What Cosalys consulting does

Cosalys Consulting is a French strategy, transformation, and organization consulting firm headquartered in Lyon, operating as part of the Aliantis accounting group. Incorporated in September 2024 with a share capital of €10,000 and a team of 1-10 employees, the firm targets small and mid-cap businesses (TPE, PME, ETI) across the Auvergne-Rhône-Alpes region. Its core service portfolio spans eight lines: Check-up 360° diagnostics, organizational structuring, strategy & development, co-piloting, HR advisory, cybersecurity, RSE (corporate social responsibility), and a structured training catalog.

The firm operates a human-delivered, project-based consulting model with custom pricing per engagement and a productized training arm offering individual programs priced from €1,200 to €12,000. There is no proprietary technology platform; the offering is built on senior consultant expertise across multi-disciplinary domains. Go-to-market is direct, supplemented by inbound through content marketing, webinars, and a recently launched web platform built in collaboration with Acteris, with co-branded referral dynamics from the Aliantis accounting ecosystem.

Cosalys is positioned as the dedicated advisory and transformation arm of the Aliantis group, extending cross-referral value from accounting, audit, and tax practices into strategic mandates. The firm has signaled vertical expansion into regulated professional segments (notably Commissaires de justice) and is investing in member-based content and event marketing to build brand presence in a competitive regional advisory market. No external funding, acquisitions, or revenue disclosures are present in the available data.

Expansion highlights5 records

Broad incumbents

• Wavestone: Wavestone is a leading French-origin consulting firm offering strategy, transformation, and innovation services. Comparable in service offerings (strategy, organization, cybersecurity) but at much larger scale and serving larger enterprises than Cosalys' TPE/PME/ETI target.
• Deloitte France: Deloitte France provides consulting, audit, and advisory services including strategy, HR, cybersecurity, and sustainability work that overlaps with Cosalys' full service portfolio. Operates at much greater scale and serves clients across all size tiers including SMEs.
• Sia Partners: Sia Partners is a global management consulting firm with deep French roots, covering strategy, transformation, and operational excellence. Overlaps with Cosalys across multiple service lines but serves a broader and larger client base.
• Roland Berger: Roland Berger is a global strategy consulting firm with a substantial French practice. Comparable in strategic and organizational transformation work, though its target market skews to large corporates rather than the SME segment Cosalys addresses.

Direct peers

• PMP Strategy: PMP Strategy is a French strategy consulting boutique that serves corporate and mid-market clients on strategic, organizational, and transformation topics. Comparable to Cosalys in advisory focus and French mid-market orientation, though PMP operates at larger scale.
• Kea & Partners: Kea & Partners is a French strategy and transformation boutique consulting firm serving mid-market companies with similar positioning to Cosalys — combining strategy, organization, and transformation work. Both target the under-served French mid-market with bespoke senior-led engagements.
• Argain Consulting: Argain is a French management and organization consulting firm serving SMEs and mid-cap companies with strategy, HR, and transformation work. Highly comparable to Cosalys in target customer (French PME/ETI), service mix, and regional French focus.

Regional players

• Aliantis: Aliantis is the parent accounting and expertise firm that incubated Cosalys, serving the same Auvergne-Rhône-Alpes SME client base with complementary (accounting, tax) services. It is the closest direct peer in client overlap and regional presence, though its primary offering is accounting rather than strategy consulting.
