Who you talk to
VTA is the development brand of a small senior team led by Vinicius Ambrozio. He reads what you send, he writes the scope you sign, and he is in the channel while the system is being built.
There is no account manager relaying messages, and no junior team behind a senior face.
< track record />
How VTA got here.
From the system that runs an operation to the SaaS you sell by subscription.
Systems: Software that runs the operation.
Websites, management systems, e-commerce, bots and integrations between platforms. Delivered, running and still evolving in production.
Payments: A payment gateway built from scratch.
Seller KYC, payouts, checkout and an API with webhooks. The team integrates Stripe, Mercado Pago, BuckPay, Cakto and Paradise in production, so Pix, local anti-fraud and reconciliation are ordinary work here, not a research project on your invoice.
See the Vennox Pay caseProducts: We use what we sell.
A WhatsApp CRM, a lead dashboard with push notifications and our own SaaS products run in production. This website follows the same recipe we deliver.
SaaS: Today: your SaaS, from the MVP on.
The main focus now is building SaaS for clients: an MVP in up to 10 weeks, with a fixed-price proposal that sets scope and date. We also take over SaaS projects stuck with another team.

How a project works
Same-day reply
Write by form or WhatsApp and a person answers the same day. Not a bot, not an account manager: an engineer who will read what you sent.
Fixed-price proposal
We settle the details with you over WhatsApp or email, whichever you prefer, and send a written scope with a price and a delivery date. That document is the contract. Anything outside it is priced as a separate item before it is built.
Staged delivery
The first usable version goes live early and grows in cycles you can log into. Larger systems are split into stages.
Your code, your accounts
The code is yours, handed over with documentation. You create the project accounts, such as a Google account, and give us access, so the code, the domain and the accounts are in your name from day one. If you hire in-house later, nobody needs our permission.
