The problem
You bought the tools. Pipeline still depends on reps grinding through manual research, data rots in the CRM, and every dashboard says everything is fine.
The gap between owning tools and running systems is where I work, mostly with Series A to B B2B teams running outbound. See what CRM decay costs you →

The shape of every system I ship: your data in, enriched and scored, routed to where your team already works.
A scoping sprint. I reverse-engineer your ICP from closed-won deals, map the channel mix, and design the offer. We leave with a build plan, not a slide deck.
One system shipped end to end: enrichment, signals, or CRM automation. You watch it run on real data before we scale it.
Sequenced outbound, reply routing, monthly iteration. Everything documented, owned by you, and running without me.
Projects start at $6K and ship one scoped project. Quarterly retainers are $25K and cover as many projects as we can ship together inside the 90 days. More in the FAQ ↓
Certified Clay Partner · Clay Bootcamp TA · 10 years B2B sales About
I'm Willy Hernandez. I spent 10 years carrying a quota. Cold calls, discovery, forecasting, the whole loop. I know exactly what it feels like when pipeline dries up and the tools just sit there looking expensive.
A few years ago I started asking a different question: what if I could build the system instead of just use it? So I learned to code. Now I ship automations that run around the clock without me touching them, because that is where GTM is going, and reps deserve tools that reflect it.
FAQ
Thirty minutes. You tell me what's broken in your motion. I ask the kind of questions a senior AE would ask if they were running discovery on your business. By the end we either have a clear scope or we don't. Both outcomes are fine.
Same week if we're aligned on scope. I take one or two new builds a quarter so I can stay deep on each one. If I'm full, I'll tell you in the first email.
Two paths. Projects start at $6K and ship one scoped project end-to-end. Quarterly retainers are $25K and cover as many projects as we can ship together inside the 90 days.
HubSpot, Salesforce, Clarify, Attio. If you run it, I integrate to it. If you're shopping for one, I'll tell you which I'd pick for your motion and why.
Depends on what's broken. One fintech client went from a signed SOW to six production signals firing in HubSpot and Slack within two weeks. An L&D software company got 7,255 companies enriched and validated to 96.7% coverage in a single run. I don't promise numbers I can't back up with a working system.
Everything I build is documented, owned by you, and runs without me. Video walkthroughs of every system, runbooks for every workflow, full handoff to whoever picks it up.
