A better brief.
A more useful shortlist.

Find new companies, or understand the ones you already have.

Start with a small, coherent audience. “UK homeware stores using Shopify” gives a clearer brief than “any business that might need marketing.” Add exclusions for customers, competitors and companies already in your pipeline.

Separate hard requirements from useful context.

A requirement can be a named technology, a public business clue, or a condition that needs checking. Search the catalogue, combine selections, or describe a custom requirement. Exclusions help clarify the audience and do not add a separate signal charge.

We keep the selected All/Any rule in your brief. We do not silently broaden it to fill a quantity. A custom description counts as one requirement in your price; we research it as written after payment.

Keep business context clear

A company website is a useful starting point, but its domain does not establish where the business operates. If your offer depends on a particular market, explain that context in your brief. Country and domain-ending controls are hidden at launch; the builder focuses on technology requirements and research depth.

3,632 ways to describe your audience.

The main selector contains 1,000 ranked web technologies. The full list adds 2,586 more technologies, for 3,586 measured technologies in total. Another 46 tools, business criteria and email-authentication conditions bring the complete catalogue to 3,632 options. The technology ranking uses HTTP Archive’s mobile-origin adoption snapshot from 1 August 2026. It includes libraries and web standards as well as commercial tools.

This is a research and targeting menu. It is not an inventory count, a ranking of every internal business system, or a claim that every option has a live detector. 71 options have an existing public-clue definition; the other 3,561 are research requests. Availability, evidence and company attribution are checked for the accepted scope.

Website observations are time-bound and incomplete. A job advertisement mentioning Python is different from a live website fingerprint. A payment script can support a Stripe observation without proving Stripe Connect. Missing DMARC and a published policy of p=none are different conditions. An unknown result does not prove absence.

The same audience. Three levels of understanding.

Dossiers follow the useful evidence available. They do not fill a promised word count with generic prose. Switch between the three sample views to see the distinction.

A score should explain itself.

Fit measures the match to your agreed criteria. It is not a probability that a prospect will buy. A useful record carries the score rubric, sources, observation dates and coverage gaps so you can understand why it earned its place.

• Observed: a directly recorded public clue, with its source.
• Claimed: a company or another source says something; the attribution remains visible.
• Inferred: a supported interpretation that still needs confirmation.
• Unknown: the available evidence did not establish the field.

For new leads, a generic inbox alone does not meet the named-contact requirement. One person appearing twice does not create two companies. Phone numbers are included only where available. Published email evidence does not guarantee inbox placement, replies, or continued employment.

The operator reports an average of approximately 2.3 email addresses per new lead. This is not an independently measured performance claim or a minimum per record. The new-lead requirement remains at least one attributed named administrator/founder email.

Keep the rows. Add the context.

Paste domains or upload CSV/TXT. A CSV may use a domain, website, URL, company_website, or company domain column. The builder shows invalid values for correction and counts distinct valid company domains for pricing.

Download the company-list template and replace its fictional example rows before uploading. CSV/TXT files may be up to 2 MB.

Duplicates count once, while original rows and source identifiers are preserved for a matched return. Up to 50,000 source rows are supported within the displayed upload limit. Supplying 140 unique companies means 140 billable companies; a list below 100 has a 100-company minimum charge.

Only include data appropriate to business research. Remove private notes and unnecessary personal data. Enrichment can leave fields unknown and does not guarantee finding a new named email for every supplied row. Download the synthetic CSV to inspect a possible return format.

Tell us what a good fit looks like.

Your-offer intelligence needs your company website plus either an offer URL or a brief. Include what you sell, who benefits, relevant territory, decision roles, disqualifiers and any constraints that are missing from the public website.

Paste text or upload PDF, TXT or DOCX up to 3 MB. The combined brief is limited to 3,000 words. Uploaded files are sent for text extraction; you can review the extracted text before submitting the order. For a scanned PDF without readable text, paste the useful content instead.

Download the Word or text offer-brief template for prompts covering fit criteria, exclusions, territory and contact roles. A PDF reference is also available.

An estimate you can follow.

With one requirement, 100 new companies cost $19 for Stack leads, $39 for Company intelligence, or $79 for Your-offer intelligence. Each additional selected requirement adds $0.10 per company, including with Match any. No subscription or automatic volume discount applies. See all rates and worked examples.

Delivery by email

The agreed CSV and supporting evidence or dossiers are delivered to the email address supplied with your order. They arrive as attachments, or through a private download link in the email when files are large. The selected tier and accepted scope determine the contents.

Delivery windows

Exactly 1,000 belongs to the 24-hour band; exactly 10,000 belongs to the 7-day band. The builder supports up to 50,000 companies. You pay at secure checkout, and the window starts once payment is confirmed.

Build, pay, receive.

1. Build: select companies, requirements, depth and quantity. Review the price.
2. Submit: provide contact details. We save your order and give you a reference.
3. Pay: you go straight to Stripe’s secure checkout. Only Stripe’s payment confirmation marks an order paid; a browser return page is not payment verification.
4. Prepare: after payment, we research your list against the specification you ordered. If part of it cannot be delivered as specified, we contact you to agree a change or other resolution rather than silently relaxing it.
5. Receive: receive the records and research by email, with sources, gaps and the specification you ordered.

If a submission times out, it may have been received. Retry the same request or contact support before creating another, so you are not charged twice. Chat cannot inspect private orders or confirm a payment.

Use the evidence to ask a better question.

Open with a relevant business observation and explain why you are reaching out. Treat a suggested angle as a starting point to review. A visible technology does not prove a problem, budget, or buying intent.

Use data lawfully for the recipient and jurisdiction. Identify yourself, honor objections, and suppress opted-out people in future campaigns. Coordinate contacts at the same company: multiple addresses are choices, not a reason to repeatedly message everyone. Do not use this service for sensitive personal profiling or decisions about employment, credit, housing or other eligibility.
