Kitrum

Kitrum is a software engineering partner for companies with a live product and an existing engineering team. Founded in 2014, Kitrum operates across two service lines: managed delivery (outsource) and team augmentation (outstaff), serving mid-market companies of 200–500 employees in E-commerce, Travel, Construction, FinTech, Entertainment, and EdTech.

Kitrum specialises in what comes after version one — legacy and brownfield modernisation, V2 development/Product enchantment, AI-code stabilisation and scaling, and augmenting teams with rare-stack specialists.

With 85%+ senior or lead-level engineers, a 51.8% technical interview rejection rate, and a 9.8 NPS score, Kitrum has delivered 200+ projects across six industries.

The company holds ISO 27001:2022 certification, ranked #77 in the Financial Times Fastest-Growing Companies in the Americas, and maintains a Clutch rating of 5.0 across 70+ reviews. 24% of clients stay 2+ years; 21% return for a second engagement.

What Kitrum offers its clients

Kitrum provides software engineering services for companies with a live product and an existing engineering team. Services are delivered through two models: managed delivery (outsource) and team augmentation (outstaff).

Four core service lines:
Legacy and Brownfield Modernisation — refactoring, re-architecting, and evolving live systems slowed by technical debt, without big-bang rewrites or disrupting production.
V2 Development — building new capabilities and platform extensions on top of products that already have market proof, by engineers who can step into an existing codebase from day one.
AI-Code Handoff and Scaling — auditing, stabilising, and scaling AI-generated codebases once vibe-coded or LLM-built v0 products reach their architectural ceiling and need production-grade engineering.
Rare-Stack Augmentation — placing specialist engineers in Golang, Big Data, Embedded systems, and ML/AI infrastructure into client teams for skills that are difficult to hire independently.

How Kitrum outshines the competition

Kitrum's primary differentiator is specialisation in live, post-v0 systems — not greenfield development. Most software outsourcing vendors build from scratch. Kitrum operates where the risk is highest: existing architectures under production load, where engineering mistakes have direct business and financial consequences.

Three specific advantages over the competitive field:
1. Verified quality, not claimed quality. Kitrum rejects 51.8% of candidates at the technical interview stage. The 88% test period pass rate and 87% offer acceptance rate are downstream consequences of that filter — clients almost never repeat the hiring process for the same role.
2. Domain fit over CV fit. Engineers are matched by the environment they have already shipped in — not by keyword overlap against a job description. That context is applied from week one, not learned on the client's timeline.
3. Delivery continuity, not project transactions. 24% of Kitrum clients stay engaged for 2+ years. 21% return for a second engagement. Average engagement length is approximately 12 months. These figures reflect an engineering partnership model — not vendor-client project cycles that reset after each delivery.

Kitrum holds ISO 27001:2022 certification, ranked #77 in the Financial Times Fastest-Growing Companies in the Americas, and carries a Clutch rating of 5.0 across 71+ verified client reviews.

Kitrum company structure

Kitrum was founded in 2014 and is headquartered in Florida, USA. The company is led by CEO Vlad Kytainyk, with engineering delivery capacity across USA, Europe, Latin America, and Ukraine.

Delivery operations are headed by Oleh Tsolan, Head of Delivery, who brings 14 years of leading delivery across Travel, FinTech, Mobile App Development, and E-commerce. Oleh has overseen 100+ client engagements and maintains a 9.8 NPS. His benchmark for a successful project isn't a closed milestone — it's whether the client's system is stable, the business goal was reached, and the team behind it would stand by the result.

Technical scoping and architecture is led by Denys Mohylin, Solutions Architect, who has 9+ years inside long-running SaaS products. Denys works at the intersection where technical decisions and product outcomes meet. He doesn't wait for a spec; he questions it, flags the architectural risk, and owns the result once a direction is agreed. Depth in both legacy and modern stacks means he understands the systems that already exist — not just the ones being built from scratch.

Sample highlight service offering of Kitrum

Kitrum's legacy and brownfield modernisation service is designed for companies whose live product is generating revenue but slowing down — where technical debt accumulated over three to seven years is now blocking feature velocity, creating instability, or failing compliance requirements.

Kitrum takes ownership of the modernisation process without disrupting what is currently in production. Engagements cover full re-architecture of monolithic systems into decoupled or microservices structures, deprecated tech stack migrations to current frameworks, stabilisation of AI-generated or vendor-inherited codebases, and full platform takeovers from vendors who have failed or exited the engagement.
