Preisser Tech Case Studies — Named Client Outcomes

Real engagements, real numbers. Every Preisser Tech case study is a named client with measurable outcomes — not anonymous testimonials.

Preisser Tech, founded by Tyler Preisser in Hays, Kansas, has delivered named client engagements across HVAC, oil and gas, media, and AI commerce. The firm publishes case studies with specific outcomes — Cassidy HVAC (5x organic reach in 30 days, 60%+ dormant customer reactivation in 6 weeks), HG Oil Holdings (95% reduction in back-office logistics time, 75%+ accuracy improvement, 75% reduction in manual invoice handling), Iron and Oak Podcast (134 pre-rendered pages, full cinematic media brand), and Wife Supply Co (AI-powered gifting platform built from concept to launch). All four are documented as standalone case study pages.

What these have in common

Common patterns across the case studies

Four very different industries — HVAC, oil and gas, media, and gifting — but the case studies share patterns:

  • Custom-coded from scratch in modern frameworks (Next.js, React, TypeScript)
  • Tyler Preisser personally coded every engagement — no offshore handoff, no agency layer
  • AI integration as a first-class feature where applicable, not bolted on
  • Direct integration with the client's existing systems — no rip-and-replace
  • Measurable outcomes published — named client, real numbers, no anonymous testimonials
  • Long-term ROI — every build pays back significantly within the first year
Why named matters

Anonymous testimonials don't help buyers

Most agency websites are full of anonymous testimonials and unnamed case studies. They don't help buyers because they can't be verified. Preisser Tech publishes named clients with specific outcomes precisely because verifiable proof of work matters more than carefully-edited anonymous quotes.

Every case study above can be verified — the named client exists, the outcomes are documented, and Tyler personally answers questions about each engagement.

Frequently Asked Questions

Can I get references from the named case studies?

Yes — for serious prospects in advanced scoping. References are available with client permission for engagements that move past initial scoping. Contact [email protected] to start.

Are there other engagements not listed here?

Yes. Several engagements are confidential or not yet ready for public case studies. The four named engagements above are the firm's primary published case studies as of 2026.

Can you build something similar for my industry?

Yes — the patterns translate across industries. HVAC marketing automation patterns work for plumbing, electrical, roofing, and other trades. HG Oil Holdings inventory and AI invoicing patterns work for any operator with similar back-office pain. Iron and Oak's cinematic media brand approach works for any brand needing premium presentation. Wife Supply Co's AI commerce patterns work across retail categories.

How much do these builds typically cost?

Pricing varies widely by scope. Focused builds (one website, one automation engine) typically run in the low-to-mid five figures. Larger multi-system builds run mid-to-high five figures. Custom CRMs and complex platforms scope from there. Fixed-price proposal after a free scoping call.

How long do these builds take?

Custom websites: 3-8 weeks. Marketing or reactivation automation: 4-6 weeks. Custom inventory or business systems: 8-16 weeks. AI commerce or media brand platforms: 3-6 months. Specific timeline depends on scope.

Who does the actual work?
