At Lazarev., our UI/UX designers craft web app user experiences tuned to delivering a faster time to value. We offer a custom-tailored approach and ultimate flexibility to each web app project.

- By concentrating on user tasks and objectives, we ensure that the app's content and navigation are logically organized. This results in a clear visual hierarchy, lowered bounce rates and a streamlined navigation flow.
- We ensure that target audience can derive tangible benefits from the web app and complete their jobs to be done faster and more smoothly. This enhances user experience and contributes to faster onboarding and heightened retention rates.

Custom app design agency for a wide range of industries
Whether you’re building an app for managing records, accounting, automation, project management, or any other daily operations, we back you up with our holistic web application design services. Our web app designs and app development expertise span different industries, enabling us to bring fresh value, instill trust, and increase conversions in your operations.
Who we are and why teams like yours work with us
We exist for B2B teams under pressure to turn an AI roadmap into visible product usage, expansion, and a safer story in front of the C‑suite and investors. If design isn’t moving revenue, adoption, or retention, it’s decoration. We design to avoid that. Since 2015, we’ve shipped 600+ products and earned 120+ awards for work on complex, data-heavy tools: fintech platforms, AI copilots, decision engines, and vertical SaaS. Our work has helped clients turn “we have AI features” into “our customers actually use and pay for them.”
We started designing AI products in 2017, long before “AI-native” became a buzzword. With 30+ AI products shipped, we focus on the hard part most teams struggle with: making complex intelligence feel simple, trustworthy, and obviously valuable in a demo, a POC, or a QBR. We’re a 40+ person team of UX strategists, product designers, and analysts who treat design as a business function. Every engagement is anchored to the metrics you care about: AI feature adoption, activation and retention in key accounts, time-to-decision in core workflows, and upgrade/expansion tied to AI-powered plans.

We operate on a simple principle: if you're not measuring design against business outcomes, you're wasting money.
What sets us apart from a typical agency or a single in-house hire is pattern recognition at scale. We’ve seen what works – and what quietly kills adoption – across hundreds of AI and data-heavy products. That lets us spot failure modes early, bring proven interaction patterns to your team, and reduce the risk that your next AI release is another unused toggle in a settings menu.
We start with research not because it’s “best practice,” but because designing without understanding your users, your market, and your revenue model is just guessing with nicer pixels. From there, we collaborate with your product, AI, and design leaders to define where AI should show up, how it should behave, and how to make it obvious, safe, and monetizable.
If you’re a Head of AI, Product, or an AI-native founder who needs AI capabilities to be seen, understood, and used now, not someday, we’re built to be that partner.
How to design a web app: our process
We collaborate with diverse clients across industries such as FinTech, Web3, e-commerce, retail, and beyond, so our style is molded by specific objectives and preferences. Yet, a fundamental aspect consistently guides our design process: a human-centered approach.
When it comes to web application design services, our methodology is not confined to a fixed set of traits. Our style is molded by your specific business needs.
01
Conducting UX research
Our web app design user journey begins with the initial phase, where we dive into understanding the project's goals, who it's intended for, and the market it operates in. UX designers conduct thorough user research, analyze competitors, and gather requirements to outline the project's scope and objectives.
02
Building wireframes & prototypes
At this design stage, we craft wireframes and prototypes to sketch out the web app's design and functionality. This phase enables us to envision how the application will be structured and how users will interact with it, opening the door for early feedback and fine-tuning.
03
Crafting visual design
After completing the extensive UX research and user experience design phases, our web designers take the reins in shaping user interfaces. However, before delving into visual design, it's essential to establish the preferences. To accomplish this, we create moodboards that effectively communicate the desired visual directions and create web application examples.
04
Moving to the app development
Once the product is designed, tested, and refined, our web app designer gathers all the insights collected throughout the design process — such as customer journey maps, user flows, design visuals, sketches, components, guidelines, prototypes, and style references — and then passess all of this to the engineering team, whether it's your in-house team, our partnered development agency, or Lazarev.'s Webflow developers.
05
Testing and iterating
We carry out a Design Quality Assurance once the web application is coded to ensure everything is spot-on. We put the digital product through testing to pinpoint and fix any bugs, usability concerns, or performance hiccups. User testing is instrumental in gathering feedback and insights for making additional refinements.
