FOR WHOM DV - 4 SITUATIONS

We help when technology starts to harm instead of help

01|Situation

A site that does not work for the company

⇲

Each offer is preceded by a short conversation (20 min, free of charge), in which we check if Digital Vantage is the right partner. 15-20% of conversations end with a 'buy ready' or 'go freelancer' recommendation - we don't sell a project if you can solve the problem more simply.

COOPERATION - 3 STEPS·3 steps

Your path from idea to working solution

  1. Step 01
    Talk 20 minutes (free)

    Purpose, context, constraints, budget. I check if I can help, or if it's better to recommend someone else. 15-20% of conversations end with the recommendation 'buy a ready-made SaaS, use no-code, hire a freelancer'.

  2. Step 02
    Audit + action plan (paid, £5-15k)

    Audit of current technology, milestone plan, risks, costs of 3 variants. Documentation yours - you can go with it to another provider. Paid, not a 'free offer'.

  3. Step 03
    Phased implementation + care

    Implementation in 2-week sprints. Payment by stages, not by hours. Post-implementation: care 450-1500 PLN/month or handover to in-house team.

Paid audit as a resource that you can use regardless of further cooperation. Not a 'free quote' that you invest in a vendor.

Case studies

Case studies and results of cooperation with Digital Vantage

The following examples show how we approach typical company problems - from diagnosis to implementation in stages.

WHAT DISTINCES Digital Vantage - 3 DISTINCES

Three things we do differently than a typical agency

01

We say 'don't build' when there is a ready-made solution

The first 20 minutes of the conversation is a verification of whether custom needed. 15-20% of calls end with a recommendation:

  • CRM for 10 people → Pipedrive (~£800/month).
  • Booking for 1 location → Calendly + Stripe
  • Mailing → Brevo / Mailchimp
  • Simple store → Shopify / WooCommerce

We lose 15-20% of leads per year. Customers who choose ready-made - they come back in 2-3 years when they grow out of SaaS.

02

Paid audit as a resource, not a 'free quote'

Audit 5-15 thousand zloty, architectural documentation (ERD, API contract, technical decisions, schedule) - your property. You can go to another developer.

Investors / partners / future CTOs seehow we think about architecture, not onlywhat we built. A concrete benefit: due diligence takes 1 week instead of 4-6 weeks.

03

Your repository, your property, zero dependency

GitHub Yours from day 1. License Yours (MIT or proprietary). Full documentation (architectural decisions, implementation guide, technical documentation).

Any competent programmer will take over the project in 1-2 weeks. No dependence on a vendor. No monthly fees for access to "your" code that the agency keeps.

Meet Konrad Barejko - founder of Digital Vantage

Konrad Barejko. 20+ years of corporate IT (telecom, EMEA, 50+ teams, multi-million dollar budgets, Research and Development (R&D)).

Digital Vantage is my way of applying the same operational and process discipline I've seen in corporations to companies of 30-300 people - without the corporate costs and chaos of a typical agency.

We start with a conversation in which we separate the 'cool ideas' from the things that will command a result. After the conversation, you get a concrete plan - what we do, where the risks are, how much it costs. No salesman, no follow-ups, no 'free audits' that are just an excuse.

Own servers in the EU

Dedicated servers: Warsaw, Poland, Europe (or global if the project requires it). Full control over data, compliance with RODO, no dependence on cloud provider.

Milestone billing - you pay for results

You pay after the stage delivered (3-5 stages typically). 0% prepayment, 0% billing for hours on the clock. If the stage has not been delivered - you do not pay.

Next.js + Payload CMS

Technology stack with 5+ years of production experience (Next.js, Payload, Postgres). Zero hype-driven libraries in version 0.x. After 3 years, the code still works and is updatable - no rewriting from scratch.

Ready to talk - or prefer to check it out for yourself?

Most decision makers prefer to learn about DV on its own terms first. Check a quote, take a quiz, download an industry report. Or, if you already know the topic is for us - schedule a 20-min interview.

Arrange a 20-minute interviewFirst, I want to research the topic on my own

No obligation. 20 minutes. If the topic does not make sense or can be solved more simply - I will say it straightforwardly.

TOOLS - CALCULATORS - QUIZZES

Check your project yourself

Calculators based on data from 50+ DV deployments. Decision quizzes for the undecided. No registration, no email chasing.

INDEPENDENT REPORTS - INDUSTRY DATA

Our publications - no sales, no water

Market analysis, industry audits, technical research. Each report supported by data, sources, methodology. Quoted by industry experts.

STACK - PRIMARY PRODUCTION TECHNOLOGIES

We work with technologies proven to produce

Minimum 5 years of track record, active support, stable API. Zero 0.x libraries or 'latest trends' without practice. Less hype = less code rewriting in 2 years.

FAQ - THE MOST COMMON QUESTIONS

The most common questions before the first interview

The cost depends on the scope, priorities and whether we start with cleaning up current solutions or implementing from scratch. After a brief discussion, we prepare a recommendation and scope options with an approximate estimate.

  • Company websites: PLN 3.5-15 thousand.
  • E-commerce: from PLN 15 thousand.
  • Web applications: PLN 30-300+ thousand.
  • MVP for startups: PLN 30-100 thousand.
  • Mobile applications: 40-250 thousand zlotys.
  • Automation: PLN 15-200+ thousand.
  • Consulting: audit PLN 8-25 thousand, fractional CTO PLN 3.5-9 thousand/month.

After a 20-min conversation, you get a detailed ±15% fork for your project.

No - and it's often better not to have it to begin with. If you have an idea, we start by sorting out the goal, the user and the priorities, and then we verify the assumptions, so that we don't build something that "on paper" looks good, but in practice doesn't work.
In the end, you get a concrete plan: the scope of the MVP / milestones, requirements, risks, estimation and recommendation of what makes sense to do now and what to postpone.

You have a single point of contact on the Digital Vantage side, and we select specialists for the scope of implementation (e.g. architecture, development, UX/UI, graphics, support). This keeps communication simple and implementation predictable.

Most often we start with a conversation at the earliest possible date. We plan the next steps in stages - so that we can quickly deliver the first results and in parallel maintain control over the scope and budget.

Both. We can start with one specific problem (e.g., site improvement, tool integration, automation), and if the collaboration makes sense - develop it further.

Clear direction: what to do first, what to do later, what are the risks and which option makes business sense. If the topic is on our side, we suggest next steps and an indicative estimate.

It is possible to work together on a project basis (in stages) or on an ongoing basis for care and development. The choice of model depends on whether you need a one-time implementation or continuous technological support.

Dedicated servers: Warsaw, Poland, EU. Full control over data. All Digital Vantage applications compliant with RODO as standard (anonymization, retention, export, right to be forgotten). For regulated industries (medical, finance) - we can add ISO 27001 processes.

We have worked with companies in the following industries: telecommunications, manufacturing, FMCG, finance, B2B software, public sector (most under NDA). The industry is not the most important - process discipline and architecture scales between industries. An initial conversation will clarify whether our experience fits your problem.

Let's talk about your business

20 minutes of free talk. No sales slides. No follow-ups. No 'free audits' that turn out to be sales.

If your topic makes sense - I propose a plan of action. If it doesn't make sense or can be solved more simply - I'll say it outright and recommend elsewhere.

Arrange a 20-minute interviewDescribe the topic in 2 min

Without commitment. If the topic does not make sense or can be solved more simply - I will say it straightforwardly.
