The Gospel of the Full-Stack Madman
By Raoul Duke, reporting from the edge of the Singularity

Somewhere between the waning sanity of San Francisco and the nuclear hum of Mountain View, a new breed of founder is sharpening its fangs — not to serve the machine, but to become it.

This is no longer about selling AI widgets to law firms so some overfed partner can bill another hour sipping scotch while a junior associate copy-pastes from ChatGPT.

No. That’s the coward’s path. That’s white-collar hospice.

Y Combinator, bless its amphetamine-fueled heart, is calling for full-stack AI — not toolmakers, but warlords. This is not a startup. This is an insurrection in a blazer.

The thesis is elegant in its lunacy:

Don’t sell picks and shovels to the gold miners. Become the goddamn mine.

Take law, for example.

StartEngine’s $30M Surge — Own a Piece Before June 26

Private markets are having a moment, thanks to companies like StartEngine.

The leading alternative investing platform is helping everyday investors like you access deals once reserved for VCs and insiders, including exposure to private market titans like OpenAI, Databricks, and Perplexity.¹

How’s it going? In Q1 2025, StartEngine pulled off $30M in revenue, its biggest quarter ever (based on unaudited financials).²

But StartEngine isn’t just a middleman. The company earns 20% carried interest on select pre-IPO offerings, unlocking value for shareholders when these deals succeed.³

How can you tap into this diversification play? By investing in StartEngine.

StartEngine has crowdfunded $85M+ to date, and you can join 45K+ shareholders before the company’s current round closes on June 26.

The legal industry — a bloated, jargon-choked monstrosity powered by golf meetings, interns, and fear — is ripe for ritual sacrifice.

Why build an AI tool to “assist” them when you can build an AI firm that replaces them outright? You don’t pitch to the dinosaur. You hunt it. You mount its skull above the login screen.

This is techno-capitalism with the safeties off. No B2B SaaS niceties. No enterprise pilots. You eat what you kill. Medicine. Finance. Real estate. Journalism. (God help us.) Every slow-moving cartel ripe for a digital coup.

Full-stack means vertical integration with a vengeance. 

Your value chain is a monolith of machine logic and human delusion, dressed up as a service business. You don’t sell to incumbents. You become the new incumbent. You replace the institution.

So here’s the message scrawled in blood on the YC whiteboard:

Why build tools for the empire when you could raise an army and burn Rome?

This is not for the faint of heart. This is for founders who don’t want to help the status quo — they want to strangle it with its own legacy code.

Go full-stack or go home.

Here are 10 juicy, vulnerable, and staggeringly bloated industries that are just begging to be steamrolled by a Full-Stack AI Company — not a vendor, but a vengeful upstart looking to replace the incumbents wholesale:

1. Immigration Law Firms

The Problem: Endless forms, bureaucratic slog, overpriced attorneys.
The Opportunity: A full-stack AI immigration firm that handles visas, green cards, citizenship — end-to-end — with AI case managers, real-time updates, and transparent pricing.
Replace the lawyer. Own the pipeline.

2. Medical Billing & Revenue Cycle Management

The Problem: Byzantine codes, endless human error, fraud, and delay.
The Opportunity: A full-stack AI-powered billing operation that plugs into clinics and handles the entire stack — intake, claims, appeals — without the bloated third-party RCM hell.
Bill faster. Bill smarter. Outrun the paperwork zombies.

3. Insurance Claims Adjusters

The Problem: Slow response, human bias, error-prone decisions.
The Opportunity: Launch your own insurance company with AI-powered adjusters, pricing, and payout logic. Think Lemonade on meth, but smarter.
Don’t sell to insurers. Become one that never sleeps.

4. Residential Real Estate Brokerage

The Problem: 5-6% fees for glorified Zillow tour guides.
The Opportunity: A full-stack AI brokerage that handles listings, buyer matching, negotiations, paperwork — all without agents.
Burn the realtor. Automate the American Dream.

5. Clinical Trials & Pharma CROs (Contract Research Orgs)

The Problem: Costly, slow, error-prone human coordination of trials.
The Opportunity: A full-stack AI CRO that runs trials faster and cheaper with AI-patient matching, monitoring, data analysis, and FDA-ready reporting.
Clinical trials run by machines. Better data, faster drugs.

6. Tax Preparation (ahem, H&R Block)

The Problem: Overpriced clerical work with a human face.
The Opportunity: An AI-powered full-stack tax firm — from document ingestion to filing and audit defense — as a sleek productized experience.
“File with us — we’re not human. That’s the point.”

7. Mental Health Clinics / Therapy Networks

The Problem: High therapist costs, scheduling friction, uneven care.
The Opportunity: A full-stack AI therapy company with LLM-based therapists, human oversight, continuous mood tracking, and personalized plans.
Scalable care. Always available. Nonjudgmental by default.

8. Debt Collection Agencies

The Problem: Human-run call centers, harassment complaints, inefficiency.
The Opportunity: An AI-run debt collection firm using intelligent outreach, negotiation bots, and ethical repayment nudges — integrated with financial behavior tools.
Less "pay up" and more "let’s fix this."

9. University Admissions Consulting

The Problem: Pricey consultants, subjective advice, manual editing.
The Opportunity: A full-stack AI college counseling firm that helps students find, apply, and get into schools with optimized essay writing, application prep, and decision strategy — all powered by LLMs.
Why pay $20k for a former admissions officer?

10. Corporate Compliance & Governance

The Problem: Manual audits, human bottlenecks, expensive legal reviews.
The Opportunity: A full-stack AI compliance-as-a-service company that embeds into your org and continuously scans, reports, and flags risks — from data privacy to board governance.
AI that reads the fine print so you don’t have to.
