FAQ

How is Grinteq different from a standard outsourcing agency?

We aren’t here to just sell you raw developer hours. We seamlessly insert high-performing teams into your product domains to scale your processes fast and optimize your costs. Think of us as a strategic partner, not just a vendor.

Do you leverage AI in your development processes?

Oh, absolutely. We actually measured this internally: by baking AI tools into our daily workflows, our teams code about 27–30% faster. For you, that translates directly into shorter deployment timelines and a much better budget.

How fast can we get a candidate?

If it’s a popular stack or framework, there’s a 99% chance we ALREADY have at least two thoroughly vetted, project-tested devs ready to jump on a call with you today. Need something rare? Let’s talk. You’d be surprised at the rare unicorns we have up our sleeves!(Plus, we can mirror your hiring approach: we’ll ask your exact screening questions, record the interview, and share Notion AI summaries so you only spend time on the best fits).

What if a developer isn't the right fit?

It happens—team chemistry is real. If the vibe or skills don't match, we swap them out fast and painlessly to ensure your product doesn't lose momentum.

What are your rates and payment models?

Super flexible. Time & Material, Fixed Price, or a flat monthly rate for an assembled team. We’ll set up whatever makes the most sense for your business model.

Are you limited to the tech and verticals in your portfolio?

Not at all! We build complex Commerce and Fintech infrastructure, but we also crush it in Mobile, Web, and Embedded software. We definitely have our favorite niches, but we treat technology as a tool to get results, not the end goal. Want a very specific stack? We’ll make it happen.

Can you help us with prototypes and testing?

Yes! We love testing ideas quickly. We can build clickable prototypes, full-blown MVPs, and fully working models so you can confidently demo your product to investors or early users.

What about design? Is it just UI/UX?

We go way beyond that. We handle graphic, web, and mobile design. On top of that, we have a dedicated creative unit that even shoots high-end promo videos for IT products. We make sure your tech looks exactly as good as it works.

Is it possible to relocate a developer or buy them out?

We’re totally open to it. If moving a key player to your in-house team makes strategic sense for your growth, let’s sit down and discuss the terms.

Engineering capacity. Built for scale.
