Universal Analytics stopped tracking over a year ago. Events are inconsistent, conversions are miscounted, and nobody fully trusts the numbers it produces.
BIG DATA & ANALYTICS FOR B2B SAAS
Big data analytics that turns scattered marketing data into one number you can trust
GA4, your CRM and every ad platform, unified into one attribution model — built and maintained by the team that also ships the tracking fixes, not just the dashboard.

You'll meet me — not a sales rep. I check your GA4 and tags before every call.

THE SITUATION
You have the tools. You still can’t answer a simple question about your pipeline.
You can't say with confidence which channel — SEO, paid, content, outbound — is actually driving revenue. Attribution is broken, and nobody can prove what's working.
Leadership wants a dashboard showing marketing ROI. You have GA4, a CRM and three ad platforms — and no single source of truth to build it from.
Google, LinkedIn and Meta are all running. Nobody can say which one is pulling its weight, so budget gets split evenly instead of where it performs.
Marketing, sales and product data sit in GA4, the CRM, ad platforms and spreadsheets that don't talk to each other. Every report starts with reconciling numbers, not acting on them.
Someone set up tracking eighteen months ago and moved on. Nobody currently owns the data model, the naming conventions, or whether the numbers are still accurate.
WHY GROWSTON
Most analytics vendors build you a dashboard. We also fix what feeds it.
A dashboard built on broken tracking just reports the wrong numbers faster. Growston pairs the strategist who designs your data model with the engineers who fix the GA4 events, the GTM containers and the CRM sync underneath it — inside your business, not alongside it.
A typical analytics vendor
- Builds a dashboard from whatever data you hand them
- Reports each platform in isolation, one export at a time
- Hands you a PDF or a one-off Looker Studio link
- Treats analytics as a monthly reporting task
- Recommends fixes in a deck you forward to your dev team
Growston
- Audits the tracking first — GA4, CRM, ad platforms — so the dashboard is built on data that's actually accurate
- Unifies GA4, CRM and ad-platform data into one model tied to pipeline
- Ships a live dashboard plus the server-side tracking and event fixes that keep it accurate
- Treats analytics as infrastructure — instrumented once, monitored continuously, owned by a named strategist
- Ships the GTM and GA4 fixes directly — because we are also the engineering team
WHAT WE DO
Full-stack analytics and data strategy for B2B
Growston’s Big Data & Analytics service unifies the data you already have — GA4, CRM, ad platforms, product usage — into one model, then ships the tracking fixes and dashboards that keep it accurate.
Data audit & unification
We map every data source you have — GA4, CRM, ad platforms, spreadsheets — and unify them into one model your team can trust.
GA4 & event architecture
Clean event tracking and conversion setup, built for how B2B buyers actually move through a long sales cycle.
Server-side tagging & tracking infrastructure
GTM configuration and server-side tagging that improve data accuracy and survive ad blockers and cookie restrictions.
Dashboards & reporting
Looker Studio dashboards tied to pipeline and CAC payback, not a wall of charts nobody opens.
Behavioral & funnel analysis
Heatmaps, session recordings and funnel mapping that show exactly where visitors and leads drop off, and why.
Data strategy & fractional analytics leadership
A senior analytics strategist who sets the data roadmap and reports it to your board, without a full-time hire.
HOW IT WORKS
From scattered data to a live system in four steps
Every step produces something you keep — whether or not you continue with us.
01
Audit
A full review of the current data setup: which sources are tracked, which are guessed at, where events are broken, and where the CRM and ad platforms disagree with GA4.
You receive
A written findings document naming the gaps and the quick wins — yours to keep regardless of what happens next.
02
30/60/90 Plan
A sequenced plan connecting the audit to one data model and a reporting cadence, scoped to your team's current maturity, not a generic BI rollout.
You receive
A roadmap your CEO or board can read in five minutes.
03
Build & Launch
The embedded team — analytics strategist and, where scoped, a developer — unifies your data sources, fixes the tracking, and builds the dashboard inside your Slack and your CRM.
You receive
A live, working analytics system, not a deliverable list.
04
Optimize & Report
Ongoing monitoring for tracking drift, monthly reporting tied to the metrics your board actually asks about, and a quarterly review where you can challenge our direction.
You receive
A live dashboard and a written narrative — what changed, why, what's next.
Let's meet
Meeting first, written proposal within 3 business days.
HOW THE FIRST MEETING WORKS
We do the homework before we meet
We analyze your site before we meet — so the conversation starts at your numbers, not at zero.
Before the meeting: We review what's public about your marketingsite, positioning, search visibility — before we meet.
In the meeting: 30 minutes on your growth target, what's missing, and what we'd change. Not a pitch deck.
After: A written proposal within 3 business daysscope, price, and the outcomes we'd commit to. Yours to keep either way.
No marketing function yet? The meeting covers structure, budget bands, and a realistic build timeline.

THE ALTERNATIVES
The honest comparison
| Growston | In-house hire | Generalist marketing agency | Freelancer / data consultant | |
|---|---|---|---|---|
| Cost | Fixed-scope, mid-market pricing for senior delivery | €400K–€800K/yr in salary, recruiting and ramp | Expensive, top-heavy pricing for work spread thin across clients | Cheap, but capacity caps out fast |
| Time to value | Weeks — audit to a working data model | 3–6 months hiring, plus ramp | Slow — briefs handed to juniors, fragmented internally | Fast to start, but no system behind it |
| Strategy + execution together | Yes — one team designs the model and ships the infrastructure | Depends entirely on who you hire | Rarely — analytics sold as a line item, tracking fixes billed separately | No — you still need someone to ship the GTM and GA4 fixes |
| After launch | Monitors for tracking drift and reports monthly | Maintenance mode | Account handed off to juniors | Unreliable continuity |
FIT CHECK
Who this is for — and who it is not
Not a fit if you…
- You need results in 30 days
- Have no marketing data at all yet — this service needs something to unify
- Want a one-off dashboard with no ongoing ownership of the data model
Good fit if you…
- Are a B2B SaaS, scale-up or founder-led company in the Nordics, UK, US, or expanding into them
- Have GA4, a CRM and at least one ad platform running, but no single model connecting them
- Want the tracking fixed and the dashboard built by the same team, not two separate vendors
- Are ready to give us access to GA4, your CRM and your ad accounts so we can see what's actually happening

FAQ
Before you ask
What exactly is "Big Data & Analytics," versus your GA4 Setup or Analytics Reporting services?
Big Data & Analytics is the layer that connects them. GA4 Setup gets your event tracking right; Analytics Reporting builds the dashboard; this service is the data model and strategy that ties GA4, your CRM and every ad platform together so those dashboards report the right numbers.
We already have GA4 and a CRM. Why do we need this instead of just Analytics Reporting?
Because a dashboard is only as good as the data feeding it. If GA4, your CRM and your ad platforms disagree — which they usually do — Analytics Reporting will just visualize the disagreement faster. This service fixes the underlying data model first.
How is this different from hiring a BI consultant or a data analyst?
A BI consultant typically builds what you ask for and leaves. We audit the tracking, fix the GA4 events and GTM configuration ourselves, build the data model, and stay on to monitor it — because we’re also the engineering team, not just the analyst.
Do you build the dashboard, or just tell us what it should look like?
We build it. Recommendations in a PDF are what most analytics vendors sell; Growston ships the Looker Studio dashboard, the server-side tracking, and the event fixes it depends on.
Can you work with our existing stack, or do we need to rip it out and start over?
In most cases, no rip-and-replace. We work with GA4, GTM, your existing CRM and ad platforms, and fix what’s broken rather than starting from zero — unless the audit shows the current setup genuinely can’t be salvaged.
You're based in Warsaw — can you operate at Nordic pace and directness for a data project?
Yes. Growston is built specifically to serve Nordic and English-speaking B2B teams — data projects included. You’ll get direct findings, no padded timelines, and a strategist who reports what the data actually shows.
How fast will we see a working dashboard, not just an audit?
The audit takes 1–2 weeks. Build & Launch typically follows in weeks, not months — you’ll have a live, working system before the engagement’s first full reporting cycle.
