For performance, growth and full-service marketing agencies
You run your marketing agency. We run the data behind it
intellix.one is the data team behind your marketing agency. We build and run a marketing data warehouse for each of your clients - every ad platform, the website, GA4, the CRM - collected in one place your client trusts and you report from. You keep doing the marketing. We stay accountable for whether the numbers are right.
Server-side tracking, ad-platform cost imports, GA4, CRM identity stitching, a BigQuery warehouse and client reporting - set up per account and run for you.
One standard, every account
Every client gets their own warehouse. Every client gets the same standard. Adding an account is adding a row.
Where accounts are lost
Nobody leaves because the creative was fine
They leave because after eighteen months nobody can say plainly what the spend did. Three sources, three answers, and a monthly call that turns into a debate about the numbers instead of the marketing.
Whose number is right
Google Ads claims one figure, GA4 another, the client's backend a third. You spend the call defending the gap instead of the work.
Nobody owns the setup
Tracking gets patched by whoever had time that sprint. When something breaks quietly, it stays broken until a whole quarter looks wrong.
You optimise on what the platform can see
Blocked pixels, lost consent, no revenue fed back from the CRM. The algorithm buys against a fraction of the truth, and the budget pays for the rest.
The delegation
Your marketing agency doesn't need a data hire. It needs a data team it can hand this to
The usual options are asking a media buyer to become an analyst on the side, or hiring one data person who turns into a bottleneck across every account. We're the third one: senior data people working behind your agency, per client, at your pace. You keep the relationship and the credit. We keep the pipelines running and answer for whether the numbers hold.
What excellent data changes for a marketing agency
Keep
Clients stay when you own the foundation
When the warehouse, the pipelines and the reporting run under your agency, leaving stops being a creative decision and becomes a migration. The reporting argument disappears, because both sides read the same numbers from the same place. And what you delivered is on the record in the client's own data - not in a slide you built.
Perform
Clean, joined data buys better results with the same budget
Ad platforms, website behaviour and CRM revenue in one model gives you attribution you can defend and optimisation against real outcomes instead of proxy conversions. It also gives the platforms better signal to buy on: complete conversions, real customer values, audiences built from what actually happened. Less budget lost to tracking that quietly broke.
Win
A data foundation is a pitch nobody else is making
Every other marketing agency on the shortlist pitches creative and media buying. Almost nobody pitches what the client will actually be able to see. Bringing a data foundation to the table wins the technical buyer, the finance-minded buyer and the client who has been burned by numbers before - and it supports a retainer that isn't priced off ad spend.
What each client gets
One warehouse per client, built the same way every time.
Nothing here is a platform you rent a seat on. It runs in a cloud project the client owns, which is exactly why it survives a change of agency, a change of tool, or a change of your mind.
Collected
- Google Ads (incl. MCC and Performance Max)
- Meta
- Microsoft Advertising
- GA4
- First-party website tracking
- Server-side tagging
- HubSpot and other CRMs
- Shop and backend data
In the warehouse
- A BigQuery warehouse in a project the client owns, with the raw imports kept intact.
- Cost, clicks and impressions from every ad platform, reconciled against what the platforms report.
- Identity stitched across web sessions, ad clicks and CRM records, so a lead has a source and a customer has a value.
- Clean marts on top of the raw data, so every report reads the same definitions of the same words.
What comes back out
- Reports and dashboards per client, written so a client can read them, carrying your agency's name.
- Conversions fed back to Google and Meta with real values instead of browser guesses.
- Customer Match audiences built from warehouse segments and synced to the platforms.
- Monitoring, so a broken tag is something we tell you about before the client finds it.
How we get there
Five phases, walked per account
The same path on every client, in the order that holds. Most marketing agencies want to start at Activate. It only works when the four before it are done.
- 01
Centralize
Every source into one place per client: ad platforms, website, GA4, CRM, backend.
- 02
Trust
Reconcile it, monitor it, and say plainly which numbers hold and which ones do not yet.
- 03
Access
Put it where people work: reports the client reads, a warehouse your team can query.
- 04
Activate
Feed it back: conversions, customer values and audiences to the platforms buying the media.
- 05
Operate
Keep it running as platforms change, and stay accountable when it drifts.
How we work with your marketing agency
Behind you, not next to you
- You keep the client relationship. We are your data team, and we are happy to stay invisible.
- Reporting goes out under your agency, in your format. Your name is on the work.
- Or we join the client call and answer the technical questions directly - some marketing agencies prefer that.
- One account or the whole portfolio. Start with the client where the numbers hurt most.
