Who Is This Course For?

• The Product Builder — You're building a SaaS, an app, or an internal tool and you want a clear, repeatable process for shipping with AI rather than scattered YouTube tips and Discord rabbit holes. You've dabbled with Cursor and ChatGPT but still feel like you're improvising every session. Builder Methods gives you the structured methodology to ship real features confidently.

• The Career Developer — You've been writing code professionally for years, maybe a decade or more, and you see the industry shifting fast toward AI-first workflows. You're not afraid of the tools — you just want a practitioner's guide, not a beginner tutorial, on how to make the transition without rebuilding your habits from scratch.

• The Team Lead — Your team is already using AI tools but everyone's doing it their own way, leading to inconsistent quality, duplicated effort, and no shared standards. You need a common methodology — spec-driven development and Agent OS — that your team can adopt as a unified workflow rather than 10 individual experiments.

• The Ambitious Newcomer — You've seen vibe coding videos on YouTube and you understand the potential, but you're smart enough to know that building real products requires more than stringing prompts together. You want to learn how serious builders actually use AI from day one, not pick up bad habits you'll have to unlearn.

• The Bootstrapped Founder — You're building something yourself, juggling product decisions, design, and code. You don't have the bandwidth to stay on top of every new AI tool release. You need a trusted practitioner who filters the noise, teaches proven workflows, and builds in public so you can see exactly what real usage looks like.

About Your Instructor: Brian Casel

Brian Casel is a multi-time bootstrapped founder, product designer, and teacher who has spent over 16 years building software products from scratch. He began his career as a freelance web designer, taught himself the craft, and progressively built — and exited — a series of product businesses without outside funding.

His first major product, Restaurant Engine (launched 2011), provided ready-made websites for restaurants and became an early real-world example of the productized service model. He sold it in 2015 for low six figures. He then founded Audience Ops, a done-for-you content service for SaaS and B2B companies that grew to a team of 25, served hundreds of clients, accumulated several million in revenue, and sold in September 2021 for high six figures. He subsequently built ZipMessage, an async video messaging tool, which he rebranded as ClarityFlow in 2023 — a client communication platform he continues to operate today.

Key Credentials & Accomplishments:

✅ Three successful bootstrapped exits: Restaurant Engine (2015, low six figures), Audience Ops (2021, high six figures), and ZipMessage — all built without venture funding

✅ Creator of Agent OS — an open-source system for injecting codebase standards into AI coding agents, available on GitHub and actively maintained under the Builder Methods umbrella

✅ Host of Bootstrapped Web, a long-running podcast (2014–2024) co-hosted with Jordan Gal, covering the unfiltered reality of bootstrapping software businesses — featured on Apple Podcasts

✅ Guest on Startups for the Rest of Us (episodes 208, 331, 474), Mixergy, Bean Ninjas Podcast, 6 Figure Creative, and other entrepreneurship podcasts — discussing productized services, SaaS transitions, and bootstrapping

✅ Creator of the Productize course, teaching freelancers and founders how to package services into scalable, systematized offerings — one of his first educational products before shifting focus to Builder Methods

✅ Founder of Builder Methods (launched 2025), a training platform specifically for professional developers and founders making the transition to AI-first development workflows

What Problems Does Builder Methods Solve?

“I've been using AI coding tools for months but I'm still just prompting and hoping — there's no real system to what I'm doing” — Builder Methods addresses this directly through spec-driven development, the methodology at the program's core: spending time planning collaboratively with your agent before writing code, so every session starts with a structured spec rather than a vague request.

“Every Claude Code session I start from scratch — the agent doesn't know my codebase standards or conventions” — The Agent OS workshops teach you how to build a persistent system that injects your codebase standards into every AI session, so your agent builds your way regardless of which tool you're using.

“I'm a developer who knows my tools but I have no idea how to actually run multi-agent workflows or autonomous builds” — The program has dedicated lessons on Claude Code Subagents, Custom Subagents, Agent Teams, and a full workshop on Building with Autonomous Agents that walk through real autonomous workflow setups, not toy examples.

“I can build simple features with AI but real product work — complex features, UI design, database changes — still feels risky and unpredictable” — The project ride-along sessions show complete, unscripted feature builds from spec to polished result: video library, member profiles, series features, PDF generation. Watching the real process — including the decisions and adjustments — builds pattern recognition that tutorials don't provide.

“I don't know if I should use Claude Code, Cursor, or some other tool — there's a new one every week” — Brian's approach is tool-agnostic at the methodology level: spec-driven development and Agent OS work with Claude Code, Cursor, or any AI coding tool. The program teaches you the underlying workflow principles so you're not starting over every time a new tool releases.

“My team is using AI but everyone's doing it differently — there's no consistency in our output or quality” — The spec-driven development methodology and Agent OS give teams a shared standard: the same spec format, the same codebase context injection, the same checkpoint workflow. Builder Methods Pro includes a team membership plan specifically designed for coordinated team adoption.

What Makes Builder Methods Different

• Built by a practitioner who ships real products, not a content creator — Brian Casel is actively building ClarityFlow, Agent OS, Design OS, and other tools using the exact workflows he teaches. The ride-along sessions aren't scripted — they're real builds with real decisions. This creates a fundamentally different learning context than watching someone build contrived tutorial examples.

• Methodology-first, tool-second approach — The course is built around spec-driven development as a transferable workflow discipline rather than a specific tool's feature set. This means the core skills remain valuable as AI tools evolve, rather than becoming obsolete when Claude Code or Cursor updates their interface.

• Agent OS and Design OS are actual open-source tools, not just concepts — Unlike courses that teach abstract principles, Builder Methods gives you two real, maintained open-source systems (Agent OS on GitHub, Design OS in development) that you can implement in your own projects immediately.

• Builder Stories provides real peer context, not curated success stories — The interview series with Arvid Kahl, Brennan Dunn, and Colleen Schnettler presents unfiltered conversations with working indie builders navigating the same transition — the struggles, the pivots, the things that didn't work — rather than polished case studies with pre-determined happy endings.
