Lead Generation
AI qualification, lead management, and conversion tools for lead gen businesses
Lead gen businesses live or die on data quality and speed-to-contact. We build systems that qualify leads automatically, route them instantly, and integrate with every platform in your stack so your team calls the right people first.
Nub Labs builds custom AI voice agents and lead qualification systems for lead generation businesses. Our voice agents call new leads within seconds of capture, ask your qualifying questions, score intent in real time, and route hot leads instantly to the right rep or book them straight into a calendar. Because speed-to-lead decides conversion, our agents run inbound and outbound campaigns around the clock without adding staff. We build on Vapi, Retell AI, Twilio, and ElevenLabs, and integrate with every platform in a typical lead gen stack - CRMs, dialers, and data sources - so leads are aggregated, qualified, and actioned automatically. Every call produces a structured record with transcript and outcome pushed to your CRM. Lead gen clients use our systems to raise contact and conversion rates and stop losing leads to slow follow-up. Engagements begin with a free 30-minute scoping call and a fixed-price quote.

FAQ
Common questions
How fast can an AI voice agent call a new lead?
Immediately — within seconds of the lead submission. We trigger the AI voice agent via webhook as soon as a lead arrives, so the first contact happens before a human rep has even seen the notification. Speed-to-contact is one of the highest-leverage variables in lead gen conversion rates.
Can you build a system that deduplicates leads across multiple sources?
Yes. We build deduplication pipelines that match leads across email, phone, and name using fuzzy matching and phone number normalisation. Duplicates are flagged or merged automatically before they enter your CRM.
How do you handle lead routing across multiple sales reps or buyers?
We build routing logic based on your rules: geography, lead type, rep capacity, buyer contracts, or lead score. Routing happens in real time on lead arrival, with fallback rules when the primary assignee is unavailable.
What lead source integrations do you support?
We integrate with every major lead source - Facebook Lead Ads, Google Ads, landing page forms, affiliate networks, ping-post systems, and inbound call platforms. Data is normalised and routed through a central pipeline regardless of source format.
Can you track which lead sources generate the highest-quality conversions?
Yes. We build attribution pipelines that close the loop from lead source through qualification, sale, and lifetime value. You get a view of cost-per-qualified-lead and cost-per-sale by source, not just cost-per-lead - which is the metric that actually drives budget decisions.
