Business application
LeadBloom
Cold outreach. Warm replies.
LeadBloom is a Windows application that takes you from an empty list to a sales conversation: it finds companies, checks them in official registries, fills in contact details, helps you write personalized messages, sends them from your own mailbox, and organizes the replies in a CRM. Your data stays on your computer.
Windows 10 (version 1903 or later) and Windows 11
Key capabilities
- Companies from registries, directories, maps, and search engines
- Data confirmed in official Polish registries and EU VIES
- AI-written cold email campaigns that you approve
- Reply inbox and CRM in the same application
Sourcing
A list of companies from your industry and region
Enter keywords or choose PKD codes, a country, and a region. LeadBloom searches the CEIDG registry, industry directories, OpenStreetMap, and search engines, and later runs skip the companies you already have.
- 29 search countries, each with a legal risk rating and the available registries
- Search through your own Chrome in 10 search engines — with no CAPTCHA bypassing
- AI sourcing with a DNS check of every address and costs visible as you go
Verification
Data confirmed in official registries
One button queries the VAT White List, KRS, CEIDG, GUS, and VIES. Results from several registries are merged, and every field shows its source and date — a green value is confirmed in a registry.
- Revenue and net profit from financial statements filed in KRS
- Differences between the company website and the registry shown as a separate result
- AI estimates marked “≈” — they never overwrite registry data
Campaigns
AI-written messages that don't make things up
Describe your company and offer, choose a style and tone, and AI writes a separate email for each recipient. Validation holds back emails with empty variables, emails missing the GDPR notice or unsubscribe link, and emails with figures or claims that aren't in your data.
- Up to 5 steps: the main email and follow-ups in the same thread
- The model never sees the recipient's email address
- Offer details can be filled in by AI from your website or a file
Sending
Nothing goes out without your approval
You review every email in the approval queue next to the company data. Approved messages leave your mailbox in batches — on the days and at the hours you choose, with a daily limit and a random interval between emails.
- Suppression list, limits, and time window checked again before every email
- A reply from the recipient stops their sequence
- An out-of-office reply moves the next step to the day after the recipient returns
Inbox and CRM
From reply to won opportunity
Replies fetched over IMAP land in the inbox with a recognized category: interested, not now, no, someone else, unsubscribe, or bounce. One click turns a conversation into a sales opportunity that you move through the pipeline until it is won.
- Tasks with due dates, reminders, and a list of opportunities idle for 14 days
- AI analysis of up to 20 opportunities at once
- Mail fetched in read-only mode — messages are not marked as read
Deliverability and compliance
Protects your sender reputation and keeps to the rules
LeadBloom checks SPF, DKIM, and DMARC, sends a test email, and — if you want — warms up the mailbox. After a hard bounce, the address goes onto the suppression list automatically, and the campaign pauses when there are too many bounces.
- Legal risk rating for 35 countries, with the legal basis and the supervisory authority
- A GDPR Article 14 notice and an unsubscribe link in every email
- Deliberately no open or click tracking
Features
Sourcing from many channels
The CEIDG registry, industry directories, OpenStreetMap, search engines through your own Chrome, and an AI model — all in one database, with no duplicates.
Registry verification
VAT White List, KRS with financial statements, CEIDG, GUS, and VIES behind one button; a green value is confirmed in a registry.
The origin of every field
For every value, you see whether it came from an official registry, the company website, AI, or manual entry — and when it was retrieved.
AI-written campaigns
A separate email for each recipient, based on the company data and your offer; validation stops invented facts and empty variables.
Approval and batch sending
You approve emails with the A and R keys, and the program sends them from your mailbox within a time window, 90–180 s apart at random.
Inbox and CRM
Replies with a recognized category — interested, not now, bounce — and sales opportunities with tasks and reminders.

Full feature list
Dashboard
- Alerts with fixes – expired keys, search engine blocks, and sending errors — every alert has a button that leads to the solution.
- Database status – number of companies, companies with email and phone, addresses in the Website database, and records without a tax ID; a click opens the right tab.
- CRM and AI costs – today's and overdue tasks, opportunities without a next step, and AI costs by provider and model.
Company sourcing
- New search – keywords, multiple PKD codes (PKD 2007 tree, 1,652 entries), country, region, city, and a limit of up to 10,000 results.
- Candidate sources – the CEIDG registry, industry directories in 7 countries, DuckDuckGo, OpenStreetMap, your own SearXNG instance, and 10 search providers with your key; a free-only mode is on by default.
- Run modes – search only, breadth crawl, depth crawl, or full — with depth 0–5 and 1 to 32 parallel downloads.
- Search through Chrome – the extension uses your own Chrome in 10 search engines at three work paces; when asked “are you human,” the run waits for you.
- Import from the browser – paste a whole Google or Bing results page, and the program discards ads, search engine links, and social profiles.
- AI sourcing – a series of narrow keyword × city queries, five geographic scopes, a DNS check of every address, and costs visible as you go.
- Check sources – a test of which source works, fails, or is blocked, plus firewall and antivirus advice.
Databases
- Website database and Company database – everything found goes into the Website database; records move to the Company database only when you decide.
- 30 color-coded columns – a green value — confirmed in a registry, a red row — another company's tax ID, a yellow row — three unsuccessful enrichment attempts.
- Filters across the whole database – search with “or,” country, source, missing tax ID, date range, missing columns, and narrowing to a single run.
- Import and paste – CSV, TSV, TXT, XLSX, XLSM, and JSON files with column detection in 6 languages, or a pasted list of tax IDs and addresses with a preview.
Enrichment and verification
- Fill in data – the crawler collects NIP, REGON, and KRS numbers, emails and phone numbers with the person and job title, social profiles, and keywords; it reads structured data and hidden email addresses.
- Confirm in registries – VAT White List (batches of 30 tax IDs), KRS with share capital and financial statements, CEIDG, GUS BIR1, and VIES — results merged with a priority for each field.
- AI enrichment – the model fills in selected columns and finds website addresses; values are validated and never overwrite registry data.
- Estimated annual revenue – the figure from a KRS financial statement or an AI estimate marked “≈,” converted into your chosen currency at ECB rates.
Company card and mailing lists
- 22 fields with an origin marker – registry, financial statement, company website, AI estimate, manual entry, or import; a manual edit locks the field against automatic overwrites.
- Contacts and history – people with their role and department, addresses, a comparison with the registry, change history, and sales opportunities.
- Mailing lists – generic addresses only, named addresses only, or a full list; addresses on the suppression list are always skipped.
Campaigns
- Three content modes – the same content for everyone, a separate subject and body for each step, or an email written by AI for each recipient.
- Up to 5 steps – the main email and follow-ups 1 to 60 days apart, sent in the same thread.
- AI instructions – 5 styles, 4 tones, form of address, 9 email languages, and 6 length ranges — which you can save as a template.
- Company and offer details – 9 fields: company, offer, target audience, strengths, proof, pricing, your ask, links, and what not to write; AI can fill them in from your website or a file.
- Content safety – no invented facts or prices, links only from your list, and emails with empty variables or without the GDPR notice and unsubscribe link are blocked.
- Sending schedule – days of the week and hours, a daily limit per mailbox and per batch, skipping public holidays, and an automatic start in the sending window.
- Duplicate protection – when an address is already in another campaign, the program asks whether to add only new addresses, all of them, or move them.
Inbox and CRM
- Inbox with categories – bounces, out-of-office replies with a return date, and replies: interested, not now, no, someone else, unsubscribe — you can correct the category by hand.
- 18 ready-made mailbox profiles – including Gmail/Workspace, Outlook/Microsoft 365, OVH, Zoho, Yahoo, iCloud, GMX, Fastmail, and your own server, plus popular Polish providers; app passwords stored encrypted.
- Sales pipeline – Reply → Conversation → Offer → Won or Lost; only a person changes the stage.
- Tasks and AI analysis – today's tasks, reminders with sound, idle opportunities, and analysis of up to 20 opportunities at once, with recommendations saved in the history.
Statistics and deliverability
- Email statistics – sent, delivered, bounces, replies from people, unsubscribes, and complaints — counted per unique address, with a daily chart.
- DNS and delivery test – SPF, DKIM, and DMARC check and a test send that reads whether the email landed in the Inbox or in spam.
- Mailbox warm-up – optionally 5, 10, 15, and 20 emails a day in the following weeks, then gradually up to the target limit.
- Safety limits and bounce automation – a campaign pauses when there are too many bounces or complaints, and an address is suppressed automatically after a hard bounce.
Artificial intelligence
- API providers – OpenAI (ChatGPT), Anthropic (Claude), Google (Gemini), Perplexity, and DeepSeek — each with its own keys, price list, and balance.
- Browser mode without a key – questions go to your logged-in chat in ChatGPT, Claude, Gemini, Perplexity, DeepSeek, or Microsoft Copilot, with no token bill.
- Task and Improve prompt – series of prompts with attachments, a cost estimate before sending, image and SVG generation, and prompt refinement.
- History and costs – every query with tokens, cost, time, and error, and a cost chart by model.
Legal compliance
- Suppression list – an email address, domain, or tax ID, stored as a salted SHA-256 hash; entries come from unsubscribe links, replies, the API, and bounces.
- Country risk – a classification of 35 countries with the legal basis, consent model, penalties, and supervisory authority; a high-risk country must be unlocked with a code.
- Pre-send gate – suppression list, legal basis for named addresses, country risk, and the information obligation checked before sending.
- A polite crawler – an open User-Agent, 1 request per second per server, robots.txt according to each country's policy, and no logins, CAPTCHAs, or paywalls.
Export and integrations
- Export – CSV, XLSX, and JSON with a choice of rows and columns and protection against formula injection into spreadsheets.
- API v1 – keys with scopes (companies, campaign sending, suppression list), rate limiting, and idempotency.
- Webhooks – 7 events signed with HMAC, up to 5 delivery attempts, and automatic disabling after a series of errors.
Settings and security
- Six interface languages – Polish, English, German, French, Spanish, and Italian — the change takes effect immediately, without a restart.
- Appearance – 22 color schemes, including high contrast, scaling from 25% to 200%, and a basic and an advanced mode.
- Accounts and roles – up to 5 users (administrator, operator, viewer), protection against password guessing, optional 2FA (TOTP), and an activity log.
- Keys and secrets – API keys are encrypted and only the last 4 characters are shown; the internal server listens only on 127.0.0.1.
About the application
LeadBloom is a desktop application for Windows 10 and 11 built for B2B prospecting. It brings company search, verification in official registries, contact enrichment, AI-assisted cold email campaigns, reply handling, and a simple CRM together in one program. It runs locally — no cloud and no paid contact database — and email goes out from your own mailbox.
How it works
- Find companies — by keywords, industry codes (Polish PKD), and region: in the CEIDG business registry, industry directories, OpenStreetMap, search engines, and with the help of an AI model. You can also paste a list of tax IDs (NIP) or website addresses, or import a file.
- Check them in registries — the Polish VAT White List, KRS (including revenue and net profit from financial statements), CEIDG, GUS, and the EU VIES system. Every field keeps its source and date.
- Fill in contacts — a crawler visits the company website and its subpages and collects email addresses and phone numbers, along with the person, job title, and department.
- Prepare a campaign — up to 5 steps (an email plus follow-ups), with content from a template or written by AI separately for each recipient.
- Approve and send — you approve every message in a queue, and sending happens in batches from your mailbox, on the days and at the hours you choose.
- Run the conversations — replies land in the inbox with a recognized category, and one click turns a conversation into a sales opportunity in the CRM.
Three principles the program is built on
- The official registry comes first. An estimate, such as one from AI, never pretends to be a fact — it is marked with “≈” and never overwrites registry data.
- No message leaves without human approval.
- The suppression list overrides everything, including the administrator — the program checks it when building a mailing list and again right before sending.
One program instead of several services
| Task | Usually | In LeadBloom |
|---|---|---|
| List of companies by industry and region | a paid contact database | CEIDG registry, directories, OpenStreetMap, search engines, and AI |
| Checking a business partner | manual lookups in several registries | one button: VAT White List, KRS, CEIDG, GUS, VIES |
| Email addresses and phone numbers | a separate contact-finder tool | a crawler for company websites |
| Cold email campaign | a mailing tool | campaigns of up to 5 steps sent from your own mailbox |
| Sender reputation | a separate mailbox warm-up service | SPF/DKIM/DMARC check, warm-up, and campaign safety limits |
| Replies and sales | a separate CRM | inbox and sales pipeline in the same window |
Who it is for
For salespeople, small business owners, lead generation agencies, and B2B sales teams (up to 5 user accounts with roles) who want to build their own prospect lists and run outreach without subscriptions to contact databases and mailing tools.
Search covers 29 countries (the European Union, the United Kingdom, and the USA). The official registries built into the program are Polish; VAT numbers from other EU countries are checked in VIES.

Gross prices include Polish VAT. For businesses and customers from other countries VAT is calculated in the order summary (e.g. reverse charge in the EU, 0% outside the EU).
The price shown here is an estimate: we convert from PLN using the National Bank of Poland's exchange rate and round up. Your invoice and any payment you make are always processed in PLN - your card issuer or bank handles the actual conversion, and may apply its own rate or fees.
A one-off license is granted for an indefinite period: the application works for as long as we run the service and the license server. You are buying a license to use the application, not ownership of it. Details: Terms of sale, § 9.

Questions about LeadBloom
What is LeadBloom?
LeadBloom is a Windows 10 and 11 application for B2B prospecting. In one window, it finds companies, checks them in official registries, fills in contact details, prepares AI-assisted cold email campaigns, sends them from your own mailbox, and organizes the replies in a CRM.
Where does LeadBloom get company data from?
From public sources: the CEIDG registry, industry directories (in 7 countries), OpenStreetMap, search engines (including through your own Chrome), the companies' own websites, and — if you want — an AI model. You confirm the data in the Polish VAT White List, KRS, CEIDG, GUS, and the EU VIES system. Every field shows where it came from and when it was retrieved.
Do I have to pay for a contact database or a sending tool?
No. LeadBloom does not use a paid contact database — you build the list yourself from public sources — and email is sent from your own mailbox (for example Gmail, Outlook/Microsoft 365, OVH, Zoho, or your own server). By default, only free search sources are used; you connect paid search and AI providers with your own key only if you want to.
Are messages sent automatically?
No. No message leaves without human approval. You review every email in the approval queue (A to approve, R to reject), and approved emails are sent in batches according to the schedule you set.
Can the AI invent things about my offer or the recipient?
The program limits this on several levels: a ban on inventing facts, prices, and past cooperation (it can't be switched off), links taken only from the “Links” field, and validation that detects figures and claims not found in your data and holds such an email in the queue with the reason. The model also never sees the recipient's email address.
Can I use AI without an API key?
Yes. In browser mode, the Chrome extension types the questions into a chat window where you are logged in (ChatGPT, Claude, Gemini, Perplexity, DeepSeek, or Microsoft Copilot), so you don't pay for tokens. You can also connect your own OpenAI, Anthropic, Google, Perplexity, or DeepSeek API keys — the cost of every query is shown in the history.
Where is my data stored?
On your computer — in a local database and files in the LeadBloom folder in your user profile. The program has no cloud to which it would upload your company database. Internet connections are used for searching, querying registries, sending and receiving email, the AI providers you choose, and license verification.
Does LeadBloom help with GDPR compliance?
Compliance mechanisms are built into how the program works: an overriding suppression list (checked when building a list and right before sending), a GDPR Article 14 notice and an unsubscribe link in every email, a required legal basis for named addresses, a legal risk rating of the recipient's country, and no open or click tracking. The sender remains responsible for the content and legality of a campaign — the program does not replace legal advice.
Does LeadBloom work outside Poland?
Search covers 29 countries: the European Union, the United Kingdom, and the USA, and each country shows a legal risk rating. The official registries built into the program are Polish (VAT White List, KRS, CEIDG, GUS); VAT numbers from other EU countries are checked in VIES. The interface is available in Polish, English, German, French, Spanish, and Italian, and the AI writes emails in 9 languages.
Do I need Google Chrome?
Yes. Chrome is required for browser search, AI browser mode, and saving script-rendered pages. You install the extension from within the application — the program copies the files and guides you step by step.
Won't sending hurt my mailbox's reputation?
LeadBloom has several safeguards: an SPF, DKIM, and DMARC check, a test send, optional mailbox warm-up, a random interval of 90–180 s between emails, daily limits, and an automatic campaign pause when there are too many bounces (by default from 5% hard bounces). An address that hard-bounced goes onto the suppression list.
Can I import my own database and export it?
Yes. Import supports CSV, TSV, TXT, XLSX, XLSM, and JSON files (columns detected by the header in 6 languages or by the content), and export supports CSV, XLSX, and JSON. You can also pass data to other systems through API v1 and HMAC-signed webhooks.
How many people can work in the program?
Up to 5 user accounts with roles: administrator, operator, and viewer. Accounts are protected against password guessing and offer optional two-factor sign-in (TOTP) and an activity log.
What are the system requirements?
Windows 10 (version 1903 or later) or Windows 11, Google Chrome, and an internet connection. The installer works for a single user, without administrator rights. Optionally, you can add free official GUS BIR1 and CEIDG keys and keys from search and AI providers — the program also works without them, with a smaller set of sources.
Which purchase options are available?
A one-time license or a prepaid subscription — monthly or annual, with no automatic card charges. You'll find the prices of each plan in the price list on this page.
