AgentExchange: Salesforce's Bet on the Agent Economy

Tue, 05 May 2026 00:00:00 +0000

Salesforce’s AgentExchange is more than a marketplace — it’s an architectural statement about who will control the agent economy. For PMs building on or competing with the Salesforce platform, understanding its mechanics, incentives, and strategic implications is quickly becoming essential.

From Intent to Impact

Tue, 15 Jul 2025 00:00:00 +0000

To Grok or not to Grok

Mon, 14 Jul 2025 00:00:00 +0000

Grok 4, a new LLM, boasts advanced reasoning, real-time search, and tool use, with a dual-model architecture (Standard and Heavy) and strong academic benchmark performance. However, its launch is marred by concerns over ideological bias (referencing its founder’s posts), a major antisemitic content moderation failure, and rapid jailbreak vulnerabilities, raising questions about its safety and neutrality despite ambitious future plans.

PMs versus AI Agents

Sat, 05 Jul 2025 00:00:00 +0000

Generative AI in product teams is limited by data access and isolation. The next wave is AI agents deeply integrated into core systems, acting as proactive, autonomous, goal-oriented, context-aware, and action-oriented digital teammates. This will transform product management by automating mundane tasks, freeing PMs to focus on true strategy, discovery, and leadership, amplifying their impact.

Prompt Engineering: Dead?

Sat, 05 Jul 2025 00:00:00 +0000

Manual prompt engineering is inefficient and dead. The future involves automated prompt optimization using a three-part system: a core LLM application, an LLM-as-a-judge evaluator to measure performance, and an auto-improving agent that researches, generates, and refines prompts. This approach has shown significant performance gains, shifting the focus from manual prompt tweaking to building robust evaluators and agentic systems for continuous, automated LLM improvement

About

Mon, 01 Jan 0001 00:00:00 +0000

Hey, I’m Ros.

I’m a product manager in the Bay Area with over a decade of experience building products at Amazon, Salesforce, and Sephora. My work sits at the intersection of AI, data, and enterprise software — turning early-stage ideas into products used by millions.

This blog is where I think out loud about the things I find most interesting right now: how AI agents are reshaping product work, what it means to build in a world where prototyping is nearly free, and how the enterprise software stack is being rebuilt from scratch around intelligence.
