The barrier to entry for building on the ChatGPT platform is remarkably low. Using modern AI-assisted coding tools, a solo developer or small team can realistically build and ship a working Minimum Viable Product for a ChatGPT app in under 30 days. This speed allows for rapid experimentation and iteration on new business ideas.

Gamma's success ($100M ARR with 52 employees) proves an 'AI-first' approach can challenge giants. By rethinking core products like presentations from the ground up with AI, startups can create delightful, hyper-efficient products and achieve massive scale with a tiny headcount.

Low-cost AI tools create a new paradigm for entrepreneurship. Instead of the traditional "supervised learning" model where VCs provide a playbook, we see a "reinforcement learning" approach. Countless solo founders act as "agents," rapidly testing ideas without capital, allowing the market to reward what works and disrupting the VC value proposition.

Previously, building sophisticated digital experiences required large, expensive development teams. AI and agentic tools level the playing field, allowing smaller businesses to compete on capabilities that were once out of reach. This creates a new 'guy in the garage' threat for established players.

Monologue's success, built by a single developer with less than $20,000 invested, highlights how AI tools have reset the startup playing field. This lean approach enabled rapid development and achieved product-market fit where heavily funded competitors have struggled, proving capital is no longer the primary moat.

AI tools enable solo builders to bypass the slow, traditional "hire-design-refine" loop. This massive speed increase in iteration allows them to compete effectively against larger, well-funded incumbents who are bogged down by process and legacy concerns.

AI is predicted to reduce engineering costs to near-zero, enabling individuals with strong product taste to build, launch, and market SaaS companies alone. The critical skill will shift from coding to user testing and product insight, functions that AI cannot yet fully replace.

While the internet has consolidated around major platforms, AI presents a counter-force. By drastically lowering the cost and complexity of building mobile apps, new tools could enable a 'Cambrian explosion' of personalized applications, challenging the one-size-fits-all model.

The new Spiral app, with its complex UI and multiple features, was built almost entirely by one person. This was made possible by leveraging AI coding agents like Droid and Claude, which dramatically accelerates the development process from idea to a beautiful, functional product.
