Cauã Cunha, Co-Founder & CFO of Zarp Studio

Every week across Florida, talented tradespeople spend fifty hours in the field building roofs, replacing air handlers, laying pavers, and managing subcontractors, only to lose their hard-earned margin in the back office. They know how to price materials, pass inspections, and lead a crew through a August heatwave. Yet when they step off the job site, they face a wall of disconnected software bills, unpredictable marketing retainers, and digital systems that were never designed for the schedule of a working contractor. As Co-Founder and Chief Financial Officer of Zarp Studio, and Founder and CEO of License Fix School, Cauã Cunha (often spelled Caua Cunha in English press and search directories) has spent years working directly with Florida tradespeople at the exact point where field mastery meets business execution.

Based in Orlando, Florida, Zarp Studio builds high-converting websites, local SEO engines, paid acquisition funnels, and Explore ZarpOS exclusively for construction and home services companies. While CEO and Founder Diego Kelme leads Zarp Studio's software architecture and AI engineering, Cauã Cunha anchors the company's financial strategy, unit-economics discipline, and deep operational roots in Florida's licensed contractor community.

The Reframe: Why Field Skill Alone No Longer Protects Contractor Margins

Talk to ten experienced contractors in Orlando, Tampa, or Jacksonville and nine will tell you that quality workmanship and word-of-mouth should be enough to keep their schedules full. Five years ago, that was largely true. Today, holding onto that belief is one of the fastest ways to let a newer, more aggressive competitor capture your zip codes.

Cauã Cunha first witnessed this pattern inside the Florida contractor licensing arena. When he founded License Fix School in Orlando in 2022, he met veteran builders with ten or fifteen years of hands-on field experience who were failing the state computer-based exams required by the Construction Industry Licensing Board (CILB) and the Florida Department of Business and Professional Regulation (DBPR). Those builders did not lack trade knowledge. They failed because knowing how to frame a building or install a commercial HVAC system is a completely different skill from navigating a timed, computer-based Pearson VUE testing interface and indexing thousands of pages of code books under clock pressure.

The exact same gap happens after a contractor earns their state license and launches or scales their company:

• Knowing the trade does not mean owning the local search territory where homeowners look for emergency repairs or high-ticket replacements.
• Buying more software logins does not fix financial visibility when your ad spend, lead tracking, estimating, and invoicing live in separate systems that never reconcile.
• Paying a generalist marketing agency does not build an asset if the agency cannot tell you your true cost per booked estimate or your net margin by service line.

Quantifying the Drag of Disconnected Tools and Untracked Spend

From a CFO's perspective, the biggest silent killer inside a $1M to $10M contracting business is not labor cost or material inflation. It is unmeasured operational leakage across marketing and administration.

When a contractor stitches together a website vendor, a pay-per-lead directory, a standalone CRM, a separate invoicing tool, and an answering service, three financial leaks happen simultaneously:

1. Subscription and Retainer Bloat: The shop pays $2,500 to $7,000 per month across fifteen to twenty separate software subscriptions and vendor retainers without a single unified dashboard showing return on investment.
2. Speed-to-Lead Revenue Loss: High-intent callers from Google Search or paid ads hit voicemail or wait hours for a callback while the owner is on a job site, turning a $400 acquisition cost into a zero-dollar outcome.
3. Working-Schedule Friction: Tools designed for desk-bound corporate teams go unused by field estimators and foremen because the interfaces are too slow and complex to operate from a truck cab between appointments.

Think about the personal toll this takes on a trade owner's week. You work from 6:30 a.m. to 6:00 p.m. managing crews, inspectors, and suppliers, and then you spend your evenings at the kitchen table trying to match bank deposits against ad invoices and unanswered web leads.

Proof in Execution: The License Fix School Pearson VUE-Inspired Portal

Before advising contractors on how to modernize their digital operations, Cauã Cunha and Zarp Studio proved what purpose-built contractor technology looks like in production. As reported by Entrepreneur.com on October 2, 2026, License Fix School partnered with Zarp Studio to engineer and launch a custom, Pearson VUE-inspired online student portal for Florida contractor candidates.

Rather than forcing working tradespeople to sit through rigid, outdated classroom lectures, Zarp Studio engineered a web platform around the actual daily rhythm of a contractor's week:

• Full Timed Exam Simulators: Modeled directly on the computer-based testing layout so candidates build muscle memory before exam day.
• Bite-Sized Mobile Flashcards: Built for 15-minute study windows in the truck between job sites or after dinner.
• Bilingual Video Instruction: Clear, field-focused lessons in English and Spanish covering Business and Finance, Contract Administration, Project Management, Roofing, HVAC, and Solar.
• Construction Math & Reference Navigation: Step-by-step modules that turn complex open-book code lookups into a repeatable system.

License Fix School is a BBB Accredited Business and an active member of the Orlando Chamber of Commerce (operating independently and not affiliated with Pearson VUE, DBPR, or CILB). You can inspect how Zarp Studio engineered this platform and other trade systems when you See Our Contractor Work.
