We are a small, independent research group working on fundamental AI research. The plan is to first solve the ARC benchmark, then use that to secure more funding, and move on to more difficult benchmarks. The research topics we want to investigate next are test-time compute, active inference, LLM-based reasoning and system2 reasoning. The ultimate goal is to do cool AI research leading up to AGI. The lab has acquired the MindsAI team recently, which is pioneering techniques such as fine-tuning models on synthetic data, test-time-training, and test-time-finetuning.

At Tuza we are building the exchange for payments processing. Like insurance & credit, payments processing is an industry priced on risk. On the surface, our product enables businesses to compare rates across multiple acquiring banks. If you dig deeper, we are building the tools for banks to accurately price their risk in real time. This feeds our comparison product and will eventually allow us to route payments from the terminal level to price optimise for our merchant customers. Today a corner shop with a turnover of £300k could save £5k+ a year in processing fees.
