Frequently asked questions
Why build custom lead generation software instead of using HubSpot or Salesforce?
Custom software gives you a proprietary edge, eliminates expensive per-seat licensing fees, and fits your exact unique marketing funnel rather than forcing you to adapt to a generic tool.
Can you integrate the software with our existing tools?
Yes. We build robust API integrations to connect your new lead generation platform with your existing ERP, accounting software, or legacy CRM.
Is the lead capture process compliant with data privacy laws?
Absolutely. We design all lead generation software with GDPR, CCPA, and other relevant privacy regulations in mind, including consent management and data security.
Can you automate email and SMS outreach?
Yes. We integrate providers like Twilio, SendGrid, and Mailgun directly into your platform for seamless, automated multi-channel follow-ups.
How long does it take to build a custom lead generation platform?
A targeted lead capture tool can be launched in 4–8 weeks. A comprehensive marketing and CRM platform typically takes 8–14 weeks depending on the complexity of integrations and automated workflows.
