How many companies use Teamwork?

Counts are estimates from our database and market research, so ask us for a live count for your exact criteria.
Who buys and manages Teamwork inside a company?
Teamwork is usually owned by Client Work & Agency Project Management. Decision-makers include Agency Owner / CEO, COO and Head of Delivery; Operations Manager and Resource Manager shape the choice, and Project Managers and Account Managers use it day to day. Our Teamwork list can include any of these roles.
Which Teamwork products or editions can I target?
You can target accounts by the Teamwork products they run, including Teamwork.com Deliver, Teamwork.com Grow, Teamwork.com Scale, Teamwork.com Enterprise and Teamwork Desk. Tell us which edition or module matters and we filter the list to those accounts.
What other software do Teamwork customers use?
Teamwork customers commonly also run HubSpot, Slack, Google Workspace, QuickBooks and Xero. We can filter any list by this kind of stack overlap.
What are the main alternatives to Teamwork?
The main alternatives to Teamwork are Monday.com, Asana and Productive. We also keep verified user lists for Monday.com and Asana, which is useful for competitive displacement campaigns.
When are Teamwork customers most likely to buy?
Buying triggers we track for Teamwork accounts include agency growth, PM tool consolidation, new operations leader and client portfolio expansion. A common pain point is project profitability: agencies don't know which clients make money.
Can Data InfoMetrix deliver a free sample Teamwork contact list before ordering?
Yes. Data InfoMetrix delivers a complimentary 10-record sample tailored to your target Teamwork criteria—including target job titles, company size, and region—delivered within one business day with no obligation.
How does Data InfoMetrix guarantee email deliverability for Teamwork contacts?
Data InfoMetrix provides a 99% email deliverability guarantee on all Teamwork datasets. Every contact record undergoes real-time email verification within a 30 to 45-day refresh cycle, backed by a 1:1 hard bounce replacement policy for 30 days after delivery.
Sourcing and compliance. Business contacts come from public company sources, professional directories and opt-in publishing partners, then go through SMTP verification and human review. Lists are for B2B outreach: include an unsubscribe link and honour opt-outs (CAN-SPAM), and have a lawful basis such as legitimate interest when you email people in the EU or UK (GDPR).
