What's the most ambitious project you know of or have done in claude?

Reddit · rukuto · May 26, 2026
A non-IT business owner developed a full CRM and ERM system using PHP and SQL to address performance issues with Monday.com and documentation management problems in their small business. The project required approximately 20-23 Claude project chats and 12 sessions of Claude Code, producing a system smaller than 20 MB with phase 1 nearly complete. The initiative began as a simple daily log tool but evolved into a comprehensive relationship management platform after proving effective.

Detailed Analysis

A self-described non-IT business owner has documented building a full CRM and ERM (Employee Relationship Management) system in PHP and SQL using Anthropic's Claude as the primary development tool, sharing the project on Reddit's r/ClaudeAI community as part of a broader discussion about ambitious Claude-assisted projects. The user reports completing the work across approximately 20-23 Claude project chats and 12 sessions of Claude Code, with each session consuming roughly 700,000 token contexts — representing a substantial and sustained engagement with the model's extended capabilities. Phase one of the system is described as nearly complete, with a final build size of under 20 MB, a modest footprint for a custom-built business management platform.

The project originated as a pragmatic response to dissatisfaction with existing SaaS tooling. The user cites persistent performance issues with Monday.com and difficulties managing documentation as the catalysts for building a proprietary solution. The development followed an iterative path, beginning with a simple daily log application for a small business and expanding incrementally as early versions proved functional. This trajectory — from minimal viable tool to full-featured system — reflects a pattern increasingly common among non-technical users who leverage AI coding assistants to bridge the gap between business need and software implementation.

The significance of this case lies in what it reveals about the democratization of software development through large language model assistance. Historically, building a CRM from scratch would require either significant developer expertise or a substantial budget to hire one. This user's account suggests that Claude, particularly through its Project and Claude Code interfaces, has lowered that barrier to the point where a motivated non-technical operator can architect and deploy custom enterprise software. The token volumes involved — multiple sessions each consuming hundreds of thousands of tokens — also underscore the complexity of real-world software projects and the demand for long-context reasoning in agentic coding workflows.

This development connects to a broader competitive dynamic in the AI assistant space, where the ability to sustain coherent, multi-session software projects is becoming a key differentiator. Anthropic's Claude Code product, which the user relied on heavily, represents the company's direct play for the developer and prosumer market, competing with tools like GitHub Copilot, Cursor, and OpenAI's coding-focused offerings. The fact that a non-developer completed a project of this scope speaks to the maturation of these tools beyond simple autocomplete and into genuine collaborative engineering partners. Community threads like this one also function as organic testimonials, shaping perception of Claude's practical ceiling among technically curious but non-specialist users.
