What SpiderPlus does
SpiderPlus & Co. is a Japanese construction technology company that provides SPIDER+, a cloud-based construction drawing and site management SaaS application. Originally launched in 2011 as an iPad-native app, SPIDER+ enables field supervisors at general contractors, specialty trade contractors (electrical, plumbing, HVAC, insulation), and plant operators to manage blueprints digitally, capture inspection photos, track construction progress, and generate reports, replacing paper-based workflows on Japanese construction sites. The platform is reported to reduce average on-site work time by approximately 2.5 hours per day. The company serves over 1,200 construction firms and approximately 49,000 users (end of 2021), with ARR of 2.18B JPY at that time and a stated target of 10B JPY by 2027.
The technology stack centers on an iOS/Swift mobile app with PHP/Ruby server-side backed by PostgreSQL, with integrations into NYK Systems' Rebro (BIM/MEP), MODE Inc.'s BizStack (IoT sensor data), and emerging connections through the Infomart TRADE platform. Recent AI features include the Reinforcement Inspection AI (computer vision on reinforcement bar photos), the Finishing Inspection Voice-Input AI (speech-to-text, co-developed with Konoike Construction), and S+BIM (in-field BIM viewer). The company maintains ISO/IEC 27001:2022 certification for information security.
SpiderPlus generates revenue primarily through monthly SaaS subscriptions (pricing not publicly disclosed, quote-based), supplemented by SPIDER+ BPO/BpaaS services (outsourced field data processing) and IoT/consulting services for plant maintenance. Distribution is dominated by direct enterprise field sales organized regionally in Japan, with partner channels through office equipment rental distributors and an expanding international partner network covering Southeast Asia (Vietnam, Malaysia, Philippines) and the Middle East (UAE, Qatar). Founded in 1997 as an insulation contractor, the company rebranded from Legolis Co. to SpiderPlus Co. in November 2020 and listed on the Tokyo Stock Exchange Mothers market in March 2021 as the first construction DX IPO.

SpiderPlus competitors and assessment
Company assessmentDirect peers
- ANDPAD: Japanese vertical SaaS platform serving the construction industry, covering project management, drawings, and field communication. ANDPAD is the most directly comparable domestic competitor to SPIDER+ in construction DX SaaS for Japanese general contractors and specialty trades.
- Buildertrend: Construction project management SaaS focused on residential and light-commercial builders, with scheduling, client communication, and field documentation. Direct peer in construction DX SaaS, though more skewed toward residential than SpiderPlus's commercial/industrial mix.
- Fieldwire: Field execution platform for construction crews offering task management, drawing markup, inspections, and punch lists. Direct competitor in mobile-first construction site management, though with stronger North American presence than SPIDER+.
- Procore Technologies: Global construction management SaaS platform offering project management, quality/safety, and field collaboration tools. Procore is the closest international competitor to SPIDER+ in construction site management SaaS, though it serves larger enterprise customers with broader feature scope.
- ダンドリワーク (Dandori Work): Japanese construction management SaaS focused on workflow digitization for specialty trade contractors. Direct domestic competitor in the construction DX SaaS space, particularly for smaller specialty contractors—a segment SPIDER+ also targets.
Broad incumbents
- Autodesk Construction Cloud: Broad construction software suite from Autodesk covering BIM (Revit), project management (BIM 360 / Autodesk Build), and design tools. Autodesk is a broad incumbent whose construction offerings overlap with SPIDER+ in field documentation and drawing management, but within a much wider portfolio.
- Bentley Systems: Infrastructure engineering software provider (OpenRoads, OpenBuildings, ProjectWise) widely used in plant, transportation, and large-infrastructure construction. Overlaps with SPIDER+ in plant maintenance workflows and BIM/engineering data, but at much larger enterprise scope.
- Oracle Primavera: Enterprise project portfolio management software for large-scale construction and engineering projects. Broad incumbent that competes with SPIDER+ in scheduling, progress tracking, and capital project management for tier-1 contractors.
- Trimble: Diversified construction technology provider offering field software, hardware (GPS, total stations), and BIM-related tools (Tekla). Trimble competes broadly with SPIDER+ in construction digital workflows, especially where IoT/sensor data is involved.
Emerging players
- Raken: Construction field management app focused on daily reports, photo documentation, time tracking, and safety observations. Emerging player in field documentation with overlapping functionality to SPIDER+ mobile inspection and reporting workflows.
