01 — What we build

A full software team. Four practices. One company.

You hire one team and get the full stack — AI engineers, product designers, mobile and web developers — working from one brief, in one channel, against one roadmap.

02 — Industries

Sector experience that compounds.

We've worked across regulated and unregulated industries — bringing pattern recognition, compliance know-how and reusable infrastructure to every new engagement.

03 — Process

Four stages. Fixed deliverables. No mystery box.

Every engagement — whether a 6-week prototype or a 12-month build — moves through the same four stages. You always know what week you're in and what comes out the other side.

A full stack, kept opinionated on purpose.

NetYolk doesn't write proposals — they write production code. We had a working agent in our hands by week three, not a slide deck about one.

07 — Questions

Frequently
asked.

Don't see yours? Drop us a line — we usually reply within a business day.

How fast can we start?

Usually within 2 weeks of signing. We hold one open pod every quarter for a "lightning" start, which can begin inside 5 business days when the brief is tight.

Do you sign NDAs and handle sensitive data?

Yes. Mutual NDAs are standard. We're SOC 2-aware and routinely work under BAAs for healthcare clients. We can also run engagements fully in your cloud and tenancy.

What if we already have an in-house team?

Most of our work is alongside in-house teams. We integrate into your tooling — your Linear, your repo, your Slack — and ramp down as your team levels up. We measure ourselves on making ourselves unnecessary.

Who owns the IP?

You do. 100% of code, designs and model artifacts are transferred to you at the end of each phase. We retain rights to anonymized case-study material only.

Will my product become outdated when the AI landscape shifts?

We build with a model gateway layer so providers are swappable. When a new SOTA model lands, you flip a config — not a quarter of engineering.

something good.
