AI-assisted B2B prospecting softwareCompanies to call. And what to say.

B2B prospecting software. You type an industry and a city ("accountants in Valencia"), OpenSells finds matching businesses with their public contact details and uses AI to prepare a brief for each call. You then organise follow-up with statuses, notes and tasks, and if you prefer, AI drafts an email for you. You make the call yourself: OpenSells does not call on your behalf.

From public sources: the business's Google Maps listing (through the Google Places API) and each company's own website. We don't sell or use purchased lists. Data may be outdated or missing: not every business publishes a phone number or email.

It is built for Spain and Spanish-speaking Latin America: you choose your country in the app, the search recognises the country or city you type, and the call brief is written in the local Spanish. The app interface is currently in Spanish only. How many companies you find depends on the industry, the city and what each business publishes.

Phone numbers often have better coverage among local businesses than useful sales email addresses and let you start a conversation directly. We still include AI email drafts, but recommend using whichever channel best fits each case.

We don't run technical mailbox verification (SMTP or MX). We extract email addresses that companies publish on their own websites, so they are public addresses, but they may be outdated or generic inboxes.

The rules depend on the country, the type of contact, the purpose and the specific circumstances: each Spanish-speaking country has its own. OpenSells works with public business data, but data being public does not on its own authorise you to contact someone for commercial purposes: how that data is used remains the user's responsibility. This is not legal advice: review your specific case and always respect requests not to be contacted again.

That's what the call brief is for. Before you dial you have what the company does, why calling them may make sense, a suggested opener, up to three questions to see whether they are a fit and prepared responses to likely objections. It is written by AI from their website and Google listing, so review it before you call.

Hunter and Apollo are broader contact-data, verification and email campaign platforms, and both also offer AI writing. OpenSells focuses on a narrower workflow: find local businesses by industry and city, gather their public data, prepare the call and organise follow-up in one place. There is a sourced comparison on the blog (in Spanish).

It only applies in Spain. Invoicing software must comply with the Spanish invoicing systems regulation (Royal Decree 1007/2023) before 1 January 2027 for corporate income tax payers and before 1 July 2027 for everyone else. There are two modes: VERI*FACTU, which sends each record to the Spanish tax agency (AEAT), and one that keeps the records in the system itself. OpenSells uses VERI*FACTU mode and includes it at no cost on every plan, free month included: upload your electronic certificate once and you can create quotes, turn them into invoices, email them and export everything for your accountant. It does not apply, for example, to businesses already on SII or taxed in the Basque Country or Navarre.

Yes, with no lock-in or penalties. Cancel from your dashboard and you will not be charged for the next billing period. The first month is free and no card is required; if you have not chosen a plan when it ends, the account switches to read-only. Within 7 days of your first charge you can request a refund under the terms of service.

It works especially well when selling to businesses with a public presence and visible contact details: repair shops, clinics, consultancies, accountants, hospitality, training or real estate, among others. It is a poorer fit if you need a specific job title inside large companies: OpenSells works with the data a business publishes, not personal profiles.

Your leads are yours. On a paid plan you can export them to CSV without a limit before cancelling. During the free trial, export is limited to 50 leads per month. We keep your history for 30 days in case you change your mind.
