Causal alternative: what to use now that Causal is enterprise
Causal was acquired by Lucanet in late 2024 and is now Lucanet xP&A — an enterprise CFO platform, not the flexible indie modeling canvas it once was. If you used Causal for big, custom models, a spreadsheet is the closest analog. If you used it to answer "is my SaaS viable — how long is my runway?", Startkeel does that, focused and one-time.
What happened to Causal
Causal joined the Lucanet Group in November 2024 and now sits inside Lucanet as "xP&A" — extended planning and analysis aimed at CFO offices, budgeting and enterprise forecasting. The flexible, loved-by-indie-founders modeling canvas is being repositioned upmarket.
For a bootstrapper who used the free or cheap Causal plan to model a startup, that is a different product than the one you signed up for.
What Causal was good at
Causal was a flexible, visual spreadsheet-replacement: build almost any model, connect variables, and see scenarios and dashboards. That generality was its strength.
Ex-users split in two: power modelers who want the flexible canvas back, and founders who really used Causal for one thing — figuring out whether their SaaS was viable and how long the runway was.
If you want the flexible canvas
If what you miss is the open, build-anything modeling power, that is exactly what is moving enterprise. The closest cheap analog is a well-built spreadsheet: full control, full flexibility, and no guardrails — you own the formulas and the mistakes.
Startkeel is deliberately not this. It does not give you a blank canvas.
If you used Causal for SaaS viability
If you used Causal to answer whether your startup survives — runway, default-alive, unit economics, cap table — Startkeel does that job directly. Instead of a blank canvas you get an opinionated engine: enter your numbers and get a benchmarked verdict, not a model you have to build and second-guess yourself.
It is narrow on purpose. One-time (€49), no subscription, a verdict in minutes — for the solo founder who wants the answer, not a modeling tool to master.
Causal versus Startkeel at a glance
Causal (now Lucanet xP&A): flexible general modeling canvas, subscription, moving to enterprise. Startkeel: focused SaaS viability model, one-time, opinionated engine with stage benchmarks.
Different tools for different jobs. For open-ended modeling, a spreadsheet is the honest cheap answer. For a fast, benchmarked viability verdict, Startkeel.
