Causal

Causal is a business planning and financial modelling platform positioned as a next-generation alternative to spreadsheets. Founded in London and acquired by LucaNet in 2024, the company built its product for finance and operations teams who find that complex spreadsheet models become fragile, difficult to audit and hard to share as a business grows. Causal's approach replaces cell references with human-readable variables and formulas, and adds a time dimension and categories natively, so that models can be built more quickly, understood more easily and presented through interactive dashboards that non-finance stakeholders can explore.

Users construct models by defining variables, such as revenue drivers, headcount plans and expense categories, with formulas written in plain language that automatically apply across time periods and dimensions like region, product or department. This structure reduces errors and makes it straightforward to extend models. Scenario planning allows teams to compare alternative assumptions side by side, and Monte Carlo simulation and ranges help represent uncertainty in forecasts. Causal connects to accounting systems including QuickBooks and Xero, to HR and payroll systems, to data warehouses and to spreadsheets, so that actual results feed models automatically and variance analysis can be performed against plan. Common use cases include financial forecasting, budgeting, headcount planning, SaaS metrics, fundraising models and board reporting. Interactive dashboards and reports can be shared with executives, investors and department heads, who can adjust inputs within permitted limits to explore what-if questions without breaking the model. Collaboration features include comments, version history and access controls. Templates provide starting points for startups and scale-ups. As part of LucaNet, Causal is increasingly aligned with broader financial performance management capabilities, which may affect packaging and roadmap. The platform is aimed at founders, CFOs, finance teams and operators at startups and mid-sized companies, particularly in technology, that want modern, collaborative planning tools. A free version and a free trial are available, with paid plans starting from around USD 250 per month.
