Yes. Security is taken seriously at OneSales.

We connect via secure OAuth or API token authentication. All data is encrypted in transit and at rest. We read what we need to generate intelligence and do not store your CRM data permanently. Your data is never shared with other customers and is never used to train shared AI models.

We comply with GDPR and UK data protection requirements. Full details are at onesales.ai/privacy. Security documentation is available on request at sales@onesales.ai. We are happy to help you evaluate fit for your team and workflow.

OneSales does the account research work that currently slows your team down.

For every target account, it builds a company overview, assesses fit against your ICP, maps the buying team including contacts your CRM is missing, tracks relevant signals, and generates a personalised outreach email. Your rep opens OneSales instead of spending an hour across five different tools. Everything they need is already there. We are happy to help you evaluate fit for your team and workflow.

OneSales automates account research for B2B sales teams. We build a profile of your company, your ICP, and your messaging. Then we build a profile of each of your target accounts.

For every account, your rep gets a company overview, an account fit assessment, a complete buying team map, and all the signals that matter. News, LinkedIn activity, funding rounds, earnings, champion job moves, and competitive intel.

Your reps stop spending hours researching and start showing up to every conversation fully prepared. If you would like to discuss your specific requirements, we can walk you through the best approach for your team.

OneSales is registered in England and Wales. Our founding team spans San Francisco and Prague, and we support customers across the US, UK, and Europe.

For any questions about our location or operations, reach out at hello@onesales.ai. We are happy to help you evaluate fit for your team and workflow.

OneSales is built for enterprise B2B revenue teams who need to know more about their accounts before they engage.

That includes Account Executives managing complex deals across multiple stakeholders, SDRs and BDRs running outbound who need a genuine reason to reach out, Customer Success teams managing renewals and expansion, and Revenue Leaders including CROs and RevOps who want their team operating with consistent, high-quality account intelligence. We are happy to help you evaluate fit for your team and workflow.

OneSales was founded by Seamus Devine and Jiri Zajpt.

Seamus has been in enterprise software and sales since 1995 and previously founded ClosePlan, a sales execution platform that was acquired by People.ai. Jiri has over 20 years of engineering experience and previously founded Blueberry Apps, a software development firm based in Prague.

Both founders have spent their careers close to the problems OneSales solves. The platform is built by people who have lived the pain of manual account research, incomplete buying team visibility, and missed signals. If you would like to discuss your specific requirements, we can walk you through the best approach for your team.
