Deep Node Studios is a product strategy and software development studio in Istanbul, Türkiye. We help companies decide what to build, who it is for and how it will make money, and then we build it: web and mobile applications, cloud infrastructure and AI features. We work in English and Turkish.

We are based in Istanbul. We work with companies in Türkiye and internationally, remotely or in person in Istanbul, in English and Turkish.

Funded startups and established companies launching a new digital product. Most come to us at one of four points: an idea that needs testing, a clear plan that needs building, a new product or market launch, or an existing product that has stalled. If you sit somewhere between these, we will tell you honestly whether we are the right fit.

An agency usually takes your spec and bills hours against it. We start with the business: whether the product should be built, for whom, and how it will make money. Then the same team builds it. We work as a small senior team with a vetted specialist network. If a cheaper dev shop is the right call for your stage, we will say so.

Market and competitor research, customer interviews, the business model and pricing, the go-to-market plan, and the roadmap for the first release. Which parts we focus on depends on what is still uncertain for you.

A business plan describes the company. Product strategy decides the product: who it is for, what it must do first, how it reaches customers and how it makes money. It feeds straight into what gets built.

Yes. Many engagements end with the plan. If you build with another team, the plan is written so they can use it.

Yes, if that is what the research shows. Sometimes the right call is a smaller product, a different market, or not yet. It is cheaper to hear that before a build than after one.

Most of it you can and should do yourself, by talking to real potential customers and asking for a commitment. Paying for help makes sense when you keep getting polite feedback that leads nowhere, or when you need a structured outside read before you spend serious budget. If you can get a clear answer alone, do that first.

We do not broker investors, write your deck or raise the money. Strategy work produces what investors ask about: evidence on the market and the customer, a business model that holds up, and a product plan with the risks named before an investor finds them.

Web applications, mobile apps for iOS and Android, cloud infrastructure, and AI features such as LLM-powered tools and automation. Most projects combine several of these.

Yes. We start by reviewing the code, the infrastructure and how the product is used, then recommend what to keep, fix or rebuild. Prototypes built with AI tools or by freelancers are a common starting point.

No. If you do not have a technical team, we handle the engineering and the technical decisions. If you do, we work alongside them.

A fractional CTO is a senior technical lead who works with you part-time. They own the technical direction: architecture, what to build and what to cut, the first engineering hires, and keeping the product production-grade. It is for teams that need that judgment in the room without the cost of a full-time executive. We offer it as a monthly retainer.

If you can already build and ship, you probably do not need a full-time CTO yet. What most early teams need is coverage on their weakest side, often selling and distribution, plus a senior technical hand when decisions start to outrun their time. Hiring a full CTO too early spends money on a gap you do not have yet.

Project sizes vary too much for a price list. Before any larger commitment you get a written scope, deliverables and budget. Most work is fixed-price against that scope; fractional CTO work runs as a monthly retainer and advisory by the hour. If we cannot do something well within your budget, we reduce the scope rather than the quality. For market reference, our 2026 cost guide on the blog lists typical Istanbul price ranges by project type.

It depends on the scope. A strategy engagement is measured in weeks; a first product release usually takes longer. You get the timeline in writing, alongside the scope and budget, before any larger commitment.

Send a paragraph about where you are through the contact form, or email build@deepnodestudios.com. A real person replies within one working day. We usually start with a scoped first phase that shows what the idea, the market or the codebase can support.

Defined deliverables, agreed before we start. Depending on the work, that is research and a clear recommendation, a business model and go-to-market plan, a production-grade product, or a plan to fix an existing one. No open-ended retainers dressed up as progress.

We can stay on as fractional CTO or advisors, keep building in further phases, or hand the product over to your own team.
