To choose a software development company in Istanbul, shortlist three or four firms with verified reviews and work similar to yours. Then judge them on four things: whether they question your business, not just your spec; who will actually do the work; whether they give you a written scope with a team and a timeline; and what their past clients say when you call them. Price matters less than it seems. In buyer research it decided the choice only 8% of the time (Hinge Research).

This checklist is written by Deep Node Studios, a product strategy and software development studio in Istanbul. It applies whether or not you end up working with us.

Step 1: Decide what you're buying

Before you contact anyone, decide which of these you need:

Strategy first. You're not yet sure what to build, for whom, or how it makes money. You need research and a recommendation before code.
A build. You know what to build and need a team to build it well.
A rescue or takeover. Something exists and isn't working: growth has stalled, or the code can't keep up.
Ongoing leadership. You need senior technical judgment part-time, such as a fractional CTO.

Studios differ in which of these they're good at. If you ask a pure dev shop for strategy, you'll get a feature list back.

Step 2: Build a shortlist

Directories with verified reviews. Clutch and GoodFirms list Istanbul firms with rates, minimum project sizes and client reviews. Of the Turkish firms Clutch profiles, most charge $50–$99 an hour, with minimum projects from $1,000 to $50,000 (Clutch, October 2026).
Referrals. Ask founders, CTOs and investors you trust who they've worked with, and who they'd avoid.
Similar products. Find apps or platforms like yours and ask who built them.

Aim for three or four firms. Talking to more than that rarely improves the decision.

Step 3: Check these before you sign

Check	What good looks like	Why it matters
Relevant work	Case studies with outcomes (users, revenue, time to launch), not just screenshots	Shows they've solved a similar problem
References	2–3 past clients you can call	Reviews can be curated; a 15-minute call rarely is
Who does the work	Named people with their seniority, and clarity on subcontracting	The team in the pitch should be the team on the project
Written scope	Deliverables, team, weeks and budget, in writing	Without it, every number is a guess
Pricing model	Fixed price for clear scope; time and materials with a cap for unclear scope	A mismatch here causes most budget fights
Ownership	The contract assigns code and IP to you, and you own the repos and cloud accounts	Switching teams later depends on it
Communication	Weekly demos or updates, one accountable contact, your working language	Silence is how projects drift
Handover	Documentation, deployment access, a transition plan	You shouldn't be locked in
After launch	Support, maintenance and who fixes production issues	Most cost happens after version 1

Step 4: Ask these questions on the first call

What would you need to know before you could give us a real number?
Who exactly would work on this, and what have they built before?
What would you cut first if the budget were 30% lower?
How will we see progress each week?
Who owns the code, the repos and the cloud accounts during and after the project?
What happens if we want to continue with another team later?
Can we speak to two clients from the last year?
When have you advised a client not to build something?

The last question tells you most. A studio that never pushes back will build the wrong thing on time.

Red flags

A price before any questions. A quote on day one, without discovery, is a guess or a template.
A suspiciously low number. Marketplace offers under 50,000 TL for "an app" usually mean a template, not a product built for your business. Compare with 2026 market ranges.
No written scope. "We'll figure it out as we go" works only with a budget cap and weekly demos.
They won't let you talk to the engineers. You'll be managing a salesperson, not a project.
Your accounts are in their name. Repos, domains and cloud accounts should belong to you from day one.

Is Istanbul a good place to hire a software company?

For many companies, yes. Rates run below Western Europe and the US and close to Central and Eastern Europe. The time zone (UTC+3, all year) overlaps with both Europe and the Gulf, and most studios work in English and Turkish. If you're comparing countries, see building software in Türkiye.
