Pearl Lemon Events works as a professional congress organiser for scientific and medical congresses, managing abstracts, scientific programme logistics, delegate registration, exhibition and sponsor floors, and compliance-sensitive hospitality.
A congress is a procurement exercise before it is an event: scientific committee deadlines, abstract handling, sponsor and exhibition sales, and delegate registration all run for months before anyone enters the hall.
What a congress mandate covers
- Core PCO functions: registration, abstracts, scientific programme scheduling
- Exhibition floor plan, sponsor packages and exhibitor servicing
- Multi-room production, session recording and simultaneous interpretation
- Delegate housing, transfers, badging and on-site help desk
- Committee reporting, budget control and reconciliation
- Compliance documentation, insurance and risk assessments
How projects are sized
Costs follow scale and complexity. Tell us which band you're in and we'll come back with a written scope and a costed breakdown.
- National congress
- Single country, one venue, plenary plus breakouts and a small exhibition.
- International congress
- Multi-day, multi-language, full exhibition, sponsor programme and delegate housing.
- Rotating series
- Same congress in a new host city each cycle under one specification and framework.
Delivering at conference scale
We support corporate delegations and client programmes at major international conferences, including MIPIM, Cannes Lions, MWC Barcelona and Web Summit, alongside the conferences, congresses and summits we run end to end for clients.
Congress work is run against committee deadlines and a reconciled budget line, with registration, abstracts and exhibition managed under one contract rather than split across suppliers.
- Multi-country delivery
- One central team, local suppliers appointed and managed in each host city.
- End-to-end scope
- Production, AV, logistics, travel, delegate management and hospitality in one contract.
- On-site management
- Named event managers and technical crew on site from load-in through to derig.

Professional congress organiser services
Association and scientific congresses have requirements that a general event agency rarely handles: abstract submission and review, scientific committees, multi-track programmes, exhibition and sponsorship revenue, delegate registration at scale, and a budget that has to balance across registration income and sponsor commitments.
We act as the professional congress organiser (PCO) across those workstreams, working to the association board or organising committee.
Congress workstreams we cover
Committee support, timelines and secretariat
Abstract handling, review workflow and programme building
Speaker and faculty management, travel and honoraria
Registration, ticketing categories, invoicing and delegate communications
Exhibition floor plans, exhibitor liaison and sponsorship fulfilment
Multi-room production, session AV, recording and hybrid streaming
Budget management across registration, sponsorship and grant income
Running the congress on site
Registration and delegate flow
On-site check-in, badge printing, session scanning and a help desk staffed for the full opening hours, so queues do not form at peak arrival.
Book A CallParallel session management
Each room gets a technician and a session steward working to one master schedule, with speaker preview and content collection handled before sessions start.
Book A CallExhibition and sponsor delivery
Exhibitors get a single point of contact for build, deliveries and access, and every sponsor entitlement is tracked to completion and reported afterwards.
Book A CallFrequently Asked Questions
Everything teams usually ask before we start planning together.
The committee owns the science and the community. We own the operational and commercial delivery — registration, budget, suppliers, production, exhibition and on-site running — so volunteers are not doing it alongside their day jobs.
