Sidoun International

What Sidoun International does

Sidoun International, operating under the brand Sidoun Globe, is a Munich-based IT and services company that provides cost management and construction calculation software for the building industry. The firm's core offering centers on AVA software — the German construction workflow covering Ausschreibung (tendering), Vergabe (awarding), and Abrechnung (billing/settlement) — used by architects, planners, contractors, and public-sector clients to prepare, calculate, and manage construction cost data through standardized estimating and quantity-surveying processes.

The business is privately held and was founded in 1977, giving it more than four decades of operational history in a specialized regulatory and workflow niche within the German construction sector. The company operates with a small team of 11–50 employees, consistent with a focused, owner-operated software vendor serving the German-speaking Mittelstand rather than a scale-stage enterprise platform. Revenue mechanics are not disclosed in available source material; based on comparable niche German construction-software vendors, the model is presumed to combine perpetual or term-based software licenses with associated services (data updates, support, training).

Substantive extraction of product capabilities, pricing, customer segments, partnership network, and management team was not possible from the available data: the firm's website (sidoun.de) returned only a loading/verification message during scraping, and all structured firmographic arrays were returned empty. As a result, technical depth, go-to-market specifics, customer logos, and recent strategic activity cannot be verified from the current source set and represent a material data gap for any investment decision.

Direct peers

• Nevaris Build (Nemetschek): DACH-focused AVA and construction accounting software within the Nemetschek group. Head-to-head competitor for German contractors evaluating AVA solutions.
• Thinkproject: European construction and infrastructure platform (now combining Conject and former thinkproject assets) providing tendering, contract and billing modules comparable to AVA workflows.
• RIB Software: One of the leading German providers of construction software (iTWO platform) covering tendering, awarding and billing (AVA) workflows. Directly competes with Sidoun's AVA offering in the DACH market.
• California.pro: German construction ERP/software specialist focused on AVA, cost control and project accounting for mid-market contractors — direct overlap with Sidoun's core value proposition.
• Causeway Technologies: UK-based vendor of estimating, tendering and BIM-based cost management software for construction. Comparable product scope to Sidoun's AVA cost calculation and management offering.

Broad incumbents

• Schneider Electric (RIB MTWO): Owner of RIB MTWO, the integrated construction platform from RIB Software. Competes in the same tendering/awarding/billing workflow space as Sidoun from a much larger industrial-software position.
• Nemetschek Group (Allplan / Nevaris): European construction-software group whose Allplan and Nevaris brands cover AVA, BIM and cost management. Overlaps with Sidoun's cost management and AVA capabilities as part of a much broader portfolio.
• Autodesk Construction Cloud: Global incumbent offering BIM-based cost management and tendering capabilities (Autodesk Build, takeoff/estimating modules). Targets the same construction cost-control buyer as Sidoun but as part of a much larger platform.
• Trimble: Global construction technology provider with strong DACH presence (including former Plancal/Nevaris assets). Competes in cost estimation and AVA workflows as part of an end-to-end construction platform.

Regional players

• Soffice TOP: German provider of construction software including AVA and cost management modules, comparable in scope and regional focus to Sidoun's offering.
