Twenty years of asking whether it actually worked
Syneractiv is a healthcare marketing analytics practice based in Stamford, Connecticut. We work with pharmaceutical brands, their agencies, and the media platforms that serve them, on one problem: establishing what marketing investment actually caused, and turning that into a decision someone can defend.
The practice
Founder Joy Joseph has led analytics and measurement organizations for more than two decades, including Chief Data and Analytics Officer at Initiative/HealixGlobal, Managing Partner at GroupM, SVP Analytics at IRI/Circana, and roles at Citibank and Ipsos MMA.
The methodological work spans marketing mix modeling, hierarchical mixed-effects econometrics, and propensity score matched lift analysis, with published work through the ARF and WARC. A working paper on advertising adstock transformations has been in circulation for twenty years.
In 2023 Joy authored the Point of Care Marketing Association's industry study on POC measurement — five months of survey work, expert interviews and empirical benchmarking, with contributors from Merck, Novartis, ZS, Publicis Health Media, PatientPoint and others. In 2025 he co-authored the follow-up that tested a fix for the central finding. Both papers are public.
We also participate in defining how healthcare media should be measured, currently through the POCMA and Media Rating Council working group on point-of-care standards. Credibility in measurement is not self-declared. It's conferred, in public, through process.
How we work
We work alongside brands, agencies, and media partners across the whole arc: developing audiences, establishing measurement plans before launch, and evaluating outcomes against methodologies defined in advance.
That continuity is the point. It removes handoffs, and it means the question answered at the end is the one that mattered at the start.
Collaboration does not require compromising objectivity. Every study follows a methodology established before any result exists. The framework, the cohort diagnostics, and the matching logic are transparent and auditable, so conclusions can be evaluated on their merits.
We name the source. Every time.
The methodology is the product. The data is an input, and which input depends on the question and on what you already have. We work on client-owned claims, licensed sources, and partner data, and we've built the measurement on all three. Where a study in this practice used a specific source, that study says so by name.
Claims are one of the most objective sources available for understanding patient pathways and prescribing behavior. They are not a complete picture: coding is uneven, some conditions are systematically under-recorded, and coverage varies by source. Our studies say where the picture thins. That's not a disclaimer. It's the difference between a measurement and an assertion.
Being able to tell you which of those applies to your data, before the study rather than after, is most of what you're buying.
Two people who let us use their names
Both engagements are described elsewhere on this site in the abstract. These are the people who ran them.
Syneractiv led a multi-phase research initiative for us on Point of Care (POC) Marketing performance measurement. Measurement is extremely important, especially within a rapidly growing channel like POC. The data, research, and insights Syneractiv helped us compile have accelerated our journey toward POC measurement excellence.
Joy @ Syneractiv led a consulting engagement for us, helping us develop high impact use cases on sponsorship audience insights and measurement. Syneractiv's approach to internal and external voice of customer, competitive capability assessment and feature prioritization, helped us put a comprehensive audience product development roadmap in place confidently. Joy is extremely knowledgeable in this space and was a pleasure to work with!
