Valas OÜ:
TEAM & AGENCY OVERVIEW

Who we are

We are a senior, tightly aligned product team that helps launch, test, and scale digital products without long-term hiring commitments.

We work in a service model (invoice-based, VAT applicable), not employment. Team setup, replacements, scaling up or down, and operational complexity stay on our side, so clients can focus on decisions instead of people management.

Based in Slovenia, we operate within the EU legal and tax framework and work with clients internationally.

We can start work within one day.

Who this model works for

  • corporates and director-level teams launching spin-offs or new initiatives
  • startups from pre-seed stage and beyond
  • founders with an existing business testing new ideas and markets
  • IT entrepreneurs with active or closed products
  • organizations operating under EU grant and public funding requirements

When our involvement creates the most value

  • there is an idea on the table, but no clear answer yet on whether to build it
  • speed matters, but you need to know you can stop if it goes the wrong way
  • you want to test ideas with code, not just ship features
  • a previous team failed and the project needs to be picked up and stabilized

How we actually work

Product, marketing, and technology do not work as separate tracks. In real projects, decisions in one area immediately affect the others. Hypotheses are tested through code, marketing signals shape product direction, and technology choices are made with real go-to-market constraints in mind.

That is also why marketing is embedded into development rather than added later. In EatBeat, product logic, user journey, and market positioning were rebuilt in parallel. In Windhub, cartography and tools were shaped directly by how sailors make decisions, not by abstract feature lists. In EMP, clinical workflows, security, and business constraints were solved together, not in sequence. This approach reduced wasted work and allowed us to test direction early, before committing too much.

The team has worked through failed handovers, regulated domains, and high-pressure situations. We learned how to step in for each other, redistribute responsibility without friction, and keep projects moving. That experience is why our communication is fast and lightweight, and why we are clear about what works and what does not.

What we are not

we don’t sell hours
we don’t stretch projects to keep billing
we don’t lock clients into people or processes

Operational Navigation & Geospatial Systems (under NDA)

Summary

Work on navigation and geospatial systems used in real operational environments, where interface decisions directly affect safety and real-world outcomes.

Users operated under time pressure and physical constraints. The work focused on turning complex geospatial data into clear, actionable interfaces that support confident decision-making.


Growth & Acquisition Cases

Large-Scale Consumer App Growth (under NDA)

Summary

Growth work for a major global consumer app focused on scaling acquisition through systematic creative experimentation and automation.

Creative A/B testing combined with AI-assisted automation delivered approximately 443K incremental downloads with an average +2.23% lift in install conversion. The focus was on building repeatable experimentation processes rather than one-off wins.


Acquisition Cost Reduction Across Channels (under NDA)

Summary

Work on reducing acquisition costs for a global consumer app across programmatic and cross-channel campaigns.

Optimizations spanned creatives, ad placements, and store-level elements such as CPP and custom store listings. This approach resulted in CPA reductions of up to 73% while maintaining scale.


Web-to-App Funnel Optimization (AI Apps)

Summary

Optimization of web-to-app funnels for multiple AI-driven consumer applications, focused on conversion efficiency.

Work was done in close collaboration with Product and UA teams. Funnel experiments delivered an average +31% lift in click-to-install rate and a 23.6% reduction in CPI across the app portfolio.


Modular Creative Testing System (AI Apps)

Summary

Design and implementation of a modular creative testing system for paid acquisition across multiple AI consumer products.

The system allowed recombination of top-performing creative elements across formats and channels, delivering up to 62% CPA reduction in tests and an 11% portfolio-wide ROAS lift.


Go-to-Market for a Privacy-Critical Feature (Robokiller)

Summary

Go-to-market support for the launch of a new privacy-critical feature in a consumer mobile product.

Product positioning, acquisition messaging, and pricing were aligned around the new feature. The launch introduced a new pricing tier and resulted in a 66.2% increase in user lifetime value.


Localization-Driven Store Optimization (Robokiller)

Summary

Improving install conversion for a specific audience segment through localized app store presentation.

Audience-specific custom store listings for Spanish-speaking users in the US led to a +5.3 percentage point increase in install conversion, without increasing acquisition spend.


Why this matters

These are projects we can openly discuss: how we entered the situation, what decisions we made, what worked, and what did not.

They reflect how we operate as a product team, not as an execution-only vendor.
