What AI stack do most founders use?
Most founders who get real leverage use 1–2 tools: usually Claude or ChatGPT for writing and reasoning, and optionally Cursor for coding or Perplexity for research. Paying for more than two subscriptions rarely pays off.
Is Claude or ChatGPT better for founders?
Claude Pro is better for document-heavy work — strategy docs, fundraising materials, and long analysis. ChatGPT Plus is better for breadth — marketing, ideation, and quick generation tasks. The choice depends on your dominant daily workflow.
What should founders not pay for yet?
Avoid subscribing to: Notion AI as a standalone expense (only worth it if Notion is your core workspace), Grammarly Pro (Claude or ChatGPT handles editing better), and multiple frontier AI subscriptions before validating which one you actually use daily.
