Investment Memo: Paris Copropriété Rooftop Solar Software Platform

1. Market Context

Paris rooftop solar potential is massive – but adoption is slow

The bottleneck is transaction cost, not hardware cost

• Hardware commoditized – panels, inverters, batteries are 80% cheaper than a decade ago.
• Labor fragmented – thousands of local installers, no national brand dominates Paris residential market.
• Friction points:
  • Copropriété general‑assembly votes (requires 50%+ majority)
  • Heritage‑building permits (Architecte des Bâtiments de France – ABF)
  • Enedis grid‑connection applications (6–12‑month queue)
  • MaPrimeRénov'/CEE subsidy paperwork
  • Multi‑owner billing for auto‑consommation collective

No one owns the end‑to‑end software stack for Paris residential solar

The gap: Software that owns the customer and the data, turning installers into replaceable vendors.

2. The Problem

For the syndic (property manager)

• Manages 20–100 buildings, each with a resident board pushing for energy‑saving initiatives.
• No time to research solar viability, compare installers, draft AG motions.
• Feels pressure to “do something green” but paralyzed by complexity.
• Current process: manual outreach to 3 installers → conflicting quotes → 12‑month back‑and‑forth → project stalls.

For the conseil syndical (resident board)

• Wants lower common‑charges (charges) and building‑level energy independence.
• Overwhelmed by technical/regulatory jargon.
• Needs a clear, vote‑ready proposal to present to all co‑owners.
• Fears making a mistake that locks the building into a bad deal.

For the installer

• Spends 40% of sales time on paperwork, not installation.
• Cannot scale because each copropriété deal is a custom negotiation.
• No recurring revenue post‑installation – commodity hardware margins shrinking.
• Reviews suffer because customers blame installer for Enedis delays / ABF rejections.

Outcome: Viable rooftops sit idle, solar adoption crawls, and everyone loses.

3. The Unit Economics

For the copropriété (end‑customer)

Scenario: 50‑unit Paris copropriété with 200 m² usable roof area

Assumptions: 20 kWp installation, 18,000 kWh/year production, 50% self‑consumption, current electricity price €0.22/kWh, feed‑in tariff €0.10/kWh. Subsidy values are one‑time but improve payback.

Installation cost: €25,000–40,000 (after subsidies). Payback: 4–7 years.

For the syndic (software customer)

Pricing model:

• Free: rooftop audit (data/lead‑gen)
• €800–1,500 per building: AG package + quote management (one‑time)
• 5–10% of installation value: full project management (optional)

Syndic economics:

• Manages 40 buildings → identifies 12 solar‑ready via free audit.
• Charges each building €1,200 for AG package + quote management = €14,400 revenue.
• Outsources headache, looks proactive to residents.
• Our cut: €800–1,200 per building (white‑label SaaS fee) = €9,600–14,400.

For us (software provider)

Revenue streams:

1. SaaS fee per building (syndic white‑label): €800–1,500 one‑time.
2. Commission on installation (if we manage project): 5–10% of €25,000–40,000 = €1,250–4,000 per building.
3. Recurring VPP/arbitrage (long‑term): €5–15/building/month once 1,000+ rooftops under management.

Scalability: One salesperson can onboard 2–3 syndics/month → 30–50 buildings/month. At €1,000/building → €30,000–50,000 monthly revenue within 6–12 months.

4. Competitive Landscape

No one offers a white‑label software suite that syndics can use to audit, propose, vote, and manage solar installations across their portfolio.

Adjacent funded startups (EU): None targeting the syndic/copropriété channel. Most solar‑software funding goes to utility‑scale optimization or residential monitoring.

5. Risks

6. Proposed Validation Plan

7. Go-To-Market

Buyer Persona: “Marie”

Role: Gérante of a syndic company in Paris (10–50 employees, manages 40–150 buildings)

• Background: Legal/admin focused, not technical. Under pressure from resident boards to lower energy costs.
• Her day: AG meetings morning, contractor calls afternoon, emails evening. No time for solar research.
• Pain point: Wants to offer “green” service to differentiate but fears taking on extra work.

The pitch (15‑minute meeting)

• “Marie, you manage 40 buildings. I can tell you exactly which 12 have solar‑ready roofs, what the payback is, and I’ll generate the AG documents for the ones you want to pursue. You look proactive to residents, I handle the legwork.”
• Show her a sample report for one of her buildings (pre‑populated using public data).
• “Cost: nothing for the audit. If you move forward, €1,200 per building for the full AG package + three comparable quotes.”

Sales Funnel

Acquisition Channels

Syndics don’t Google “syndic.” They discover tools through professional networks, associations, supplier referrals, and trade media. But they do Google the problems they’re trying to solve (reducing charges, navigating solar paperwork).

1. LinkedIn Sales Navigator (High‑touch)

• Target: “Gérant de syndic” / “Directeur de syndic” / “Syndic professionnel” in Paris region
• Message: “Vous gérez 40 copropriétés. Je peux vous dire lesquelles ont un toit solaire rentable et générer les documents d’AG en 48h. Démo gratuite?”
• Budget: €500/month for 100–150 targeted connections/week
• Expected response rate: 3–8% (syndics are active on LinkedIn for professional networking)

2. Google Ads (Intent‑based)

• Keywords:
  • Charge‑reduction: “réduction charges énergie copropriété”, “charges copropriété augmentation 2026”, “comment baisser les charges communes”
  • Regulatory updates: “nouvelle réglementation copropriété énergie”, “loi sobriété énergétique copropriété”, “ABF panneaux solaires Paris”
  • Solar‑specific: “installation panneaux solaires copropriété Paris”, “démarches panneaux solaires copropriété”, “AG vote panneaux solaires”
  • Subsidy paperwork: “MaPrimeRénov copropriété comment faire”, “CEE copropriété démarches”, “subventions panneaux solaires copropriété”
  • Energy‑sharing: “auto‑consommation collective copropriété”, “partage énergie copropriété”, “répartition électricité commune”
• Ad copy: “Étude gratuite : potentiel solaire de votre copropriété. Nous analysons gratuitement le toit de vos bâtiments et générons le rapport détaillé, les documents d’AG, et trois devis comparables. Réduisez les charges de 15 000 €/an sans vous prendre la tête.”
• Budget: €200 test (2 weeks); CPC estimated €2–6; volume low‑to‑moderate (50–200 searches/month in Paris region)
• Goal: 10+ audit sign‑ups; intent is high (they’re already looking for solutions)

3. Association Partnerships

• CNPI (Chambre Nationale des Professionnels Immobiliers) – sponsor a webinar “Copropriété solaire: réduire les charges sans se prendre la tête”
• FNAIM (Fédération Nationale de l’Immobilier) – advertise in their member newsletter
• UNIS (Union Nationale de la Propriété Immobilière) – exhibit at Salon de la Copropriété

4. Energy‑Audit Referrals

• Partners: Hellio, Effy, Ekwateur (they already audit copropriétés for energy savings)
• Deal: White‑label our rooftop‑scoring tool; they offer “solar potential audit” as an upsell
• Revenue share: 30–40% on AG‑package sales

5. Direct Outreach via Professional Directories

• Source: CNPI’s “Annuaire des syndics” (~2,000 registered professionals)
• Method: Personalised email + follow‑up call (“Nous avons analysé 3 bâtiments que vous gérez. Voici le potentiel solaire.”)
• Cost: ~€200 for directory access; 1–2 days/week for outreach

6. Trade‑Show Presence

• Salon de la Copropriété (Paris, Oct 2026) – booth cost ~€3,000
• BePositive (Lyon, Feb 2027) – energy‑transition focus, relevant for solar
• ROI: 50–100 qualified leads/event; 10–20 pilot conversions

7. Trade‑Publication Ads

• “Le Moniteur” – “Rénovation énergétique” section (syndics read for regulatory updates)
• “Immoweek” – property‑management focused
• “GreenUnivers” – green‑building audience
• Budget: €1,000–2,000/month for test campaign

Head‑to‑head test (Phase 1 validation)

Run both for 2 weeks, pick the winner as primary channel.

Why these channels work: Syndics are licensed professionals who maintain certification, attend association events, and rely on trusted suppliers. Google Ads capture intent‑based searches (they’re looking for solutions); LinkedIn/direct outreach create demand (they haven’t yet considered solar).

8. Sources & Verification Status

Most market‑size and adoption‑rate data comes from second‑hand research‑agent summaries. Primary verification needed.

9. Honest Assessment

What I’m confident about:

• Paris copropriétés are a large, underserved solar market.
• Transaction cost is the bottleneck — software can dramatically reduce it.
• Syndics are a motivated, reachable buyer persona.
• No incumbent owns the software stack end‑to‑end.

What I’m NOT confident about:

• Exact rooftop‑scoring accuracy with public data (needs LIDAR/ aerial for precise shading).
• Syndic willingness to pay €800–1,500 per building (needs pricing test).
• Installer cooperation on commission structure (needs partner interviews).
• Regulatory‑hurdle magnitude (ABF/PLU/Enedis timelines).

What would kill this thesis:

• Paris city hall launches a free, automated solar‑audit platform for all copropriétés.
• Syndics prove completely unwilling to spend time/ money on solar initiatives.
• Installers refuse to pay commission, making the marketplace untenable.

Bottom line

The pain is real, the buyer identifiable, the software wedge clear. The next step is a €500 demand test to see if syndics actually click “free audit” and engage. If 20+ sign up in two weeks, the thesis is worth 3 months of building.
