We design, develop and scale digital products that increase engagement, automate workflows, and deliver measurable business impact. From custom AI solutions to full-scale mobile app development with AI — all in one studio.
Companies spend months and significant budgets on apps and platforms — and still see weak engagement, low retention, and no measurable business impact.
The problem is rarely the technology. It's a mix of unclear product strategy, generic UX, and the absence of real automation or intelligence in the product itself. A working app is not the same as a product that grows your business.

The solution
We build systems, not just apps.
Gravity360 is a digital product studio that combines product strategy, engineering and artificial intelligence into a single team. We don't just ship deliverables — we build products designed to grow.
Every product we design is built around user behavior, measurable outcomes and long-term scalability — so the system keeps improving after launch.
Product thinking
We start with the business problem — not the feature list. Every decision traces back to user behavior and measurable outcomes.
AI integration
Intelligence built into the product — recommendations, assistants, personalization, AI automation for businesses — not bolted on as a marketing label.
Scalable architecture
Modern stacks, clean APIs and cloud infrastructure that grow with your product — not a codebase that needs a rewrite in a year.

Why Gravity360
Built for outcomes, not deliverables.
Plenty of agencies will ship you an app. Few will build you a system that keeps compounding after launch. Here's how we're different.
AI-first approach
AI isn't a feature we tack on at the end. It's designed into the product from the first wireframe — from data structure to user flow.
Product-focused mindset
We think in terms of retention, activation, and revenue — not screens delivered. Every decision serves the business outcome.
Focus on measurable results
Every engagement defines success metrics upfront. Conversion, retention, time saved, revenue lifted — we report on what moved.
Scalable systems, not one-off projects
Clean architecture, modern stacks, documented handoffs. Whether we stay for scale or your team takes over, the system keeps growing.
Selected work
Products that moved the numbers.
Three examples of how we approach AI-powered product development — and the results they delivered.
Case 01 · Mobile · AI
AI-Powered Mobile Experience
Challenge
A consumer business needed a mobile app that would convert one-time users into daily-active users — and break free from the 30-day drop-off curve.
Solution
We designed and developed a native app powered by a recommendation engine, personalized notifications, and adaptive onboarding — tuned by real user behavior.

Case 02 · Automation
AI Workflow Automation System
Challenge
An operations team was spending 40% of its week on manual document processing, routing requests, and updating internal systems — work that was slowing the entire company.
Solution
We designed an AI automation layer that processed incoming data, routed it through business rules, and connected existing tools — with a human-in-the-loop dashboard for exceptions.

Case 03 · Engagement
Customer Engagement Platform
Challenge
A subscription business was losing customers after trial — interactions were generic, notifications were noisy, and there was no system to learn from user behavior.
Solution
We built a personalized engagement platform with AI-driven content recommendations, behavior-triggered notifications, and a real-time analytics layer feeding the personalization engine.

FAQ
Questions, answered.
Common questions about AI app development, timelines, budgets and how we work. Didn't find yours? Reach out directly.
What does an AI agency do?
An AI app development agency like Gravity360 designs, builds and scales products that use artificial intelligence — from AI-powered mobile apps and recommendation engines to AI automation for businesses and intelligent assistants. We handle strategy, UX/UI, engineering and AI integration in one team, so the intelligence is part of the product architecture, not a bolted-on feature.
How long does it take to build an app?
A focused MVP typically ships in 8 to 14 weeks. A full-scale AI mobile app with backend and automation usually runs 3 to 6 months. Timelines depend on scope, integrations and the depth of AI features — we give a clear, committed timeline after the Discovery phase, not a guess at the pitch.
How much does AI development cost?
Custom AI solutions typically start around €15,000 for focused AI automation projects and scale with complexity. Full AI-powered products with mobile, backend and automation generally range from €40,000 to €120,000+. We scope every engagement around outcomes — not hours — so pricing is tied to the business impact we're building toward.
What industries do you work with?
We work with startups, SaaS companies, e-commerce, fintech, health and wellness, media, and service businesses. Our approach applies wherever AI automation, personalization, or intelligent workflows can create measurable impact — regardless of vertical.
Do you build both mobile apps and web platforms?
Yes. As a full-service digital product studio, we ship native mobile apps (iOS and Android), cross-platform apps, responsive web platforms, internal dashboards, and the backend APIs and cloud infrastructure that power them — all in-house.
Can you add AI features to an existing product?
Absolutely. Many of our engagements start with an existing product that needs AI integration — recommendation engines, chat assistants, personalization logic, or workflow automation added to a live platform without breaking what works. We treat it as a product problem, not just a tech problem.
Do you work with companies outside Greece?
Yes. Gravity360 works remotely-first with clients across Europe, the UK and the US. Most of our engagements are fully remote, with periodic in-person workshops when the project calls for it.
