FAQ
Everything You’re Wondering (We’ve Heard It Before)
What services does Lead Assassin offer?
Lead Assassin builds advanced Clay systems to streamline Outbound, Inbound, and Revenue Operations. We design, deploy, and optimize workflows that automate GTM motions so your pipeline runs faster, cleaner, and on autopilot.
Why should I choose Lead Assassin over other service provider?
You don’t have to choose us, and that’s okay. At the end of the day, the right agency is the one that aligns with your specific needs and goals. While we could talk about how great we are, we believe the best way to know if we’re the right fit is to have a conversation. Simply book a call, and let’s find out together.
What type of clients do you work with?
We work with a wide range of B2B businesses. Most of our clients are startups and service providers in the B2B space especially those in software, web development, and tech-enabled services.
What is Clay, and why should I use it?
Clay is a platform that connects with 100+ tools to help you build smarter GTM workflows. It automates manual tasks like list building, enrichment, and research—so you or your team can save time and focus on high-impact work. As GTM teams face increasing pressure to move faster in 2025, Clay empowers them to streamline operations, reduce busywork, and drive better outcomes across the funnel.
How is your service different from hiring an in-house team or freelancer?
We’re not here to “fill a seat.” Our team brings years of GTM and Clay-specific experience, with 80+ systems deployed across startups and scaling B2B teams. You’re not hiring a junior or someone learning on the job—you’re getting proven operators who’ve seen what works (and what doesn’t).
What tools do you work with besides Clay?
While Clay is our core, we work with a stack of tools to power full-funnel automation—including n8n, Instantly, HeyReach, Zapier, Make, and HubSpot. If there’s a better or faster way to move data, enrich leads, or trigger actions, we’ll find it and wire it up..
Can you integrate your workflows with our existing CRM or tools?
Yes. Most of the systems we build are designed to sync with CRMs, outbound tools, and internal dashboards. We use automation platforms like OutboundSync, n8n, Zapier and Clay to make sure everything plays nicely together—without creating a mess.
Do you offer guaranteed results?
No. Success depends on several factors outside our control—such as your offer, timing, market conditions, and competitive landscape. What we do guarantee is that we will build the best possible system to set you up for success.
No one can guarantee business results. Even the most expensive consultants and agencies cannot promise a specific revenue outcome, because too many variables are outside anyone’s control.
What kind of results can I expect?
We don’t promise magic, but we do promise motion. You can expect faster lead routing, more qualified accounts and leads, cleaner data, and smoother handoffs across your sales team. The actual numbers? That depends on your offer, list, and goals—but we’ve helped teams 3x reply rates, double qualified demos, and save hundreds of hours with the right systems in place..
Can you train our team to manage Clay internally?
Yes! If you prefer to keep things in-house, we offer Clay training sessions for founders, marketers, and sales ops teams. We’ll teach your team how to think like a GTM engineer—so you can scale what we build or even clone it across other segments.
