About DataBroker

What is DataBroker?

A course and a set of tools for people who arrange data deals: finding a company that holds data a buyer would pay for, checking who owns the rights, putting a rough value on it, getting the agreements signed and seeing the sale through to payment.

Who is it for?

People who want to work as brokers of company data, and data owners who want to understand how a sale works. The course assumes no background in data or law; knowing an industry well helps you find sellers in it.

Is DataBroker a data marketplace?

No. It isn't a self-serve public marketplace and doesn't replace one. Marketplaces give sellers reach, billing and delivery that DataBroker doesn't offer, and brokers often use them as one route to buyers among several.

Who writes the pages on this site?

The DataBroker team. Blog posts are drafted with help from AI tools, and a person checks each one against its sources and approves it before it goes live. Figures link to their sources with the date they were checked.

The course and the app

What's free and what's paid?

The guides, glossary, comparisons, law pages, blog and free tools on this site are open to everyone. The course and the app's tools are paid, with 12 months of access.

What does the app include?

A lead finder and a CRM for the companies you approach, estimations that give an advisory value range, contract templates tracked from draft to signed, an inventory of the assets you can sell, listings, and a view of data for sale and open buyer requests.

Where do I sign in?

The course and the app live at app.data.broker. The Get started buttons on this site take you to its sign-in page.

Will I make money from the course?

We can't promise that, and we don't publish typical earnings because we can't verify them. What a broker earns depends on the deals they find and close, and many conversations end without one.

Data, tools and the law

What kind of data does DataBroker deal with?

Company data: codebases, task sets and raw data such as recordings or document archives, mostly for AI labs that license data to build models. It doesn't cover building or selling profiles of consumers, which is a different business under different laws.

Do the free tools send what I type to DataBroker?

No. The free tools run in your browser and what you type isn't sent to us or stored. The codebase value calculator asks GitHub's public API about the repository you name, straight from your browser.

Is an estimate what my data will sell for?

No. Estimates are rough guides, not offers. What a dataset sells for depends on who wants it and on the rights its owner holds, so treat any range as a starting point for a conversation with buyers.

Are the contract templates and generators legal advice?

No. They give you a starting document and explain what each part is for. Have a lawyer review any agreement for your own deal before you rely on it.

Do I have to register as a data broker?

It depends on what you sell. Some US states require businesses that sell personal information about consumers to register; brokering company data with the personal information taken out is a different situation. The law pages cover several state laws and registries in general terms; ask a lawyer about your case.

Free tools

NDA generator

Is the NDA generator really free?

Yes. There is no account, no email gate and no watermark. The form and the PDF are both made in your browser.

Do you keep what I type?

No. Nothing you enter is sent to our servers. Close the tab and it is gone, so download or copy the result before you leave.

Data pricing calculator

How do I price data I have never sold?

Start from your cost to deliver plus a margin, which is the floor. Then look for any quote for similar data, even rough, and use it as your base rate. Adjust for freshness and exclusivity.

Should I charge per record or per year?

Per record suits one-off snapshots. A yearly fee suits feeds that update. You can use the calculator for a yearly fee by pricing one year's licence.

PII scanner

Is my file uploaded?

No. The file is read by your browser and scanned there. Nothing is sent to us or stored, and closing the tab clears it.

Does a clean result mean the file has no personal data?

No. It means none of these patterns matched. Names, addresses and free-text notes can still identify people, so read the file too.

Data value calculator

How much is a dataset worth?

There is no single price. It depends on who is buying, what they can do with it, how fresh it is and whether you have the right to license it. A range from several methods is more honest than one number.

Which method is most accurate?

The market method, when you have a real comparable quote. Without one, the cost method gives a floor and the income method gives a ceiling for a specific buyer.

Letter of intent generator

Is a letter of intent legally binding?

Usually only in part. This one says that only the exclusivity, confidentiality, costs, expiry and governing law clauses bind. The rest records current intent. Courts look at the words used, so keep that clause.

What is the difference between a letter of intent and a term sheet?

Very little in practice. A term sheet is often a table of terms; a letter of intent is the same content written as a letter and signed. Both lead to a definitive agreement.

AI training data value estimator

How much is my company's data worth to AI companies?

For video, photos, audio and books, the estimator multiplies what you hold by prices AI buyers were reported to pay. For other types no price is public, so the honest answer is that it is set deal by deal.

Where do the prices come from?

From news reports of specific deals, mostly via Bloomberg, each linked under the result and in Sources. We add a price only when a named outlet published it.

Codebase value calculator

Does this tool see my code?

No code is downloaded. Your browser asks GitHub for the repository's public details and language byte counts only, and nothing passes through our servers.

Why $100 an hour?

It is an assumption for a fully loaded cost, meaning salary plus benefits, equipment and management. The US median wage for software developers is lower; change the figure to match your market.

Data broker lookup

How do I check if a company is a data broker?

Search its name or website in the lookup above. If it is registered in California or Oregon you will see the registration as the state published it. Search Texas's and Vermont's registries on their own sites too.

Is the data broker registry public?

Yes. California, Texas, Oregon and Vermont all publish their registries. California and Oregon also offer downloadable files, which is what this lookup is built from.

Guides

Selling data your company holds

Can a small company sell its data?

Yes, if it owns the data and may license it. Size matters less than scarcity: a small firm with years of specialist records in a narrow field can hold something a large buyer can't easily collect.

Do I lose my data when I sell it?

Not if the deal is a licence, which is the usual form: you keep the data and grant the buyer a right to use a copy. An exclusive licence can stop you licensing it to anyone else in the agreed field for the agreed period, so read that clause carefully.

Data monetization strategy

What are examples of data monetization?

A retailer using sales data to cut waste (improving), a payroll provider showing customers salary benchmarks (wrapping), a logistics firm selling a shipping index (an insight product), and a closed software company licensing its codebase to an AI lab (a data licence).

Is selling data the most profitable way to monetize it?

Not necessarily. MIT's research suggests most companies get more from improving their own work first. Outside sale suits data that is scarce and clean to license, and it carries more legal and reputational risk than internal use.

How to become a data broker

Do I need a licence to be a data broker?

Not for brokering business datasets under the registry laws we checked. California, Vermont, Texas and Oregon require registration from businesses that sell personal information about consumers they don't have a direct relationship with. If personal data is in your deals, ask a privacy lawyer which rules apply, including any sector-specific ones.

How do data brokers get paid?

Usually through a commission or finder's fee: a share of the deal value, or a fixed fee, agreed with the seller in writing before you introduce buyers. The rate is negotiated deal by deal, so put it in a signed agreement rather than relying on an email.

How to sell software you have built

Can I sell software I wrote at my old job?

Usually not. Code written for an employer generally belongs to the employer under employment terms. Check your contract before offering it to anyone.

Can I sell my startup's code after it shuts down?

Often, if the company still owns it and the people with authority approve the sale. In insolvency, the administrator or court decides. Check investor and lender rights, and remove customer data first.

How to price data

Should I charge per record or a flat fee for a dataset?

Charge per record when buyers want different amounts or slices and the unit is easy to count. Charge a flat fee when the buyer takes the whole set and the value lies in having all of it, such as a complete codebase or a full archive.

How much more should exclusive data cost?

There is no standard multiple. Price exclusivity against the sales the seller gives up: how many other buyers exist, and for how long the grant runs. Narrow it by time, territory or field of use to keep the premium reasonable.

Data valuation

How much does data sell for?

There is no price list. What a dataset sells for depends on how useful it is to a particular buyer, the rights that come with it and how hard it is to get elsewhere. That is why this guide builds a range from the three approaches instead of quoting a figure per row.

What is the most common way to value data?

In practice, cost-based methods: adding up what the data took or would take to produce. They are easy to defend but tend to understate value, so sellers usually check them against market comparables and the buyer's likely gain.

Where to sell data

Is there one best data marketplace?

No. The right one is where your buyers already work. A buyer on AWS will find AWS Data Exchange easiest; a Snowflake shop will prefer a Snowflake listing. For data that needs explaining, no marketplace replaces a direct conversation.

Can individuals sell data on AWS Data Exchange?

AWS says providers must be permanent residents or citizens of an eligible jurisdiction, or a business organised there, be registered AWS Marketplace sellers and be qualified by the AWS Data Exchange team. In practice it is built for businesses with data products and customer support.

How to sell data to companies

What kinds of companies buy data?

Mainly investment firms, AI labs and model builders, marketing and sales teams, and product or analytics teams filling gaps. Governments and researchers buy too, under their own procurement rules.

How do I find a buyer's data team?

Look for job titles such as data sourcing, data partnerships, data acquisition or alternative data on professional networks, and for people who speak at data industry events. A warm introduction from a broker or a shared contact helps most.

Data broker laws

California data broker registry and the Delete Act

Where is the California data broker registry?

CalPrivacy publishes it on its website. It lists each registered broker with contact details and the disclosures the broker filed, and it is the list DROP uses to route deletion requests.

When is the California data broker registration deadline?

January 31. Brokers register and pay between January 1 and January 31 of each year for the year after they began brokering Californians' data.

Glossary

Data as a service (DaaS)

What does DaaS stand for?

In data work it stands for data as a service. In IT infrastructure the same letters often mean desktop as a service, which is unrelated hosted virtual desktops.

What is the difference between DaaS and SaaS?

SaaS gives you software to use. DaaS gives you data to use in your own software. Many products mix both, such as a sales database with a search app on top.

3 more about Data as a service (DaaS)

Data broker

Is a data broker legal?

Yes, data brokers operate legally in the United States, but they are increasingly regulated. Depending on what they sell, they may need to register in states such as California, Vermont, Texas and Oregon, honour opt-out and deletion requests, and follow the Fair Credit Reporting Act when their data is used for eligibility decisions.

What is the difference between a data broker and a data provider?

In practice the words are often swapped. Data provider usually describes a company selling its own compiled product, such as company contact data. Data broker is broader and includes intermediaries who resell or arrange the sale of data owned by others.

AI dataset

What are examples of AI datasets?

Labelled photos for object recognition, transcribed audio for speech models, pairs of questions and answers for chatbots, historical transactions marked as fraud or not, and code repositories with commit history are all common types.

How big does an AI dataset need to be?

It depends on the task and on whether the buyer is training from scratch or adapting an existing model. Adapting a model to a narrow task can work with far fewer examples than building one, which is why small specialist collections still find buyers.

Synthetic data

Is synthetic data as good as real data?

For some jobs, yes: labs report generating most of their alignment examples and large amounts of reasoning practice. For factual knowledge and rare cases, research and lab reports say models trained only on synthetic data do worse, so real data is still needed.

What is model collapse?

The loss of quality that happens when models are trained over and over on content produced by earlier models. A 2024 Nature paper found that rare cases from the original data disappear first. Keeping real data in the mix appears to prevent it.

Data enrichment

What is an example of data enrichment?

Adding an industry category and company size to a list of business accounts, attaching local weather to daily store sales, or tagging support tickets by topic are all forms of enrichment.

What is the difference between data enrichment and data cleansing?

Cleansing corrects or removes what is already in a dataset: typos, duplicates, invalid values. Enrichment adds something new. Most projects clean first, because matching dirty records to outside sources gives poor results.

2 more about Data enrichment

First-party data

Is first-party data always personal data?

No. Plenty of it describes machines, stock, routes or prices rather than people. Customer records are personal, but a factory's yield logs or a carrier's depot timings may contain nothing about any individual.

Can a company sell its first-party data?

Often, but not automatically. It depends on what customers were told, what client contracts say and which privacy laws apply. Non-personal operational records are usually the easiest to license.

Data types

B2B data providers

Which B2B data provider is the most accurate?

It depends on your market. Coverage differs by country, industry and company size, so the only reliable answer is a blind test on a sample of accounts you already know.

Is it legal to buy B2B contact data?

Generally yes in the United States, with conditions on how you use it: CAN-SPAM for email, TCPA and do-not-call rules for phones, and state privacy rights for the people named. In the EU and UK you also need a lawful basis under GDPR.

2 more about B2B data providers

AI training data

Where do AI companies get their training data?

From scraped public web content, licensed archives from publishers and platforms, open datasets, synthetic data their own models generate, and paid human work such as writing, labelling and rating answers.

Can a company sell its own data for AI training?

Often, if it owns the rights and the data isn't restricted by customer contracts, privacy notices or third-party licences. Those three checks decide most deals.

2 more about AI training data

Intent data providers

Is intent data accurate?

It is a probability, not a fact. Mapping anonymous reading to a company is imperfect, especially for remote workers and small firms. Test it against your own closed deals before relying on it.

What is the difference between first-party and third-party intent?

First-party intent comes from your own website, ads and emails. Third-party intent is licensed from someone else and shows research happening on sites you don't control.

Firmographic data providers

What is the difference between firmographic and technographic data?

Firmographic data describes the company itself: industry, size, revenue and location. Technographic data describes the technology it uses, such as its CRM, cloud provider or analytics tools.

Can I get firmographic data for free?

Aggregate counts, yes: Census County Business Patterns is free. Named company records with size and revenue estimates for private firms are mostly paid.

Leads

Lead generation companies

What does a lead generation company do?

It attracts people interested in a product, collects their details or connects their call, and sells that contact to businesses that want customers, per lead, per click, per call or as a commission on a closed sale.

How much do lead generation companies charge?

Most large ones don't publish prices. They sell through real-time auctions, account managers or memberships, and the price depends on the vertical, the targeting and whether the lead is exclusive.

Real estate leads

How much do real estate leads cost?

Published figures range from about $20 to $60 per contact in many markets to several hundred dollars in competitive metros, and Zillow's reported averages in 2026 were $223 in major metros and $139 elsewhere. Pay-at-closing programmes instead take roughly 15% to 40% of the commission.

Can I sell real estate leads without a licence?

Selling contact data at a flat price is treated differently from taking a share of a commission, which most states restrict to licensed people. Check your state real estate commission's rules or ask a lawyer before agreeing any fee tied to a closing.

Life insurance leads

How much do life insurance leads cost?

Published ranges run from about $5 to $45 for shared web leads, $75 to $150 for exclusive leads, and $50 to over $200 for live transfers, depending on the source and the targeting.

Are exclusive life insurance leads worth the extra cost?

Sometimes. Exclusive leads usually reach the consumer more often, but whether they win depends on the agent's close rate and average premium. Compare cost per issued policy, not price per lead.

MCA leads

What are UCC leads?

Lists built from UCC-1 financing statements, the public filings lenders make when they take a security interest in a business's assets. They show a business has borrowed before, but they carry no consent to be called.

Who buys MCA leads?

Merchant cash advance funders and ISOs, the independent brokers who gather a merchant's documents and shop the deal to funders for a commission.

Solar leads

How much do solar leads cost?

ActiveProspect's published benchmarks run from under $10 for aged records to $25 to $100 for shared leads, $100 to $250 for exclusive leads and $150 to $500 for booked appointments. Prices move with location, homeownership checks and exclusivity.

Are solar appointments worth more than solar leads?

Per unit, yes, because more of the selling is done. Whether they are cheaper per install depends on the show rate, which is why installers ask for held-appointment figures rather than booked ones.

HVAC leads

How much do HVAC leads cost?

Published 2026 ranges run from $15 to $75 for shared marketplace leads, $18 to $80 per valid Local Services Ads call and $40 to $150 or more for exclusive pay-per-lead. Replacement enquiries cost more than repair calls.

Are HVAC calls better than HVAC form leads?

For repairs, usually yes, because the homeowner wants someone now and books the first company that answers. Replacement projects tolerate a slower follow-up, so form leads and booked estimates work there.
