An engineering company that builds software in Istanbul

Intellego Softworks is a software company based in Istanbul. We build web applications, SaaS products, system integrations, desktop software, and AI-backed products, each one shaped around how the company using it actually works.

Working code is part of the job. From the first day we decide how the product will be operated, which systems it has to talk to, and what happens when the load grows. Who can keep developing it once the team changes is part of those decisions too.

You work with the engineers directly

The people across the table in the first call are the engineers who will build the product. There is no separate team that takes the project over from sales.

We work out what is needed together and go through the technical options. The scope is written down before development starts. After that you get a version you can open and click through every two weeks, so you watch the product take shape instead of seeing it whole months later.

The team works from Istanbul. Some of the work runs online and some of it happens around the same table.

We pick the technology to fit the problem

We do not walk into every job with the same stack. First we work out the problem to be solved, the systems you already run, and where the product is going in a few years.

We build custom web applications and SaaS platforms. We connect enterprise systems to each other and write desktop applications. Data infrastructure, cloud systems, and AI features are part of the same work.

We can build a new product from nothing. We can take an existing one apart and rebuild it, or add new capability on top of a system that has been running for years.

What happens after launch is part of the job

What a piece of software is really like becomes clear when the first users arrive.

Delivery is not the end of the project for us. We build applications so they can be watched: logs, alerts, and error tracking are in place from the first day. We keep developing as performance problems, infrastructure work, and new requirements come up.

What we want to leave behind is software you can still work on comfortably six months later, when something has to change.

Services

Web applications, cloud infrastructure, AI integrations, desktop software: we build and operate across the stack.

Web Development

Web development is the step-by-step process of turning an idea into a working website: you start by defining goals, plan the pages and content, design the look and user experience, build the front-end and back-end, test and launch, then maintain and improve the site over time.

AI Solutions

Integrating AI into existing business workflows means mapping where AI adds value, choosing the right Large Language Model or AI service, and building an AI flow with clear guardrails, monitoring, and compliance so the model's outputs are controlled and auditable.

SaaS Platforms

SaaS platforms deliver cloud software on a subscription basis and, when integrated correctly, can streamline operations, reduce IT overhead, and unlock automation and analytics across your business.

Integrations

Integrations connect separate software systems so they share data and automate workflows; an integration uses APIs and webhooks to move data reliably, securely, and at scale.

Content Management Systems

A Content Management System is software that lets people create, edit, organize, and publish digital content without coding; we help make that power reliable, secure, and easy to use for your team.

Desktop Software

Desktop development builds applications that run natively on a user's computer and give deeper system control and offline performance, while web applications run in browsers and prioritize cross-device access and easy updates.

Database Management

A database is the organized place where applications keep their information; we help you design, run, and protect that data so your apps stay fast, reliable, and auditable.

DevOps

DevOps is the practice of combining development and operations so teams ship software faster and more reliably; we build CI/CD pipelines, shape infrastructure as code, and run the automation and monitoring that keep releases predictable and safe.

Consultancy

We provide pragmatic software consultancy that helps you decide what to build, how to build it, and how to run it, so you avoid costly mistakes, ship faster, and keep risk under control.

Idea to Production

Every project moves from first conversation to live product through the same six stages. We show our work at every step: no black boxes, no surprises.

Discovery

We start by listening. Through stakeholder interviews, workflow mapping, and competitive analysis we define the problem space, identify constraints, and agree on measurable success criteria. The output is a clear scope document and prioritized feature list so nothing is left to guesswork.

Design

Wireframes and interactive prototypes come first so you can see and click through the product before a single line of code is written. We design responsive interfaces, define information architecture, and validate usability with real user feedback. Architecture decisions are documented for long-term maintainability.

Development

Our engineers build in short, iterative sprints with working software delivered at the end of each cycle. We use modern frameworks, write clean and well-structured code, and integrate continuously so progress is always visible. Code reviews and pair programming sessions keep quality high from day one.

Testing

Quality is built in, not bolted on. Automated unit, integration, and end-to-end tests run on every commit. We perform load testing, security scanning, and accessibility audits to catch issues early. Nothing reaches production without passing the full test suite and manual review.

Deployment

We set up CI/CD pipelines that build, test, and deploy automatically. Infrastructure is defined as code for reproducibility. Staged rollouts, feature flags, and automated rollback ensure releases are safe and predictable. Your first production deploy is as smooth as your hundredth.

Support

Launch is just the beginning. We provide ongoing monitoring, incident response, and performance optimization. Regular health checks, dependency updates, and proactive scaling recommendations keep your product running reliably as your user base grows.

What a software company does

A software company's job starts with turning a need into a technical definition. The product is designed, built, tested, and put into production. Operating it afterwards is part of the same job when that is what is wanted. Writing code is one of those things.

Alongside the feature being asked for today, somebody has to think about how the product will change in a few years. Where the data will live, which systems it has to integrate with, and how errors will be tracked are all part of building it. So is how easily a new developer can pick the project up.

At Intellego, delivery means handing over the product together with the environment it runs in. Along with the source code we build the infrastructure that will watch its performance and its errors once it is live.

How to choose one

Two things are worth more attention than the list of technologies in the quote. Who will build the project, and what happens once it is finished.

Being able to talk to the technical people who will actually work on it, and not only to the sales team, helps on the first call. The real decisions about architecture, timing, and scope get made by that team later.

Settle who will own the source code, the cloud accounts, and the other technical assets created for the project. On a product meant to last, keeping them in the client's own accounts makes it easier if you decide to work with a different team later.

Who takes responsibility once the software is live is a separate question. Error tracking, monitoring, backups, updates, and response to an outage: whether those sit inside the development quote or are billed as a separate service should be clear before anything is signed.

Ask how you will see the project moving. We open a working version to the client every two weeks, so the project does not appear all at once at the end.

Frequently asked questions

I am looking for a local company that can build an application quickly. How fast do you deliver?

It depends on the scope. For a web or mobile application that has been clearly defined, we ship the first usable version in 6 to 10 weeks on most projects. On a smaller build that solves one workflow, that comes down to 3 to 4 weeks.

The difference comes less from development speed than from how clearly the work was defined before it started. So the first stage is deciding together on the screens, the core business rules, the integrations, and the features the first version will leave out.

During development we hand over a working version every two weeks. For the parts every product needs, authentication, notifications, payments, and an admin panel, we use mature libraries and existing services where they fit.

The team is in Istanbul, so discovery and project meetings can happen face to face when that is easier.

I am looking for integrated software for marketing automation. What can you build?

On marketing automation projects the first job is usually getting the tools the company already runs to talk to each other properly. Building something new from nothing comes after that.

We build data flows between the CRM, the email and SMS services, the ad platforms, the e-commerce side, and the ERP. Something a visitor does on the site can update their record in the CRM. Particular behaviour can open a sales task or move the person into a different message sequence.

We work with HubSpot, Salesforce, Pipedrive, Mailchimp, Klaviyo, Google Ads, and Meta. We also build integrations with local services that offer an API.

Most of the work sits around connecting the APIs rather than in the connection itself. Field mapping, retrying failed operations, stopping the same operation running twice, error tracking, and the consent records that are required are all part of the system.

If an existing product covers the need, we set that up. Where off-the-shelf tools fall short, we build the integration or automation layer in between.

My budget is limited. How can I start a software project for less?

On a tight budget we do not shrink the idea. We shrink the problem the first version has to solve.

Rather than automating ten workflows at once, we pick the one that wastes the most time or earns money directly. The first phase makes that one work end to end. Once the product is genuinely being used, the rest go in one at a time.

Which parts have to be custom built also drives the cost. If a reliable existing service already solves the problem, writing the same system again has no point. We size the infrastructure to what the product needs today.

There is no harm in telling us your budget up front. We will say plainly what fits inside a given figure and what has to wait for the next phase.

What should I look for when choosing a software agency in Istanbul?

Start with whether you are meeting the people who will actually work on the project. If you will never see the people from the first meeting again once development starts, it gets hard to tell how much of what was promised will reach the code.

Ask before signing who will control the source code, the cloud accounts, the domains, the databases, and the other accounts opened for the project. Starting that conversation after the project ends creates a problem neither side needs.

What happens after launch is its own subject. Who handles error tracking, updates, and the infrastructure should be settled at the start.

Find out how often you will see the product during development. A presentation or a status report does not show where a project stands. A running version does.

At Intellego the client works with the technical team directly throughout. We keep the source code and, wherever possible, the project infrastructure in accounts the client controls, and we hand over a working version every two weeks.

How is the cost of a software project decided?

Two applications that look alike can cost very different amounts to build. The reason is usually not the number of screens but the business rules behind them and how much the system has to talk to other services.

A simple admin panel and an application with several user roles, approval flows, payment systems, an ERP integration, and automated notifications can look similar from outside. The development load is not the same.

So before quoting we work out the main user flows, the integrations, and the permission structure. The data model and what you expect operationally after launch are part of that conversation too.

Where the scope is clear enough, we work to a fixed scope and a fixed price. If the product is expected to take shape during development, a monthly model with a set amount of team capacity works better.

You do not need a technical document at the start. Telling us what you want to do, and your budget range if you have one, is enough for us to talk about the rough size of the project.
