AI in Business: the agent platforms just became a category  May 13th 2026

Watch & Listen First

• Stripe Sessions 2026 Keynote — Collison and Gaybrick unveil 288 launches: Agentic Commerce Suite, Link for agents, stablecoin streaming payments. The clearest read on how the payments rail is being rebuilt for non-human buyers.
• How I AI — Sendbird's elite AI-adoption playbook (May 11) — John Kim on the internal marketplace, skills library and token leaderboard that pushed company-wide usage from novelty to "marketing built a Stripe-integrated swag store in days."
• No Priors — Baseten's Tuhin Srivastava on AI inference (May 1) — Why inference economics, not model quality, now decide which enterprise vendors keep margins.

Key Takeaways

• Agent platforms are the new enterprise category. Sierra, Decagon, Vapi, Writer — buyers are signing seven-figure ACVs on agents that touch revenue, not copilots that touch employees.
• The cost shock has started. Anthropic's April 15 shift to usage-based pricing can double or triple bills for heavy Claude users; 81% of leaders now flag single-vendor dependency as a top risk.
• Copilot and agent are different products with different buyers. 20M Copilot seats prove productivity scaled. Sierra's growth proves agents are a separate buy — often CX or COO, not IT.
• M&A is how incumbents catch up. Roche paid $750M + $300M in milestones for PathAI rather than build. CB Insights logged 266 AI M&A deals in Q1, up 90% YoY.
• Deployment is still the constraint. MIT NANDA pegs 95% of GenAI pilots at zero ROI; the 5% that work share one trait — agents wired into proprietary data, not chatbots on top.

The Big Story

Sierra raises $950M at $15B+ as enterprise agents become a category · May 4 · TechCrunch
→ Bret Taylor's three-year-old company crossed $150M ARR in eight quarters and counts one in three of the world's largest banks plus 40% of the Fortune 50. Tiger and GV are pricing Sierra as the AWS for customer-facing agents; Ghostwriter (the agent that builds agents) reframes it as a platform, not a CX tool. If your SaaS product still needs a human to click a button, your buyer just got a cheaper alternative.
