Foundational: one AI assistant for everything

Before adding specialised tools, a team of 1–10 should start with one powerful general AI. ChatGPT Plus ($20/mo) or Claude Pro ($20/mo) handles writing, research, coding help, competitor analysis, pitch decks, investor memos, and customer emails. Choose one and get good at it before expanding the stack.

Product and engineering

Cursor — AI code editor for speed

Cursor gives developers AI-assisted coding that actually works on real codebases. It understands your entire repo, not just the current file. For early-stage teams shipping fast, it meaningfully increases developer velocity.

Pricing: Free (hobby) / $20 Pro

Lovable / Bolt.new — build MVPs without a full dev team

Lovable and Bolt.new let non-developers build functional web apps from natural language prompts. For founders who want to test an idea before hiring an engineer, these tools can produce a working prototype in hours.

Pricing: Freemium — both have generous trial tiers

Marketing and content

ChatGPT / Claude — copy, emails, ads, social

At the early stage, general AI handles most marketing content needs: landing page copy, email sequences, LinkedIn posts, ad variants, press releases, and blog posts. No specialist tools needed until you are producing at significant volume.

Canva — design for non-designers

Canva's AI features (Magic Design, Magic Write, background removal) handle social media graphics, pitch deck slides, and simple marketing collateral without a designer.

Pricing: Free / $15 Pro

Customer support

Intercom with Fin AI — resolve support queries automatically

Intercom's Fin AI agent resolves the majority of repetitive support queries without human involvement. For startups with a growing user base and limited support headcount, this is one of the highest-ROI tools on this list.

Pricing: From $39/mo + $0.99/resolution for Fin

Operations and productivity

Notion AI — company knowledge base with AI

Notion AI lets your whole team ask questions of your internal docs, meeting notes, and wikis. As a startup scales, institutional knowledge becomes fragmented — Notion AI makes it searchable and queryable.

Pricing: $10/member/mo (AI add-on on existing Notion plans)

Zapier — automate the repetitive stuff

Zapier connects your tools and automates repetitive workflows — routing leads from forms to CRM, sending Slack notifications on Stripe events, syncing customer data across platforms. The free tier handles simple 2-step automations.

Pricing: Free / $20 Starter
