What Calcs.com does

Calcs.com is a cloud-based structural engineering calculation platform founded in 2016 in Melbourne, Australia, by Chris Borzillo (CEO) and Steven Robinson out of frustration with spreadsheet-based workflows. The platform delivers 200+ standards-aligned calculators covering US (IBC, AISC, ACI, NDS), Australian/New Zealand (AS/NZS), Canadian (NBCC, CSA), and European (Eurocode) building codes, targeting solo structural engineers, engineering teams, manufacturers, and standards bodies. Its distinguishing features include automatic load linking that propagates load changes through connected structural members (beams, columns, footings), Reference Mode that surfaces formulas and code clauses inline for review transparency, and a Member Selector with traffic-light utilization indicators. Supplementary products include Calcs Builder for custom calculators, Analysis Calculators (Beam, Portal Frame, Truss, Cross Section), the CalcsCAD Plugin for AutoCAD and BricsCAD integration, and the ESICS module for telecommunications infrastructure design.

The business operates as a SaaS subscription product with a self-serve product-led growth motion: a 14-day free trial (no credit card required) funnels users into Basic ($79/month) and Pro ($119/month or $1,190/year with 3 concurrent seats) tiers, with custom enterprise quotes for larger firms. Customer segments span solo practitioners, engineering teams, and manufacturers, with manufacturer co-development partnerships (Atlas Tube for HSS Connections Hub, MAFI Group for ESICS telecom bracket checker) representing a distinct revenue and distribution channel that embeds product specifications inside calculations. Distribution is primarily direct via app.calcs.com, supported by content marketing, comparison pages against Enercalc/StruCalc/Tekla Tedds/Structural Toolkit, webinars, and SEO-optimized documentation.

Calcs.com has raised approximately $4.15M across two funding rounds in November 2021 ($1.65M AUD seed+) and November 2022 ($2.5M USD), both led by EVP with Shearwater Capital participation, plus early backing from Startmate. The company operates from offices in Melbourne, Toronto, and Bogota, serving engineers in 80+ countries with 12M+ lifetime designs and 80,000+ projects completed in the most recent 12-month period. In 2025, the company rebranded from ClearCalcs to Calcs.com while maintaining the same product and team. The business model combines horizontal SaaS distribution with vertical manufacturer co-development, supported by an AI-powered documentation assistant and standards-body licensing partnerships.

Broad incumbents

• Autodesk (Revit / Robot Structural Analysis): Major AEC software incumbent with Revit (BIM) and Robot Structural Analysis. Competes broadly with Calcs.com for structural engineering time and budgets, leveraging deep BIM and CAD integration that Calcs.com's nascent CalcsCAD plugin lacks.
• Computers & Structures (SAP2000 / ETABS): Developer of SAP2000, ETABS, and SAFE for structural and earthquake engineering analysis. Indirect competitor at the analysis/design level that Calcs.com addresses through its Analysis Calculators module.
• Trimble (Tekla Structures): Parent of Tekla Tedds and Tekla Structures, a broad AEC/BIM incumbent. Competitor at the enterprise level where customers expect integrated model-based workflows rather than standalone calculation tools.
• SCIA Engineer (Nemetschek Group): Structural analysis software for buildings, bridges, and industrial structures, part of the Nemetschek AEC portfolio. Overlaps with Calcs.com's analysis and design calculators (beam, frame, truss) for engineering teams in Europe.

Direct peers

• Tekla Tedds (Trimble): Structural calculation library owned by Trimble, integrated with Tekla Structures BIM. Competes with Calcs.com for structural engineer workflows and is one of the named comparison competitors on Calcs.com's site.
• RISA Technologies: Developer of RISA-3D, RISAFloor, and RISAConnection used by structural engineers for analysis and design. Overlaps with Calcs.com's structural calculation and connection design use cases, especially in steel.
• StruCalc: Structural engineering calculation software focused on wood, steel, and concrete member design. Directly compared by Calcs.com, with Calcs.com positioning its transparency and load-linking as advantages over StruCalc's black-box outputs.
• Structural Toolkit: Structural engineering calculation software for individual practitioners. Listed by Calcs.com as a direct comparison competitor where multi-code coverage and cloud collaboration are differentiators.
• SkyCiv: Cloud-based structural analysis and design software offering beam, frame, and truss calculators. Closely comparable to Calcs.com on cloud delivery, SaaS subscription model, and target audience of structural engineers and engineering students.
• Enercalc: Long-standing structural engineering calculation software widely used in US practice. Calcs.com directly compares against Enercalc in its marketing materials, positioning load linking and multi-code coverage as differentiators.
