How we enabled a leading FinTech company to enhance developer engagement and accelerate product adoption

About
the project

Quantillium, a leading financial data infrastructure company, offers real-time access to global stock exchange filings via a unified API. While its backend was strong, the platform’s frontend lacked clarity and didn’t fully convey its product’s depth. 

To address this, Quantillium partnered with Lazarev.agency to create a seamless user experience that makes financial data accessible, trustworthy, and relevant to developers, data teams, and decision-makers. Our task was to transform raw financial data into clear, compelling product descriptions that would increase product adoption and engagement.

Overview

Redesign for competitive edge

Quantillium’s initial challenge was translating complex, raw financial data into a clear and user-friendly experience. Through a complete redesign, Lazarev.agency turned this challenge into an opportunity to boost adoption. 

To make the platform feel more dynamic and approachable, we integrated 3D design and motion throughout the landing. Quantillium’s logo was reimagined as a three-dimensional “Q” built from transparent cubes — a direct metaphor for structured data. A glass-like effect, animated globes, and consistent 3D elements highlight both the transparency and the global reach of the service.

Animations were designed to guide attention, not distract, creating an intuitive flow that keeps users engaged. The result is a highly technological yet human experience that reinforces Quantillium’s position as a modern, advanced data infrastructure product.

First Point

Built for the professionals who drive market growth

Quantillium’s users: developers, financial analysts, and decision-makers, demand accuracy, clarity, and speed. We turned complex JSON datasets into a clear and engaging landing page experience tailored to their needs. From the very first screen, the website demonstrates the product in action: data is integrated into a structured storytelling flow, where each block highlights the API’s value and practical use cases. 

3D visuals and dynamic transitions emphasize both the scale of Quantillium’s infrastructure and the transparency of its processes. This role-focused storytelling helps each audience immediately grasp how the platform works and how it can accelerate their decision-making, turning technical complexity into intuitive clarity.

Second Point

Crafted a visual identity from the ground up for a product that had none

Before the redesign, Quantillium had no visual identity to communicate the sophistication and scale of its product. We created a design system from scratch, tailored to a developer-first audience. A dark theme enhances usability for data exploration, while a deep blue palette conveys technological precision and clarity.

Sharp typography and geometric forms reinforce a sense of accuracy, while 3D elements and subtle terminal-style animations reference real-time API workflows. This new visual language presents Quantillium as a cutting-edge technological tool and establishes a strong, recognizable digital identity.

Third Point

Adapted 3D and motion for mobile and tablet experiences

Quantillium’s audience actively accesses data on the go, which meant the landing page had to deliver the same high-impact storytelling across devices. We optimized 3D graphics, animations, and interactive elements for mobile and tablet formats, ensuring they retained both clarity and performance. Instead of scaling visuals down, we rethought their placement and rhythm to make them intuitive on smaller screens. This way, users experienced the same sense of technological sophistication and product transparency whether they explored Quantillium from a desktop, tablet, or smartphone.

To elevate user engagement and foster a deeper comprehension of the available apartments, we crafted the interactive house model within the "Selection of Apartments" section. This immersive experience empowers potential buyers to take a 360-degree tour, flipping between street and yard views with a simple toggle switch. As they hover their cursor or tap (for mobile users),  the house's specific sections illuminate, offering valuable insights into construction timelines and housing readiness. The interactive journey extends to selecting a floor and pinpointing a specific apartment with the help of a visual builder, simplifying the decision-making process and potentially increasing conversion rates.

As we explored users' perspectives further, we discovered that some don't usually leave comments online due to not remembering all the details or being short on time. These insights led us to develop tags, making it easy for people to share their experiences at places they've been. This fresh idea replaced the old star rating system with tags, offering a simpler and friendlier way to express opinions.

Acknowledging the interconnected nature of workflows, we've introduced a powerful dependencies feature to further enhance the automation of the user experience.
