Focused expertise · For agencies

You do the creative work.
We help prove it works.

Creative and brand platform are your strength. We plug in as your data & growth partner to make your product stronger — research, analytics, acquisition and retention, without scaling your team.

White-label or co-branded — you stay the face to the client.

Sound familiar?

When the client wants more than just creative.

“They want numbers, not just the idea”

Pitches and renewals increasingly go to whoever shows business impact, not just the storyboard.

“In-house analysts are expensive to keep”

A full-time research / data / CRM hire doesn't pay off on irregular load, and a patchwork of freelancers breaks quality.

“We're strong on brand, less so on the funnel”

Acquisition, retention, product analytics aren't your core expertise — but the client needs answers.

“Not enough insight to defend the idea”

Creative without audience and market data sells worse and takes longer to sign off.

What we take on

We plug in on a specific project or on an ongoing basis as your external data & growth team. You stay the face to the client; we're the expertise behind the scenes — or co-branded, as agreed.

1

Research & insight for creative

Market and competitor analysis, audience and ICP profiling, JTBD interviews, trend reports.

Output: audience & market research, ready for a pitch or to defend an idea.
2

Strategy & positioning

Brand platform, positioning, TOV, messaging framework, CJM — the analytical foundation under your creative execution.

Output: a messaging framework you can hand to the creative team.
3

Acquisition & performance

Media planning, tracking setup (UTM/GA4), SEM, A/B tests, platform integration, and performance-vendor coordination — a campaign turned into a measurable result.

Output: configured tracking + transparent reporting on campaign performance.
4

Retention & product analytics

Lifecycle strategy, trigger flows, RFM / cohorts, LTV / churn dashboards — so the client doesn't just acquire, but retains.

Output: funnel, LTV and retention dashboards to make the case to the client.
05

Data backbone for your pitches and reports

We size the opportunity, automate reporting, and build the evidence base that makes renewals and upsells easier.

Output:a “before / after” evidence base — to renew contracts and grow the account.
