De-Risked Entry into
Europe's Home-Growing Market.
Germany legalized cannabis home-growing in 2024 — 4.5M regular consumers, 3 plants per person legal, $10B+ TAM. Netherlands, Czech Republic, and Malta are following. No dominant all-in-one ecosystem player exists in Europe yet.
growSMART is a patented, modular home-growing ecosystem that generated >€200K in revenue across two product generations — fully bootstrapped. The full IP, brand, molds, inventory, and 7,000+ qualified leads are ready. A restructuring (triggered by a supplier termination, not a product or market problem) means the assets are available now.
Minimum seed investment of €650K via convertible note — cap & discount finalised on the call. 18-month runway to cashflow-positive. Full model in the Pitch Deck.

Lifetime Value
"We built this company from the ground up — product, infrastructure, sales — and proved it works. Now we need a partner to remove the one bottleneck that remains: capital."
A Complete Ecosystem,
Ready to Scale.
growSMART is a patented, modular indoor-growing ecosystem. 30 products developed: from the growMACHINE climate computer (touchscreen, WiFi, CAN-BUS) to fully automated growing systems. Every device communicates via CAN-BUS with proprietary interfaces — creating hardware lock-in and recurring revenue from add-ons.
Average hardware cost: €650. Average cart value: €1,100. Average CLV: €2,100 (1.9× repeat from consumables + expansions). This is a razor-and-blades model with proven economics.
US Patented · CAN-BUS Architecture · Hardware Lock-In
growMACHINE
The brain of the entire ecosystem. Automates ventilation, filtration, lighting, and climate — via touchscreen, WiFi, and CAN-BUS. Protected by US Patent US11627707B1.
Sensors measure temperature, humidity, and CO₂. The microcontroller adjusts everything in real-time. All 30 products build on this central unit — a closed ecosystem with expansion revenue.
Three Methods — One Brain
Aeroponic growing — maximum yield, 50%+ more than soil. Complete set incl. growMACHINE.
Rockwool-based ebb-and-flow. Up to 30% more yield than soil, clean and controlled.

Digital step-by-step cultivation guide.
AI-Driven. Sub-5-FTE.
The Real Moat.
This isn’t just a hardware company. The entire sales, marketing, support, and fulfillment infrastructure was built from scratch — AI-powered, fully automated, and designed to scale to €10M+ revenue with fewer than 5 operators.
Five traffic channels — Ads, SEO, AI Search (GEO/AEO), Social Media, and Affiliates — all funnel into one conversion-optimized landing page. The customer purchases in the shop, and n8n triggers the chain: AI routes via GPT, Claude, or Gemini, Mautic sends behavioral emails, CRM tracks the lead, WhatsApp answers 24/7. The retention loop closes the circle: recurring revenue comes back through email sequences, the WhatsApp AI bot, and on-site AI chat — for free, because you own the list and the channels.
Open Source. Minimal License Fees.
Self-hosted, open-source core keeps recurring software costs to a minimum — margin stays with the company instead of leaking into per-seat SaaS subscriptions as we scale.
This is What the Infrastructure Looks Like.
Real screenshots from the production system. CRM dashboards, AI chatbot, architecture diagram, affiliate ecosystem — no mockups, no demo data.
360° Customer Intelligence & Pipeline Management
Mautic behavioral nurturing, automated revenue recovery for lost carts, active deal flow from first contact to closed deal, and deep user profiling across every digital touchpoint — all feeding one unified customer view.
Context-Aware AI Sales Agent via WhatsApp
RAG architecture combining real-time Supabase access with LLM intelligence. The agent pulls live order status, inventory, and pricing data — then answers via WhatsApp, Telegram, or web chat. 24/7 support without human intervention.
Scalable & AI-Driven Commerce Infrastructure
WordPress + Supabase as Central Data Hub, n8n event-driven workflows, AI Agent Layer for 24/7 support & sales, D2C & B2B frontend with dynamic pricing — zero enterprise license fees, maximum EBITDA margins.
Multi-Level Partner Ecosystem — Zero CAC
Automated affiliate onboarding, multi-level partner logic with sub-partner recruitment, real-time analytics dashboard, and fully automated commission payouts. Partners scale the network — zero customer acquisition cost.

AI Becomes the Company Operating System.
With capital + 2–3 operators + AI, the existing infrastructure scales from six- into seven- and eight-figure revenue — without a classical 15-person ops team. The foundation is in place; funding the full build-out is what unlocks the outsized return.
Claude Code in the Dev Loop
Anthropic’s Claude Code builds features, writes tests, generates marketing copy and maintains the knowledge base — engineering output of a 3–4 person team with a single developer. This is the leverage that turns a solo founder post-restart into a 5-FTE operation scaling past €10M revenue.
AI Sales Agent on WhatsApp
RAG-powered, live catalog + inventory + customer history. Qualifies, upsells, books 24/7 in the customer’s language.
Scales Without Headcount
Designed for €10M+ revenue with <5 operators. AI + automation absorb what would need a 15-person ops team.
Integrated, Not Glued
Shop, CRM, email, WhatsApp, AI — one data layer via n8n.
Data Sovereignty
Hetzner EU. GDPR-native. No vendor lock-in.
Multi-Provider AI
Claude (reasoning & code) · GPT (sales & content) · Gemini (multimodal & pricing) — each task routed to the strongest model. No single-provider risk, no lock-in.

The Infrastructure Was Built.
Marketing Was Not.
All resources went into product development and production — 30 products, CAN-BUS architecture, US patent, full tech stack. Marketing and growth were deprioritized because the founder was the only person doing everything. With capital and AI automation, this changes completely: the infrastructure is ready to scale to 10,000+ orders per month. The only missing piece is fuel — funding for inventory, marketing, and key hires.

10 Years of
Building.
The complete story — from engineering degree to restructuring. Each chapter: a problem, a decision, a result.
Mechanical engineering degree — with a product in parallel.
Mechanical Engineering at TH Wildau, Bachelor's degree in 2020. From ~2019, product development work starts during the studies — the gap in the home-growing market gets identified, the first FlowaOne prototypes are built.
FoundationEngineering background + first hardware iteration — the groundwork for everything that follows.
A German hardware startup founded in Berlin. FlowaOne in production.
Hardware company founded in Berlin with a co-founder. FlowaOne — All-in-One Grow Light, Made in Germany — produced entirely in-house in a Berlin basement. Luminus COBs, ebm-Papst fans, activated-carbon filters from recycled material. Initial price: €1,399.
BootstrappedFinanced by friends & family in the low five figures — no VC, no external debt. Each unit hand-built and tested.
US Patent granted. FlowaOne sold out.
US Patent US11627707B1 granted on the FlowaOne climate-computer architecture — the same IP that protects today's growMACHINE. 125 units produced, ~100 sold, price reduced to €999 at the end — sold out. YouTube & Instagram channels built alongside the product, entirely in-house.
ValidatedProduct-market fit proven in a high-involvement €1,000+ segment — with ~€2K total ad budget over four years.
From single product to 30-product ecosystem.
Strategic pivot to growSMART. growMACHINE with touchscreen, WiFi, CAN-BUS architecture as direct FlowaOne successor. Components sourced from China, full container imported. Complete tech stack built in parallel. Co-founder leaves at year-end — the original operating entity is wound down and activities continue through the holding structure with the founder at the helm.
Infrastructure BuiltWordPress + WooCommerce, n8n, Mautic, WhatsApp AI chatbot, CRM — all self-hosted, minimal license fees.
€800 ad spend → €10,000+ revenue in 2 weeks.
MVP test: €800 budget, >€10,000 revenue, >12.5× ROAS. Market validation complete — production triggered.
Key InsightThe infrastructure was the multiplier. Same product segment, radically different outcome.
7,000+ leads. Six figures in under one year.
Full pre-sale launch: 30 products. ~€30K marketing budget. 7,000+ leads. 30-40% email open rate. Six-figure revenue in under one year — 8× faster than Phase 1.
ButAll resources went into production. Marketing and growth infrastructure remained underutilized — the founder was the only person doing everything.
An external electronics supplier terminated during production.
Production started in Berlin. ~60 customers supplied, ~90 orders active. Then: the external electronics supplier terminated. Single point of failure — not a market, product, or infrastructure problem.
What SurvivedAll assets survived: Tech stack, brand, domain, 7,000+ leads, inventory (~€40K), IP, US Patent, content, affiliate + B2B network.
The assets are ready. The market is waiting. Capital unlocks execution.
Restructuring proceedings underway. All IP, brand, molds, inventory, and the complete tech stack remain available. Electronics will be brought in-house. With capital for inventory + marketing, and AI automation absorbing what would otherwise be operational headcount, the infrastructure can finally run at full capacity — targeting the European legalization wave at exactly the right moment.
