Key positions and views

AI tools have democratized software development, enabling non-technical individuals to build valuable products without writing traditional code, a shift he marks as occurring around Thanksgiving 2023.

The primary value of contributing to open-source projects is not the code itself, but the strategic networking and relationship-building it facilitates with top talent in the field.

It is a valid and powerful technique to use HAR sniffing to discover and build upon the 'secret' or undocumented APIs of services that do not offer official ones.

AI agents are inherently 'lazy' and require a sophisticated scaffolding of custom tools—like CLIs, agent skills, and local databases—to perform complex tasks reliably and efficiently.

A product's value can be proven even with a single user if it effectively solves a personal problem, as he states is the case with his Agent Cookie tool.

Timeline

High School

Claims his last experience with coding was with HTML and AppleScript.

2007

Began his first job in the tech industry at Digg.

Thanksgiving 2023

Identifies this as a critical turning point when AI development tools from Anthropic and OpenAI became powerful enough to build valuable products, shifting them from 'toys' to 'real'.

Post-Thanksgiving 2023

Developed and launched several products based on new AI capabilities, including The Printing Press and Agent Cookie.

Recent

The Printing Press project grew significantly through community involvement, expanding from approximately 40 CLIs at launch to over 200.

Recent

Received full-time job offers from other founders as a direct result of his open-source work and networking.

Podcast consensus on Horn

Points of consensus

▶Matt Van Horn is a self-described non-technical founder who does not write or read code, yet successfully builds software products like 'The Printing Press' and 'Agent Cookie' by leveraging AI-driven tools like Compound Engineering.Jun 2026

▶A core technique in his work is creating Command-Line Interfaces (CLIs) for services that lack official APIs, which he achieves by using HAR sniffing to discover and utilize undocumented or 'secret' APIs for companies like OpenArt, Suno, and Google Flights.Jun 2026

▶He strategically uses open-source contributions as a primary method for networking with influential 'agentic builders', which has directly resulted in full-time job offers from other founders.Jun 2026

▶He believes AI agents have an inherent 'propensity to be lazy' and require custom-built tools, such as CLIs and local SQLite databases, to improve their performance and efficiency.Jun 2026

Points of debate

▶Van Horn claims to be entirely non-technical and unable to read or write code since high school, yet he also claims to have successfully contributed a major feature to the Python programming language, creating a contradiction regarding his technical capabilities.Jun 2026

▶His approach to the open-source community is mixed; while he has successfully contributed to major projects like Python, he has also been banned from contributing to the Rust programming language, suggesting his methods or contributions are not universally accepted.Jun 2026

▶His primary product, The Printing Press, relies on reverse-engineering and using private APIs from companies without their explicit permission, a practice that could be considered a violation of terms of service and carries significant platform risk.Jun 2026

▶He develops innovative products like an AI startup simulation game but expresses fear of a negative reception, indicating a potential conflict between his ability to build and his confidence in launching his creations publicly.Jun 2026

Key themes

▶The Non-Technical Agentic EngineerJun 2026

Van Horn embodies a new archetype of software creator who builds sophisticated tools without traditional coding skills. He leverages high-level AI development platforms like Compound Engineering to translate product vision directly into functional software, asserting that his last coding experience was HTML in high school.

This trend suggests a significant lowering of the barrier to entry for software creation, where strategic thinking and prompt engineering may become as valuable as traditional programming expertise, potentially disrupting how tech teams are structured and hired.

▶Leveraging Undocumented APIsJun 2026

A core strategy for Van Horn's tool, The Printing Press, is the use of HAR (HTTP Archive) sniffing to discover and build upon 'secret' APIs for services that lack official public ones, such as Google Flights, Midjourney, and Suno. This allows him to create CLIs and agent skills that provide programmatic access where none formally exists.

This approach highlights a market of unmet developer needs but is inherently fragile; it relies on APIs that can be changed or deprecated without warning, as seen with the Domino's Pizza API, posing a significant platform risk for any business built on this foundation.

▶Open-Source as a Networking StrategyJun 2026

Van Horn explicitly states that the primary benefit of his extensive open-source work is not the code itself, but the relationships and network it builds. By contributing to the community, he connects with the 'most interesting agentic builders' and has received tangible career opportunities, including full-time job offers.

This reframes open-source participation from a purely technical or altruistic endeavor into a powerful business development and personal branding tool, suggesting that in the AI space, demonstrating capability through public work can be more effective than traditional resumes or networking.

▶Tooling for AI Agent EfficiencyJun 2026

Van Horn believes AI agents are inherently 'lazy' and seek to complete tasks with minimal effort (and token usage). To counteract this, he focuses on building a robust 'scaffolding' of tools, such as CLIs, agent skills, and local SQLite databases for fast queries, inspired by the work of Peter Steinberger.

This indicates that the advancement of AI applications is not solely dependent on model improvements, but equally on the ecosystem of specialized tools that enable agents to interact with data and services reliably and efficiently, creating a market for 'agent-enablement' software.

“The third thing that it does is it goes and it does a HAR sniff to look for secret APIs. So I'll give an example. So the Google Flights and Kayak Direct, they do not have an official API. But if you do a HAR sniff and click around, you can find all the secret APIs.”
