The story

From marketing to building software.

Alexander Montiel came to the United States from Colombia at fourteen. No degree. Learned computers at the public library on 30-minute sessions. Started in marketing doing $500 a week for nightclubs in New Jersey.

Built a marketing consultancy from scratch across 15+ industries. Managed millions in ad spend. Generated over 140,000 leads. One ad ran for three years without a single change. See the case studies.

Then AI arrived. Twenty years of marketing experience, HTML, CSS, servers, DNS - fragments that never connected - suddenly fit together. Describing what a business needs and having AI build it turned out to be the whole skill.

Now ArchiHQ builds custom software for business owners. Website, CRM, automations, marketing, AI agents. Everything a business needs to run from one place. Built for your industry. Delivered in days. You own the code.

La tesis

No es solo una consultoría. Es una fábrica.

Paul Strassmann estudió empresas desde las menos exitosas hasta las más exitosas. Todas gastaban lo mismo en tecnología - alrededor del 2% de sus ingresos. La diferencia era cómo lo gastaban. Las exitosas invirtieron en productividad operacional - software a medida que ejecuta el trabajo real. Las menos exitosas gastaron en productividad gerencial - dashboards y reportes.

En 1992, Steve Jobs citó esta investigación en el MIT y dijo: "Los PCs y Macs nunca atacaron la productividad operacional." Construyó NeXT Step - software que creaba aplicaciones operacionales a medida 5 a 10 veces más rápido. Esa tecnología se convirtió en la base de macOS e iOS. Pero en 1992, solo las grandes corporaciones podían costear software operacional a medida. La IA eliminó esa barrera.

No empezamos solo una consultoría. Construimos una fábrica. Servidores AWS son el hardware. BEAM y Elixir son la planta. Agentes de IA son los robots. Una Biblioteca de conocimiento reutilizable hace cada proyecto más rápido que el anterior. Cada sistema que entregamos mejora el siguiente.

El mercado de software a medida es de $53 mil millones hoy, creciendo a $376 mil millones para 2035. Estamos en el espacio entre agencias caras que cobran seis cifras y SaaS genérico que hace el 80% de lo que necesitas. Un fundador con una fábrica entrega ambos. a una fracción del costo.

The vision

Own your software. Not rent it.

Every business runs on software. The SBA recommends that small businesses own and control their technology. But most businesses rent it. CRM here. Website there. Marketing somewhere else. Five different subscriptions that don't talk to each other. Cancel any of them and you lose everything.

We believe the software that runs your business should belong to you. Not to a SaaS company. Not to an agency. To you. If you sell your company, the software goes with it. If you cancel, you keep it all.

AI changed the economics. What used to cost six figures and take months now takes days. One founder with AI can out-deliver an agency twice the size. Solo-founded startups surged from 17% in 2017 to 36.3% of all new companies in 2025. That is not a theory. That is the market moving.

The mission: give every business owner custom software built for their industry, delivered in days, owned forever. Your AI talks to your business through our intelligence layer. Your data runs on our servers 24/7. Three access modes: AI, dashboard, or offline. Built for you. Owned by you.

What I believe

Three principles I won't compromise.

Built for you. Not a template.

Every system is custom-built around how your business actually works. Not a SaaS subscription you force your workflow into.

You own everything. Forever.

Full source code is your intellectual property. Cancel anytime, keep it all. Your software is an asset, not a monthly bill.

AI builds it. The founder makes it right.

AI handles the repetitive engineering so the founder focuses on architecture and quality. Speed comes from automation, not shortcuts. Every system is reviewed before it ships.

How we work

AI builds fast. The founder makes it right.

You don't need to understand how the software gets built. You just need to describe what your business needs. Voice note, text, screenshots. However you communicate best.

The speed comes from AI-assisted engineering. the same work that takes a traditional team 3 months compresses into a week. But the judgment is human. Every architecture decision, every business logic choice, every deployment is made by the founder.

No meetings. No calls. No project managers. No junior developers. One founder who understands both the technology and the business side. 10+ years of marketing experience across 15+ industries. AI connected the rest.

That is what you get when you hire ArchiHQ. Not a team of strangers. Not a template. Custom software built specifically for your business by someone who understands what it takes to run one.

FAQ

Common questions.

Founder of ArchiHQ. Came to the US from Colombia at fourteen. No degree. Learned computers at the public library. Built a marketing consultancy from scratch across 15+ industries. Then AI arrived and he started building custom software for businesses. The same approach that built his marketing career now builds software in days instead of months.

A company that builds custom software for business owners. Website, CRM, automations, marketing, AI agents, dashboards. Everything your business needs to run from one place. Built for your industry. You own the code. Not a SaaS subscription. Not an agency. Custom software that belongs to you.

Traditional agencies sell deliverables and walk away. SaaS companies rent access that vanishes when the subscription ends — one popular CRM was shut down in 2025 and 500,000 users lost their system overnight. We transfer full intellectual property: source code, data, documentation. All yours. Your AI connects to your business through our intelligence layer. Your data runs on our servers. One person builds everything using AI. Your software becomes a company asset, not an expense line.

Not even a little. Most clients send voice notes from their car. Describe what is slowing you down. We handle everything else. If you can explain the problem, that is all we need.

15+ and counting. Real estate, home services, hospitality, healthcare, legal, auto, e-commerce, professional services.
