MarTech Stack Design & Implementation
Digital Transformation / MarTech Stack Design & Implementation

A MarTech stack that connects marketing spend to revenue

MarTech audit, platform selection, stack architecture, and implementation -- designed around your CRM as the revenue system of record, not as an afterthought added at the end.

Why MarTech Stack Design & Implementation projects fail

01

Five marketing tools that do not speak to each other

Email platform, ads manager, analytics, CRM, and social tools -- all operating in silos. No single view of what is working. Every campaign report requires manual consolidation across platforms.

02

Marketing spend cannot be attributed to revenue

The marketing team knows how many leads they generated. Nobody knows which of those leads became customers, what the associated revenue was, or which campaigns actually drove pipeline.

03

Stack chosen by tool, not by outcome

Each tool was purchased to solve an immediate problem. There was never a design decision about how they would work together. The result is overlap, data inconsistency, and redundant spend.

04

CRM treated as a destination, not the hub

Data flows into the CRM but nothing meaningful flows back to marketing platforms. Audience segments are built manually. Personalisation is guesswork based on demographic assumptions.

What is included

Everything in this service

MarTech Audit

Inventory every tool in the current stack -- purpose, annual cost, usage level, integration status, and contribution to data quality. Identify overlap, capability gaps, and redundant spend that can be eliminated before adding anything new.

How it works

Our delivery process

01

Stack audit

Inventory every tool, integration, and data flow in the current marketing technology estate. Quantify overlap and redundant spend.

02

Architecture design

Design the target stack with CRM as the hub -- bidirectional data, clear attribution, no overlap, and a defined data flow for every touchpoint.

03

Tool selection

Confirm or replace tools based on requirements -- objective evaluation against criteria, not vendor relationships.

04

Implementation

Configure platforms, build integrations, and connect attribution in the designed sequence with testing at each stage.

05

Attribution validation

Validate that marketing spend is connecting to closed revenue in the CRM and that the attribution model produces trustworthy results.

Client results

All case studies

We were running 16 marketing tools and still could not attribute a single deal to a specific campaign. Celumai reduced us to 9 integrated tools and connected every campaign to pipeline. Marketing attribution accuracy went from 0% to 84% of pipeline having a complete source history.

C

CMO

B2B SaaS Company

The stack Celumai designed costs less per month than our previous stack -- and for the first time we can show the board a single number connecting marketing investment to revenue. That conversation changed the status of marketing in our leadership team overnight.
