I'm a content specialist at Fively keen on writing fresh articles that can help out business and tech specialists. I love to conduct research, hold interviews, and spotlight sophisticated tech issues.

Fively CEO Alexey Kalachik shares the company’s journey, unique DDD approach, tech expertise, and passion for emerging AI tech in a fresh interview with SafetyDetectives.

In a recent exclusive interview with SafetyDetectives, Alexey Kalachik, CEO and co-founder of Fively, offered a behind-the-scenes look at how his company is reshaping the software development landscape. From Fively’s humble beginnings as a small team of five passionate engineers to a powerhouse of custom software and AI-driven solutions, it has already become a trusted digital partner for startups and enterprises across the globe. Fively’s unique DDD approach, future-proof architecture, and passion for emerging AI tech — all revealed in a fresh interview with Alexey for SafetyDetectives.

A Mission Rooted in Excellence and Simplicity

Fively’s origin story began in 2018 with a close-knit group of five senior engineers who shared a common goal: to build high-impact digital products in a human-centered work environment, free from unnecessary bureaucracy and rigid corporate structures.

This developer-first mindset quickly struck a chord with clients seeking not just technical expertise, but true partnership, said Alexey. Today, Fively collaborates with companies across the US, UK, and Europe, delivering everything from scalable SaaS platforms and eCommerce systems to Chrome extensions and enterprise automation tools.

Full-Cycle Development for Startups and Global Enterprises

Fively’s services cover the full product lifecycle — from ideation and MVP design to engineering, deployment, and long-term support across key industries like E-commerce, FinTech, InsurTech, Cybersecurity, Healthcare, EdTech, and Real Estate. Startups rely on the team to move from idea to market quickly, while larger enterprises look to Fively for modernization, scalability, and integration support, shared Alexey.

Notably, Fively has made a name for itself in GreenTech as well, building platforms that drive sustainable change. From the Cycle e-bike rental service, operating in 85+ European cities, to nature-restoration apps like Veritree, the company is supporting forward-thinking startups that tackle climate change with digital solutions.

Transparency at Every Stage

For Fively, building great software starts with building trust, and that means keeping clients informed and engaged. “Transparency and clear communication are at the heart of everything we do,” Alexey explained. Every project gets a dedicated manager, a shared dashboard with visible milestones and backlog, and constant access to the entire team — from daily standups to Slack updates.

Importantly, Fively empowers startups and SMBs to make the most of their development budget through smart, cost-efficient solutions. This budget-conscious approach helps their clients move forward with confidence, knowing their resources are being used wisely and efficiently.

Future-Proof Architecture and Long-Term Thinking

Alexey believes that great custom software isn’t just about what works today — it’s about what will work tomorrow.

Fively applies engineering best practices using robust tech stacks like Python, Node.js, and React, alongside modern approaches such as CI/CD pipelines, microservices, and serverless frameworks like SST and Amazon Q. Fively’s long-term engineering mindset also extends to business logic: their experts help clients define user roles, data architecture, and monetization strategies to ensure their apps evolve into fully mature platforms.

Embracing AI, Blockchain, and Emerging Tech

Alexey also mentioned that one of Fively’s most exciting frontiers is artificial intelligence. The company has already delivered advanced AI solutions in the fields of natural language processing, test automation, and predictive analytics. Technologies like TensorFlow, Pandas, and LangChain power their latest innovations.

In addition to AI, the company is exploring blockchain and Web3 technologies, especially for use cases like digital identity management and supply chain transparency. Fively’s team has hands-on experience building dApps and smart contracts, and continues to expand its blockchain R&D capabilities.

The company is also investing in no-code integrations and browser extension development — tools that empower businesses to prototype, test, and scale at lightning speed.

A Culture of Curiosity and Impact

Fively’s success is grounded in more than code. At its core, the company is about curiosity, craftsmanship, and meaningful work. With a strong track record, a global client base, and a clear eye on the future, Fively is poised to continue helping businesses innovate and succeed in a rapidly evolving digital world.
