Possible disadvantages

  • Cost
    The platform can be expensive for small and medium-sized businesses, limiting its accessibility to larger organizations with bigger budgets.
  • Learning Curve
    Though user-friendly, there may be a learning curve for new users, especially those not familiar with technical hiring tools.
  • Limited Candidate Pool
    Since users need to have some level of coding proficiency to perform well, it might not be suitable for assessing candidates who are just starting out or are from non-technical backgrounds.
  • Potential for Overfitting
    Candidates familiar with CodeSignal's specific types of questions and problems may perform better, which might not always reflect their overall coding abilities.
  • Internet Dependency
    As a cloud-based platform, it requires a stable internet connection, which might pose challenges in regions with limited connectivity.
  • Sustainability-focused concept
    The name TrackZero.eco suggests a tool for tracking environmental impact, such as carbon emissions, toward a net-zero goal. I could not access the site, so this is inferred from the name and domain and not confirmed by its content.
  • Possible measurement and visibility
    Tools in this category usually let users measure their footprint and see where emissions come from. Check the site to confirm whether TrackZero offers dashboards, reports, or goal tracking.
  • Potential support for reduction goals
    Platforms like this often help users set targets and monitor progress. Whether TrackZero does this, and how well, needs to be checked on the site.

Questions & Answers

As answered by people managing CodeSignal and TrackZero.eco.

Who are some of the biggest customers of your product?

TrackZero.eco's answer:

  • Bridgestone Tyres
  • Volkswagen Group UK
  • Synergy Logistics
  • Milton Keynes Council
  • Robinsons Packaging plc

How would you describe the primary audience of your product?

TrackZero.eco's answer:

TrackZero is built with four different audiences in mind:

  • SMEs and mid-market UK businesses facing procurement pressure, tender requirements, or investor questions on emissions. Often producing their first proper carbon inventory.

  • Sustainability, finance and procurement leads at larger UK organisations who need audit-ready reporting for SECR, UK SRS or CSRD without a six-figure consultancy engagement.

  • Carbon consultants and ESG advisors who run client portfolios and need a platform their clients can also use directly, so the work isn't locked to one relationship.

  • Public sector suppliers meeting PPN 006 requirements to bid for NHS or central government contracts over £5 million.

Sectors range across construction, engineering, manufacturing, financial services, food and drink, professional services and technology.

What makes your product unique?

TrackZero.eco's answer:

TrackZero is the UK-built carbon management platform simple enough for in-house teams without the expertise, and powerful enough for experts to work smarter without the cost. Four things set it apart from the crowded field of US and Nordic platforms:

  • UK-native by design. SECR, UK SRS, PPN 006 and CSRD reporting are built in, not bolted on. Every output maps to a real UK obligation, so finance teams can hand a report straight to their auditor.

  • Collaborative supply chain engagement. Scope 3 is the hardest part of any inventory. TrackZero turns it into a network effect: your suppliers use the platform to submit primary data on their own footprint and the goods and services they sell you. That data flows into your inventory automatically, replacing spend-based estimates with verifiable primary figures.

  • You keep the platform, whoever runs it. Use TrackZero yourself or bring in a carbon consultant. If you change consultants, you keep the platform and every year of data in it. .

  • Priced to stay affordable at any scale. From SMEs producing a first footprint to listed PLCs preparing for external assurance, the pricing works. No enterprise minimums, no consultancy-tier gatekeeping.

Why should a person choose your product over its competitors?

TrackZero.eco's answer:

Because TrackZero delivers what most carbon platforms only promise: audit-ready numbers without the enterprise price tag, consultancy tie-in or the hidden calculations.

Compared with the big US and Nordic platforms, TrackZero is built for UK regulatory reality first: PPN 006 for public procurement, SECR for large companies, UK SRS for the incoming disclosure standard, and CSRD for UK subsidiaries of European groups. Every calculation is transparent, so auditors review evidence directly in the platform rather than rebuilding numbers.

Compared with free tools, TrackZero adds multi-year tracking with year-specific emission factors, market-based Scope 2, full supplier engagement for primary Scope 3 data, and ISO 27001 certified security.

Compared with the "carbon consultant with a spreadsheet" approach, TrackZero gives you a platform you own. Change consultants without changing tools.

What's the story behind your product?

TrackZero.eco's answer:

TrackZero was founded in October 2023 by people who had done this before. Alan Wilson (CEO) co-founded MoreTrees, acquired by THG PLC within six months of launch. Alan also co-founded Expandly, acquired by GEE. Oliver Waters (CPO) founded Momento, named Apple's App of the Year Runner-Up in Europe. And, Steven Waterfall (CTO) brought engineering leadership from multiple startups.

The idea came from conversations with sustainability, procurement and supply-chain teams through 2023. The same story kept coming up: enterprises sending carbon questionnaires suppliers didn't understand, consultants too expensive to scale and data too inconsistent to act on. One logistics business had lost a contract because it couldn't answer a carbon questionnaire during procurement. Carbon reporting had turned into a condition of doing business, and no one had built the infrastructure to make it work for both sides.

Cranfield University came in early as strategic advisor, pre-seed investor and eventually a customer through its Ready for Net Zero programme. Their sustainability academics validated the methodology against GHG Protocol standards and DEFRA emission factors before the first enterprise customer signed on.

Development began January 2024. The first commercial version launched in March 2024. Bridgestone Tyres signed early and Volkswagen Group UK followed. Today TrackZero boasts organisations from FTSE-listed manufacturers to sole traders and city councils.

Which are the primary technologies used for building your product?

TrackZero.eco's answer:

TrackZero is built entirely in-house by the Track Zero Labs engineering team, led by CTO Steven Waterfall. Nothing is white-labelled, and no part of the carbon-accounting engine is licensed from another provider.

At the core is our proprietary emissions calculation engine, aligned strictly to GHG Protocol standards. Cranfield University's sustainability academics validated the calculation framework against those standards and against DEFRA emission factors before the first enterprise customer came on board.

The platform is a web-based SaaS running on cloud infrastructure, engineered to ISO 27001 information security standards. Every calculation is fully traceable, so auditors and finance teams can review evidence, methodology and figures directly in the platform rather than rebuilding numbers from scratch.

Building the engine ourselves rather than licensing one gives us three things: full control over how methodology evolves as standards update and the ability to expose the workings to customers and auditors instead of hiding it.
