Questions & Answers

As answered by people managing Memory.com and Aperiodic.io.

What makes your product unique?

Aperiodic.io's answer:

Aperiodic sells the feature layer between raw ticks and finished analytics: 220 point-in-time microstructure, liquidity and order-flow metrics (Kyle's lambda, Amihud illiquidity, flow toxicity, flow entropy, slippage in basis points and more), computed from raw order book and trade data with no look-ahead. You get them as parquet through a CLI, a REST API or the Python SDK, and the raw trades, quotes and derivatives data behind them are available too. A preview slice of every dataset downloads with one CLI command and no API key.

How would you describe the primary audience of your product?

Aperiodic.io's answer:

Quant researchers and systematic traders working on crypto perpetual futures: researchers at systematic funds and prop desks, independent quants, and students who need order-flow and liquidity features for backtests and models. Self-serve plans carry a personal licence; funds and desks use the Institutional plan for commercial use.

Why should a person choose your product over its competitors?

Aperiodic.io's answer:

If you research crypto perpetuals, the usual choice is raw ticks you have to engineer into features yourself, or sales-gated analytics you cannot try first. Aperiodic gives you the computed features directly, so you can test an order-flow idea the same day instead of building a pipeline first. You can also try it before paying: the preview needs no API key or signup, and self-serve plans start at $29 a month, billed yearly, with no sales call.
