Agentic coding tools (Claude Code, Cursor, Codex), AI APIs, vector databases (Pinecone, Weaviate, pgvector), prototyping platforms (v0, Lovable, Replit), and automation layers (Zapier, n8n) are how you get from idea to working software in days. Also, keep an eye on the sender: we only use official @redventures.com email addresses at the portfolio level or business specific email addresses (e.g., @thepointsguy.com), not ones like "redventurescareer.com."
