Every detail handled.
Every event delivered.
From international conferences to multi-day congresses — we manage the full complexity so your team doesn't have to.
Six ways we make events work.
Conference & Congress Management
Full-cycle management for conferences, congresses, and professional events across any sector — medical, tech, corporate, academic, and beyond. We handle programme coordination, speaker logistics, and everything in between.
Explore →Accommodation & Group Logistics
Negotiated room blocks, hotel contracting, and group travel logistics for delegations of any size. Room rates are inclusive of taxes; optional add-ons include breakfast, airport transfers, porterage, and airfare. All terms confirmed in a signed housing agreement.
Explore →Registration & Delegate Management
End-to-end delegate management — from registration system setup and confirmation flows to on-site check-in, badge printing, and post-event reporting. Your attendees get a smooth experience from first click to final session.
Explore →Venue Sourcing & Supplier Management
We source, evaluate, and contract venues, AV suppliers, catering, and all event vendors across Europe. We know which suppliers deliver and which cut corners — and we negotiate on your behalf.
Explore →On-Site Event Support
Our team is on the ground for the full event duration. Logistics management, vendor coordination, delegate flow, and real-time problem solving — everything runs to plan because someone is watching every detail.
Explore →Event Page Design & Development
Custom event websites and registration pages built for your specific event. Clean design, mobile-ready, with integrated registration and all the information delegates need — from agenda to hotel options.
Explore →Your event. Our full attention.
We understand that every event is unique. Whether you're running a 50-person leadership retreat or a 2,000-delegate international congress, the complexity is real — and the margin for error is zero.
Orgventa was built to offer what the industry often lacks: a small, expert team that takes full ownership of your event from brief to close. We work directly with decision-makers. No account managers, no handoffs. The people you brief are the people on the ground.
Meet the founders
We're Marina and Ana — two professionals with backgrounds in conference operations, hospitality, and client management. Between us we've spent over a decade managing conferences and congresses across Europe, from medical summits to corporate leadership events.
Our combined expertise spans programme coordination and multi-stakeholder logistics, group accommodation contracting, and delegate travel for events with 500+ attendees across multiple European destinations. When you work with us, you work directly with the people making the decisions — no account managers, no handoffs.
Numbers that speak for themselves
We've managed events of every size for organisations across Europe. Our clients return because we deliver.
Real feedback from the teams we've worked with.
Orgventa made our annual conference feel effortless. They handled everything — we just showed up.
Working with a remote team was seamless. Better communication than some local agencies.
They anticipated problems before they happened. That's the kind of partner you want.
How we work.
Four clear stages, from first brief to final debrief — so you always know where your event stands.
A detailed briefing call to understand your event, your goals, your constraints, and what success looks like for you.
A full event plan covering every workstream — logistics, venues, suppliers, registration, on-site operations — with clear timelines and ownership at each step.
From first supplier contract to last delegate departure, we manage every moving part. You stay informed; we handle the details.
A well-run event, documented outcomes, and a post-event debrief. And if you need us again — we're already up to speed.
A production partner you can rely on.
We work as a white-label subcontractor for European event agencies and PCOs. If you have the client relationship and need a trusted team to handle execution — accommodation contracting, delegate management, on-site operations, or full-event production — we operate seamlessly behind the scenes.
Your brand. Your client. Our work.
We're experienced working within agency structures, meeting your deadlines, and maintaining full confidentiality throughout. If you're managing capacity peaks or entering a new market, let's talk.

How does working with you remotely work?↓
We're based in Belgrade and work with clients and agencies across Europe. We use structured project management, shared documentation, and regular video calls to keep everything transparent. You always know what's happening and what's next.
What types of events do you manage?↓
Conferences, congresses, seminars, workshops, hybrid events, corporate offsites, galas, and more — across medical, tech, corporate, academic, and any other sector. We don't say no to complexity.
Do you work with agencies as well as direct clients?↓
Yes. We work as a white-label subcontractor for event agencies and PCOs who need production capacity. We're experienced operating within agency structures with full confidentiality.
What's your typical planning timeline?↓
For a complex international conference, we recommend engaging us at least 6 months in advance. For smaller events, 6–8 weeks is often workable. We'll tell you honestly if the timeline is tight.
Do you handle hybrid events?↓
Yes. We manage on-site logistics alongside the digital delegate experience — platform coordination, streaming setup, and making sure both audiences get an equally seamless event.
