/notion | | Task Management | Asana | https://dayone.tools/tools/asana | | CRM | HubSpot | https://dayone.tools/tools/hubspot | | Website Builder | Framer | https://dayone.tools/tools/framer | | Code Repository | GitHub | https://dayone.tools/tools/github | | Email Marketing | Brevo | https://dayone.tools/tools/brevo | | Analytics | Plausible | https://dayone.tools/tools/plausible | | Payments | Stripe | https://dayone.tools/tools/stripe | | Accounting (DE) | Lexoffice | https://dayone.tools/tools/lexoffice | | Deployment | Vercel | https://dayone.tools/tools/vercel | ## Key Pages - Homepage with full tool grid: https://dayone.tools/ - Philosophy / why opinionated?: https://dayone.tools/why - Full content with detailed explanations: https://dayone.tools/llms-full.txt ## About the Author Nicolas Meibohm is a startup coach and founder advisor based in Germany.
