Rails Business

Ryan and Brendan talk through the growing pains of AI-assisted development — including fatigue, increased confidence in bigger code changes, and what happens when you stop paying for expensive APM tools and just build your own. Ryan walks through how he used Claude to identify memory pressure, fix N+1 queries, and cut his Heroku costs significantly in just a few days. They also dig into the real tradeoffs: maintenance burden, over-optimization, and why you still need to understand what Claude is telling you before you run anything on a live database.

Scott Werner (Sublayer) returns to discuss how rapidly AI and agentic coding have is changing.  The hosts and Scott dig into why niche tools are increasingly getting replicated by developers and hobbyists with "good enough" custom solutions — while complex enterprise platforms may actually have more staying power. Scott shares what he's seeing at the Artificial Ruby meetups. They also cover Stripe's "forward deployed" AI role, the reality of AI consulting, growing trust in AI-written code, and orchestration tools like Fabro for defining repeatable AI workflows.

The hosts explore whether “data is the new moat” in SaaS and argues that data alone—especially customer data—is rarely defensible as extraction and migration get easier. Instead, moats increasingly come from clear product vision, differentiated approaches, integrated systems, and how well apps enable AI and humans to interact with structured data. They contrast niche SaaS with broad platforms like HubSpot and Salesforce, discuss pricing model changes driven by AI costs (moving beyond per-seat to metered/credits), and predict reduced reliance on traditional UIs as chat and CLIs become efficient interfaces for AI-to-backend communication.

The hosts once again discuss the recurring theme of AI’s impact on development workflows.  They discuss various topics, including: 

• Increased PR volume from AI-assisted coding and whether traditional pull request reviews are still necessary. 
• Should AI be used earlier for pre-PR review and stronger CI guardrails for performance and security. 
• What is the role of automated testing, and are they even more important as code generation accelerates?

The hosts discuss how AI-assisted coding has massively increased their output, creating a new bottleneck: cognitive load, PR review, testing, and getting work shipped. Ryan discusses splitting time between finishing near-complete work, advancing a few large architectural initiatives, and handling ongoing support.  Brendan talks about his productivity system using Claude to manage his time using local markdown files to help stay on top of things. They also cover risks of AI automation, permission scoping, subagent/approval bugs, and conclude with a renewed optimism that AI raises abstraction, increases competition, and pushes SaaS to adapt via execution, moats, and AI-ready APIs.

Today we discuss lessons from our previous episode with John Nunemaker, focusing on the Conductor tool and how multi-workspace, multi-agent workflows can speed up coding and bug fixing. Brendan shares his experimenting with parallelizing six Rollbar error fixes at once by generating prompts and running them in separate Conductor workspaces. They compare this with a one-agent-at-a-time workflow and debate whether closed-loop setups (ports, databases, dependencies) could make parallel work trustworthy and reduce context-switching costs. They also cover using full Honeybadger/XML reports for faster debugging, using Claude Code from a phone to create PRs, challenges syncing session history, and broader AI product strategy like APIs/MCP, and RAG.

John Nunemaker returns to discuss how fast AI tooling has changed and argues tech leaders should adopt Claude Max (defaulting to Opus), set up agent-friendly local environments, and roll that out to their teams. He shares how his company built an internal “brain” using LibreChat as a self-hosted interface, enabling non-engineers to query company data and generate insights like weekly support summaries from various sources. The conversation also covers worktrees and Conductor for parallel, isolated dev environments.

In this episode, Kyle Keesling, co-owner of PASS Testing and long-time solo Rails developer, shares how PASS grew from a college web design side project into a niche software and training business for the Underground Storage Tank (UST) industry. The conversation covers why they kept the products as two apps connected by a read-only private API, what makes compliance software hard, and how they modeled flexible equipment and inspection data—evolving from STI to Rails delegated types. Kyle also discusses early scaling pains around billing and payments, how feature requests are prioritized with help from their CRO and a contractor, and how tools like Claude Code are changing his workflow while maintaining PR-based review and safer deployment practices.
