The History of ETFLogic


Logicly is the web-based analytics platform started by the team at ETFLogic. The ETFLogic team is made up of former market makers, traders, quants, and have years of experience within the ETF and investment industry.

All of this knowledge has helped the team focus on solving problems when it comes to the complex processes of investment research and portfolio construction.


In 2017, a group of market makers and traders realized there was a huge gap in the analytics market when it came to analytics around ETF liquidity. They set out to develop tools for the capital markets teams at ETF issuers, to help them better navigate the markets.

The liquidity tools, which include our TruLiquidity ETF scoring, quickly expanded to include more tools to help answer complex quantitative questions for ETF issuers.

In our continued work with ETF issuers, it became apparent that the tools we were creating were used to answer inbound requests wholesalers were receiving from financial advisors. They were being asked questions about how to trade ETF products, how they compared to their current funds, and how they fit into their portfolios.

We began consulting with a select group of financial advisors, learning about their current workflows for ETF screening and portfolio construction. In January of 2020, we launched the Logicly platform with tailored workflows for financial advisors. Later in April, we expanded the platform with a workflow dedicated to helping financial advisors who use third party model portfolios perform research and monitor model portfolios.
