SANDBOX is a digital studio for operators. We design the site, ship the app, wire the CRM, run your Amazon store and hand the busywork to automations — so your business runs like a system instead of a second job.
We built the site for the Munich music & media agency behind artists pulling 50M+ monthly listeners and 500,000 tickets sold.
Most agencies hand you a pretty website and disappear. We build the whole chain — the thing customers see, the storefront they buy from, and the machinery behind it that follows up, books, and closes.
Custom sites and landing funnels that look like a company worth paying — built to load fast and convert.
Explore → 02Stores designed to sell: theme build, product pages, checkout tuning and the apps that actually pay for themselves.
Explore → 03Custom iOS and Android builds, or a working internal app in Glide or AppSheet in a fraction of the time.
Explore → 04Every repeated click costs you margin. We map the workflow and hand it to Make, n8n or Zapier — then prove the hours back.
Explore → 05Agents that answer leads at 2am, qualify them, summarise the call and write the follow-up — in your voice, on your rules.
Explore → 06HubSpot, GoHighLevel, Pipedrive or Zoho — configured around how you actually sell, so nothing leaks between interested and paid.
Explore → 07Brand Registry, listings, A+ content, Brand Store design, PPC and UGC — the full seller stack, run by people who sell on it.
Explore → 08Rankings that compound and a feed that doesn't go quiet. Content, technical fixes and reporting you can actually read.
Explore → 09We build the revenue machine itself: ICP, lead sourcing, outbound infrastructure, scoring, routing and attribution — wired end to end.
Explore →Two products of our own are in active development. They are where we prove the stack on ourselves before we put it anywhere near your business — same CRM, same automations, same AI layer we sell.
Food delivery app
Ordering, dispatch and rider tracking in one app — built on the same automation and notification stack we deploy for clients, under real traffic rather than a demo account.
Health CRM
A CRM built for clinics and care providers: patient pipelines, appointment and recall automation, and intake that doesn't rely on somebody remembering to call back.
You get a written scope, a number and a delivery date before a single line of code. No hourly drift, no surprise invoice at the end of the month.
The same team that designs the page wires the CRM behind it. Nothing falls through the gap between "the design guy" and "the tech guy" — because there isn't one.
Every automation ships with a before-and-after: hours removed per week, response time cut, leads recovered. If it doesn't move a number, we don't build it.
Your domain, your CRM sub-account, your repo, your API keys. We hand over documentation and a loom walkthrough so your team can run it without us.
You talk to the people building it. No account manager relaying messages to a team you never meet.
We manage projects and client relationships across multiple international markets, adapting to different time zones, business environments, communication styles and operational requirements. It has taught us to communicate clearly, work asynchronously, coordinate deliverables across time zones, and hold the same standard wherever the client sits.
Ten consecutive five-star reviews, every one from a paying client.
A bilingual studio site in Aarau where members browse class types, book sessions and manage memberships.
Reviews, team video and two named advisers with their own booking buttons — trust built in the order a cautious client needs it.
Emergency water damage work sold on expertise, with a free consultation form and a seven-step checklist for people mid-flood.
Chris set up our entire sales pipeline from scratch and it transformed how we operate. Five stages, smart automation, deal scoring, and mobile-optimized views. But more importantly he understands sales process, not just software. The pipeline isn't overcomplicated or feature-heavy. It's designed around how we actually sell. Hot deals are flagged instantly, automations move deals forward without manual intervention, and the team adopted it immediately because it makes their job easier. Delivered in 4 days, included training video for the whole team, and stayed responsive to feedback. Since launch, pipeline visibility went up, team accountability went up, and we're closing deals 3 days faster on average because nothing stalls anymore.
[SANDBOX] was excellent to work with. He created my GHL funnel and workflows professionally, responded quickly, and made revisions very fast whenever I needed changes. Communication was clear throughout the whole process, and everything was handled professionally. Really happy with the final result and would definitely recommend him to anyone needing help with GHL funnels, automations, and workflows.
Christopher delivered a sharp sales snapshot that positions GHL properly — outcome-focused, not feature-heavy. The design is clean, copy is tight, and it's built for our target market: startups with weak backend infrastructure. Promised 3 days, delivered in 2. Takes feedback quickly and implements same-day. No fluff, just solid execution. Already used this in sales conversations and it's working. That's what matters — it actually sells.
I'm extremely happy with the service I received! The seller was knowledgeable, easy to communicate with, and completed my GoHighLevel pipeline and forms setup exactly as requested. Everything was organized, functional, and delivered on time. They paid attention to the details and ensured the setup worked flawlessly before marking the order complete. The entire process was smooth and professional. I truly appreciate the quick turnaround and willingness to help.
Great job on my website. He was easy to work with, communicated well, and made the whole thing way less stressful than I thought it would be. The website came out clean, professional, and exactly what I needed. I'm super happy with it and definitely recommend him if you need someone to build your site.
[SANDBOX] really went to great lengths to keep up with my evolving instructions and I really appreciate that. The job was completed successfully and I will work with him again.
Fact is that [SANDBOX] finished the project ahead of time. So quickly I missed the window to review, but his knowledgeable response to what the true requirements of the job was reassuring he understood the job. Highly recommend!
Really happy with everything! He built my GHL funnel to a high standard, got it done quickly, and communication was great the whole way through. I will definitely work with him again.
Amazing find of knowledge and work ethic. Will continue to use for all our technical support needs.
Great work from [SANDBOX] — knows the product and worked within the timeline he set.
A 20-minute call. We'll map the system, tell you what we'd build first and what it costs. If we're not the right fit, we'll say so.
Nine service lines that stack. Take one, or let us build the whole chain — site, store, app, CRM and the automations that keep them talking to each other.
Your site is the only salesperson that works every hour of the year. We design it around one job — getting the right visitor to take the next step — then build it fast, accessible and easy for you to edit.
Custom design, no recycled template. Sub-two-second loads. Copy structured around objections, not features. We also build fast on Onepage where a single high-converting page beats a full site.
Start a website ↗Most Shopify stores lose money in the same three places: a product page that doesn't answer the obvious question, a checkout with friction in it, and a back end nobody connected to anything. We fix all three.
New builds, migrations and rescue jobs on stores that were set up in a hurry.
Build my store ↗From a napkin sketch to a listing on both stores. We scope the smallest version that proves the idea, ship it, then grow it on what real users actually do — not what the roadmap guessed.
Custom builds in React Native or Flutter when the product needs it — or a working internal app in Glide or AppSheet in days, for a fraction of the cost, when it doesn't.
Scope an app ↗Every business has a handful of tasks someone does twenty times a week: moving data between tools, chasing a signature, formatting the same report. We find them, cost them out in hours, and replace them.
Built in Make, n8n or Zapier — documented, monitored, and with a fallback when an API has a bad day.
Audit my workflows ↗AI that does a defined job well, not a chatbot bolted to your homepage. Answering enquiries in under a minute, qualifying them against your criteria, summarising calls, drafting the follow-up in your tone of voice.
Grounded in your own documents and rules, with guardrails and a clear escalation path to a person.
Explore AI systems ↗Most CRMs fail because nobody configured them for how the business actually sells. We build the pipeline around your real process, automate the chasing, and make the dashboard tell you the truth.
Certified across the four platforms most businesses land on — and happy to take on the account someone half-built and abandoned.
Amazon punishes guesswork. Rankings come from a listing built on real search terms, creative that answers objections before the scroll, and ad spend pointed at the terms that convert — in that order.
Whether you're registering a brand for the first time or rescuing a stalled catalogue, we run the account end to end.
Search brings people who already want what you sell; social keeps you in mind for the ones who don't want it yet. We run both off one content plan so the work compounds instead of competing.
Reporting in plain English: what moved, what it cost, what we're doing next month.
Grow my reach ↗Most businesses have marketing in one place, sales in another, and no system joining them. GTM engineering is the discipline of building that join — treating go-to-market as infrastructure you can version, measure and fix, instead of a set of habits that live in someone's head.
We define who you sell to, build the pipes that find and reach them, score and route what comes back, and instrument the whole thing so you can see which part is actually producing revenue.
Send us the thing that's costing you the most time or the most leads. We'll tell you which of the nine fixes it — even if the answer is "you don't need us yet".
Book a call ↗Seventeen recent builds across four continents — property, legal, insurance, restoration, logistics, staffing, fitness and e-learning. Where the site is public, the card links straight to it.

Three service worlds — artist promotion, media performance and employer branding — plus an artist roster, project gallery, a full team wall and a scoped enquiry form. Their numbers do the selling: 50M+ monthly listeners, 500,000 tickets sold.
The German transport operator rebuilt from the ground up: a proof bar (2+ years, 98% on-time, 100+ clients, 4.9★), six service tiles from direct drives to valuables transport, three signature offers, an FAQ, and a quote form sitting on the map.
Fast, hassle-free property solutions for sellers in difficult situations — a hero lead form, three client paths, before-and-after proof, a blog engine and a referral capture block, all on one route to a conversation.
Private lending, cash offers and wholesale deals across service pages, testimonials and a blog, with enquiry forms routing sellers and investors down separate paths.
A German advisory firm for private and business clients. Five-star review bar and team video up top, three reasons to trust them, client voices, and two named advisers each with their own "Termin buchen" booking button.
A coming-soon page for a residential build that still had to sell units. Email capture in the hero, three buying arguments, a four-stage construction tracker, architecture galleries and a closing stat band.

A standalone valuation tool for an estate agency: owners answer a short series of questions about their property and land in the agency's pipeline as a qualified lead.
"Don't feel helpless — we fight for justice." Six practice areas from business to personal injury, a credibility bar of case and client counts, a recent-cases gallery and an attorney directory.
A course business built on a free resource library: tutorials and templates pull people in, then three priced tiers — beginner belt work through to advanced leather goods — convert them.
A single-page offer for a customer-acquisition consultancy in Zurich Oberland: free audit at the top, three packages below, one action per screen.
Seven coverage types — Medicare, hospital indemnity, long-term care, whole life, retirement income, travel and estate planning — each given its own card so visitors self-select before they ever call.
One question in the hero — what is your home worth? — answered in three steps that take under thirty seconds. Email first, valuation report delivered to the inbox, agent gets a warm seller lead.
Direct routes, high-value cargo and same-day delivery for an operator where discretion is the selling point — built around a fast path to a transport quote.
A woman-owned workforce solutions firm serving government and corporate clients across DC, Virginia, Maryland and Tampa — with separate routes for employers requesting staff and candidates hitting the job board.
Audit, bookkeeping and CFO support under Swiss GAAP FER and IFRS — a site carrying the precision and restraint a financial audit firm is judged on.
No projects in this category yet — yours could be the first.
Every case study above started as a call about something that wasn't working. Tell us yours and we'll show you what we'd change first.
Start a project ↗SANDBOX started in 2026 for a simple reason: too many good businesses were being sold beautiful websites that did nothing, and software nobody had bothered to connect.
I'm a GoHighLevel specialist, AI automation expert and digital systems builder. I help businesses turn their ideas, processes and customer journeys into systems that actually work.
My work spans GoHighLevel, CRM automation, sales funnels, workflows, websites, AI agents, voice AI, lead management, SaaS and white-label systems, and third-party integrations — building, optimising and connecting the systems a business needs to generate leads, manage customers, automate communication and streamline operations. I also build on Onepage.io for modern, conversion-focused websites and landing pages that plug straight into that marketing and automation stack.
One thing I'm particularly proud of is managing projects and business relationships across multiple international markets — Nigeria, the United States, the United Kingdom, Switzerland, Germany, Spain and Canada — adapting to different time zones, business environments, communication styles and operational requirements. That has taught me to communicate clearly, work asynchronously, coordinate deliverables across time zones, and hold the same standard wherever the client sits.
My approach goes beyond completing a technical task. I start with the business objective behind the project, find the gaps and the opportunities, then build the solution around the outcome the client actually needs — CRM builds and migrations, AI receptionists, appointment systems, automated follow-ups, funnels, A2P compliance, e-commerce workflows, API integrations and custom automation. Practical, scalable, and easy for the business to operate.
Don't just automate a process — build a system that helps the business grow.
GoHighLevel, AI systems and go-to-market engineering — working across Nigeria, the UK, Europe and North America.
Three packages, ten published starting prices, and a custom quote for anything that doesn't fit either. Every engagement starts with a consultation before a number is agreed.
For a business that needs to look credible and start capturing leads properly.
For a business with leads coming in that keeps losing them to slow follow-up.
For an operation ready to replace headcount-per-task with software.

Starting prices in USD — final scope and cost confirmed after discovery.
Tell us the outcome you want and the budget you have. We'll come back with a scope that fits both, or tell you honestly that it doesn't.
