Build Your CleanTech MVP in 6 Weeks
Carbon tracking, energy monitoring, IoT sensor integrations (IoT means your physical devices talk to software), and ESG dashboards — shipped in 6 weeks with a fixed price. Our team understands sustainability rules so you do not have to learn them yourself.
Think of an MVP like the first pancake you make to test a new recipe. It is not perfect, but it is real and you learn from it fast. Whether you are building a tool to count carbon emissions, watch energy use in real time, or file an automated CSRD report (a new EU law that makes large companies report their environmental impact), we structure your product around the data rules regulators expect from day one.

Why CleanTech MVPs Are Different from Standard SaaS Builds
CleanTech products live or die on data accuracy. Think of a carbon counting tool like a bank statement. One wrong number and your enterprise customer faces real legal risk. The EU Corporate Sustainability Reporting Directive (CSRD) — a law that tells large companies exactly how to report their environmental impact — has applied to listed companies since 2024 and reaches mid-size firms through 2026. This means your minimum viable product cannot treat the data model as an afterthought. The calculation method, boundaries, and record trail must be correct from the very first line of code.
Unlike a typical SaaS product build, CleanTech tools face a unique cold-start problem. The value only shows up once real data — emissions figures, energy readings, supplier numbers — actually flows in. That makes your IoT connections (the pipes that bring device data into your software), your links to utility providers, and your CSV upload tool just as important as the dashboard itself. Enterprise buyers will not trust a demo with fake data. They need to see their own electricity figures appearing correctly before they will sign a contract.
Greta combines product engineering with deep knowledge of the GHG Protocol (the global carbon measurement standard), TCFD disclosure rules, and CSRD requirements. We scope every build around the real reporting obligations your customers face in 2026 and beyond. You ship a product that wins procurement approval — not just a pretty data dashboard.

What Your CleanTech MVP Will Include
Every module is built to real enterprise sustainability standards — not just a prototype that looks good in a presentation. Here is what a typical 6-week Greta CleanTech MVP delivers.
Scope 1, 2 & 3 Carbon Tracking
A carbon calculation engine that reads energy bills, fuel receipts, travel records, and supplier data to add up your customers' full carbon footprint. Scope 1 = what you burn directly. Scope 2 = electricity you buy. Scope 3 = everything in your supply chain. We support both main Scope 2 calculation methods out of the box.
Real-Time Energy Monitoring Dashboard
Live energy charts broken down by building, machine, or department. Charts use 15-minute readings from smart meters or building systems, with adjustable baseline comparisons and automatic alerts when something looks wrong.
IoT Sensor & Smart Meter Integration
Connections to IoT platforms, UK smart meters, and building management systems. We handle login, data limits, and cleanup so your users see clean numbers — not raw device signals they cannot understand.
ESG Data Collection & Stakeholder Dashboards
Structured data collection for environmental, social, and governance metrics. Role-based views for sustainability managers, CFOs, and board members. ESG covers three areas: how you treat the environment (E), your staff and community (S), and how you run the company (G).
Automated Regulatory Report Exports
One-click generation of CSRD, TCFD, and GRI-aligned reports in PDF and Excel. Templates stay current with the latest regulatory rules so your customers' disclosures stay compliant as standards change.
Immutable Sustainability Audit Trail
Every data point is stamped with its source, the time it arrived, and which calculation version processed it. This creates a clear chain of evidence for independent auditors. They can trace any figure back to the original raw input.

Our 6-Week CleanTech MVP Process
We work in short 2-week chunks called sprints — like chapters in a book. You see real progress at the end of every chapter. Here is exactly how your 6 weeks unfold when you build your startup MVP with us.
- 01
Sustainability Discovery & Data Mapping
In week one we run 2 workshops. The first aligns everyone on who will use the product and what they need. The second maps where your emissions data lives — utility bills, sensors, supplier spreadsheets — and which regulations apply to you (CSRD, TCFD, GHG Protocol). You finish week one with a clear product brief and a data dictionary (a plain-English list of all the data fields your product will handle).
- 02
Carbon & Energy Architecture Design
Our engineers plan the full data pipeline — how data enters your product, how the carbon calculation engine works, and how the IoT connection layer fits together. We choose between AWS or GCP cloud hosting and write up the full plan before a single line of product code is written. This stops expensive rebuilds later.
- 03
Sprint 1 — Core Dashboard & Data Ingestion
Weeks 2 and 3 build the most important part first: the carbon or energy monitoring dashboard with at least 1 live data source connected. You attend a demo at the end of week 3 and watch real data flow into the product for the first time.
- 04
Sprint 2 — Reporting, Audit Trail & Compliance
Weeks 4 and 5 add the regulatory report exports, the immutable record trail, and any extra data sources (supply-chain imports, more IoT feeds). We also add user roles so you can safely invite a pilot enterprise customer to review their own data without seeing anyone else's.
- 05
Launch, Pilot Onboarding & Handover
Week 6 covers go-live, a security review, full documentation, and onboarding your first pilot customer or internal ESG team. You get a full handover pack: architecture docs, a prioritised next-steps roadmap, and a recorded walkthrough for your own engineers.
Who This Is For
This service is built for founders and product teams who have a clear sustainability problem to solve but need a technical partner to build it fast. If you are building a marketplace for carbon credits, a proptech platform for green building certifications, or a SaaS tool that helps mid-size companies file their first CSRD report, we have built something similar before.
You do not need a technical co-founder to get started today. You just need a clear problem statement and a willingness to talk to real customers in weeks — not months. We handle everything from the first database table to the last line of deployment code.
Not sure if you are ready to build a first working version of your product? That is fine. Our free discovery call is designed to answer exactly that question in 30 minutes. No hard sell. Just an honest plan.

Frequently Asked Questions — CleanTech MVP Development
How long does it take to build a CleanTech MVP?+
Greta delivers CleanTech MVPs in 6 weeks from a signed contract and completed discovery workshop. This covers a working carbon tracking or energy monitoring product with core dashboards, data ingestion, and at least one automated report export. Complex IoT hardware integrations or multi-site deployments may add 2–3 weeks depending on sensor vendor API readiness.
Does the MVP support CSRD and TCFD reporting requirements?+
Yes. We design the data model and audit trail from day one to align with the GHG Protocol (Scope 1, 2, and 3), CSRD double-materiality disclosures, and TCFD climate risk frameworks. Your MVP will be able to export structured data in formats that feed directly into these disclosures, giving your compliance team a defensible chain of evidence.
Can you integrate with IoT sensors and smart meters?+
Yes. We have experience integrating with MQTT and REST-based IoT platforms, smart meter APIs (including SMETS2 in the UK), building management systems (BMS), and energy monitoring hardware from vendors such as Schneider Electric and Siemens. If your sensors expose a standard protocol, we can ingest the data into your MVP's monitoring dashboard.
What does a CleanTech MVP cost with Greta?+
CleanTech MVPs start from £15,000 for a focused carbon tracking or energy monitoring product with a core dashboard, one data source integration, and a basic reporting export. Scope 3 supply-chain modules, multi-site IoT deployments, and advanced ESG analytics modules are scoped separately. We provide a fixed-price quote after the discovery workshop.
What tech stack do you use for CleanTech products?+
We typically use Next.js or React for the dashboard frontend, Node.js or Python for the data processing backend, PostgreSQL or TimescaleDB for time-series energy data, and cloud infrastructure on AWS or GCP. For IoT ingestion we use MQTT brokers and serverless event pipelines. The full stack is chosen to match your team's existing capability and long-term hiring plan.
