Custom Software for B2B Lead Generation
In short
B2B teams rent lead databases and enrichment tools billed per credit and per seat — renting access to data they never keep. We build lead engines you own: discovery, verification and outreach running autonomously on your own infrastructure.
What you're renting
B2B lead-gen runs on rented data — a lead database per seat, enrichment billed per credit, and outreach tools with sending caps. You pay for access but never own the list or the system, and the cost scales with every prospect you touch.
What we'd build you to own
- An owned lead engine that discovers and verifies prospects at scale — like the OSS Apollo Lead Engine: 38K businesses, 56K verified emails, running autonomously via systemd.
- Enrichment and verification on your own data, with no per-credit metering.
- Outreach and sequencing you control end to end.
- Pipelines that run themselves on infrastructure you own.

Frequently asked questions
What does a custom B2B lead-generation system include?
Prospect discovery, email verification, enrichment and autonomous outreach — built as software you own rather than data you rent per credit. For one team we built the OSS Apollo Lead Engine: 38,000 businesses and 56,000 verified emails, running autonomously via systemd.
Is owned lead-gen software better than a lead database subscription?
When lead generation is core to your pipeline and you're paying per seat and per credit, an owned engine removes the metering and keeps the data — the list and the system are yours. For occasional, small-volume needs a subscription is simpler; owning pays off at scale.
Do I keep the leads and the system you build?
Yes — the data, the verification logic and the outreach system are all yours, running on your own infrastructure. No per-credit fees and no vendor that can revoke access to your own pipeline.
