Lionel Sim helps enterprises in Singapore and Asia Pacific build agentic AI systems for sales, marketing and go-to-market.
His craft is go-to-market and B2B sales, built inside companies where execution was the culture: Apple, then Tencent helping WeChat expand internationally, then four years at TikTok building market expansion teams across Asia. He opened markets, built partner ecosystems, and learned firsthand how enterprise buyers in Singapore, Greater China and Southeast Asia make decisions. In those environments, AI and automation were never the future. They were how Monday morning worked.
AI is now shifting from answering questions to doing work. Lionel calls it agentic selling: AI agents that prospect, qualify, follow up, run campaigns and operate revenue workflows end to end. The winners of the next few years will not be the companies with the most AI pilots. They will be the ones that rebuild their go-to-market around AI agents.
Lionel works with enterprises across Singapore and APAC to design agentic selling, AI marketing and GTM systems that show up in the numbers, built for how the region actually buys, sells and partners.
He is the author of three books on AI sales and marketing: The AI Selling Revolution, The AI Marketing Revolution and The AI Agent Revolution. He writes Agentic AI Revenue, a weekly newsletter on agentic sales and GTM read by more than 6,000 operators and executives, and leads OpenClaw and Hermes AI Singapore, an AI agent builder community of more than 8,000 members.
