Braintrailz · Marc J. Greenberg

    Two ways of thinking.One trail.

    Some people arrive with a spark they can't stop thinking about. Others arrive with a stack that has to work by Monday. I build for both.

    The creative side

    I have an idea

    Turn ideation into something special.

    The analytical side

    I need it built

    Fractional CTO. AI that ships.

    Both sides lead to the same campfire: one conversation, one punch list.

    Walk the Trail

    From spark to something special

    Braintrailz turns ideation into delivered systems. I sit at the fire with you while it is still a wild idea, then stay to build the thing that carries it.

    Spark

    You have an idea you can't put down.

    Bring it rough. That is the best time to talk.

    Shape

    We map it.

    Who it is for, what it must do, what it can skip.

    Build

    Then I build it with you.

    The same engineering I bring to a CTO seat.

    Things that started as a spark

    IBM Boca Raton. Twenty years at Information Builders and iWay. BuildingLink across 5,000 buildings. Logistics AI. Office of the CTO at Partech. Then Braintrailz. The current proof is BLT.

    Beyond Limited Thinking

    Beyond Limited Thinking

    AI-native POS for restaurants and hospitality. Payments freedom, not another terminal lease. This is what I am shipping now. Proof I still build, not just advise.

    Work the Trail

    What you can buy

    One person. Three ways to hire me. Most people start with the half-day because it turns a vague AI worry into a list of work.

    Start here

    Half-day strategy session

    4 hours with your team. A week of prep by email. You leave with the work.

    • Custom session using the Functional Technology Framework
    • Immediate punch list and bloodspots
    • Technology projects for the next 1 to 6 months
    • Credit on the first advisor invoice if we continue
    90-day sprint

    CTO Engaged

    I sit in the chair. Strategy, vendors, stand-ups, the map.

    • Functional Technology Systems Map in the first 30 days
    • Weekly sprint planning and daily stand-ups
    • Hire, train, evaluate, and fire vendors and contractors
    • 3-month minimum
    After we have a map

    CTO Advisor

    I stay in the loop without owning the calendar. Lowest financial risk once the path is clear.

    • Opens after a half-day or a 90-day Engaged sprint
    • Twice-monthly sprint planning, quarterly planning
    • Unlimited email
    • 6-month commitment

    How an engagement actually works

    This is not a five-step agency waterfall. It is a sequence that earns the next conversation. I do not run your sales. I am the technical right arm once the problem is real.

    01

    Half-day

    A week of prep by email, then four hours with your team. You leave with a punch list, and the roadmap for the next 1 to 6 months of technology work.

    02

    90-day Engaged sprint

    If the punch list is real, I sit in the chair. Map in 30 days. Weekly planning. Daily stand-ups. Vendors and contractors get managed. Short-term, high-octane.

    03

    Advisor

    Once the path is clear, I stay as a strategic advisor. Twice-monthly planning, unlimited email, lowest ongoing spend. You do not start here.

    Who this is for

    Hire me if

    • Operators and founders in hospitality, restaurants, proptech, or payments who need a technical right arm
    • Accounting and advisory firms that need a senior leader to build and operationalize an AI strategy
    • Teams that know they are 6 to 10 months behind on AI and want a map, not a vendor tour
    • Leaders who want a CTO-level peer in the room, then someone who will stay and execute
    • A real software company that needs an engineering leader who still builds: management, architecture, ideation, shipping. I am a builder

    Skip me if

    • A ticket queue with a title. Staff-aug, body shop, or a manager seat that never touches the product. I am a builder
    • Anyone who wants me to run sales, marketing, or the pipeline
    • A research graduate with no shipping experience. That is not my profile
    • A free architecture review dressed up as a coffee chat
    • A spray-and-pray recruiter blast with no real problem attached. If the seat is real and the work is mine, we can talk

    Base Camp: let's talk

    Bring the spark or bring the stack. I reply within 24 hours.
