Websites
Sites that sell while you sleep.
A site that doesn't bring in work is an expensive brochure. We rebuild it into a conversion-first storefront that turns visitors into booked jobs, like The Azure Group with its live valuation and neighborhood pages.
Phone Bots
A receptionist that never sleeps.
Every call that rings out after 5pm is a job your competitor got. We build voice agents that answer, book, and qualify around the clock.
Telegram Bots
Automation your team can text.
The paperwork after every job is the part that eats your nights. Text the Invoice Bot and it drafts the invoice for Pedro's job, emails him, and logs it to QuickBooks in seconds.

The studio
Two builders.
CORTEX is a two-person studio that ships like a team of ten. We design, engineer, and obsess over every pixel and every millisecond, with no handoffs and no telephone game. If it carries our name, it feels alive.

Straight answers
Before you call us.
The things people want settled before they pick up the phone: timing, ownership, and what happens if it goes wrong. Answered here so you don't have to ask.
How long until it's live?
It depends on scope, and anyone who gives you a date before they know the scope is guessing. A landing page and a web app are not the same job.
If you need it sooner, say so when we talk. Timing and any rush arrangement are settled in the written quote, and a real date comes with it, before anything starts.
Do I own it, or am I renting it from you?
Pay in full and you own it outright, no monthly. The monthly plans spread that build cost over time instead, so what transfers and when is written down rather than left to assume.
Either way, ownership of the build, and who holds the domain, the accounts and the data, is settled in writing before work starts, not argued about later. Nothing you depend on gets held hostage.
What if it doesn't work out?
On the monthly plan there's nothing holding you: $0 down, cancel anytime. On the others, what happens if either side walks away is in the agreement you sign. Read that part properly, with your own lawyer if you want.
What we won't do is promise you a number. Nobody honest can guarantee rankings, leads or revenue, and “guaranteed #1 on Google” is how people get burned the first time. We'll tell you what we expect a build to change, and set it up so you can see whether it did.
Do I need to be technical?
No. You need to know your business: where the money leaks, which calls go unanswered, what customers keep asking for. That's the part we can't do without you.
We handle the rest end to end, and anything you'll want to change yourself later gets handed over in a form you can use without calling us first.
What do you need from me to get started?
A couple of short conversations, and whatever already exists: logo, photos, price list, access to your domain. If it currently lives in a filing cabinet or in your head, that's fine too.
If the copy, the branding or the photos don't exist yet, that's a line item on the quote and not a blocker: copywriting, logo and branding, and moving your old content across are all work we take on.
