Hard To Reach Audiences



Some audiences are easy to find. Others are hiding behind niche job titles, tiny incidence rates, specific locations, sensitive criteria or a brief that makes everyone quietly stare at the ceiling.

That’s where we come in. Acumen Fieldwork specialises in hard-to-reach audience recruitment for market research, helping researchers find the right people for complex qualitative, quantitative and healthcare projects.


  • Niche and low-incidence consumers
  • B2B professionals and senior decision-makers
  • Healthcare professionals, patients and carers
  • Location-specific and regional audiences
  • Vulnerable or sensitive participant groups
  • Complex quotas and tightly defined profiles
  • Participants for qualitative, quantitative and healthcare research


Finding people is only half the job. They need to be the right people. We look at feasibility, sourcing, screening, validation and attendance from the outset, then manage recruitment closely throughout fieldwork. That means better-fit participants, fewer surprises and a team who will tell you early if something needs adjusting, rather than waiting for it to become Friday afternoon’s problem.

Working with Acumen means:



  • Realistic feasibility advice before recruitment begins
  • Thoroughly screened and validated participants
  • Bespoke sourcing for niche and specialist audiences
  • Clear, regular recruitment updates
  • Hands-on management of replacements and dropouts
  • Experienced project managers who understand complex briefs
  • UK-wide consumer, B2B and healthcare recruitment


Got a very specific person in mind? Good. We like specific.

Talk to us about your project or send us your brief for a costing and we’ll work out the best way to reach them.
