You’re not buying software. You’re buying capacity.
We put AI to work on the email, calendar, books and phones you already pay for, so your best people get back to the hard jobs. Drafts wait. Nothing goes out until you say so.
Based on Hilton Head Island. Working with owners across the Lowcountry, from Charleston to Savannah.
You know technology could help. You don’t know what’s actually useful.
You want capacity.
Your best people aren’t short on skill. They’re short on hours.

Why now
Remember 2002? Every dentist, law office and hardware store suddenly needed computers, email and a network, and almost none of them could set it up alone. So every town had a computer guy.
AI is that moment again.
You need someone to put it to work on the systems you already pay for, then train your people to run it, or run it for you. That’s sideKick.
Circled jobs open into the full story.Pattern examples, not client case studies. Every one waits for a person to send.
Cash · Anyone who invoices: trades, professional services, light manufacturing
Invoices, chased.
Frees you, or the controller stuck in collections
Open invoices and quiet customers pull your best people off the week’s real work. Capacity builds a ranked chase list with context: who’s late, what’s already been promised, who got an exception. It drafts reminders in your voice. Anyone you already cut slack stays off the list. The books stay yours. Your controller gets back to the hard calls, not the chase list.
Customers · Field crews · Service trades · Anyone with after-hours customers
Messages, drafted in your voice.
Frees you and whoever owns the phone or desk
After the last crew leaves, the phone keeps going. Calls, texts, forms and email pile up overnight. By morning they are sorted into your daily update: who reached out, what they asked, a reply drafted in your voice, and real openings on the calendar. Your lead tech stays on the job. Your desk person stays out of the voicemail hole.
People · Every business that’s hiring
Applicants, screened and matched.
Frees you, or whoever does hiring on top of their real job
Applications sit for days because the person who screens them is running two jobs. Good people take another offer. Capacity reads each application against the roles you actually have open, matches each person to the role that fits them best, and sorts them into yes, maybe and not now with the reason shown. It drafts the reply and the interview invite. You decide who you meet.

CashBills, checked against the quote.
Cash · Any business with vendors and more than one billing system
Frees you and whoever owns payables and the books
Paying vendors wasn’t on the calendar. It ate evenings, often yours, sometimes your bookkeeper’s, across two billing systems and a pile of invoices. Capacity turns that into a Monday routine: every bill checked against the quote or order it came from, anything that doesn’t match flagged, then vendor-by-vendor recommendations with the reasoning shown. A human checks the logic. The person who used to chase PDFs at 9pm gets a focused Monday block instead.
CustomersReviews and requests, handled.
Customers · Restaurants · Shops · Hospitality
Frees the GM or guest lead to be on the floor, not in tabs
Reviews, guest notes, and competitor noise stay scattered while the floor is already moving. The person who owns guest burns the open digging through stars and threads. Capacity joins them into one short brief before they sit: themes worth a human look, a sharp guest comment that needs a reply, and signal from down the street. They walk the floor with judgment, not a browser full of tabs.
FocusEvery task, in one list.
Focus · Owners running more than one company, location or crew
Frees you and the #2 who keeps the whole week in their head
The to-dos live everywhere: email, texts, the calendar, sticky notes, one person’s head. Capacity pulls them into one list across the tools you already pay for, with what needs a human today at the top and drafts ready for the asks that matter. It arrives as your daily update, not another dashboard to remember.
FocusTomorrow, planned.
Focus · Field crews · Service trades · Multi-location teams
Frees you, and whoever rebuilds the schedule at night
Someone stays late every night rebuilding tomorrow: who goes where, which truck, which job moves when a person is out. Capacity drafts tomorrow’s plan from the calendar, the jobs, and the routing and scheduling tools you already have. It flags what conflicts and has it ready before the day ends. A person looks it over and confirms. When someone calls out, the job that moves is already suggested.
The quiz
What could an agent take off your week?
Nine questions, about two minutes. You get three specific jobs, right here on the screen. Nothing is sent anywhere unless you ask.
How we start
One piece first. It stays if it’s useful.
No deck, no new software, no long contract. Twenty minutes to find where the week leaks, then one piece installed beside your team.
We work with owner-led businesses to find the core challenges eating the week, see how your team's capacity lines up against them, and identify where AI and agentic tools can give the hours back. Then we install that capacity beside your people, on the tools you already pay for: email, calendar, books and phones. Nothing goes out until your people send it.
What is an AI agent, and do I need one?
An agent is software that does a job step by step: reads the overnight messages, sorts them, drafts the replies. It is the tool. What you are buying is the capacity it creates, on the tools you already pay for, with your people deciding what goes out. The tools will keep changing. The hours you get back are the point.
Can I trust AI with my customers?
Everything waits as a draft. Nothing goes to a customer, vendor or candidate until someone on your team hits send. You decide what stays human.
Do I need to buy new software?
No. Nothing gets ripped out and there is no new login to learn. It runs on what you already write checks for.
Is my data safe?
Security comes first. Your systems, your data, your call. The work runs on the tools you already pay for, nothing gets ripped out, and you keep everything either way. Nothing goes out without a person sending it. Keith covers the specifics, like access and agreements, in the 20 minutes.
Will this replace my people?
No. It sits beside your team. Your people keep the judgment calls, the customers, the crews and the closes. Capacity takes the copy-paste and the chasing so they can.
What does it cost to start?
The first 20 minutes are complimentary, and you leave knowing one place it helps this week. If it fits, the next step is the Capacity Map, a paid one-week engagement. Keith scopes it and sends a clear number before any paid work.
How fast will I see something?
After the Capacity Map, we install one piece on your tools. You see a result in about ten days, and real operating change in about ninety. No lock-in.
What size business is this for?
Owner-led businesses where the week is short on hours, usually 5 to 200 people: field crews, contractors, restaurants and shops, professional services and light manufacturing.
Where do you work?
sideKick is based on Hilton Head Island and works with owners across the Lowcountry: Hilton Head, Bluffton, Beaufort, Jasper County, Charleston and Savannah. Most of the work runs on your own tools, so remote work is possible too.
