What Is Alternative Data?

Alternative data is any data gathered from non-traditional sources — i.e., outside of company filings, earnings calls, and broker research. It provides investors and corporate professionals a more granular, real-time view of markets than traditional financial data alone. What makes alternative data valuable is its signal advantage: Because it reflects market reality before it shows up in formal financial disclosures, analysts who use it can anticipate trends, spot risks earlier, and make more confident decisions. With AI now capable of synthesizing these signals at scale, the edge has shifted from simply having the data to having the right tool that helps you act on the data.

Traditional vs Alternative Data

What Are the Types of Alternative Data?

Alternative data falls into three main categories, depending on how it originates. Understanding the source helps identify which data type is most appropriate for a given research question.

Individual-Generated

Data produced by humans is largely unstructured, and highly valuable for understanding consumer sentiment, behavior, and expert perspective. Examples include:

Expert call transcripts & AI-led expert interviews
Social media commentary & sentiment
Product reviews and ratings
Web traffic and app usage data
Job postings and talent signals

Business Process-Generated

Structured data generated through commercial and institutional operations is a reliable indicator of business performance and financial health. Examples include:

Credit card and transaction records
Bank and payment processing data
Supply chain and logistics data
Government and regulatory filings
Corporate patent filings

Sensor-Generated

Unstructured data captured by physical and digital sensors is useful for tracking real-world activity that precedes financial results. Examples include:

Satellite and aerial imagery
Geolocation and foot traffic data
Weather and environmental signals
IoT and industrial sensor feeds
Cell tower and mobility data

AlphaSense Brings It All Together in One AI Platform

AlphaSense combines alternative data with fundamental research, proprietary expert insights, and structured financial data — all searchable and discoverable through a single AI-powered interface. This all-in-one platform cuts out the need for managing multiple data vendor relationships.

Expert Insights: The Most Powerful Alternative Data Source

First-hand perspectives from former executives, industry operators, competitors, and customers are the most differentiated and valuable form of alternative data and also the hardest to access at scale.

Tegus Expert Insights, integrated within the AlphaSense platform, gives financial services and corporate professionals access to one of the world's largest expert call transcript libraries, covering companies across public and private markets. Rather than scheduling individual calls or paying per-hour for primary research, you can search across thousands of structured expert conversations instantly.

AI-generated summaries, key takeaways, and sentiment analysis allow you to get up to speed instantly and spot new trends early. Period-over-period sentiment tracking lets you spot when expert opinion on a company or theme is shifting quarter to quarter, before it surfaces in public filings.

For situations requiring primary research, AI-Led Expert Calls can be launched directly from research projects within the platform — combining the depth of a live expert interview with AI-powered synthesis of follow-up questions and key findings.

Sentiment Analysis: What the Data is Actually Saying

Sentiment analysis is another highly valuable form of alternative data, which can be used to uncover underlying meaning in expert commentary or C-suite statements in earnings transcripts.

AlphaSense’s NLP-powered sentiment analysis parses tone and language nuance in financial documents and expert calls, allowing you to quickly understand the market landscape and outlook on specific companies. Instead of skimming thousands of documents for signal, the platform flags positive, neutral, or negative sentiment inline with every source you’re analyzing.

Additionally, quarter-over-quarter sentiment paints a longitudinal picture, making it easy to detect shifts in management tone, analyst confidence, or expert opinion as they develop rather than long after the fact.

What Are the Main Use Cases for Alternative Data?

Alternative data is useful because it’s immediate, frequently updated, and provides added context to certain trends or performance indicators that are otherwise ambiguous. It is most powerful when embedded into research workflows — not treated as a standalone feed. Here’s how our clients across financial services and corporate strategy use it to enhance their research and analysis:

Due Diligence

Buy-side analysts use alternative data to validate investment theses and gain a 360 degree view of all potential benefits and risks before committing capital. Expert calls are particularly useful here where former executives and industry insiders can shed light on the inner workings of a company or industry and offer a perspective you won’t find anywhere else.

From there, AlphaSense streamlines and accelerates due diligence with our Due Diligence Workspace. Centralizing VDR content, internal content like CIMs and past research, and AlphaSense’s exclusive market intelligence in a single project space, Workspace then layers on specialized AI agents purpose-built for rigorous VDR analysis, due diligence, and investment committee preparation.

Within each Workspace, deal teams can sync thousands of data room documents from Intralinks, Egnyte, SharePoint, Box, and more while preserving folder structure. They can interrogate both their own materials and the broader AlphaSense content library side-by-side. Pre-built or custom Workflow Agents allow you to embed your strategic approach into every deal and make the process repeatable.

Portfolio Monitoring

Timeliness is critical when managing a portfolio. Alternative data sources update continuously, allowing analysts to detect material changes before they appear in quarterly filings.

AlphaSense's smart alerts and watchlists notify you immediately when relevant signals emerge across your coverage universe — whether that's a shift in expert sentiment on a portfolio company, an unusual earnings call tone, or a supply chain signal in a monitored sector. Custom Workflow Agents can also run automatically on a regular cadence, delivering research briefs without prompting.

Competitive Intelligence

Alternative data fills critical gaps in competitive research — whether you're a corporate strategist building a market entry plan or a sell-side investor mapping competitive moats ahead of an earnings cycle.

Expert calls conducted by buy-side analysts go deep on competitive dynamics: tech stacks, channel strategy, pricing moves, and industry headwinds. Combined with sentiment analysis across management commentary, AlphaSense gives you a real-time picture of the competitive landscape.

Deal Sourcing

Hedge funds, PE firms, and M&A teams use alternative data to identify opportunities with the highest potential ROI and lowest risk. Consumer foot traffic, social media activity, and transaction data can reveal whether a business is actually performing the way its management claims — before any deal process begins.

In AlphaSense, you can use our AI agents to go from a blank page to an investment memo in minutes. Quickly spot trends or themes sparking or refining areas of potential investment with Generative Search. Use Generative Grid to get scalable expert transcript comparisons that surface hidden signals of opportunity or red flags.

5 Ways Expert Insights Lead to Successful M&A

Forecasting & Risk Management

Alternative data offers some of the most reliable leading indicators for stock price movement and company performance. Online sentiment, transaction data, and expert opinion all update before quarterly results are published, making them invaluable for building forward-looking models.

AlphaSense's Financial Data offering combines structured quantitative financials with qualitative market intelligence in one conversational interface. In Generative Search, ask a natural-language question like, “What drove revenue growth last quarter?” Then, receive both the financial figures and the relevant management commentary or expert insights — without toggling between systems.

Agentic Research Workflows

Rather than manually pulling together alternative data signals each week, Workflow Agents can monitor, synthesize, and deliver structured outputs on a schedule. This enables teams to automate the recurring research tasks that consume analyst time and require a decision at every step.

Pre-built agents are available for Investment Banking, PE/VC, and Investor Relations workflows, with the ability to create custom agents for specific coverage areas or recurring reports. The result: a research operation that runs continuously in the background — surfacing alternative data signals the moment they become relevant, not when someone thinks to look.

Alternative Data Frequently Asked Questions

What is the difference between alternative data and traditional data?

Traditional financial data includes financial statements, earnings calls, investment guidance, fundamental data sets, company presentations, and broker research. It is available through a company's investor relations department.

Alternative data encompasses all data sources outside of these — including expert call transcripts, sentiment signals, geolocation data, social media activity, and transaction records. Its defining characteristic is that it reflects market reality in real time, before it surfaces in formal disclosures.

Who benefits from using alternative data?

Alternative data is valuable for functions across financial services and corporate strategy. Hedge funds and asset managers use it to validate investment theses and identify price-moving signals. Private equity firms rely on it for deal sourcing and target assessment. Investment banks use it for pitch preparation and deal risk identification. Corporate strategy teams use it for competitive landscaping, market forecasting, and go-to-market intelligence.

Algorithmic traders (quants) use structured alternative datasets to build and calibrate trading models. The barrier to access has dropped significantly — what once required a dedicated quant data team is now easily accessible through platforms like AlphaSense.

What are the drawbacks of using alternative data?

Alternative data is extremely effective in telling a story, but it’s important to remember that it’s only telling part of the story. It is always most effective when combined with fundamental research rather than used in isolation. Additionally, the signal-to-noise ratio varies significantly by data type and provider, and interpreting unstructured data requires analytical judgment that technology alone cannot replace.

Privacy and regulatory considerations are also considerations. Data collection practices are subject to evolving frameworks including GDPR in Europe and expanding state-level privacy laws in the U.S. When evaluating alternative data sources, it's important to assess both the provider's data sourcing practices and compliance posture.

Why combine alternative data with fundamental research?

Alternative data is effective at reinforcing and challenging what the fundamental data says — but it is not granular or verifiable enough to replace a full research process on its own. The most rigorous investment and strategic decisions come from synthesizing both: fundamental data provides the foundation, and alternative data adds real-time signal and contextual depth.

AlphaSense is purpose-built for this: the platform provides access to both traditional sources (SEC filings, ESG reports, broker research) and alternative datasets (expert calls, patent data, sentiment analysis) in a single AI-powered interface — eliminating the fragmentation that slows most research workflows.

How does AlphaSense differ from other alternative data providers?

Most alternative data providers deliver raw data feeds that require downstream processing — a model suitable for quant teams with dedicated engineering resources. AlphaSense takes a different approach: It combines alternative data and fundamental research in a unified AI platform, then uses generative and agentic AI tools to surface decision-ready insights rather than raw inputs.

The practical difference is that AlphaSense reduces time-to-insight — tasks that previously required days of synthesis can be completed in minutes. For teams that need both the depth of alternative data and the speed of AI-powered synthesis, this integrated model is meaningfully more efficient than managing separate vendor relationships.

How do I choose an alternative data provider?

Alternative data providers are not all made equal — depending on the purpose and scope of your investment research, you may want to invest in a data provider that does not merely hold the data, but also separates the signal from the noise by understanding the kinds of insights you are looking for.

Additionally, some alternative data vendors are better for consumer-facing corporations, while others are better suited for financial services companies.

If you plan on utilizing alternative data heavily in your research and workflow process, you may want to select a provider that specializes specifically in alt data and thus offers access to a wide variety of it. However, if you are looking for a more robust multi-faceted approach to research, one that allows you to incorporate alternative data but also offers access to a vast content universe of fundamental research, you may benefit from an all-in-one market intelligence platform like AlphaSense.

AlphaSense allows you to seamlessly add alternative data to your research process with our expert transcript library and our built-in sentiment analysis feature, so that you can conduct more thorough and efficient research.
