Common Questions

Frequently Asked Questions

Why should a startup founder choose Xenotix over a freelancer?

Freelancers deliver code. We deliver products. Xenotix brings a full team — PM, designer, developer, QA — all startup-experienced. We understand equity, investor timelines, pivot decisions, and MVP scope. A single freelancer typically can't manage all of that.

Do you work with non-technical founders?

Most of our founder clients are non-technical. We translate your business idea into technical scope, make stack decisions on your behalf, and explain everything in plain language. You focus on the business — we handle the tech.

Can I hire Xenotix as my fractional CTO?

Yes. Many of our startup clients engage us as a fractional tech team — a senior architect + developers who attend investor meetings, make tech decisions, and build the product. It's significantly more cost-effective than hiring a full-time CTO at an early stage.

What type of startups do you build for?

We've built for fintech, edtech, healthtech, e-commerce, SaaS, logistics, food delivery, and marketplace startups. If it has an app or a web platform, we've likely built something similar. Check our portfolio for examples.

How do I get started?

Book a free 30-minute discovery call. Come with your idea (rough is fine), and we'll come with questions. By the end, you'll have a scope outline, stack recommendation, and a rough timeline estimate — at zero cost.

Can you work with my existing development team?

Yes. We regularly work alongside in-house teams as an extended squad — providing senior engineering capacity, specific expertise (mobile, AI, backend), or project leadership when founders need to move faster.
