David Pawlan says personal AI agents will win by proactively saving money, as Assistant Bench tracks 122 products and costs reach $20 per user daily.
On the a16z show, General Partner Anish Acharya and Assistant Bench creator David Pawlan survey the fast-growing personal-agent market, from Poke and OpenClaw to Instinct and Muse. Pawlan says Assistant Bench compares assistants on real tasks across 16 dimensions; its site drew over 100,000 visitors, while he has cataloged 122 agents. They argue that everyday users care less about being 10% more efficient than about invisible help that saves money: agents can claim HSA reimbursements, recover airline credits, and even cut a household’s water bill by 50%. ChatGPT voice sorted Pawlan’s email and sent calendar invites during a 30-minute bike ride. The conversation weighs privacy and trust, agent participation in group chats, Meta’s Muse charm as potential real-world data collection, and Amazon blocking Muse while Shopify embraces it. Pawlan sees proactivity as a moat, but warns that one unauthorized action can destroy trust. They close on agent-to-agent commerce and the economics: ambitious agents may cost $20 per user per day, challenging startups to deliver value worth paying for.
