Who buys and manages Mambu inside a company?

Our Mambu list can include any of these roles.
Which Mambu products or editions can I target?
You can target accounts by the Mambu products they run, including Mambu Core Banking, Mambu Lending, Mambu Deposits, Mambu Payments and Mambu Process Orchestrator. Tell us which edition or module matters and we filter the list to those accounts.
What other software do Mambu customers use?
Mambu customers commonly also run AWS, Salesforce, Plaid, Alloy and Snowflake. Mambu is often connected to nCino, so users of those tools overlap heavily. We can filter any list by this kind of stack overlap.
What are the main alternatives to Mambu?
The main alternatives to Mambu are Thought Machine, Temenos and Finxact (Fiserv). We also keep verified user lists for Thought Machine and Temenos, which is useful for competitive displacement campaigns.
When are Mambu customers most likely to buy?
Buying triggers we track for Mambu accounts include new lending product, market expansion, core migration and funding round. A common pain point is launching products fast: lenders need quick launches.

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).
