Nathan Rose

Nathan Rose

The last wave of Power Platform was about building apps. The next one is about building agents and that's where I now spend my time.

I'm a Power Platform Solution Architect and Microsoft MVP in Auckland, working AI-first: designing agentic solutions that actually do the work, not just chat about it. That means Copilot Studio agents wired into real business processes, Model Context Protocol (MCP) on Dataverse to give those agents grounded, governed access to enterprise data, and M365 Copilot extended so it works the way an organisation actually operates.

What I bring: • Agentic solution design Copilot Studio, autonomous and triggered agents, and the orchestration patterns that make them reliable in production • MCP + Dataverse connecting agents to trusted enterprise data with the right grounding and governance, not bolt-on prompts • M365 Copilot extensibility agents, plugins and connectors that extend Copilot into real workflows • The architecture underneath Dynamics 365 CE, Power Apps and Power Automate, so the AI layer sits on solutions that hold up • Recognised at the edge of this work

Microsoft MVP and part of the team behind the attempted Guinness World Record at the Microsoft Agent Hack

I think and build in the open sharing the experiments, the dead ends and the "hang on, what if I tried it this way?" moments, because this space is moving too fast to learn any other way.

📌 Open to select engagements in agentic AI on the Microsoft stack Copilot Studio, MCP/Dataverse, M365 Copilot. If you're trying to move from Copilot demos to agents that deliver, let's talk DM me.

Daniel Laskewitz

Daniel Laskewitz is a Principal Cloud Advocate at Microsoft. Half of his week goes into Copilot Studio, Copilot Cowork, Scout, GitHub Copilot and Microsoft 365 Copilot, usually with something unfinished open on screen. The other half he spends with the people building the same things, in sessions and workshops and in the community, and what they tell him goes back to the product teams.

On stage he talks about getting an agent past the demo. Wiring it to real systems with MCP, working out when a plain connector is the better answer, and the part nobody puts in a keynote: making the thing safe to hand to somebody else. He has been speaking since 2015, often with a co-speaker.

Please note that Sessionize is not responsible for the accuracy or validity of the data provided by speakers.

Most Active Speakers 2025

Every year, we put together a list of the most active speakers. This list features the top 3% of speakers who have participated in events using Sessionize during the 2025.

The 3% is calculated from the pool of all speakers that have at least one accepted session in year 2025. We don't include inactive speakers or speakers that had no accepted sessions during the year. There are around 39,000 unique accepted speakers this year, the 3% is 1163. Not all of them have their speaker profiles set as public, and we respect that, so the list doesn't show all of them.

The calculation is based on the number of accepted events, that's the main criteria, but to get more refined results we also look at things like multiple sessions per event, sharing a session with a co-speaker and how big the event is. Number of submissions and declined sessions don't affect the list.

Please note that the count of events and sessions in this list does not represent the number of events and sessions from the year 2025. Instead, it shows the number of events and sessions featured on the speaker's public speaker profile; these numbers have nothing to do with the award itself.
