Best AI tools for building at Series A startups.
Building is where most founder-time goes. The tools below are picked for that work specifically: AI-first IDEs (Cursor, Windsurf, Zed), autonomous coding agents (Cline, Aider, Devin), no-code prototyping (Bolt, Replit, Lovable, v0), and the agent infrastructure layer underneath (Pinecone, Together, Helicone). Picks favour composability and self-serve pricing. At this layer your tools should grow with the product, not force a migration. Series A is the scaling phase. The tools for building below sit in the mid-market sweet spot: substantive AI features, public APIs and MCP servers for agent-readiness, and clear price tiers that don't punish growth.
