Timeline Canal in green · Lamarck in brown
The two clubs, side by side
| Canal · Paris 10th | Lamarck · Paris 18th | |
|---|---|---|
| Venue | 25 rue Yves Toudic. Former hot-air-balloon factory, then SNCF workshop, then Luc Besson studios. An 18 m glass roof and 400 m² atrium. | 74 rue Joseph-de-Maistre. Former printworks, renovated by Vincent Eschalier. A 150 m² terrace. |
| Floor area | ~2 000 m² | ~1,800 m² of fitness space + café + 300 m² flexible workspace (32 desks) |
| Facilities | Strength and cardio, yoga/dance studio, cycling, boxing/training, personal coaching, two massage rooms, sauna & steam room, coworking, library, Rond restaurant and bar. | Boxing/functional training, dedicated Hyrox room, low-impact classes, cardio and strength across two floors, saunas/steam rooms, herbal tea lounge, audiophile café (Hark), exhibition/DJ space. |
| Pricing | €195/month (two-month commitment) · €2,150/year · €35 trial. In 2018: €1,800–1,880/year, €1,450 for under-26s. | Same pricing + €30 fitness/coworking day pass · €129 weekly pass. |
| Members · September 2026 | 3,000 members (figure supplied by Remi). Historical: 700 after three months → 1,500 after 14 months. The early reported cap of 1,500–1,800 is not current capacity. Historical profile: 50/50 men/women, average age 35 (17–70). | 1,200 members (figure supplied by Remi). |
| Team | 12 employees + ~40 freelance coaches (2019); 20–49 employee band (2022). | ~60 coaches across the group (2025). |
| Funding | ~€3m from angel investors / family offices (Upward, Financière des Abondances, Jeanval, Mavilo, Vizono). No VC. | Dedicated SPV; LFR Holding 2 & 5 (Laurent Ritter, very likely the Voodoo cofounder) + Newscope Développement. The founders' holding company (Balise) serves as president. |
| Revenue ESTIMATE | 2019 memberships ≈ €2.4m (historical estimate). The previous 2026 estimate used the outdated 1,500–1,800 member range and has been withdrawn. Current revenue is not disclosed; member counts alone do not establish realised revenue. Accounts not published. | Same structure. Coworking and the café are open to non-members, filling daytime hours. |
| Membership density · September 2026 | 3,000 ÷ ~2,000 m² ≈ 1.50 members/m² of total club area. | 1,200 ÷ ~1,800 m² ≈ 0.67 members/m² of fitness space; café and flexible workspace excluded. Different area basis from Canal. |
Who they targeted
Canal Saint-Martin · 10th
84,000 residents, ~31,000 residents/km² (fourth-densest arrondissement). Ages 25–49 = 46% (+7 points vs Paris). 54% managers and professionals among employed residents. 54% single-person households.
Median income below the Paris average (~€26k vs €27.4k), poverty rate 17%. A young, dense, professional and creative neighbourhood, with daytime visitors from Gare du Nord/Est and République.
Initial audience: local freelancers, independent workers and creatives. B2B came later.
Montmartre / Lamarck · 18th
183,000 residents (declining since 2017), 48% managers and professionals, 57% single-person households. A pronounced north/south divide.
The southern 18th (Abbesses, Lamarck-Caulaincourt, Jules-Joffrin) resembles the 10th/11th: professionals in their thirties, independent workers and remote workers. A village-like neighbourhood with limited premium provision.
Coworking and the café respond to post-Covid remote work, which was absent from the equation in 2018.
The shared member profile
Aged 30–40, professional or self-employed, single or a couple without children, interested in design and culture, exercising three to five times a week. Willing to pay €195 for a place that serves as office, café and gym instead of €40 for an anonymous gym. Price acts as a filter: it shapes the community.
The playbook
Start with the building
Both venues are heritage industrial buildings (factory, printworks) with height and light. The venue defines the brand and justifies the price. Neither is a new-build ground-floor unit.
Dense, young, professional, underserved
Not necessarily wealthy by median income. ~200,000 residents within 1.5 km is enough if the target audience is concentrated there. The model needs concentration.
One price, a growing membership base
No budget tier. Canal reached 1,500 members after ~14 months and has 3,000 as of September 2026; Lamarck has 1,200 (figures supplied by Remi). The early 1,500–1,800 cap is historical. Prices rose 15–20% over seven years without adding a cheaper offer.
The social club supports the gym
Restaurant, coworking, private hire (400 m² atrium, 150 m² studios) and events: the venue operates from 7 am to 11 pm and stays visible to non-members.
Programming over machines
Distinctive classes unavailable elsewhere (Ropes Any Style, instability training, handstands, hip-hop yoga, Hyrox). People provide the differentiation.
One SPV per club, angel funding
No VC. ~€3m for 2,000 m² in 2018; different investors for Lamarck. Slow expansion: one club every seven years, rather than five in five years.
Implications for Movement (Marseille)
Density. September 2026 membership implies ~1.50 members/m² at Canal (3,000 over ~2,000 m² of total club area) and ~0.67 at Lamarck (1,200 over ~1,800 m² of fitness space, excluding café and flexible workspace). These area bases differ, and membership density does not measure simultaneous attendance or maximum capacity. The historical v1 model assumed 1.1 members/m² over 800 m²; the new figures do not change the Movement model. A social club still needs room for an atrium, café and coworking alongside its fitness space.
Capex. ~€1,500/m² all-in there vs ~€1,900/m² excluding working capital in v1: consistent with renovating an industrial shell, to be checked against a Marseille site (Euromed, southern Prado).
Pricing. €195/month is at the upper end in Paris; €149/month in Marseille is consistent in relative terms. Target a dense professional neighbourhood (6th/7th/8th), not necessarily the wealthiest.
Questions for founders and coaches: annual churn, non-membership revenue share, actual Canal vs Lamarck construction costs, attendance by time slot, and coworking's role in member acquisition at Lamarck.
Group structure in 2026 reconstructed from the company register
Balise SARL
Personal holding company of Basile Lombard-Latune. Share capital 2 407 673 € . A non-round amount, typical of an in-kind share contribution. 2024 revenue: €272k (management fees), profit €68.5k. President of LMG, MGF18, Newscope and LMG Work 1; managing director of RB2L since Jan. 2024.
Ruben Bertrand
President of RB2L since 2017; managing director of LMG, Newscope and LMG Work 1. No personal holding company visible in the register. He probably holds his shares directly.
2018 investors
Mavilo, Jeanval, Vizono, Financière des Abondances, Upward. RB2L shareholders, very likely moved into LMG through the 2023 contribution.
LMG — La Montgolfière Groupe
Parent holding company, registered purpose: acquiring and holding equity interests. Share capital €100 → €7,200,091 on 3 Nov. 2023. President: Balise SARL; managing director: Ruben Bertrand. Registered trademarks: LMG, LMG Social Sports Club, La Montgolfière Social Sports Club. Also president of MGF Formation (incorporated 6 June 2026, professional training in sport & wellness).
RB2L — La Montgolfière Canal
Club 1 operating company. Share capital €100k → €250k (May 2018). 20–49 employees (2022). Accounts filed with a confidentiality declaration from 2018. Covid fixed-cost support: 126,199 + 130,647 + 129,337 = 386 183 € (2021). Banque Populaire Rives de Paris appears in the 2018 filings.
MGF18 — La Montgolfière Lamarck
Club 2 SPV. Share capital €102 → €143 (8 Nov. 2024) with investment from LFR Holding 2 & 5 (Laurent Ritter) and Newscope Développement. Ruben Bertrand was managing director until 8 Nov. 2024, then Balise remained as sole president. The establishment at 74 rue Joseph-de-Maistre has been active since 1 Nov. 2025.
Newscope Développement
Registered purpose: development and operation of property complexes for sport, wellness and events. The founders' property/development vehicle: a shareholder of MGF18 and LMG Work 1. Separates site development from operations.
LMG Work 1 — LMG Monceau
Operates the Capital 8 B2B club (32 rue de Monceau, active since 7 April 2025). Sole shareholder: Newscope. The “1” suggests a series of corporate clubs.
Round 1 · Canal, 2017–2018
What the filings say
10 July 2017 : incorporation, €100,000 share capital, registered office in a 15th-arrondissement flat (42 rue de Cronstadt). The founders start before securing the venue.
15 May 2018 : share capital raised to €250,000, registered office moved to rue Yves Toudic, articles amended (shareholder agreement, governance). The round closes.
23 Oct. 2018 : trading name changed to La Montgolfière, one week after opening.
2018 filings : name the five holdings and Banque Populaire Rives de Paris. No convertible bonds, share warrants or pledges mentioned in public summaries.
Understanding the €3m
Share capital increased by only €150k. The announced €3m therefore spans share premiums (angels pay well above nominal value), shareholder loans and bank debt (Banque Populaire).
Assumed structure: €1.2–1.8m in equity + shareholder loans from angels, €0.8–1.5m bank loan secured against the business and guarantees, with founders providing the initial share capital. Across 2,000 m², ~€1,500/m² all-in.
Estimated split, not published. The €386k Covid support over nine months of closure (fixed-cost scheme, covering 90% of uncovered fixed costs) suggests ~€45–50k/month of fixed costs net of other support.
Round 1 investors who is behind each holding company
| Holding | Backers | Profile | Financial resources |
|---|---|---|---|
| Mavilo | Leveillé-Nizerolle family (Thierry, Sylvaine, Marin) · Boulogne | Business-advisory SAS, incorporated 2005, €502k share capital. Property (SCI, Maison Haussmann, 13 Molière), forestry investment group. | Equity €6.7m, net profit €2.3m (2022), cash €2.2m. The largest financial resources in the round. |
| Jeanval | Jean Berger de la Villardière — avenue Hoche, 8e | Financial and property holding company, incorporated 2005, ~71 connected companies (SCI, Valimmo…). A property investor, consistent with the building-led thesis. | Equity €6m, financial debt €12.2m, revenue €960k (2024). |
| Vizono | De Moustier family (Philippe, Enzo) · Villedieu, Vaucluse | Furnished-rental SAS, incorporated 2008. Also a shareholder in Lovenpar. | Capital €3.8m, equity €2.4m (2016). |
| Financière des Abondances | Catherine Rousselet — Boulogne | Fund-management SARL, incorporated 2000. Small family office with multiple holdings: restaurants (Houblon & Cie, Vert & Cie), cinema (Movie Sphere), property. | Equity €411k, revenue €129k (2025). Modest ticket. |
| Upward | Olivier Lebel (+ M.-H. Allemandou, P. Nudant) — 5e | Consulting SARL, incorporated 1996. Also invests in Genexpath, Inalve, Ideel Garden and Conquest Venture: an active seed-stage angel. | Equity €421k, cash €426k (2015). |
| Banque Populaire Rives de Paris | Bank | Named in the 2018 filings: business loan with conventional security (business pledge, guarantees). | — |
Interpretation: five private investors, all Parisian families or entrepreneurs aged 55–65 at the time, including two property profiles. No funds. Network-based investments (finance and family connections on the Lombard-Latune side; a Vincent Lombard-Latune works at the club).
2023 · The holding company and implied valuation
The sequence
8 Feb. 2023 : Basile incorporates Balise SARL, share capital 2 407 673 €.
20 July 2023 : LMG (€100) and Newscope Développement (€1,000) incorporated on the same day, at the same address.
3 Nov. 2023 : LMG share capital raised to 7 200 091 €.
1 Jan. 2024 : Balise replaces Basile as RB2L managing director; RB2L articles revised on 26 Feb. 2024.
What this implies
A €7.2m capital increase in a non-operating holding company, for a non-round amount, is interpreted here as a share contribution : RB2L shareholders exchanged their shares for LMG shares. The contribution value, ~€7.2m for 100% of RB2L, values the club five years after opening at roughly 2× membership revenue, ~€3,500/m².
If Balise holds only Basile's RB2L shares, his stake is worth €2.41m, or ~33 %. By symmetry, Ruben would hold around 25–33%, and the five holdings ~35–40 % combined.
Hypothesis: beneficial ownership is not public. This type of share contribution followed by a sale is also a common tax-deferral structure (Article 150-0 B ter), ahead of a partial exit or group-level fundraise.
Round 2 · Lamarck, 2024
The filings
17 July 2024 : MGF18 incorporated with €102 share capital (funds deposited 25 July, BODACC notice 7 August). President: Balise; managing director: Ruben.
8 Nov. 2024 : share capital increased to 143 € and management changed (Ruben steps down). LFR Holding 2 and LFR Holding 5 join (Laurent Ritter, born March 1986, five LFR holdings incorporated in 2017–2018 in the 12th arrondissement, consistent with the Voodoo cofounder after the 2018 Goldman Sachs deal), alongside Newscope Développement.
1 Nov. 2025 : the rue Joseph-de-Maistre establishment opens.
The structure
Moving from 102 to 143 shares at €1 nominal value means ~29% of the capital was issued to incoming investors, with actual funding held in share premiums and probably shareholder loans or bonds. The founders (through Balise + Newscope) retain ~71 % and the presidency.
Amount undisclosed. For 1,800 m² of fitness space + café + flexible workspace in a renovated printworks, the likely budget is €3–5m (2025 construction costs ≈ €1,500–2,000/m²), financed by a lead investor, the holding company and SPV-level debt.
The difference from 2018: one lead investor instead of five, one SPV per site to isolate risk, and no group-level dilution. A restaurant and hotel financing model.
A roadmap for Movement
Club 1: restaurant-style financing. An operating company with €100–250k share capital, four to six local private investors (families, entrepreneurs, one or two property profiles) contributing €200–500k each through share premiums and shareholder loans, and a bank loan covering around 40%, secured against the business. No VC: the model lacks startup-style growth and exits.
Target investors who value the building. Two of the five 2018 angels are property investors. In Marseille, target property families and local entrepreneurs rather than tech angels.
Plan the holding company from the start. Basile took five years to build the structure (Balise → LMG → Newscope). Establishing the founders' holding and separating property development from operations before club 1 avoids a later share contribution.
The five-year valuation (~2× revenue, ~€3,500/m²) is the reference for the shareholder agreement: it frames potential angel exits and acceptable dilution.
The closure buffer. A closed 2,000 m² club incurs ~€45–50k/month in uncovered fixed costs. Size cash reserves for six months of closure, including construction delays or damage, even without a pandemic.
Investor profiles (added 9 September 2026)
Mavilo · Leveillé-Nizerolle family.
Source of wealth: Laboratoire Dermatologique ACM (Clichy, founded 2000, pharmacy skincare: Noviderm, Sébionex, Duolys; revenue €21m in 2021 → €31.9m in 2024, net profit €1.8m, 43 employees). Thierry (1960) is a former ACM executive; Mavilo (2005) recorded €2.3m profit in 2022 (dividends/disposal). Related interests: Novomedis, Noble Suites, 13 Molière, forestry investment group. Sylvaine (1960) and Marin (1995) are Mavilo managing directors. Interpretation: a health/beauty entrepreneur diversifying into lifestyle, with a son of the founders' generation.
Jeanval · Jean Berger de la Villardière (1960).
Property development and investment: ~19 companies (Jeanval €6m equity / €12.2m debt, Valimmo, Matimmo Capital, Matiris, SCI Saint-Placide, rue de Vienne, LV Lafrette, Le Pool civil engineering). Former management roles at AREP (pilgrimage tour operator, Boulogne, revenue €18–22m) and Duquesne Service. Children Matthieu and Iris manage Valimmo; DLV Patrimoine became Jeanval managing director in 2025. Interpretation: sees the project as a property transaction (2,000 m² industrial building + funded tenant-operator).
Vizono · Philippe-Édouard de Moustier (1958).
Hotel property: president of SIPM (2 rue Lord Byron, Paris 8th, since 2009; hotel/restaurant acquisitions; holds Invest Hotels Nord 91, Metz Vannes Hendaye Invest Hotels, Hôtel Artea, Phibe). Member of Claranor's supervisory board (Avignon). Vizono is a family furnished-rental business (€3.8m share capital, Villedieu 84); Enzo (1998) is deputy managing director. Interpretation: sees a hospitality asset (F&B, events, recurring members) in a distinctive building.
Financière des Abondances · Rousselet family (Boulogne).
Family wealth; fund-management SARL (2000), managed by Alain Rousselet until 2014, then Catherine Rousselet, née Herrmann (1943); Antoine Rousselet works there. €8k share capital, €411k equity, two employees, ~€130–165k/year investment income. Previous investments: Vert & Cie, Houblon & Cie (bars/restaurants, 2001–2007), Movie Sphere (cinema), Caracterre, Immobilière du Bourgage (2020). Interpretation: a small venue investment by a family office backing places the family uses.
Upward · Olivier Lebel (1960).
Executive career + holding company: Upward (consulting, Paris 5th, 1996, ~€420k cash, no employees, consistent with an angel-investment vehicle; co-managers M.-H. Allemandou, P. Nudant), chairman of Equisecurite (Suresnes holding, €448k, EY-audited, deregistered 2019, linked to MDA Systèmes/Epicea), SCI Amaat. Seed portfolio: Genexpath, Inalve, Ideel Garden, Conquest Venture. The round's only portfolio angel. Interpretation: a bet on the team; probably organised the round.
LFR Holding · Laurent Ritter (1986), round 2.
Voodoo (cofounded 2013 with A. Yazdi; Goldman Sachs ~$200m in 2018, Tencent in 2020 at ~$1.4bn). Five LFR holdings incorporated Oct. 2017–Sept. 2018 (Paris 12th), coinciding with liquidity. Seed/pre-seed angel in gaming, esports and Web3, tickets 5–50k (Grâce, Sekai Studio, Aria, Flitter, MentorShow, Mansa). Lamarck sits outside that thesis: a local wealth investment, probably as a member. Interpretation: club 1 provides the proof.
Investor profile.
Round 1: four family fortunes aged 55–65 (skincare, property development, hotels, family office) + one career angel, all in Paris/Boulogne, three with children aged 20–30 in their holdings. Two think in property terms, one in hospitality: the building was the argument, fitness provided operational credibility through Ruben, and Basile translated the finance. Round 2: one liquid tech entrepreneur investing outside his thesis. Later funding comes from the member network.
For Marseille: Four to six local entrepreneurial families (health, property, hotels, trading) whose children fit the audience, plus one connector. Pitch the building and the asset. Tech angels can follow at club 2.
