After an 11-store acquisition, the truck dealer group partnered with us to deliver a post-acquisition communication program, reconnecting with thousands of individual and fleet accounts.

The Challenge

Across 11 newly integrated locations, long-standing customer relationships were eroding undetected. Post-acquisition silence was the retention risk nobody had planned for.

The Outcome

Thousands of accounts re-engaged, customer confidence restored, and operational intelligence surfaced that no financial due diligence would have uncovered.

TSX-listed junior gold company needed to reconnect with investors ahead of a new public listing. Misinformation had taken hold across their investor base. We made direct contact and the share price increased 7x within weeks.

The Challenge

Inaccurate information had circulated unchecked across a fragmented investor base, eroding confidence and engagement ahead of a new listing.

The Outcome

Direct, personalised outreach at scale corrected the narrative, restored investor confidence, and contributed to a 7x increase in share price.

Investor contact list.

When a large insurance group acquired its way across North America, 80% of inherited customers were unhappy. Nobody had called them. We did, and we changed that.

The Challenge

Customers had deep, personal relationships with their local independent brokers. Being absorbed into a large national brand, without warning or explanation, made them feel uneasy.

The Outcome

Over 10,000 direct conversations. Customers reassured that familiar staff were staying and the personal service they valued wasn't going anywhere. Frustration met head on, one call at a time.

Customers contacted.

80%+

Client & Shareholder Data Hygiene

Where real people verify what AI cannot.

A family-owned, community-driven business in the heart of Nova Scotia.

Tufford Group provides human-led contact verification and data hygiene from our operations in Halifax, Nova Scotia. We serve organisations in mining, private equity, M&A, and high-stakes B2B where the cost of a bad contact is measured in lost deals, failed raises, and broken relationships. Unlike automated data tools, our team directly contacts, cross-references, and validates each record, combining direct outreach with proprietary research methodology.

Our story

The Verification Process.

01

We validate, normalize, and deduplicate your contact data before any outreach begins.

Each engagement begins with a complete integrity review of your contact data. Every field is aligned to its correct schema, formatting is standardized across the dataset, and duplicates are reconciled record by record. Exact matches are merged, unique identifiers are preserved, and ambiguous records are flagged for verification during outreach.

Client & Shareholder Relations? Covered.

Every verified contact is a real conversation, handled by a real person.

We operate at scale without sacrificing the human judgement that makes verification meaningful.

Behind every verified record is a member of our Halifax-based team, cross-referencing data, making direct contact, and applying the kind of contextual judgement that no algorithm can replicate. When the stakes are high, whether that's a capital raise, a deal close, or a shareholder AGM, you need to know the person on the other end of your outreach is actually there.

Our team verifies thousands of contact records each month, across mining, M&A, private equity, and B2B.

$12.9M

FAQs

Human-led contact verification is the process of having real people — not automated software — confirm that contact records are accurate, current, and belong to the right person. This includes verifying email addresses, phone numbers, job titles, and company affiliations through direct outreach and cross-referenced research. Tufford Group specialises in human-led contact verification for mining companies, M&A advisors, private equity firms, and high-ticket B2B businesses where data accuracy has direct commercial consequences.
