03Better together
Some projects need both sides.
Flow and Dev share founders, standards and one process. When a project needs a product and a website, one team carries it from start to launch, with no hand-off between agencies.
- Scenario 01Flow Dev
Launching a SaaS
Dev builds the product: the app, the dashboard and billing. Flow builds the website that explains it and turns visitors into sign-ups.

Your website needs to do more
Keep the Webflow site your team already edits. Dev adds what Webflow can’t do on its own: client portals, logins, payments and integrations.

Bringing AI into your business

01
What is Remenex?
Remenex is a founder-led digital agency from Niš, Serbia. It works through two divisions: Remenex Flow, which designs and builds websites in Webflow, and Remenex Dev, which engineers custom software, web applications, SaaS products and AI solutions.
02
What is the difference between Remenex Flow and Remenex Dev?
Remenex Flow builds websites: web design, Webflow development, landing pages and redesigns. Remenex Dev builds software: custom applications, dashboards, SaaS platforms, MVPs and AI integrations. Both divisions are run by the same founders, so a single project can use both.
03
Should I choose Remenex Flow or Remenex Dev?
Choose Flow if you need a marketing website, landing page or redesign that your team can edit itself. Choose Dev if your project needs logins, data, payments, integrations or AI features. If you are not sure, write to info@remenex.com and we will point you to the right side.
04
Can Remenex build both a website and a software product?
Yes. A common example is a SaaS launch, where Remenex Dev builds the product and Remenex Flow builds the marketing site. One team plans both, so design, copy and code stay consistent and nothing is lost in a hand-off between agencies.
05
Who will I work with?
You work directly with the three co-founders: Djordje Ivanović (Head of Development), Aleksa Jovanović (Technical Lead) and Mihailo Petrović (Lead Designer). There are no account managers in between.
06
Do you work with clients outside Serbia?
Yes. Remenex is based in Niš, Serbia, and works with clients around the world, largely through Upwork, as well as with companies in Serbia. Projects run remotely, in English or Serbian, with clear written updates and calls when they help.
07
Which technologies does Remenex use?
Websites are built in Webflow. Software is usually built with TypeScript, React and Next.js, Node.js on the back end, PostgreSQL for data, and modern LLM APIs for AI features. The stack is always chosen to fit the project.
08
