Chapter I

Eva Sleipa, an opera­turned voice strategist rewriting how European keynote speakers are heard.

§ II — The Arc

From the wings of the Royal Opera to the rooms where decisions are actually made.

Eva Sleipa spent the first decade of her professional life inside a different kind of room. Trained in Oslo and Salzburg, she sang supporting roles at the Norwegian National Opera through her late twenties — long enough to learn what a body on stage can be made to do to a thousand strangers, and long enough to notice that almost none of that training ever left the building with the people who needed it.

In 2014 she founded a practice in a single rented room on Storgata with one quiet conviction: that the techniques opera singers use to project, pace, and hold a hall could be taught — rigorously, measurably — to founders, executives and TEDx applicants facing audiences ten times smaller and a hundred times more distracted. The early clients were Norwegian tech founders pitching Nordic VCs. The work spread, country by country, by word of mouth from boards and partner-track partners who had stopped losing the room in their first ninety seconds.

A decade later, the practice remains a closed-door operation — fourteen clients per quarter, no exceptions, every engagement built around the same premise: that a talk is a piece of architecture, and architecture can be engineered.

§ III — Credentials, in the margin

The training, named plainly.

Four entries a senior buyer expects to find before they enquire, written as marginalia rather than as marketing copy.

    Certificate in Voice & Performance Coaching, awarded 2010. The foundational pedagogical training.

  2. 02

    Certified Lessac practitioner, awarded 2016. One of the few European coaches holding dual certification across these two institutions.

  3. 03

§ IV — The Record

Outcomes, not adjectives.

380+

keynote speakers coached across 22 countries since 2014.

41%

average reduction in early-talk audience drop-off within the first ninety seconds, measured across coached clients.

2.7×

average increase in post-talk inbound leads reported by client speakers within sixty days of delivery.

92%

client rebooking rate maintained across six consecutive years of practice.

Numbers are drawn from the practice’s own client log, 2014–Q1 2024.

§ V — The Practice

A closed-door practice, by design.

Eva works with fourteen clients per quarter, and not fifteen. The cap is not a marketing gesture; it is the calendar’s honest answer to what the work actually demands.

Diagnostic sessions, intensive rehearsal weeks and post-talk reviews are scheduled long in advance, with deliberate buffer between engagements. As of last quarter the prospective-client list stands at forty-seven names — most of them referred by past clients, none of them converted by an aggressive funnel. Intake opens when it opens.

The effect, intended or not, is that the diagnostic conversation begins as a considered professional engagement rather than a coaching product. There is no tiered offer page, no packaged bundle, no upsell modal after the call. There is a ninety-minute diagnostic, a written read-out, and a recommendation: proceed, defer, or do not.

§ VI — Enquire

If the file is open, the diagnostic is ninety minutes long.

The diagnostic is a paid, ninety-minute working session — a recorded read-out of how your talk lands in its first ninety seconds, what is working in your delivery, and what is leaking attention. You leave with a written read-out and a clear recommendation. There is no follow-up sales call.

Current waitlist: 47 names. Estimated next opening: late Q2 2024.
