Survival analysis built for HTA submissions.
Model, compare, and export parametric survival curves without writing a line of code. Built for health economists and evidence teams.
No credit card required · 14-day trial · Cancel anytime
Built on flexsurv and IPDfromKM. Aligned with NICE TSD14. Founded by health economists, in Helsinki.
PRODUCT
Everything an evidence team needs.
From raw data to a submission-ready
survival analysis, in one tool.
KM digitization & IPD
reconstruction
Bring digitized Kaplan-Meier points with at-risk tables. The Guyot algorithm (via IPDfromKM) reconstruct individual patient data automatically.
Parametric survival models
Fit exponential, Weibull, log-normal, log-logistic, Gompertz, and generalised gamma distributions. AIC/BIC ranking built in.
Cure-fraction models
Composite curves combining parametric extrapolation with SMR-adjusted population mortality, for therapies with long-term responders.
Two-arm comparison
Side-by-side intervention vs control with per-distribution RMST differences and incremental life-year gains
Excel exports for downstream models
Fitted parameters, variance-covariance matrices, and model comparison summaries ready for your CE workbook.
Workspaces for teams
Save, version, and hand off analyses cleanly between modeller and reviewer.
HOW IT WORKS
From published curve to fitted
survival model in four steps.
Bring your data
Upload digitized KM points with at-risk tables, or your own IPD.
Reconstruct
The Guyot algorithm rebuilds individual patient data automatically.
Fit and compare
Run parametric and cure-fraction models, rank by AIC/BIC
Export
Excel outputs that plug into your downstream CE workbook.
