More than 20 years in software development.
More than 20 years in software development.
Delivering digital products that matter.
Planums is led by Denys Vasylevskyi, who earned his first IT certificates in 2005 and has been designing and shipping software ever since.
Today, with the arrival of capable AI, Planums has developed a delivery model based on human expertise and agentic workflows that learn and improve every day. The result compresses what used to take quarters into weeks — without the quality compromise that used to come with that speed.
Clients are accepted selectively, and projects are chosen by fit rather than urgency.

02 — What we deliver
One studio.
One studio.
Every part of your product.
Most agencies hand you off between teams. We don’t. From the first conversation to the App Store listing, the same hands ship your product — and the same person stays accountable, end to end.
Business Analysis
Requirements, user stories, process mapping. We turn a fuzzy idea into a clear, buildable specification.
Product Design
Brand systems, UX research, UI design. Interfaces that are timeless, intuitive, and built to scale.
Web Engineering
Modern stacks, fast performance, clean code. Marketing sites, dashboards, web apps — built to last.
Mobile Apps
Native and cross-platform iOS & Android. From MVP to App Store launch, full pipeline handled.
AI & Agentic Workflows
LLM-powered features, agentic pipelines, internal tooling. We build what was barely imaginable a year ago.
White-Label & Integrations
Products delivered under your brand, and integrations that connect the tools you already rely on. We build it, you own the spotlight.
Support & Maintenance
Program management, monitoring, updates. The team that built your product stays to keep it healthy — for as long as you need.
03 — In-house products
Built and shipped
Built and shipped
under our own brand.
We don’t just build for clients. We build for ourselves too — and the lessons feed straight back into your project.

04 — How we work
A simple, honest process.
-
01
Discovery call
Thirty minutes. We listen, ask hard questions, and decide together if we’re the right fit.
-
02
Proposal & scope
Clear deliverables, transparent timeline, fixed budget. NDA signed on request before scope review.
-
03
Design & build sprints
Weekly demos. You see progress as it happens — no big reveal at the end.
-
04
Ship
Production-ready code, deployed to your infrastructure, documented and handed over cleanly.
-
05
Support & iterate
The launch isn’t the finish line. We stay for the long haul if that’s what the project needs.
05 — Engagement
How a Planums engagement is different.
/01
One point of contact
The same senior owner from first call to final handover. No account managers, no hand-offs.
/02
By referral only
Zero marketing spend. New clients arrive through the introduction of existing ones.
/03
Right of refusal
If a project isn’t the right fit for either side, we say so — politely and quickly.
/04
NDA on request
Mutual non-disclosure signed before any sensitive scope is reviewed. Confidentiality is the default.
/05
AI-native delivery
Senior judgement directs agentic workflows that learn every day. Quality of a craft team, speed of a much bigger one.
/06
Outcomes, not hours
Engagements are scoped to outcomes with fixed budgets. No mystery line items, no retainer creep.
