PESQA, a platform we built for a client
PESQA is an Argentine sport fishing platform. Guides and lodges get a listing, a dashboard and the option to take deposits through Mercado Pago. We designed and built it end to end.
PESQA has over 3,000 automated tests (3,072 as of September 28, 2026). On PESQA: access rules on every database table, an isolated internal admin panel with two-factor authentication and automated security checks on every change. We design and test on a phone first, because that’s where your customers see you. Structured data and clear answers that Google and AI search engines can read and cite. This website is built the same way.

Questions about your project
Which one do I need: a website, a store or a platform?
To present your business and get inquiries, a website or a landing page. To sell products online, a store. If your idea needs user accounts and payments, a platform. If a process is done by hand, an automation. We work it out on the call.
How much does a website, a store or an app cost?
A landing page starts at US$950; a website, at US$2,500; an online store, at US$2,000; an automation, at US$1,500 plus maintenance; and an app or platform, at US$12,000. Reference prices as of October 2026; the final price goes in your proposal.
Do I own the code?
Yes. Your domain and accounts are in your name from day one. The code and designs become yours once the project is finished and paid. On an app or platform, if you decide to stop, you keep the code you paid for.
What happens if you deliver late?
On landing pages, websites and stores, if a delay is our fault, you get 10% off for each week late, up to 30%. The clock starts once we have the deposit, the kickoff interview and access to your accounts.
How can you deliver in weeks?
We lock the scope before we start, take on up to 2 projects a month, and the same team designs and builds. No one waits on anyone else to move forward.
Do I have to write the copy?
No. The Landing page in 7 days and the Website in 14 days include the copy. We write it from what you tell us in the kickoff interview, and you review it before it goes live.
Do you use AI?
Yes, to build and check our work. But AI never answers you: a person does. It never decides: our team makes the brand, strategy and quality calls. And it never makes up facts: every result figure on this site has a date and a source.
Are hosting and the domain included?
No. You pay for them directly, separately from the project price, so they always stay under your control.
Do you work with businesses outside Argentina?
Yes. For businesses in other countries, prices are in US dollars, we issue an export invoice and we work on Buenos Aires time.
