OPERATIONAL BRIEF · JUNE 2026

A predictable stream
of new interior designers.

This document outlines an operational plan to put Nature Squared’s surfaces in front of high-end interior designers across the UK, US and Australia through cold email outreach — ~ 6 minutes read.

Before reading

What you’re about to see is a first approach, built ahead of our conversation to give you a concrete preview of how we work.

The prospects, signals, and projections shown here are hypotheses — we’ll refine everything together once the engagement begins.

The goal of this document is to help you visualize what a campaign could produce.

01 / YOUR ACTIVITY 01 — 08

We know your DNA.

Nature Squared is a Swiss ethical design house, founded in 2000 by Paul Hoeve and Lay Koon Tan. For 25 years, you have turned natural materials most people discard — eggshell, seashell, feather, horn, bark — into bespoke luxury surfaces, handmade in your Cebu workshops with a team of 180+ artisans, material scientists and engineers. ISO 9001 / 14001 / 45001 certified and a UN Global Compact signatory, you are the only supplier of IMO-compliant natural materials to the superyacht industry. Your surfaces sit inside Rolls-Royce, Montblanc and Dornbracht pieces.

What sets you apart

Nature Squared makes luxury out of what others throw away. Eggshell, seashell, feather and horn become one-of-a-kind surfaces, each one unrepeatable because the material is. That story is rare, and it is backed by real craft : heritage skills in inlay, weaving and casting, preserved and scaled in your own workshops. You are not one finish among many ; you are a material nobody else can offer.

What we’ll pitch on your behalf

What we will pitch for Nature Squared in outreach : getting your surfaces in front of high-end interior designers — the people who specify materials for UHNW residences, boutique hotels and yachts. We introduce Nature Squared, point each designer to a project where your surfaces would fit, and offer a sample they can hold in their hands. The aim is a steady flow of designers who know your name and want to handle the material.

02 / YOUR MARKET 02 — 08

A market identified and qualified.

To size the market for Nature Squared, we focused on high-end interior designers across the UK, the US and Australia — the studios that specify natural, crafted, sustainable surfaces for residential, hospitality and yacht projects. You already hold a database of around 30,000 such designers, built together with Hugo at Bosco London, of which about half come with a usable professional email. The estimates below apply the Cold is Gold method to that base.

How we build this database

You already hold a base of around 30,000 interior designers across the UK, US and Australia, built together with Hugo at Bosco London. We qualify each one against the profile that fits Nature Squared (high-end residential, hospitality or yacht work, a natural and crafted aesthetic) and enrich it with AI : identifying the named decision-maker, validating the professional email, confirming the studio is active. Impossible to do by hand across tens of thousands of rows — that is what makes qualification at scale possible.

Why 50% contactable

Of the ~30,000 designers identified, only about half come with a usable professional email. Studios often sit behind a generic studio@ inbox, so reaching the named decision-maker takes enrichment. This 50% ratio is deliberately conservative, to give you realistic projections, not optimistic ones.

This market is presented as an example to help you visualize the opportunity. We can run the same analysis on any segment or geography you wish to target — for instance yacht and hospitality specifiers only, or markets beyond these three.
03 / PROSPECT SAMPLE 03 — 08

10 designers identified by our AI.

Before launching the campaign across the full list, our AI identifies a sample of 10 real designers that match the target profile. For each studio, it detects an actionable signal : the materials they favour, the projects they take on, a recent recognition. These signals form the basis for personalizing each email sent on your behalf. This sample is representative of the quality you will find across your full database.

For each prospect, our AI identifies a concrete signal: a named project, an award, a press feature. This signal justifies why to reach out now and forms the basis for email personalization.

This sample is a preview of what your full database will look like. You will have the opportunity to review it and guide us before the campaign launches.

WHY THIS PROSPECT FOR NATURE SQUARED

A palette of figured stone, oak, plaster and bespoke artisan pieces shows exactly the natural-material, craft-forward sensibility Nature Squared’s eggshell, shell and horn inlays slot into.

04 / AI PERSONALIZATION 04 — 08

Emails that feel handwritten.

A prospecting email that gets a reply is not a flattering email : it’s an email that proves we did our homework. The designer who receives it should think « this person looked at my work » before even reading the pitch. To get there, each personalized sentence cites a specific, verifiable fact, using the designer’s own vocabulary, not ours. For Nature Squared, we use three types of signals that are present across your target prospects.

The principle: when the prospect reads the email, they should think « this person researched me », not « this is a robot ». Each sentence cites a specific, verifiable fact using the prospect’s own vocabulary.

Here are the 3 types of signals we would use to personalize each email sent on your behalf.

01

Phase 6

Ongoing
Good to know: phases 2, 3, and 4 run in parallel with the technical setup (phase 1). Concretely, during the 1-month technical warm-up, we build your database and write your sequence — so the first emails go out as early as week 5.

Phase 1 — Technical setup

Creation of dedicated sending domains, SPF/DKIM/DMARC configuration, email address setup and warm-up launch (1 month). No action required on your end.

Phase 2 — Workshop (1h)

A structured session to define the database structure together, set the email tone, and gather your case studies and differentiators. This phase runs in parallel with phase 1 (Technical setup).

Phase 3 — Email sequence writing

First draft written, reviewed and refined with you, then AI personalizations added (the signals shown above). We validate the full email content before moving on to the database.

Phase 4 — Database build

A prospect sample (like the 10 above) is built and submitted for your approval. Once validated, we build the full database with quality control: field verification, contact qualification.

Phase 5 — Campaign launch

Sends start as soon as the warm-up is complete. First results within the first week. Real-time tracking of key metrics: open rate, reply rate, opportunities generated.

Phase 6 — Reporting & optimization

Real-time reporting via our platform. Continuous adjustments and A/B testing on subject lines, opening sentences, and sequences. Regular monthly or quarterly check-ins based on results.

A FINAL WORD

This document is not a sales pitch. It is a projection built on the real numbers from our campaigns — the scenarios presented are not promises, they are averages observed across our clients.

Our method has been operational for several years. It works when the fundamentals are in place : a clearly identified market, a differentiated positioning, a measured close rate. Nature Squared has all three.

We believe we can build for you a steady flow of qualified conversations with high-end interior designers who specify natural materials, over the next 12 months — with metrics we track together, month by month.

Whenever you’d like to discuss this in concrete terms, we’re ready.
