The Infiltrate Strategy

The second a new customer says yes, you don't sit back and wait for the next pour. You get behind enemy lines and meet every single person in their building.

What infiltrate actually means

In sales terms, infiltrate means get inside the account — past the one person you closed — and build relationships with everybody else who touches the decision.

"Infiltrating the enemy means I get behind enemy lines and now I'm in there. I get to study from the inside, not from the outside. I get to be in."

When you're on the outside, you're stuck doing the front-door dance: "Hey, is Mo around? I just want to chat with Mo." When you're on the inside, you're walking the halls, introducing yourself to the accountant, the foreman, the owner's daughter-who-handles-billing, the estimator's apprentice who's about to become the next estimator. You're mapping the cast of characters.

Every one of those people is going to have a vote — direct or indirect — on whether your company gets the next job. Most sellers close one person and think they've won the account. They haven't. They've won one vote. There's a whole election going on behind that door and they just don't know it.

When to infiltrate — right after the first yes

A lot of sellers get the first job and then take their eye off the ball.

"What a lot of sales guys do is they get that first job, and then they go working on other stuff, and they take their eye off the ball, and then they come back two weeks later and go, 'how'd the pour go?' It was good, you guys were a little bit late, but it wasn't bad. 'Oh okay, would you guys consider working with us again?' 'Yeah, we might use you from time to time.' What? We had an opportunity and we blew it."

The first job is the window. The customer just said yes. Everybody in the building is curious about the new vendor. Doors are open that would be closed again in 30 days. That's when you walk in and meet everybody.

After six months of doing fine work quietly, the curiosity dies and you're just another vendor. Infiltrate during the honeymoon.

The script — walking in and meeting the cast

The line I use:

"Hey, how do you guys handle your billing? Who is that? Let me make sure I know your billing person so that everything runs smoothly. Who else should I meet on your team? I just want to make sure that we're all bros and we can figure this out."

Notice what that does. You're not asking for permission to take over the account. You're framing the asks as logistics — "who do I call if there's a billing question?" — which is reasonable, useful to them, and opens the door for you to meet three more people.

Once you're in the meeting:

"I'm Carlos from Impact. Do you got a second? What's your role here? What do you do? Wow — is that what you were thinking when you'd be when you were a kid? How'd you end up here?"

You're not selling. You're interviewing. You're letting each person tell you who they are, what they do, and where they sit in the decision chain. Everybody likes talking about themselves. Nobody gets asked. You're giving them that rare thing — a stroke — just by being curious.

Meet anybody who walks into the room

A small but powerful habit:

"If somebody walks in and they're waiting for Paula to do something, say, 'hey, I'm Steve, I'm one of the suppliers.' Just introduce yourself to anybody that shows up. Somebody stops in the estimator's office. Don't just sit there. Go, 'hey, I'm Steve. How's it going?' Oh, you're the accountant. Hey, nice to meet you."

You never know who walks in. It could be the owner's brother. It could be the PM on the next big job. It could be the lady who signs the checks. Don't sit there pretending not to be there. Introduce yourself. Every time. You're showing up unannounced anyway — you're not hijacking their time, you're just saying hello.

Especially useful: "You don't play golf, do you?" Best case — you just met a new golf buddy. Worst case — they laugh. You lose nothing.

The meta-version — how I use it on my own business

I use the infiltrate strategy on my own deals. Watch how I sold my own consulting work into Mike's company:

"I met with Bob, he introduced me to the executive team. I suggested with Mike that I meet his team, and I got to meet all of you. Then Mike came around and said, 'hey, what do you think of that Steve guy?' And at that point, I had Bill, Bob, Ben, Mike, Carlos, Melissa, Janice, and Lydia all saying 'we like Steve.' I mean, I'm going to get that contract. I set it up making it look like they don't even know what's happening."

That's the play. Don't rely on the one person to champion you internally. Get eight people saying "we like Steve" before the decision gets made, and the decision is made for them. The champion doesn't have to fight for you — there's no fight, everybody already agreed.

Why this is defensive as well as offensive

Every account you have right now has a competitor sniffing at it. If your only relationship is with the one estimator who buys from you, the day that estimator quits or retires or takes a call from my competitor's rep — your whole account is at risk. Single-threaded accounts evaporate.

Infiltrated accounts don't evaporate. When one person leaves, you still have seven other relationships. The replacement shows up and three people on their team tell them "oh yeah, we work with so-and-so, they're great." That's the account surviving a transition. Non-infiltrated accounts don't survive transitions.

"Their other rep doesn't know everybody. Their other rep — the other rep doesn't. So once you get your one in, and you start digging in, then you're going to have to meet somebody else. And by the time you've met seven or eight people in there, it's very hard for somebody else to take that account from you."

The gifting move (when appropriate)

A specific move that pays off: gift people outside the decision-making role. The estimator's wife, for instance.

"Hey Ruben, take your wife out for me. She was so helpful when I called in, and I really appreciate your business. Go have dinner on me this week." ... And you don't think the wives can be like, 'Ruben, are we working with that new supplier now?' This is part of my infiltrate strategy. So even though they have a home office, you've got a home address."

A small gift card to a nice restaurant near his house, note in it. Now you've infiltrated the kitchen table, too. The wife is now in the loop. That's leverage you didn't have before, built from a $75 gesture.

(Use judgment. Don't gift anybody whose compliance rules prohibit it, and don't make it transactional. It's a thank-you, not a bribe.)

Build the cast-of-characters map

For each active customer, you should be able to name:

If any of those are blank for your top ten accounts, those are this week's infiltration targets. Go fill in the blanks. Introduce yourself. Learn their names. Earn a 5-minute conversation.

Homework — the infiltration audit

  1. Pick your top five accounts. For each, list every person you currently have a relationship with (name + role).
  2. For any account with fewer than four names on the list, that's an infiltration target. Pick one this week.
  3. Physically go to that account. Don't email. Show up, bring coffee for the gatekeeper, ask who else you should meet. Get two new names onto the list.
  4. In the next 30 days, aim for every one of your top ten accounts to have at least five named contacts across the six roles above.

Report back on which account got thicker and what happened on the next pour.
