Find the exact companies you're looking for.
Custom datasets and APIs built from Companies House financial and ownership data. Identify prospects, acquisition targets, investment opportunities and industry trends without spending hours searching manually.
Sector alone doesn't tell you who's worth calling.
Two companies with the same SIC code can be worlds apart, one thriving, one insolvent. Filtering by industry and geography gets you to the right neighbourhood, not the right company.
Assets, growth and debt tell you which one.
Balance sheet data, pre-calculated ratios and year-on-year growth separate the businesses actually worth your time from the ones just filling out a sector list.
Who owns it changes everything.
PSC ownership data shows whether a business is owner-managed, corporate-backed, or approaching a succession point. That's the difference between a cold list and the right first conversation.
This is what's left. Built to your brief, delivered in 24-48 hours.
No manual research, no sifting through Companies House PDFs. Just the companies that actually match, ready for outreach or due diligence.
