A data architecture that holds up.

Your data is scattered across ten tools, every analysis needs a manual export, and nobody really knows what it costs.
We build a single foundation: automated sources, a tested and documented model, costs under control.

Does it actually work?

-98% on data architecture costs across the audited scope

Use case data engineering 900.care réalisé par Smart Bees

A partner to 900.care for two years, Smart Bees supports the brand in structuring and exploiting its data. As the business grew, the challenge was to keep a high-performing stack while bringing infrastructure costs back under control.

Three questions we get asked

Three workstreams, one foundation

01
Workstream

How do you centralize your data sources without rebuilding everything?

We start by adding connectors for the standard sources, and build custom connectors only for the ones that don't exist. Orchestration handles dependencies and retries.

What it covers
Airbyte or Fivetran connectors
Custom API ingestion for your business tools
Orchestration, replays and alerts when a run fails
Data contracts with the source teams
02
Workstream

Which data warehouse and which transformation tool should you choose?

The warehouse choice depends on your volumes, your in-house skills and your budget. Transformation through dbt in layers keeps the model readable for analysts.

What it covers
BigQuery, Snowflake or Databricks: a costed decision
dbt modeling: staging, intermediate, exposure
Automated tests, freshness checks and documentation
Storage and compute cost optimization
03
Workstream

How do you industrialize without piling up technical debt?

The stack is assembled like a product: separate environments, code review, controlled deployment, and a metrics layer shared across tools.

What it covers
CI/CD and dev / prod environments
Access and role governance
A metrics layer reused by every dashboard
An up-to-date catalog and lineage
What does it look like in practice?

The method, in four stages

01 | MAP

Source mapping

Volumes, fields, expected freshness and how each team actually uses the data.

02 | ARCHITECT

Target architecture

Multiple environments, chosen stack, component by component, with costs and sequencing signed off in committee.

03 | BUILD

Build in batches

One business domain shipped to production per sprint (retail, digital, merchandising), tracked in Jira or your own tool.

04 | HAND OVER

Handover

Making it usable: documented code, systematic review, and a technical handbook for your teams.

What our clients say

What the teams we work with say

Data & Analytics engagement — Segment CDP

“We brought in Smart Bees to support the Segment CDP implementation, a key project for our data strategy. They were always available and quick to answer complex technical questions or to move the project along. What really made the difference was how they teach: they managed to make genuinely technical concepts accessible to the Ornikar teams.”

Data & tracking projects

“I've worked with Smart Bees on several data and tracking projects and I can only recommend them. Beyond their technical expertise, they have a real ability to understand the business stakes behind the numbers and to propose concrete solutions. I always valued their availability, their responsiveness and the quality of their recommendations.”

What we're asked most often

Frequently asked questions

Do we need a warehouse if we have little data?

Not always. Below a certain volume, a simple well-documented model in a tool you already have is enough — and we'll say so plainly.

Can you take over an existing stack?

Yes, that's the most common case: we stabilize what's there before proposing anything new.

How do you keep warehouse costs under control?

Partitioning, deliberate materializations, and monthly monitoring of the most expensive queries.

Can your deliverables be reused without you?

Yes: code versioned in your own repository, generated documentation, and a handover session with your teams.
