Custom B2B List Building & Account Mapping Built for Your Exact ICP

No minimum — ever. We work with solo founders who need 50 contacts for a hyper-niche outreach campaign, and with enterprise sales operations that need 10,000 contacts per month. The process, the quality standards, and the sub-5% bounce guarantee are identical regardless of list size. Start as small as you need.

Most lists of 50–500 contacts are delivered within 24–48 hours of brief confirmation. Larger lists (500–5,000) typically deliver within 48–72 hours. For enterprise volume (5,000+), we scope a delivery timeline before starting. We never rush the verification step — speed never comes at the cost of accuracy.

No. Your list is delivered as a clean CSV or Excel file that works with Gmail, Outlook, or any tool you already use. If you later set up HubSpot, Salesforce, Smartlead, Instantly, or any other outbound sequencer, we format the delivery to match your import schema exactly. You don't need any existing infrastructure to get started.

After our engineering team sources the raw data from live professional networks, every single record is manually reviewed by a human specialist. We check: job title accuracy, current company status, email deliverability via real-time MX record and SMTP handshake validation, and LinkedIn profile activity. Records that fail any check are replaced before the file is sent to you. This is what keeps our bounce rate below 5% — not software alone.

Any contact that bounces or doesn't precisely match your ICP criteria is replaced for free within 24 hours. No escalation process, no lengthy dispute — you flag it, we replace it. This policy has been in place since 2013. It also means you never pay for bad data: our post-delivery payment model means you review the complete dataset before payment is due.

Yes. All contacts are sourced from publicly accessible professional identifiers — corporate registries, verified public business networks, and professional announcements. We never mine private databases, purchase scraped dumps, or access closed data sources. Every dataset includes sourcing context so your legal team can review the basis for processing if required.

Those platforms sell access to a static database — records that were verified weeks or months ago. People change jobs every 18 months on average, which is why Apollo and ZoomInfo lists typically produce 15–25% bounce rates. We don't have a database to resell you. We build your list from scratch against your exact brief, then verify every email at the hour of delivery. You also don't pay a monthly subscription — you pay per project, after reviewing the data. For any team running precision outbound, the cost difference is irrelevant compared to the domain reputation damage a 20% bounce rate causes.

Yes — this is one of the most-requested additions to standard list builds. We can map the entire decision-making unit for each target account: C-suite sign-offs, Director-level end-users, RevOps gatekeepers, and champion-level influencers. Multi-contact mapping is available on any list size and uses the same 12-field standard format as a single-contact list.
