AtlasIntel did. I met Thiago (CTO) in Rio and Boston while he was doing his math PhD at Harvard, he is nice person and a fine mathematician: their methodology uses online polling on social media with micro-targeting. I only assume competitors are not leveraging social media as well as they are.
Roman, the CEO, said they will donate all their raw data from the final polls to Roper Center at Cornell for academic research[1].
atlas intel has got so many elections correctly that i really don't understand why other pollsters are not copying their methodologies.
even nate silver called then the most accurate pollster during the 2020 race.
