Foundation provides a data layer for financial statements that models information as explicit, time‑bound assertions rather than mutable rows. Each assertion includes effective and knowledge dates, versioning for amendments, and built‑in provenance linking back to the original filing, enabling precise as‑of queries and audit‑ready analytics. The system’s canonical primitives are designed for seamless integration into research, analytics, and production pipelines without requiring downstream hacks.

Problem
Developers building financial models, research tools, or analytics platforms must extract data from regulatory filings that are frequently revised, restated, and lack clear lineage, leading to unreliable historical values and non‑reproducible queries.
Solution
Foundation (Protos Systems) offers a deterministic financial data infrastructure that converts raw regulatory filings into structured, time‑aware assertions. Each data point is stored as an explicit assertion with effective and knowledge dates, preserving every amendment and restatement as a first‑class version. Built‑in provenance links every number to its original filing, version, and source, enabling precise as‑of queries without look‑ahead bias. The Arche API provides developer‑first access to these canonical primitives, allowing seamless integration of reliable financial intelligence into research, analytics, and production systems.
Target Audience
Primary customers are quantitative researchers, fintech developers, and data engineers who need reliable, versioned financial data for modeling, backtesting, and analytics applications.
