Cabinet Hayot Expertise in Paris: DNVB & e-commerce startups. Fundraising, investor reporting, Cash Conversion Cycle, BSPCE, JEI. Pennylane + n8n stack.
DNVB (Digitally Native Vertical Brand) — Sézane, Asphalte, Cabaïa, Respire, Le Slip Français, Typology. Hybrid model: vertical physical product + DTC (direct-to-consumer) + strong brand storytelling. Hybrid accounting: contribution margin per channel + SaaS-like metrics (CAC, LTV, MER) + e-commerce inventory BFR. Cabinet Hayot Expertise in Paris structures your accounting to go from seed to Series A without friction.
| Model | Stock | BFR | Key metrics | Typical margin |
|---|---|---|---|---|
| B2B SaaS | None | Negative (annual prepay) | MRR, ARR, NRR, churn | 70-90 % |
| Classic e-commerce | Physical | Positive | AOV, gross margin | 30-50 % |
| DNVB | Physical vertical | Positive (high) | CAC, LTV, MER, contribution margin | 50-70 % gross / 15-25 % net |
| Marketplace seller | Physical (FBA) | Positive (Amazon D+14) | TACoS, marketplace ROAS | 25-40 % net |
Cabinet Hayot Expertise computes for each DNVB: Contribution Margin per channel, MER (Marketing Efficiency Ratio), CAC Payback, LTV/CAC > 3 (health threshold), Repeat Rate, Cohort Retention 6/12/18 months.
CCC = DSO + DIO − DPO. For a DNVB:
Without CCC steering, a fast-growing DNVB starves on cash despite accounting profitability. Typical case: DNVB +60 % YoY with positive EBITDA but free-falling treasury (emergency fundraise needed).

Cabinet Hayot Expertise audits eligibility in first engagement. Typical savings EUR80-150k/year on social charges for a 5-10 person DNVB.
Structuring in 30-45 days: 3 years of detailed P&L per channel, cohort KPIs (CAC, LTV, retention, repeat rate), contribution margin per channel/product, CCC + 18-month cash projections, clean cap table (BSPCE, BSA, planned dilution), legal structure, significant customer/supplier contracts, IP, certifications.

A DNVB combines DSO ≈ 0 (immediate payment) + high DIO (60-180 days inventory) + variable DPO depending on supplier negotiation. Without CCC steering, a hypergrowth DNVB starves on cash despite positive accounting profitability. Cabinet Hayot Expertise typically reduces CCC by 30-40 days in first engagement via DPO negotiation + stock rotation optimisation = 1-3 months of runway gained.
