Corporate event design & planning

Corporate events, designed, planned and run by one person.

I'm Helena. I design and plan corporate events, and I can run them on the day myself, so you deal with me from the first brief to the last guest.

Product launches, summits, leadership events and company days out, across London and surrounding areas.

Helena, founder of Oneva Events
About

Hi — I'm the person you'll actually be working with.

I started Oneva after years of walking out of events feeling something rare — that mix of energy and clarity you only get when every detail has actually landed. I wanted to design that feeling on purpose, not leave it to chance.

I handle the design, the planning, and — if you'd like — the room on the day myself, so the person who designs your event is the same one making sure it goes to plan.

Based in London, covering events across London and surrounding areas, and happy to talk through your event before you commit to anything.

What I organise

The events I plan and design.

01

Product launches

Launch events that put the product centre stage — from venue and staging through to the run of the day itself.

02

Summits & conferences

Multi-session programs with speakers, breakouts, and timings — planned so the day holds together end to end.

03

Leadership events

Offsites, board meetings, and executive gatherings where the details need to be right and the tone needs to be right too.

04

Company days out & parties

Team celebrations, socials, and away days — organised properly so you can actually enjoy them too.

Design and planning are quoted per project. On-the-day coordination and attendance is available for an additional fee — details on request.

How it works

Four steps, no handoffs.

I design your event and can be there to run it on the day — for an additional fee.

Step 01

Brief

We talk through what the event needs to achieve and who it's for.

Step 02

Plan

Venue, layout, and a full running order, agreed with you before anything is booked.

Step 03

Book

Suppliers confirmed, logistics sorted. One point of contact throughout.

Step 04

Event day

If I'm booked to attend, I'm on site running things so you don't have to.
