The questions
What actually is an AI agent, in plain language?
An AI agent is software that uses an AI model as its brain to pursue a goal: it plans the steps, uses tools (your email, browser, spreadsheets, code, APIs), ...
Why would a founder use agents instead of a chatbot or automation?
Chatbots answer questions and classic automation follows fixed if-this-then-that rules; both break the moment a task needs judgment. Agents sit in between: t...
What real tasks are founders delegating to agents today?
Founders are handing agents inbound sales and lead qualification, customer support, competitor and market research, meeting prep and follow-ups, content draf...
How do I build my first agent without being technical?
Start with the assistant you already pay for: Claude and Tasks in Gemini run a plain-English job on a schedule. To connect several apps, use Zapier Agents or...
Which platform or framework should I build my agents on?
Match the tool to who is building. Non-technical founders should start no-code (Zapier Agents, Lindy, n8n) and only graduate when they hit a wall. If you hav...
How much do AI agents cost to run, and how do I keep the bill under control?
Token prices for equivalent quality fall roughly 10x a year, yet agent bills keep rising because agents burn about 50 times the tokens of a chat: every step ...
How do I test an AI agent and know when it's reliable enough to trust?
You test agents with evals: a set of real tasks plus grading logic, run repeatedly because the same input can produce different outputs. Start embarrassingly...
What can go wrong when an agent acts on my behalf, and how do I keep it safe?
The core risk is Simon Willison's lethal trifecta: an agent that reads your private data, sees untrusted content (any email or web page) and can communicate ...
What is MCP, and why does it matter for my agents?
MCP (Model Context Protocol) is an open standard, started by Anthropic in late 2024 and since adopted by OpenAI and Google, that works like a USB-C port for ...
Should I build one agent or a team of agents working together?
Start with one. The famous industry debate (Cognition's "Don't Build Multi-Agents" vs Anthropic's multi-agent research system) actually agrees on the fundame...
Can coding agents like Claude Code actually build my product?
Yes, further than most founders expect: teams like Every ship multiple products with engineers writing almost zero code by hand, and 80-90% of Claude Code it...
Is there a real startup opportunity in building vertical AI agents?
Yes, and it may be the biggest one of this cycle: YC's partners argue vertical AI agents could be 10x bigger than SaaS because they tap labor budgets, not so...
How should I price a product built on AI agents?
Per-seat pricing breaks when your product replaces labor instead of assisting it: agents don't have seats. The market is converging on usage and outcome pric...
Why do most AI agent projects fail, and what do the winners do differently?
MIT's much-cited finding is that 95% of enterprise AI pilots deliver no measurable ROI, and the cause is rarely the model: it's missing context, no workflow ...
How do I give my agent the right context and memory so it stops forgetting?
