 # PyMC ecosystem
 
 ## General purpose
-
 - [Bambi](https://github.com/bambinos/bambi): BAyesian Model-Building Interface (BAMBI) in Python.
+- [PyMC-BART](https://www.pymc.io/projects/bart/en/latest/): Bayesian Additive Regression Trees for Probabilistic programming with PyMC
+- [PyMC-Extras](https://github.com/pymc-devs/pymc-extras): A collection of PyMC extra features such as cutting-edge methodologies, highly specialized statistical distributions, or complex models appear.
 - [calibr8](https://github.com/JuBiotech/calibr8): A toolbox for constructing detailed observation models to be used as likelihoods in PyMC.
 - [CausalPy](https://github.com/pymc-labs/CausalPy): A package focussing on causal inference in quasi-experimental settings.
 - [SunODE](https://github.com/pymc-devs/sunode): Fast ODE solver, much faster than the one that comes with PyMC.
 - [pymc-learn](https://github.com/pymc-learn/pymc-learn): Custom PyMC models built on top of pymc3_models/scikit-learn API
+- [BART-Survival](https://github.com/CDCgov/BART-Survival): BART-Survival is a Python package that supports discrete-time Survival analyses using the non-parametric machine learning algorithm, Bayesian Additive Regression Trees (BART).
+
 
 ## Domain specific
 
+- [PyMC-Marketing](https://www.pymc-marketing.io/en/stable/): Marketing analytic tools like Marketing Mix Modeling (MMM) or Customer Lifetime Value (CLV)
 - [Exoplanet](https://github.com/dfm/exoplanet): a toolkit for modeling of transit and/or radial velocity observations of exoplanets and other astronomical time series.
 - [beat](https://github.com/hvasbath/beat): Bayesian Earthquake Analysis Tool.
