CSK Growth Partners mark Operator-led · Systems-driven · Results that scale

We build the operating systems that scale high-performing businesses.

For founder-led companies — often across multiple operating entities — that have outgrown manual back-office work. Operations and AI strategy, diagnostic-first, every recommendation underwritten with a quantified payback.

Built by an operator who installed this playbook into 4,000+ field service contractors. Carolinas + Southeast. HVAC, plumbing, electrical, restoration, commercial cleaning.

The Problem

The product is fine. The system around it is leaking.

Most $5–50M field service operators have leads, trucks, and tenure. What they don't have is the operating system that turns lead volume into booked revenue — without the owner in every conversation.

1

Calls outrun the office

Inbound comes in faster than the team can answer. Missed calls are missed jobs — and the lead calls your competitor at 9:01.

2

The CRM is installed but underused

Half the team is on it. The other half lives in their truck and their head. The data you report on isn't the data the work runs on.

3

Conversion is a guess

Lead-to-appointment, close rate on open quotes, technician utilization — measured loosely, if at all. So is the coaching that fixes them.

4

Reports lag the calls by a week

By the time you see the gap, the month is gone. The fix requires a weekly cadence, not a monthly dashboard.

None of this is a software problem. It is a system problem. A system your team can run without a consultant in the room.

What We Install

The AI Revenue Engine. Three systems. One operator on it.

We don't sell tools. We install the system around the tools you already have — ServiceTitan, Housecall Pro, Jobber, HubSpot — and add the AI layer that closes the loop.

01

Lead Capture & Response

AI-driven intake on every call, web form, and missed call. Instant text-back. Same-hour follow-up. The lead that called your competitor at 9pm calls you back at 9:01.

02

Pipeline & Booking

CRM cleaned up. Dispatch integrated. Lead-to-booked-job conversion measured weekly. Every job has a source, a rep, and a number.

03

Operating Cadence

Weekly KPI review. Board-ready monthly report. Quarterly deep dive. The accountability layer most field-service businesses are missing.

How We Engage

Three productized engagements. No custom scope.

Defined scope. Defined deliverables. Defined accountability. Pick the entry point that fits where you are.

How We Work

Diagnose. Build. Run. Optimize.

Most "AI transformation" engagements skip straight to the tool. We don't. The cost of the wrong pilot isn't the software bill — it's the calendar quarter you lose proving it didn't work.

01 / DIAGNOSE

Map the work

Trace how leads, calls, jobs, and dollars actually move through the business — and where they stop being automatic.

02 / BUILD

Install the system

Configure the CRM. Write the scripts. Automate the follow-up. Stand up the dashboard. Train the team — twice.

03 / RUN

Operate it live

Weekly KPI cadence with the team. Live call review. Adjust in real time. The system has to survive contact with the truck.

04 / OPTIMIZE

Lock in the gains

Final performance report. 30-60-90 roadmap. Operations playbook. Recorded walkthrough. Then we leave the team running it.

Why CSK

Three principles. No exceptions.

These aren't values on a website. They're the filter every engagement runs through.

Operator-led

Built by an operator who has installed this playbook at scale.

Not a consultant who has read about it. The 4,000-contractor channel at Sunlight is the same system, applied to a different vertical.

Systems-driven

We install systems that compound. Not strategy decks that sit on a shelf.

Every recommendation has a configuration, a script, a dashboard, and an owner. If it can't be operated weekly, it doesn't ship.

Results-focused

Measurable revenue lift in 90 days. Tracked weekly. Reported board-ready.

Headline KPI selected at Day 14. Baseline measured before anything changes. Before/after on every metric at engagement close.

Who you'll be working with

An operator who has done the job — at scale.

Chris Kastler, Founder of CSK Growth Partners
Chris Kastler Founder, CSK Growth Partners · Charlotte, NC

CSK Growth Partners is led by Chris Kastler. Before founding the firm, Chris spent eight years at Sunlight Financial — a PE-backed solar fintech that processed $12B+ in funded loan volume — building and leading the SMB channel that integrated Sunlight's point-of-sale financing platform into 4,000+ independent field service contractors.

As Managing Director, he scaled channel credit approval volume from $24M to $1.2B annually: recruiting and onboarding contractor partners, training their sales teams to use financing as a closing tool, and building the underwriting and capital infrastructure that made the platform reliable at the kitchen table — cycle time cut from two weeks to same-day. He took the business through its 2021 IPO and was later promoted to lead a 40+ person joint operations organization.

Earlier roles at Bank of America (VP, institutional banking) and Capital One (FP&A) built the financial rigor PE sponsors expect. Inside engagements, Chris works with the 100-Day Playbook, MEDDPICC, and the Pyramid Principle — named frameworks, used on purpose.

Outside the work, Chris is a commercial real estate investor and a mentor at RevTech Labs. Clemson University, Magna Cum Laude.

How we communicate & qualify

Named frameworks. Used on purpose.

Operator-first doesn't mean off-the-cuff. The frameworks below are the ones we run inside engagements — and the ones we expect ownership groups to push back on.

The 100-Day Playbook

How we onboard new leaders and stand up new functions. The first 100 days set the trajectory of the next 1,000. Sequenced, accountable, board-reportable.

MEDDPICC

How we qualify pipeline and rebuild your sales motion. Metrics, Economic Buyer, Decision Criteria, Decision Process, Paper Process, Identified Pain, Champion, Competition.

The Pyramid Principle

Answer first, then the support. Every deliverable starts with the recommendation. The 60 pages behind it are for defenders, not deciders.

Let's talk

Bring one revenue bottleneck you can't seem to shake.

We'll spend 30 minutes on your problem, not our credentials. If the fit is right, you'll leave with a hypothesis worth testing. If it isn't, you'll leave with an honest answer.
