How to Build Your AI Stack
Don't try to use all 30 tools. Build a focused stack based on your needs:
- Solo entrepreneur: ChatGPT Plus + Cursor + n8n self-hosted + ElevenLabs = ~€45/month
- Content creator: Claude Pro + Midjourney + Runway + Suno + Notion AI = ~€110/month
- AI automation freelancer: n8n self-hosted + OpenAI API + Vapi + Perplexity = ~€50/month
- Sales team: HubSpot + Clay + Copy.ai + Otter + n8n = ~€250/month/person
Our recommendation: Start with ChatGPT or Claude (free tier), Cursor (free tier), and n8n self-hosted. These three tools alone can replace an entire team for many tasks. Add tools only when you have a specific gap they fill.
