What ICP List Builder is
You know who your best customers are. The problem is turning that knowledge into a clean prospect list every week. ICP List Builder does it for you: it pulls companies and contacts that match your ideal customer profile (ICP) from tools like Apollo and Clay, removes duplicates, checks the data, and delivers a ready-to-use list on whatever schedule you set.
If your team spends too much time pulling names out of LinkedIn and spreadsheets instead of actually reaching out, this is built for you. You define the criteria, and the agent handles the rest.
Who it is for
ICP List Builder is a good fit for any team where list quality makes or breaks outbound. That usually looks like:
- Sales development reps (SDRs) who build account lists every week and need to move faster without cutting corners on quality.
- Revenue operations leaders who want to make sure only the right accounts get into outbound sequences.
- Founders running lean outbound who can't afford to waste time chasing companies that were never going to buy.
What problems it solves
When your prospect list is off, everything that follows suffers. Outreach falls flat, reps burn hours on the wrong accounts, and the whole team starts to question whether outbound even works.
- List building is scattered across Apollo, LinkedIn, spreadsheets, and whatever your last rep happened to use.
- Your ICP criteria exist in a slide deck somewhere, but nobody actually follows them day to day.
- Every rep builds their own list differently, so quality and coverage are all over the place.
- Lists go stale because nobody has time to refresh them as companies grow, change, or stop being relevant.
How it works
ICP List Builder puts together, checks, and refreshes your prospect lists based on who you actually want to sell to.
- Set your criteria: Tell it what a good-fit account looks like: industry, company size, revenue, tech stack, and any custom signals that matter to your team.
- Pull matching prospects: The agent searches Apollo, Clay, LinkedIn, and your other data sources for companies and contacts that fit.
- Clean and check the data: It removes contacts already in your CRM, verifies email addresses, and flags accounts that are already in active sequences.
- Deliver to your workflow: Clean, prioritized lists go straight to your CRM, sequencer, or shared workspace, ready for your reps to start reaching out.
- Refresh on a schedule: The agent re-runs your list builds automatically (weekly, bi-weekly, or daily) so your team always has fresh targets.
What outcomes to expect
The first thing you'll notice is faster lists with better accuracy. Your reps spend their time on outreach instead of research, and every contact they reach out to actually matches your targeting criteria.
Over time, you'll have a repeatable system that grows with your team. New reps start with quality lists from day one instead of figuring it out from scratch.
Implementation expectations
We connect ICP List Builder to your prospecting tools and CRM. Here's what the setup looks like:
- We connect your CRM and data sources (Apollo, Clay, LinkedIn, and anything else you use).
- Together, we define your ICP filters, exclusion rules, duplicate-checking logic, and where lists get delivered.
- We launch with monitoring in place so you can see how list quality is tracking and adjust your criteria based on real results.
FAQ
Can we use different ICP definitions for different segments?
Yes. You can set up separate profiles for different products, regions, or customer segments and run independent list builds for each one.
How does it avoid adding contacts already in our CRM?
Before delivering any list, the agent checks every prospect against your CRM. It removes existing records and skips accounts that are already in active sequences.
How often can we refresh our lists?
As often as you need. Most teams run weekly or bi-weekly refreshes, but you can run them daily or on-demand when you're launching a new campaign.
