Its products support global equities, futures and foreign exchange trading. BestEx offers execution algorithms, transaction cost analysis, market-impact models and its Algo Management System, while AMS One provides banks and brokers with an end-to-end platform for operating algorithmic execution businesses. Pulse Analytics and Pulse AI provide pre- and post-trade analytics, with Pulse AI connecting proprietary trading models and market data to AI assistants. The company serves hedge funds, asset managers, CTAs and sell-side institutions and operates offices in the United States, United Kingdom, India and Singapore.
BestEx Research offers engineers and quantitative researchers the opportunity to work directly on low-latency trading systems, execution algorithms, exchange simulators, market-impact models and large-scale market-data pipelines. The company has grown to about 75 employees globally, with Bengaluru serving as a core engineering and research hub rather than an offshore support center. Current roles advertise equity and cash bonuses, structured training in market microstructure and algorithmic trading, direct collaboration with senior quants and traders, and potential international mobility. BestEx also won Euromoney's 2026 award for World's Best Algos and Execution Services, providing candidates exposure to research-driven technology used in live institutional markets.
