PCO Partner Services — What Markely Provides

Markely Agency is a specialist B2B event marketing and congress technology agency that works as a dedicated partner for Professional Congress Organisers (PCOs). We provide the outsourced marketing, technology, staffing, and design services that PCOs need to deliver successful congresses for their associations and clients; including delegate acquisition campaigns, congress website development, abstract submission and management systems, conference mobile apps, on-site event staffing, hostess and brand ambassador services, congress branding and design, exhibitor and sponsorship marketing, and digital marketing campaigns.

Markely works with PCOs managing congresses across the UK, UAE, and Saudi Arabia, serving associations and scientific societies across medical, academic, and professional sectors.

You Run the Congress. We Provide the Specialist Capability.

PCOs are built to manage. Scientific programme coordination, abstract management, delegate registration, venue liaison, financial oversight, stakeholder communication, the operational demands of running a major congress are extensive and well-documented.

What is harder to resource in-house is the specialist capability that sits around the congress: the targeted delegate acquisition campaigns that fill the registration portal, the congress website that converts abstract authors into full registrants, the on-site staffing team that represents your association with professionalism, the design that makes your congress brand credible from first communication to final session.

Most PCOs source these from a patchwork of separate suppliers; a different agency for marketing, another for technology, a staffing company for on-site, a designer for the abstract book. Each relationship requires briefing, management, and coordination. Each supplier operates without full context of what the others are doing.

Markely provides all of it. One specialist partner. One briefing. Consistent congress identity across every touchpoint.

Built for PCOs Managing Complex Congresses

Markely’s PCO partner services are designed for Professional Congress Organisers working across:

1
Medical and scientific congresses

Annual congresses, symposia, and hybrid scientific meetings for medical associations, research societies, and clinical networks, where delegate growth, abstract volume, and sponsor revenue are the primary performance metrics.

2
Association congresses and annual meetings

International and national congresses for professional associations and membership bodies, where the delegate experience, congress identity, and year-on-year attendance growth directly reflect on the association’s reputation.

3
Academic and research conferences

Scientific conferences for universities, research institutions, and academic bodies, where abstract submission volumes, peer review management, and delegate engagement define success.

4
Industry congresses and professional summits

High-value congresses for industry bodies and professional networks, where exhibitor and sponsor acquisition, delegate quality, and on-site experience drive commercial outcomes.

Our PCO Partner Services

Delegate Acquisition & Congress Marketing

Fill Your Registration Portal With the Right Delegates

Delegate numbers are the foundation of every congress. Sponsor revenue, exhibitor decisions, association board confidence, and future congress bids all depend on consistent delegate growth, yet targeted delegate acquisition is one of the most consistently under-resourced functions in a PCO operation.

Markely runs multi-channel delegate acquisition campaigns specifically designed for the congress environment targeting the right scientific communities, clinical networks, and professional associations through digital marketing, email campaigns, LinkedIn outreach, and database marketing. We understand that the delegate for a haematology congress is reached differently from the delegate for a civil engineering symposium, and we build campaigns accordingly.

  • Targeted delegate acquisition campaigns by scientific discipline and professional sector
  • Email marketing and automated nurture journeys for abstract authors and potential delegates

Congress Technology — Websites, Apps & Abstract Systems

The Technology Infrastructure Your Congress Depends On

The congress website is often the first point of contact for potential delegates, abstract authors, and sponsors. The abstract submission and management system underpins the entire scientific programme. The congress mobile app defines the on-site experience for thousands of delegates. These are not peripheral tools rather they are the operational backbone of the congress, and they need to work.

Markely provides congress technology solutions built specifically for the PCO environment designed to integrate with your registration and delegate management workflows, compliant with your association’s branding guidelines, and supported throughout the congress lifecycle from launch to post-event closure.

On-Site Staffing — Registration, Hosting & Brand Ambassadors

Professional On-Site Staff Who Represent Your Congress With Confidence

The on-site experience begins at the registration desk. The way delegates are welcomed, directed, and supported during the congress directly shapes their perception of the association and the PCO. On-site staff are not a logistical afterthought instead they are the human face of the congress.

Markely provides professional on-site event staffing for congresses; from registration desk teams and session room managers to congress hostesses and brand ambassadors. All staff are briefed on the congress, the association, and the scientific context before arrival. They work to your congress operations manual and report to your on-site congress manager.

Congress Branding & Design

A Congress Identity That Reflects the Association’s Standard

Every piece of congress communication; from the first save-the-date to the final abstract book, carries the congress brand. Inconsistent design across these touchpoints undermines the professionalism of the congress and, by extension, the association.

Markely provides congress branding and design services that create a coherent, professional visual identity across the entire congress lifecycle, from initial branding development through to the printed and digital materials your delegates, sponsors, and exhibitors encounter on-site.

  • Congress brand identity development — logo, colour palette, typography, visual guidelines

  • Delegate bags, lanyards, badge design, and printed congress materials

Exhibitor & Sponsorship Marketing

Fill Your Exhibition Floor and Exceed Your Sponsorship Revenue Targets

Exhibition revenue and sponsorship income are the financial engine of most congresses yet acquiring exhibitors and sponsors requires a different skillset from congress operations. It requires targeted outreach to commercial organisations, compelling prospectus design, and a sales-oriented follow-up process that most PCO teams are not structured to run.

Markely provides exhibitor and sponsorship marketing services that help PCOs reach their commercial revenue targets from prospectus design and exhibitor acquisition campaigns through to sponsor recognition and on-site activation support.

  • Industry symposia and sponsored session marketing
  • Sponsor recognition across congress communications and on-site materials

Digital Marketing & Congress Promotion

Congress Promotion That Reaches the Right Scientific Community

A congress cannot rely on association membership communications alone to drive delegate registrations. Reaching the wider scientific community including clinicians, researchers, and professionals who are not yet members require active digital marketing across the channels where those communities spend their time.

Markely provides digital marketing campaigns for congresses that includes building awareness, driving abstract submissions, growing delegate registrations, and amplifying congress content before, during, and after the event.

How Markely Works With PCOs

We understand that integrating a new specialist partner into an established congress operation needs to be straightforward. Markely is built to work within your existing processes and not to replace them.

1

Congress briefing

We start with a thorough briefing on your congress: the association, the scientific discipline, the target delegate profile, previous congress performance, current supplier relationships, and your objectives for the coming congress cycle. The more we understand your congress, the more effectively we can support it.

2

Service scoping

Based on the briefing, we agree which specialist services Markely will provide for your congress — and how these integrate with your existing PCO team and supplier structure. Some PCOs engage Markely across all six service areas. Others start with one or two and expand the partnership over subsequent congress cycles.

3

Congress delivery

Markely works to your congress timeline, your brand guidelines, and your reporting requirements throughout the congress cycle. You have a named point of contact across all services, and we coordinate across our own internal teams so you don’t need to manage multiple handoffs.

4

Post-congress reviews

After every congress, we provide a performance report covering delegate acquisition results, technology performance, staffing feedback, and design output — and a recommendations document for the next congress cycle. We build partnerships designed to improve year on year.

Congress Sectors We Work In

Markely’s PCO partner services support congresses across:

Medical and clinical congresses

Why PCOs Choose Markely as Their Specialist Partner

One briefing. Consistent delivery. Briefing six separate suppliers for one congress is six times the management overhead. Markely provides all specialist services under one roof — which means one briefing, one relationship, and one team that understands the full congress context across every service they deliver.

We speak your language. Most marketing agencies do not understand the PCO world. They do not know the difference between an abstract submission deadline and an early bird deadline, or why delegate conversion from abstract author matters, or how sponsor recognition needs to work across physical and digital congress touchpoints. Markely does. We have built our services specifically around the way congresses work.

We work across UK, UAE and KSA. International congresses require on-site delivery capability across multiple markets — the same professional standard whether the congress is at ExCeL London, the Dubai World Trade Centre, or the Riyadh Front Exhibition and Conference Center. Markely provides congress staffing, technology support, and on-site design installation across all three markets.

We grow with your congress. The strongest PCO partnerships improve year on year — as Markely builds deeper knowledge of the association, the scientific community, and the delegate profile, campaign targeting sharpens, technology improves, and on-site delivery becomes more efficient. We measure success by delegate growth, sponsor revenue, and abstract submission volume — the same metrics your association board measures.

Frequently Asked Questions

A PCO partner service is a specialist external agency that works alongside a Professional Congress Organiser to provide services that the PCO does not run in-house — such as delegate acquisition, congress technology, on-site staffing, design, and digital marketing. Rather than a PCO sourcing multiple separate suppliers for each function, a PCO partner like Markely Agency provides all of these specialist services under one relationship, briefed once and coordinated internally.

Professional Congress Organisers most commonly outsource delegate acquisition and marketing campaigns, congress website development, abstract submission and management systems, conference mobile apps, on-site event staffing, congress branding and design, exhibitor and sponsorship marketing, and digital marketing. These are specialist functions that require dedicated expertise and resources that most PCO operations do not maintain in-house across their full congress portfolio.

Markely works with PCOs on both a per-congress project basis and as an ongoing specialist partner across a PCO’s full congress portfolio. For PCOs managing multiple congresses annually, an ongoing partnership typically delivers better results — as Markely builds deeper knowledge of each association, scientific community, and delegate profile over successive congress cycles. We discuss the right working model during the initial congress briefing.

Yes. Markely’s congress technology services are designed to integrate with existing delegate registration platforms, abstract management systems, and congress management software. We work within your established technology ecosystem rather than replacing it — adding the specialist front-end and marketing technology layers that drive delegate acquisition and on-site engagement.

Yes. Markely provides professional on-site event staffing for congresses in the UK, UAE, and Saudi Arabia. We manage local recruitment, briefing, and on-site coordination in all three markets — ensuring consistent congress staffing standards regardless of venue location.

Markely’s delegate acquisition approach for scientific congresses starts with a thorough understanding of the target delegate profile — the clinical specialty, research discipline, professional sector, and geographic reach of the congress. We build campaigns that reach the relevant scientific community through a combination of digital advertising on specialist platforms, LinkedIn targeting by specialty and institution type, email marketing to relevant professional networks, and direct outreach to abstract authors and past delegate lists. Campaign strategy is adapted to the specific congress discipline rather than applied generically.

Markely provides PCO partner services for congresses across the UK, UAE, and Saudi Arabia. We support congresses at major venues including ExCeL London, NEC Birmingham, Olympia London, Edinburgh International Conference Centre, Dubai World Trade Centre, Abu Dhabi National Exhibition Centre (ADNEC), and the Riyadh Front Exhibition and Conference Center. For international congresses hosted beyond these markets, we can discuss support requirements on a case-by-case basis.
