Prefect

The Model Context Protocol, or MCP, gives developers a common way to expose tools, data, and capabilities to large language models, and it has quickly become an important standard in agentic AI. FastMCP is an open source project stewarded by the team at Prefect, which is an orchestration platform for AI and data workflows. The FastMCP project builds on MCP to provide high-level, ergonomic abstractions for Python developers to rapidly build and deploy MCP servers and applications. Jeremiah Lowin is the founder and CEO of Prefect, and Adam Azzam is the VP of Product at the company. In this episode, Jeremiah and Adam join Gregor Vand to discuss the origin story of FastMCP, the three pillars of the framework, the architectural decisions behind FastMCP 3.0, and much more. Gregor Vand is a security-focused technologist, having previously been a CTO across cybersecurity, cyber insurance and general software engineering companies. He is based in Singapore and can be found via his profile at vand.hk or on LinkedIn. Please click here to see the transcript of this episode.

Workflow orchestration has always been a pain for data scientists, but this is exacerbated in these AI hype days by agentic workflows executing arbitrary (not pre-defined) workflows with a variety of failure modes. Adam from Prefect joins us to talk through their open source Python library for orchestration and visibility into python-based pipelines. Along the way, he introduces us to things like Marvin, their AI engineering framework, and ControlFlow, their agent workflow system.

My guest this week is Jeremiah Lowin. Jeremiah has been on the podcast a number of times over the years. He’s one of my oldest friends who has been a sounding board for me throughout my career. Today he is the founder and CEO of Prefect, which helps companies automate and orchestrate their dataflows. In full disclosure, Positive Sum is an investor in Prefect. We didn’t plan this conversation, but when OpenAI released ChatGPT, I called Jeremiah for a primer on what’s happening under the hood and how best to contextualize this product amidst the growing AI movement. We have these conversations often, but this time I decided to record it so we can all learn from someone I consider to be a leading mind in the fields of data science and machine learning. We start off in the weeds and zoom out as the discussion unfolds.

My guests this week are Jeremiah Lowin and Chetan Puttagunta. Jeremiah is the founder of Prefect.io, an open-source software company where my family and I are investors, and Chetan is a partner at Benchmark Capital. Both are past guests and good friends. I asked them on to help the audience understand the open source software business model. I’ve been fascinated with this model in which companies give a huge chunk of their work and value away for free to a community of developers, and then make money by building additional tools, functionality, and services on top of their free and open platform. While this may strike you as a wonky discussion on a niche software topic, I think it is valuable for everyone because the ideas can be applied to more than just code. I view much of my own activity as open-sourcing investment research and knowledge. It is also important because much of the world’s technology is built on top of open source projects. I hope you learn something new about this emerging category.

Summary Building a data platform that works equally well for data engineering and data science is a task that requires familiarity with the needs of both roles. Data engineering platforms have a strong focus on stateful execution and tasks that are strictly ordered based on dependency graphs. Data science platforms provide an environment that is conducive to rapid experimentation and iteration, with data flowing directly between stages. Jeremiah Lowin has gained experience in both styles of working, leading him to be frustrated with all of the available tools. In this episode he explains his motivation for creating a new workflow engine that marries the needs of data engineers and data scientists, how it helps to smooth the handoffs between teams working on data projects, and how the design lets you focus on what you care about while it handles the failure cases for you. It is exciting to see a new generation of workflow engine that is learning from the benefits and failures of previous tools for processing your data pipelines.

Can you start by explaining what Prefect is and your motivation for creating it? What are the axes along which a workflow engine can differentiate itself, and which of those have you focused on for Prefect? In some of your blog posts and your PyData presentation you discuss the concept of negative vs. positive engineering. Can you briefly outline what you mean by that and the ways that Prefect handles the negative cases for you? How is Prefect itself implemented and what tools or systems have you relied on most heavily for inspiration? How do you manage passing data between stages in a pipeline when they are running across distributed nodes? What was your decision making process when deciding to use Dask as your supported execution engine? For tasks that require specific resources or dependencies how do you approach the idea of task affinity? Does Prefect support managing tasks that bridge network boundaries? What are some of the features or capabilities of Prefect that are misunderstood or overlooked by users which you think should be exercised more often? What are the limitations of the open source core as compared to the cloud offering that you are building? What were your assumptions going into this project and how have they been challenged or updated as you dug deeper into the problem domain and received feedback from users? What are some of the most interesting/innovative/unexpected ways that you have seen Prefect used? When is Prefect the wrong choice? In your experience working on Airflow and Prefect, what are some of the common challenges and anti-patterns that arise in data engineering projects? What are some best practices and industry trends that you are most excited by? What do you have planned for the future of the Prefect project and company?

My guest this week is one of my best and oldest friends, Jeremiah Lowin. Jeremiah has had a fascinating career, starting with advanced work in statistics before moving into the risk management field in the hedge fund world. Through his career he has studied data, risk, statistics, and machine learning—the last of which is the topic of our conversation today.  He has now left the world of finance to found a company called Prefect, which is a framework for building data infrastructure. Prefect was inspired by observing frictions between data scientists and data engineers, and solves these problems with a functional API for defining and executing data workflows. These problems, while wonky, are ones I can relate to working in quantitative investing—and others that suffer from them out there will be nodding their heads. In full and fair disclosure, both me and my family are investors in Jeremiah’s business. You won’t have to worry about that potential conflict of interest in today’s conversation, though, because our focus is on the deployment of machine learning technologies in the realm of investing. What I love about talking to Jeremiah is that he is an optimist and a skeptic. He loves working with new statistical learning technologies, but often thinks they are overhyped or entirely unsuited to the tasks they are being used for. We get into some deep detail on how tests are set up, the importance of data, and how the minimization of error is a guiding light in machine learning and perhaps all of human learning, too.

Jeremiah Lowin is probably the smartest guy I know, and that is saying something. He is an expert in the fields of statistics, artificial intelligence, and risk management—among many other things.  He is currently the Director of Risk Management for a private investment firm in the New York area, but has spent years working with machine learning and AI.  This conversation is broken up into two parts.  In the first part, we explore artificial intelligence, machine learning, and models.  Then we shift to what risk means in a portfolio and how it can be managed or at least redistributed (which starts around 40 minutes into the conversation).  Please enjoy!   For comprehensive show notes on this episode go to investorfieldguide.com/lowin/ For more episodes go to InvestorFieldGuide.com/podcast.  Sign up for the book club, where you’ll get a full investor curriculum and then 3-4 suggestions every month at InvestorFieldGuide.com/bookclub Follow Patrick on twitter at @patrick_oshag
