Private equity has steadily increased its use of alternative data for deal sourcing, due diligence, and portfolio monitoring. Unlike public equity, PE often faces less frequent disclosure and fewer real-time price signals, which makes non-traditional data especially valuable for spotting opportunities and validating thesis. This post outlines how PE teams use alternative data in practice and what to consider when adding it to the process.
Where PE uses alternative data
Deal sourcing and thematic screening. Search trends, social buzz, and web or app traffic can help identify themes or sectors that are gaining attention before they show up in banker pitch books or proprietary networks. Some firms use normalized trend data mapped to sectors or companies to screen for names that are inflecting. This is most useful when combined with existing sourcing channels rather than as a standalone screen.
Due diligence. Once a target is in focus, alternative data can support commercial due diligence: demand signals (e.g. search or e-commerce interest for a product or brand), competitive context (share of voice, traffic relative to peers), and narrative risk (sentiment, news volume). The goal is to test or stress-test the investment thesis with evidence that is timelier than historical financials or management projections.
Portfolio monitoring. After the deal, the same types of data can be used to track portfolio company performance, competitive position, and early warning signs. Consistency in methodology and coverage makes it easier to compare across holdings and over time.
Data types that fit PE workflows
Search and intent data. Google, Amazon, YouTube, and similar sources provide demand and interest signals that can inform market size assumptions, growth trajectory, and seasonality. Data that is mapped to sectors, themes, or companies (e.g. Paradox Intelligence) reduces the need to build custom keyword-to-company mappings.
News and sentiment. Volume and tone of coverage can indicate when a sector or company is moving into or out of favor, regulatory or reputational risk, and narrative shifts that may affect exit timing or valuation. As with other use cases, sentiment is usually used alongside behavioral or outcome data rather than alone.
Web and app traffic. For digital-first or digitally relevant targets, traffic and engagement trends can support growth and market-share assumptions and flag execution issues early.
Transaction and spending data. Where available and legally permissible, aggregated card or receipt data can support revenue or same-store assumptions for consumer and retail names. Access and compliance requirements vary; many firms use this for a subset of deals.
Practical considerations
Universe and mapping. PE targets are often private or thinly covered. Alternative data is most actionable when it can be tied to the right entity (company, brand, sector, or theme). Platforms that support both listed and private-company or thematic mapping are better suited to PE than those focused only on tickers.
Integration with existing process. Alternative data should slot into existing sourcing and DD workflows rather than replace them. Define clear use cases (e.g. "sector screening," "commercial DD for consumer targets") and assign ownership so the data is actually used in committee or memo.
Compliance and licensing. Ensure data use complies with vendor terms, privacy rules, and internal policies. Document which datasets are approved for which use cases.
