Venture design concept
How we turned a historic roastery's 320 partner bars into its zero-ad-spend acquisition channel
The strategic decision: validate the economic sustainability of a nationwide D2C coffee subscription model, while neutralising the channel-conflict risk with the 320 partner bars that carry the company's core revenue.
Venture design concept. Company anonymized; all figures are modeled scenario assumptions, not audited results.
Projected outcomes · modeled scenario
First-order acquisition cost (€2.42) against the stated digital CAC range (€35–50), computed conservatively on the low end of that range. Acquisition is not advertising: it is the 15% commission paid to the referring bar on the first order.
Recurring revenue share paid to partner bars on the subscriptions they generate. It is the commission rate, not a 15% uplift in the bar's turnover: no baseline bar turnover is stated, so the impact on its P&L is not verifiable.
€0 in paid ads (Meta/Google) — acquisition financed by the existing channel.
01 — Context
The illusion of an 85% gross margin
The second generation joined the family roastery with a categorical brief: “We need to launch a D2C specialty coffee subscription e-commerce to catch urban trends, bypass intermediaries, and take the 85% gross margin for ourselves”.
The assumed D2C list price is in fact €44–50/kg depending on the plan (€12.50 per 250 g = €50.00/kg; €22.00 per 500 g = €44.00/kg), versus €17/kg in the Ho.Re.Ca. channel: the coffee gross margin has to be recomputed on those prices, and it is not the 85% of the brief. The first phase of our work grounded that enthusiasm in the real unit economics of online advertising and the financial structure of an SME.
The real-margin matrix (historical Ho.Re.Ca. channel)
| Economic line item | Value (€/kg) | % of revenue |
|---|---|---|
| Ho.Re.Ca. sale price | €17.00 | 100.0% |
| Cost of goods sold (COGS) | €6.00 | 35.3% |
| Theoretical gross margin | €11.00 | 64.7% |
| B2B commercial-service burden (pro machines, maintenance, deferred payments) — stated parameter, not broken down by line | €8.50 | 50.0% |
| Real operating margin (EBIT) | €2.50 | 14.7% |
Act I — Analysis · Discovery
Dismantling the digital illusion to map reality
The market data from our quantitative research immediately reframed the project's perimeter:
- Ad costs on Meta and Google Ads to reach coffee buyers in Italy have doubled in the last 24 months (stated estimate, with no public source and no verifiable measurement window: parameter to be confirmed).
- A CAC in the €35–€50 range, combined with a real blended AOV of €16.15 (€840 of monthly revenue across the 52 subscribers of the 32 basic + 20 family mix) and a 14% churn rate (stated parameter, not attributed to a source), meant burning cash on every paid-acquired customer: at a 35% blended contribution (~€5.65 per order), recovering a €35 CAC takes more than six months of retention — beyond the average lifetime implied by 14% churn.
- Field interviews confirmed that using the main brand online would push baristas to cancel their commercial contracts for fear of unfair competition.
Four levers on two axes: production capacity vs. channel risk
Industrial Assets
Historic roasting lines underused in the afternoon windows. Specialty green-coffee lots already optioned at origin but previously diluted into commercial B2B blends for lack of a dedicated sales channel. Explicit constraint: with the dashboard mix each bar consumes 18 kg/month (32 × 0.25 + 20 × 0.50), i.e. 216 kg/year; 320 bars would require 69.1 t/year against the ~50 t residual (+38%). At unchanged capacity rollout saturates at ~231 bars (50,000 / 216): beyond that threshold additional capacity is required, an investment decision outside this Phase 0 perimeter.
Channel Friction & Risks
Field sales agents and historic bar owners perceive D2C e-commerce as unfair competition. The estimated risk is cancellation of core B2B supply contracts driven by perceived price cannibalisation.
Brand Architecture Shield
Isolating retail positioning. The main brand acts as an institutional quality guarantor, while aesthetics, packaging, formats (only 250 g whole beans and premium compostable capsules) and price (€44–50/kg depending on the plan) stay fully decoupled from the standard counter offer.
Ecosystem Incentive Alignment
Flipping the barista's role: from commercial blocker to zero-cost digital acquisition touchpoint. A physical kit with a unique QR code in the venue tracks conversions and pays passive commissions on every subscription renewal.
Create a new digital-native independent brand
While this option protected the core brand, it would have zeroed the value of the existing assets (plants, direct green-coffee supply chain, logistics). The roastery would have competed as just another startup on the single lever of ad spend, facing unsustainable barriers to entry.
Act II — Solution · Venture design
Turning the enemy into the biggest commercial ally
If open D2C was financial suicide, the answer was to invert the paradigm: turn the network of 320 partner bars into the primary customer-acquisition channel — at zero cost. We redesigned the venture architecture around a Phygital B2B2C model.
Target value proposition
Reach the bar customer who drinks quality coffee at home (smart working). The promise: “Your favourite roastery's coffee, roasted fresh on demand and vouched for by your trusted barista”.
Brand concept
Launch of the exclusive premium line “[Core Brand] Privé”, sold only as whole beans or high-end compostable capsules, entirely absent from mass distribution.
Business model (revenue share)
Every bar receives a physical display kit with a unique QR code. For every customer who subscribes by scanning that code, the barista earns a recurring 15% commission on every monthly renewal, for the full lifetime of the subscription.

The Phygital journey: from the bar counter to the customer's door
QR code scan
At the bar counter the user notices the premium Privé display and scans the QR code with their smartphone.
3-click checkout
They land on the mobile page, pick a consumption frequency and complete the subscription with zero friction.
Fresh coffee at home
Every month they receive freshly roasted specialty coffee, with a note that thanks the bar that referred them.
Physical counter display
A physical kit with sample packaging and a unique QR code tracked via a UTM tag dedicated to that venue.
D2C mobile platform
An ultra-lean web-app optimised for fast conversion, with format and frequency selection in a single linear flow.
Barista dashboard
A private panel where the owner sees active customers and accrued 15% commissions in real time.

The system reads the QR code ID and uniquely binds the subscribed user to the referring bar code.
Locked-in commission
The subscription persistently locks recurring revenue share on the attributor bar for the whole customer lifetime.
On-demand roasting order
Each renewal automatically generates a ticket in the lab, adding the required kg to the scheduled weekly roasting cycle.
Payment Gateway

Outcome & validation criteria
Go/No-Go thresholds set for a designed 15-bar pilot; projections modeled on comparable benchmarks
The expected effectiveness of the model was set ex-ante with Go/No-Go thresholds for a designed 8-week pilot across a cluster of 15 bars. The figures below are projections modeled on comparable benchmarks, not field measurements.
Owners who would actively pitch the subscription. Go threshold: > 70% · Modeled projection: 86%.
Scans converted into an active subscription. Go threshold: > 3% · Modeled projection: 4.2%.
Acquisition cost is the 15% commission on the first order: €1.88 on the basic plan (15% × 12.50) and €3.30 on the family plan (15% × 22.00). With the dashboard's 32/20 mix: (32 × €1.88 + 20 × €3.30) / 52 = €2.42 — −93% against the low end of the stated digital CAC range (€35–50). One declared, not-yet-quantified item: amortisation of the in-bar display kit, a real cost the document never estimated, to be confirmed.
In this modeled scenario the venture clears its Go thresholds, supporting a recommendation to run a live pilot before building the proprietary platform. The thesis survives the harder test: D2C contribution margin is ~35% blended (26% basic plan, 43% family plan), not the 60% of the brief, yet still more than double the 14.7% the roastery keeps in the Ho.Re.Ca. channel after commercial-service burden. Two explicit constraints: shipping is assumed at €5.00/order (stated parameter, to be confirmed with the carrier) and, at unchanged production capacity (~50 t/year), rollout saturates at ~231 bars — beyond that threshold additional capacity is required, an investment decision this case does not cover.
