// the problem

Good businesses held back by bad tech.

You built something real. Your revenue proves it. But somewhere along the way, the tools that helped you grow became the ceiling. We've heard it before — because we've fixed it before.

"Our software is from 2011. No one on my team fully understands it anymore."
"We lost a major client because our portal looked like it was built in 2008."
"I pay IT contractors every month and still can't get a simple dashboard."
"We can't hire a full-time CTO just to manage what we already have."

// 01 — services

Three ways we make your tech work for you.

Each engagement is scoped around your business reality — your timeline, your budget, your team. We don't upsell. We engineer what you actually need.

01 / 03

MVP Design & Engineering

From Concept to Revenue in 4–6 Weeks.

We take your idea and engineer a fully functional product — premium UX, secure authentication, and integrated payments included. No guesswork. No delays.

Ideal for: Founders who can't afford to spend 6 months building the wrong thing.

02 / 03

System Modernization

Turn Technical Debt Into a Competitive Advantage.

We rebuild outdated software and manual workflows into modern, AI-ready cloud infrastructures — faster, cheaper to maintain, and built to scale.

Ideal for: Established businesses losing money to software that was never built to scale.

03 / 03

Fractional Product Leadership

Senior Product Expertise. Zero Overhead.

Strategic oversight for your existing product. We optimize your roadmap, implement AI features, and improve retention — without the cost of a full-time executive.

Ideal for: Teams moving fast without anyone ensuring they're moving in the right direction.

// clear investment

Fixed-price engagements.
Zero surprises.

We operate on a strict 50/50 payment structure: 50% to start, 50% on final delivery. No hourly traps, no vendor lock-in. You own everything we build.

// 04 — the studio

You work directly with the people who design and build your product.

No account managers. No handoffs to junior teams. From the first wireframe to deployment, you work with David and Andres — the same two people who have shipped enterprise products for companies in 4 industries across 3 continents.

"We don't just design screens. We engineer functional, scalable business assets. That's not a process. That's accountability."

// faq

Straight answers.

How is Spiral Tech different from a typical dev agency?+

Most agencies pitch senior talent and deliver through junior teams. At Spiral Tech, you work directly with David and Andres — the same two people who designed and engineered enterprise products for Dalog and LifeSafetyPower. No account managers. No handoffs. Just senior execution from day one.

What does a typical engagement look like?+

It starts with a free 15-minute strategy call. We listen, ask direct questions, and assess fit. If we move forward, you get a written proposal with a clear scope, fixed timeline, and defined deliverables. Once you sign the contract and confirm the first payment, we schedule your kick-off call and get to work.

What does your process look like?+

Every engagement follows our 5-phase Spiral Framework — a structured 27-step process refined across 100+ projects to eliminate guesswork and deliver on time. The result: a product that's secure, scalable, and ready for real users — delivered in 4–6 weeks.

How soon can we get started?+

Most projects kick off within 1–2 weeks of the strategy call. We keep our client roster intentionally small so every engagement gets our full attention — which also means availability is limited. If you have a specific launch date in mind, tell us on the call and we'll structure the timeline around it.

How do you handle payments?+

We work on a 50/50 structure — 50% to start, 50% on final delivery. For retainer engagements, billing is monthly at the start of each period. No surprises, no hidden fees. Everything is documented in the contract before any work begins.

What if we need changes mid-project?+

Minor adjustments are part of the process and included in scope. If a requested change significantly alters the original brief — new features, major redesigns, or direction shifts — we'll scope it separately, give you a clear estimate, and move forward only with your approval. You'll never be billed for something you didn't agree to.

Who owns the work when it's delivered?+

You do — fully. All intellectual property, code, and design assets transfer to you upon final payment. You own everything we build, with no licensing strings attached.

How do we communicate during the project?+

We keep it simple and async-friendly: email for decisions and documentation, Google Drive for all shared files and deliverables. You'll always have access to the latest version of everything. For time-sensitive issues, we're reachable directly — no ticketing systems, no support queues.

Can a two-person studio handle an enterprise-level project?+

Yes — and it's an advantage. You get senior-level execution on every task, not a senior pitch followed by junior delivery. Dalog and LifeSafetyPower are both enterprise clients. The work speaks for itself.

Will migrating our system disrupt our operations?+

We design every migration to minimize disruption. The audit phase maps your operational dependencies so we can sequence work around your critical periods. Our clients stay open for business throughout.

Do you work with non-technical business owners?+

That's our sweet spot. You don't need to understand the tech — you need to understand your business. We translate your operational needs into technical decisions and explain every step in plain language.

What happens after the project is delivered?+

Every project includes a handoff period with documentation and training. Many clients continue with a monthly retainer for ongoing improvements — but there's never pressure. You own everything, and you're free to take it wherever you need.

What's the investment range?+

Engagements start at $3,000 for audits and roadmaps, scaling to $8,000+ for full modernization. Fractional PM retainers start at $1,500/month. You'll always have a clear number before any work begins — no surprises.
