Backtest Sentinel
A compliance and audit layer that scans your quant team's backtests, research notes, and LLM-assisted memos for lookahead bias, flagging any line that cites information from after the simulation date and producing an audit-ready cleanliness report.

- Document scanner that compares each cited fact's publication date against the backtest's as-of date and scores contamination risk
- Per-researcher contamination dashboard showing who on the team is most reliant on lookback-leaking AI assistance
- Native integrations with Jupyter notebooks, Excel models, and internal research wikis to scan drafts where they live
- Regulator-ready PDF reports proving temporal cleanliness for client due diligence and internal model-governance reviews
LLM-assisted research has become standard at hedge funds and banks, and the arXiv proof that mainstream models leak the future creates new model-governance risk that compliance teams must address immediately
Look-ahead bias in LLM-assisted financial research is a documented and actively discussed problem in 2025-2026 academic and practitioner literature (multiple arXiv papers, Substack analysis), but buyer-budget evidence for a dedicated scan tool is still thin.The Ghost in the Backtest: How Financial LLMs Hallucinate Artificial Alpha ↗Look-Ahead-Bench: a Standardized Benchmark of Look-ahead Bias in Point ↗
PiT Inference already sells 'Point-in-time LLMs for finance, designed to prevent look-ahead bias and information leakage in research, backtesting, and real-world deployment' — a direct adjacent competitor, plus active academic benchmarks (Look-Ahead-Bench).PiT Inference — Point-in-Time LLMs for Finance ↗Scaling Point-in-Time Language Models - arXiv.org ↗
Compliance software for hedge funds is a known paid category with multiple vendors, and the cited paper argues lookahead leakage makes unchecked backtests 'completely worthless,' supporting willingness to pay; however, no public pricing exists for this specific niche and the buyer base is concentrated.Top 10 Best Hedge Fund Compliance Software | Ranked for 2026 ↗The Ghost in the Backtest: How Financial LLMs Hallucinate Artificial Alpha ↗
Model-governance and audit-trail obligations in asset management are structural and unlikely to fade; as LLM use in research becomes standard, lookahead detection will remain a permanent compliance concern rather than a passing trend.
Core detection is technically hard — it requires either a maintained point-in-time knowledge corpus (what PiT Inference is building as moat) or LLM-based detectors that themselves risk the same bias; producing a clean audit PDF is straightforward, but the scanner is not trivial.
