Technical teams trust GrostifyLatam · USA · Europe

We build digital products with judgment.

We're not just another vendor. We're the technical ally that tells you this yes, this no when you're making decisions you'll pay for (or earn from) years down the line.

We don't take just any project. We work with teams where we can be an ally, not just a vendor.

Salvalo

Discover surprise packs near you

Every day, local merchants lose sales during low-traffic windows. Every day, thousands of people pay full price for products they could have accessed for less. Salvalo closes that loop. A circular-economy platform that connects merchants with conscious consumers through surprise packs in strategic windows. Customer app, merchant app and back-office, all operated in Venezuela. Built and operated by Grostify end-to-end.

Don't take our word for it.

“We built Salvalo to solve two converging problems: merchants losing sales during low-demand hours and consumers overpaying. Mobile app for customers and a back-office for our merchants, operating in Venezuela and expanding into Latin America. What we value most: the team's sense of ownership.”

Abrahan Mendoza

CEO, Salvalo

“We came to Grostify to build the mobile app. We left with a technical team that understands the business. The PoS integration, the AI agent and the active retainer: everything shipped as we defined it in discovery, no surprises. I don't recommend them for marketing. I referred them to Crol because they deliver.”

Francisco Rongel

CEO, ContoPay

“Crol is an established ERP, with clients that depend on it every day. Grostify came in without trying to rewrite anything. They added the RAG-powered AI layer and the mobile module on top of what we already had, without breaking what works. It's rare to find technical teams that know where to stop.”

Alonso Saiz

CEO, Crol

Building software shouldn't take a year.

Discovery, build and operation. In weeks, not years.

Start discovery

Week 1–2

Deep discovery.

  • check_circleTechnical document: scope, stack, risks
  • check_circleEstimates with high, mid and low scenarios
  • check_circleYou decide before signing the build

Week 3+

Build with live code.

  • check_circleWorking staging from week one of build
  • check_circleWeekly demos on the real product, not slides
  • check_circleTests and CI/CD from the first commit

Production

Continuous operation.

  • check_circleRetainer with agreed response SLA
  • check_circleReal metrics in a dashboard, not monthly reports
  • check_circleWe iterate on data, not opinions

Three* ways we're not your average dev shop.

*there are more, but these are the ones that change how the project actually goes.

Judgment before hands.

We tell you this yes, this no before a single line of code gets written. Deep discovery, honest scope, and the technical calls you'll be paying for years after — made with reasoning you can audit.

How we scope →

End-to-end, no handoffs.

Mobile, web, backend, APIs, AI agents with RAG, CI/CD, deployment. One team builds the whole stack — so nothing falls between vendors, and the people deciding are the same people shipping.

What we build →

An ally, not a vendor.

Signed scope, milestone-based payments, and a cancellation clause that protects both sides. We sit on your side of the table — which is also why we'll turn down projects where we'd only be cheap hands.

How we engage →

WHO WE BUILD FOR

Four kinds of teams. One thing in common: they want judgment, not just hands.

Each comes in at a different moment. We meet them where they are — and tell them honestly when we're not the right fit.

Audience 01

Tech companies that need specific capabilities.

Startups in scale-up, scale-ups and established tech companies that need a specific capability done well: API QA, third-party integrations, AI/RAG consulting, or development against a clear spec.

How we plug in →

Audience 02

Professionals with a running business.

Doctors, lawyers, coaches, consultants with an operating business who need their full digital suite: web, mobile app, online payments, automations, brand and marketing — in one package.

The digital suite →

Audience 03

Technical founders ready to scale.

You already have a product running. You need an ally to scale with quality and bring judgment to the big calls — stack evolution, AI integration, infra, performance, and what to stop building.

How we partner →

Audience 04

Entrepreneurs with an idea to develop.

You know you need to take the digital leap but not where to start. We help you define what to build, evaluate viability, plan the MVP and ship the first product without burning the runway.

How we start →

Ready to build with judgment?

30-minute call. We listen first, then tell you honestly whether we're the right ally for what you're building.

No pricing in cold conversations — every proposal is scoped to your project.
