About CUMDEV

We're marketers who got tired of vanity metrics

CUMDEV was built around one idea: agencies should be judged on pipeline, not on how good the slide deck looks.

Our approach

We run lean: a small, senior team across strategy, content, paid media, and engineering — so every client works directly with the people doing the work, not an account manager relaying messages.

Numbers over vibes

We report cost-per-qualified-lead and pipeline impact, not just impressions and reach. If something isn't working, you'll hear it from us first.

Senior team, always

Every engagement is run by senior strategists — no account gets handed off to a junior team once the contract is signed.

Built to compound

We prioritize channels and content that keep paying off months later, not one-off campaigns that reset to zero.

Plain-language reporting

Monthly reports you can actually read — what happened, why, and what we're doing next. No jargon padding.
