Mattermark in depth

Read the full write-up

Overview

Mattermark is a company research service for finding and tracking fast-growing businesses and investors. It is best suited to investors and sales or business development teams that need recurring company research or Salesforce enrichment. Its broad profiles and tracking tools are useful, but per-seat costs and annual commitments make it a poor fit for occasional lookups.

Key features

Profiles, signals, and research

Company profiles cover more than 80 fields, including geography, industry, revenue, personnel, funding, and employee growth. Mattermark also monitors changes in team size, web traffic, and media mentions. Together, those details support screening and ongoing company monitoring, not just one-off searches. Users can search, filter, and sort records, then follow companies with saved searches, custom lists, and news notifications.

Mattermark says it processes millions of news articles and websites daily using machine learning, web crawlers, primary sources, and natural language processing, with in-house analysts verifying data daily. That mix is intended to keep research and growth signals current. It is still a research input, not a substitute for checking a company before making a consequential decision.

Salesforce and API

The Salesforce integration syncs company information into leads and other Salesforce objects, and supports triggers and actions on data fields. It is a practical fit for teams that want company enrichment embedded in Salesforce; the per-seat charge and annual contract are less attractive for small teams with sporadic needs.

The API provides REST and GraphQL access to company and investor data, including lists, company details, news, similar companies, and funding events. An API trial includes 100 free calls. That makes it possible to evaluate an integration before committing, while production access carries its own price and request limits.

Pricing

Mattermark has a free iOS option and several paid paths, but they serve different jobs. The free app is the lowest-commitment way to access company data and news; it does not replace the saved research, export, Salesforce, or API plans.

Company Data and News on iOS: free, with no account required. Best for individuals who want free iOS access to company information and news.

Mattermark Standard: $49 a month, billed month to month, per user. Includes company data, news, public and saved lists, recommended searches, and funding and venture capital portfolio data. This is the flexible paid option for an individual researcher, but it does not include the CSV export available on Professional.

Salesforce Data Enrichment: $49 a month, billed on an annual contract, per seat. Includes Salesforce lead enrichment and triggers and actions for data fields. It suits Salesforce teams that will use enrichment throughout the year; the annual term is a meaningful commitment at the same monthly price as Standard.

Mattermark Professional: $500 a month, billed on an annual contract, per user. Includes Standard features and CSV export. The export may justify the step up for users who need to work with data outside the service, but the listed annual commitment makes it a costly choice for a single occasional user.

Company & Contact Data API: $999 a year, billed on an annual contract, for up to 20,000 requests per month. It is aimed at developers or organizations integrating data into their own workflows; the monthly request ceiling matters for sustained or high-volume use.

Mattermark Enterprise: custom pricing. Multiple seats, team sharing, Google Sheets and Windows Excel, and a dedicated account manager make it the team-oriented option.

Republish API: custom pricing on a yearly basis, with plans starting at 50,000 API requests per year. It includes a license to use data in publicly distributed or paid products, a distinct requirement from internal API use.

Standard is the clearest choice for month-to-month company research. Salesforce, Professional, and the API plans all require annual contracts, while enterprise and republishing costs are custom. The 14-day trial offers a short window to assess the paid service before choosing a plan.

Platforms

Mattermark supports web, iOS, API, a browser extension, and Windows access. Its listed integrations and access options also include Excel and Google Sheets, with Google Sheets and Windows Excel included on the Enterprise plan. The iOS plan is free; other platform access depends on the applicable paid offering.

Who it's for

Investors can use the profiles, funding information, portfolio data, and growth signals to identify and follow companies. Sales and business development teams are better served when they can turn company research into Salesforce enrichment or recurring prospect lists. Professional services firms that need repeatable company research are another natural audience. Buyers who need only occasional lookups, or want a low-cost paid plan with a short commitment, should weigh the free iOS access against Standard's per-user fee and the annual terms on the more specialized plans.

Pros and cons

Pros: Profiles combine more than 80 company fields with signals such as team-size and web-traffic changes, supporting both screening and continued monitoring.

Pros: Saved searches, custom lists, and news notifications give repeat research a structure rather than requiring users to start from scratch.

Pros: Salesforce enrichment supports syncing and field-based triggers and actions, while the API offers both REST and GraphQL access.

Cons: CSV export is confined to the $500 a month Professional plan, billed annually, making routine exports expensive for many individual users.

Cons: Salesforce enrichment costs $49 a month per seat on an annual contract, so a team pays for a year even if its enrichment needs change.

Cons: The API plan caps usage at 20,000 requests per month; republishing data requires a separate license and custom-priced plan.

Alternatives

For broader browsing, start with the Company Databases category; teams focused on enriching sales records can compare the Lead Enrichment Software category. Choose Wappalyzer when its free plan's technology lookups, email verifications, website alerts, and sample lead lists fit the job. Landbase B2B Database is another option with free credits and custom pricing.

ZoomInfo is worth comparing if a permanent free plan with no credit card or commitment is more important than a published paid price. Global Database offers a free tier with five monthly credits and CSV/PDF viewing, plus a $99 a month Pro plan. For API-led prospect data, compare PredictLeads; for limited profile research, PrivCo has a free Researcher plan. BuiltWith may suit technology lookups, with 10 detailed lookups per day free and an Advanced plan at $144 a year. Owler is another business-information alternative with a free community membership.

Verdict

Mattermark is a strong fit for investors and teams that need to monitor company growth over time, build research lists, or enrich Salesforce records. Its combination of detailed profiles, change signals, and workflow access is the main reason to choose it. Look elsewhere if you need only occasional data, inexpensive CSV export, or high API volume without an annual or custom-priced commitment.

Verdict

Mattermark combines company profiles, growth signals, saved research tools, Salesforce integration, and API access. Free iOS access is available, while paid plans include per-user, annual-contract, and API options at distinct prices.
