Your best SaaS leads are already in your database
Vanderbuild builds B2B SaaS lead generation systems on the data you already own - product usage, billing events and CRM records, unified into one engine and activated automatically.
Data everywhere.
Your product, billing, CRM and marketing tools each hold a piece of the same customer.
None of them talk to each other, so nobody acts on what they know.
Five systems, no single truth
Payment solutions, the product itself, your CRM, external data sources, marketing tools. Each one holds a fragment of the same account, and no one on your team can see the whole record without joining them by hand.
Signals nobody acts on
A plan limit hit, a failed payment, a new seat invited. Your product records every one of these and none of them reach sales while they still mean something.
Data that costs instead of earning
You pay to store it, pay again for lists that duplicate what you already own, and it still sits there as reporting. Data should trigger the next conversation, not describe the last one.
We build your GTM engine
For a B2B SaaS company the strongest buying signal is already inside the product. Vanderbuild connects your payment system, product usage events and CRM to external sources like Clay, Apollo and LinkedIn Sales Navigator, then runs them through one engine that handles enrichment, segmentation, qualification, funneling and activation.
A failed payment or a plan limit hit stops being a line in a report and becomes the trigger for the next conversation. You own the infrastructure - we architect it, run the first campaigns, and hand over the documentation.

FAQs
Answers to the questions we hear most from B2B sales and growth leaders.
What is GTM engineering?
GTM engineering is the practice of building revenue systems instead of running campaigns by hand. Rather than hiring more SDRs, you connect the data you already own - product usage, billing events, CRM records - to enrichment and outreach tooling, then let defined rules decide who gets contacted and when. The output is infrastructure your team operates, not a retainer you keep paying for activity.
What is a product qualified lead in B2B SaaS?
A product qualified lead is an account that has shown buying intent inside your product rather than on your website. A hit plan limit, a failed payment, a new seat invited, a feature used three times in a week. These events sit in your product database and your billing system. Most SaaS companies record them and report on them monthly, but never route them to sales while they still mean something.
Should a B2B SaaS outsource outbound lead generation or build it in-house?
Build it in-house if you already have someone who can wire your product events to a CRM and an outreach tool. Most SaaS teams under 100 people do not.
How do you decide a signal actually means something for my accounts?
Scoring runs per account, not per signal. The same event means different things to different companies, so a signal is evaluated against each target account separately. Signals that name a company are matched directly. Signals about a market or a category get tagged by topic and raised as industry context, lifting buying readiness for every account in that segment. You see the scoring model before it goes live.
How much does cooperation cost?
Our lowest cooperation package starts from 1 800 USD net monthly. Most clients choose a package worth around4 500 USD net monthly. With at least 3 months of cooperation.
