What makes us different

Why brands choose to grow with us.

We are not a service provider. We are a strategic partner that gets involved in the business as if it were our own.

E-commerce specialisation
100% focused on online brands. All our knowledge, processes and people are built for digital commerce — we are not a generalist agency.
Performance + Creative
Our own 21Creatives methodology combines performance data with effective creative. The best ads are not the prettiest ones — they are the ones that sell.
International expansion
We scale brands into new markets profitably. Our clients go from selling in one country to generating revenue in more than 30.
Strategic partner
Real accompaniment, not just execution. We take part in the business strategy, review the numbers and make decisions geared to sustainable growth.
Case studies

Real results, real brands.

Each of these cases represents a different reality. The common thread: profitable, sustained growth.

Case 01 From local to international

A Spanish fashion brand selling almost exclusively domestically (98.4%). After one year with 21Nova, 35% of its revenue already comes from international markets.

Domestic: €247,749
International: €3,970
After 1 year

Case 02 From 8% to 45% international revenue

A brand established in 2014, strong in its home market but with only 8% international revenue and stalled acquisition. In 4 months it multiplied its international share by 5.6.

Case 03 LATAM e-commerce — Growth + Retention

A Latin American brand with a powerful connection to its audience, but with repeat purchase completely untapped. We combined aggressive acquisition with a retention strategy that turned one-off buyers into recurring customers.

Custom proposal

What we propose for Sundays.

Sundays is not a saturated brand — it is an unattended one. It grew +35% in 2025 and is down −51% year to date in 2026, which is exactly the period with no one steering it. That is a far better problem to have, because the fix is known. This proposal is built to run the full commercial engine for six months — not just the ad accounts.

Proposed plan · 6 months

Sundays × 21Nova
Relaunch Partnership

Initial contract
Sep 26 – Feb 27
Ad spend controlled by MER · Review at month 3
Four workstreams, one team
01 · 21Performance
Paid Media & Performance
Full acquisition engine. Meta and Google as the core, Pinterest and TikTok tested as the account earns them. Account structure rebuilt from zero, custom audiences off the historic buyer base, budget planned day by day and market by market, MER as the single control metric.
Standard 21Nova fee from £2,500 / month
02 · 21Creatives
Content Repurposing
Sundays already has an archive of brand content that has never been worked as performance creative. We turn existing assets, product shots and UGC into a continuous ad rotation: hooks, formats, statics, cut-downs and iterations driven by what the data says is working — without a new production budget.
Standard 21Nova fee £1,900 / month
03 · 21Retention
Email Marketing & Retention
The cheapest revenue in the account. Around 20–25K historic buyers and £1M of accumulated sales sitting in the database untouched. Full Klaviyo build: deliverability, segmentation, RFM, core flows, lead capture, campaign calendar and dashboards — live before we spend a pound on cold traffic.
Standard 21Nova fee from £2,000 / month
04 · 21Conversion
eCommerce Management & CRO
The store itself as a growth lever, not a passive endpoint. Range architecture and merchandising for the curated line-up, bundles and cross-category sets, free-shipping threshold work, PDP and checkout optimisation, tracking, and the mechanics designed to move the standing beanie stock while lifting AOV.
Standard 21Nova fee £2,000 – £2,500 / month
Initial duration
6 months (September 2026 – February 2027) — with a formal performance review at month 3 and the option to renew or extend at the end of the term.

Channels
Paid Social · Paid Search · Email & SMS · Organic support
UK first — break-even ROAS is around 1.6 there. US enters in phase two and only via a 3PL, where the customs base drops from retail price to landed cost. EU is deprioritised while the €3 flat duty and VAT stay as they are.
Ad spend
Paid directly by Sundays to the platforms and governed by MER, not by a fixed budget. Working target: MER around 30%, with a contractual ceiling at 35%. Blended ROAS 3 is the target — cold prospecting will run at 1.8–2.5 in the first weeks and 2.5–3.5 through November and December.
Included services
Everything required to run the four workstreams, including:
Monthly strategic meeting to align on objectives, needs and next steps.
Weekly meeting so you are 100% across everything happening in the account.
Monthly budget plan, broken down day by day, week by week and by channel.
A Growth Document built specifically for Sundays and kept continuously updated (all key metrics across all markets, historical series to forecast future investment, and so on).
Diagnostic, analysis and scoring of the 10 pillars following our proprietary methodology, 21Method™:
Initial Research covering value proposition, positioning vs the market, competitors, references and more.
Unit Economics exercise to guarantee optimal profitability in each market.
Creation and continuous updating of the 21Creatives Methodology document + best-references board.
Full Klaviyo setup and ongoing management: flows, campaign calendar, segmentation and RFM.
Store and range setup: merchandising, bundles, shipping thresholds and conversion work.
Monthly reporting across all channels in Looker Studio / Google Sheets.
Objective
Take Sundays from a £9K/month run-rate back to a profitable, scalable operation in six months.
£165,000 net sales over the 6 months in the base case — 1.86× the counterfactual of doing nothing.
Blended MER at or below 35% every month, as a contractual gate.
1.8 units per order through bundles, an £80 free-shipping threshold and cross-category sets.
Beanie stock sell-through as an explicit target, not a by-product — including the gifted-beanie mechanic on orders over £80, which at a £2.98 unit cost is the cheapest AOV lever in the business.
Database reactivation before cold spend — the ~20–25K historic buyers are the cheapest revenue available.
Fee model

Investment structure.

Four workstreams that would normally be priced separately, delivered for a fixed fee of £2,000 per month plus a variable that only triggers on the growth we actually create. If the brand does not grow, the variable is zero. All figures exclude VAT.

To start working together
One payment at the start of the contract — it covers every setup needed to have all four workstreams live from day one.
One-Time Opening Fee
£6,500
Single payment on signature. Three separate setups that would normally be quoted — and invoiced — independently.
Growth Audit + 21Method™ onboarding
Initial research, unit economics by market, account structure rebuild, tracking, 21Method™ 10-pillar diagnostic and all kick-off deliverables.
£3,000
Email marketing setup
Full Klaviyo build: audit, deliverability, segmentation, RFM segments, core flows, lead capture and dashboards on the ~20–25K historic buyer base.
£2,000
Store & CRO setup
Range architecture for the curated line-up, merchandising, bundles, shipping-threshold mechanics, PDP and checkout work, conversion baseline.
£1,500
Total payable on signing the contract £6,500
What this normally costs
The same four workstreams, priced at 21Nova's standard rates — and what Sundays actually pays.

Monthly reduction
−77%
£6,650 less per month than the standard rate card for the same scope.
Over the 6-month term
£39,900
Difference between £51,900 at standard rates and the £12,000 fixed component Sundays pays.
This is the trade the variable buys. We take the fixed fee down by 77% and put our upside on the same side of the table as yours: we only earn more if Sundays sells more. For our fee to reach the standard rate card, Sundays would need to be doing around £65,200 in net sales in a single month — roughly seven times the current run-rate. If that happens, neither of us will be arguing about the fee.
Monthly fee simulator
Move the slider to see what Sundays pays at any level of monthly net sales.

The fee has two parts. A fixed £2,000 per month, and a variable on net sales above £12,000 in that month. The variable rate depends on how efficiently we get there — if the account is not efficient, our rate halves, and if it is inefficient, we earn nothing on the growth at all.

Excluding VAT

Where the £12,000 threshold comes from

The threshold is not a round number picked in a meeting. It is what Sundays would be expected to do without paid media, given the trend the brand is already on.

Net sales are running −51% year on year. Applying that same decline to the six months we will actually be competing against — September 2025 to February 2026 — gives the baseline below.

Net sales, Sep 2025 – Feb 2026

Applying the current trend (× 0.49)
£72,381.36
Divided over 6 months
£12,063.56
Threshold applied
£12,000

For reference, running the same exercise across the full 2025 year (£273,580.73 net sales) gives a monthly average of £11,171. We have used the higher of the two figures, because September to February is the stronger half of the year and it would not be fair to charge a variable on revenue the season delivers on its own.

What protects you
MER gate
The 12.5% band only applies with blended MER below 35%. Between 35% and 50% our rate halves to 6.25%. At 50% or above we earn nothing on the growth. Our incentive and yours point the same way.
Growth 360°
We do everything needed to grow your eCommerce — apart from content generation and organic posting. No extra people to hire, no extra providers to manage and pay.
Variable only on growth
Nothing is charged on the first £12,000 of net sales each month. That revenue is yours whether we are here or not, so we do not invoice on it.
Review at month 3
A formal review at the end of November, tied to the restock decision. Both sides get a clean decision point before January and February.
Next steps

How do we get started?

The onboarding process takes an estimated three weeks and is designed to get us up and running on the strongest possible footing.

01
Confirmation and legal details
Confirm you want to go ahead and send us the full name and identity document of the legal representative signing the contract, along with the company's tax information.
02
Contract signature and opening fee payment
We will send you the services agreement. Until the contract is signed and the opening fee has been paid, we cannot kick off the onboarding.
03
Onboarding — 3 weeks
Once the contract is signed and the payment made, we start all integrations so we are operational as soon as possible.
Welcome Call — After signature we schedule a welcome call where we walk through the methodology, the first steps and complete a questionnaire with the key questions.
First strategic sessions — ~7 days after the Welcome Call. Three sessions: Business & Operations, eCommerce Growth & Performance and Creative Workshop. The 21Nova team prepares the initial study in parallel.
Content request — We request the preparation and delivery of the content needed to launch the advertising campaigns.
Growth Diagnostic Presentation — A full analysis of the business following our proprietary 21Method™: we assess the business across the 10 most important pillars (logistics, sourcing, internal hiring, and so on).
Initial strategy execution — While Sundays prepares the content, the 21Nova team works on the initial strategy for the campaign launch.
Estimated date for first campaigns: Second half of August / start of September.

Let's grow together,
Sundays.

Paid media, content, email and eCommerce management to bring Sundays back to profitable growth.

To move forward, email us at finance@21novastrategy.com letting us know you want to proceed, and we will send over the contract and the next steps.
