Two decades of listening carefully.
A global research partner built on one simple idea — the best decisions come from the clearest evidence, and the clearest evidence comes from asking the right people the right questions.
Research is a craft. We've spent 20 years getting good at it.
We're the specialist research partner brands turn to when they need the audiences others can't reach, the rigour others don't bother with, and the senior insight leadership others reserve for their biggest accounts.
Three principles that shape everything we do.
Research is a craft
Panels need looking after. Screeners need thinking through. Questionnaires are designed for humans, not tracking tools. Every decision we make is a craft decision.
Respondents come first
The people in our studies are contributors, not sample units. We pay them fairly, respect their time, protect their data — and maintain double the industry-average panel engagement as a result.
Specialists, not generalists
Your oncology tracker is run by an ex-pharma researcher. Your B2B segmentation is designed by a PhD in choice modelling. No one at MSG is reading from a playbook they've never used before.
20 years, measured in milestones.
A specialist fieldwork agency is born
Started with a single mission — reach the respondents other agencies couldn't, at a quality they couldn't match.
First credentialled HCP community
Launched a fully verified physician panel for compliance-ready pharmaceutical research.
Operations hubs in New York and Singapore
Scaled from single-market fieldwork into a 25-country research partner with regional project teams.
Independently audited for quality

In-house analytics practice launched
Added advanced analytics, conjoint modelling and predictive analytics — all delivered by people who understand research, not just code.
A community built around lived experience
Launched a dedicated panel for rare-disease, chronic and caregiver research, built in partnership with patient advocacy groups.
Trusted by 150+ global clients
5,000+ projects delivered. 3.2 million active panelists across six specialist communities. Still obsessed with craft.

Headquartered in London. Operating globally.
Regional hubs in New York, São Paulo, Singapore and Cape Town. Plus field teams in 18 more markets — so you get localised expertise and one consolidated project lead.
Long relationships, not quick wins.
We've worked with MSG Opinion for seven years. In that time they've never missed a deadline, never delivered sample that didn't match spec, and never treated a project like a routine job.
The MSG team is the only one I trust with advisory boards. Their moderation is thoughtful, their KOL management is flawless, and their compliance processes keep me out of trouble with legal.
I brief them once and they understand the context. That saves hours of back-and-forth and, frankly, makes the work better than I would have got anywhere else.
Let's work together.
Whether you have a fully-written brief or just a business question, we'd love to hear from you. We respond within one business day.
