Andy Houston. Revenue systems builder. Practitioner, not pundit.

Knocking on doors in Dallas selling knives and soap. Cold-calling thousands of people for life insurance. Raising real-estate capital from investors three times my age. The early years burned in a working belief that rejection is a numerical signal, not a verdict on the operator. You earn about four seconds to justify the next thirty. After that the math takes over.

Methodology shift: every funnel I have built since starts with qualification language designed to repel the wrong fit, on purpose. The "Velvet Rope" pattern in my agency lead-gen work, where deal flow at $5K to $25K only books calls from prospects targeting at least an extra $10K monthly, is a direct descendant of those door-to-door years.

A year holding space for trauma victims at a clinic in Las Vegas. The lesson that translated directly into market research: the surface complaint is rarely the real problem. The customer who says "I need more leads" almost always means "I'm terrified my business doesn't actually work." The customer who says "the website looks dated" almost always means "I'm embarrassed to send the URL to the people I want to impress."

Methodology shift: every diagnostic now runs seven layers deep before recommending a deliverable. The 180-point ICP profile I use on every engagement was built so I'd never again propose a solution to the wrong layer of pain.

Ran my own agency at $10K a day in sustained ad spend, peaking above $50K. Built three e-commerce brands past seven figures, including a metal-art DTC business that went from $10K monthly to $150K monthly in 90 days, crossed $1M within seven months, and eventually went eight-figure. Ran a 10,000 square foot manufacturing shop in Colorado upstairs from the agency office. Closed $199.5K in coaching sales in under thirty days as head coach of a hybrid program. Built CRMs for teams ranging from 20 to 250 people.

I also blew it up. I took on every adjacent business at once because I was 24 and had just made real money for the first time. The smarter move was to double down on what was working. Instead I tried to run an agency, an ecom store, and a metal shop simultaneously. The mistakes compounded into a hole the businesses could not climb out of.

Methodology shift: scope discipline became non-negotiable. The Agent Redwood twelve-component assessment, the spec-driven development workflow, and the "MVP in days or weeks, not months or never" principle all exist because I have personally paid the bill for the alternative.

After watching a dozen consulting clients get smacked by the iOS 14 attribution collapse and the Facebook ad-pocalypse, I stopped being purely a marketer. Two years self-taught into data engineering, building production systems on Pydantic, FastAPI, LogFire, and Hypothesis. Helped design an algorithmic trading system where data quality bugs cost houses, not reports. Worked tokenomics and incentive design for over two dozen Solana projects on a $500M+ TVL platform. Got rugged on a Polkadot project I helped scale from $10M to over $100M market cap, and learned the hard way that investor character is more load-bearing than the team's technical talent.

Methodology shift: marketing, data, and AI engineering now operate as one practice. Every revenue system I propose ships with a working observability layer, type-safe data contracts, and property-based tests. Boring reliability is the unfair advantage at the small-business price point.
