About MonteDev

Our Story

MonteDev was founded on a simple observation: most software development is slower and more expensive than it needs to be, and most companies are paying unnecessary costs to financial middlemen. We set out to fix both.

By combining Extreme Programming (XP) with modern AI tools, we help teams ship high-quality code at unprecedented speeds. By leveraging Bitcoin, we help businesses escape legacy financial systems and reclaim their margins.

We don't just consult - we partner. We embed with your team, pair program with your developers, and architect systems that last.

Our Philosophy

Simplicity

The best solution is the simplest one that works

Sustainability

Fast doesn't mean reckless. We build for the long term.

Freedom

Both in code (no vendor lock-in) and finance (no banking gatekeepers)

Transparency

No black boxes. You own your systems.

Frequently Asked Questions

We're already using AI tools. How is this different?

Most teams use AI as a fancy autocomplete. We integrate AI into XP practices - pair programming, continuous feedback, strict guard rails. It's AI with discipline.

Is Bitcoin legal for business use?

Yes, in most jurisdictions. We help you navigate compliance and reporting requirements, ensuring your implementation is both legal and optimized.

What if we're not ready for both services?

No problem. Many clients start with one and add the other later. They're complementary but independent. We often recommend starting with whichever pain point is more urgent.

How long does implementation take?

XP transformation typically takes 3-6 months for full adoption. Bitcoin integration is usually 2-3 months depending on complexity and existing infrastructure.

Do you work remotely?

Yes. We're fully remote with occasional on-site intensives if needed. Most of our work is done through video calls, shared repositories, and collaborative tools.

What's your pricing model?

We offer fixed-price projects for defined scopes, and monthly retainers for ongoing advisory. During our initial call, we'll recommend the best model for your situation.
