  • Risk Mitigation for Transactions
    By conducting environmental due diligence, the company can help clients identify potential environmental liabilities before mergers, acquisitions, or property transactions, reducing financial and legal risk.

Possible disadvantages

  • Limited Brand Recognition
    As a newer or lesser-known provider compared to Google Workspace or Microsoft 365, StackMail may lack the trust and reputation that larger providers have established.
  • Fewer Third-Party Integrations
    Compared to major email service providers, StackMail may offer fewer integrations with third-party apps and services, limiting its versatility for some businesses.
  • Limited Advanced Features
    It may not offer the same breadth of advanced productivity and collaboration tools that come bundled with larger platforms like Microsoft 365 or Google Workspace.
  • Smaller User Community
    Due to a smaller user base, there may be fewer community resources, third-party tutorials, or troubleshooting forums available online.
  • Uncertain Long-Term Support
    As a smaller company, there might be concerns regarding the long-term viability, updates, and continued support of the service compared to more established providers.

Questions & Answers

As answered by people managing EcoDiligence and StackMail.

Who are some of the biggest customers of your product?

EcoDiligence's answer

EcoDiligence recently launched publicly. We're onboarding early SME suppliers, consultants and accounting firms across Europe, Australia and Southeast Asia. Named customers will be listed here once public references are in place.

Why should a person choose your product over its competitors?

EcoDiligence's answer

Three reasons: Purpose-built for the buyer-request problem. Most ESG platforms are carbon-accounting tools with reports bolted on. EcoDiligence starts from the disclosure a buyer will ask for and works backward. VSME- and ISSB-aligned in the same profile. One data model covers European buyers (VSME) and global capital markets (ISSB IFRS S1/S2) — with country-specific packs for Australia (AASB S2), the US (California SB 253/261), Japan (SSBJ), Singapore, India, Brazil and more. Structured outputs, not just PDFs. The EFRAG VSME XLSX workbook and XBRL instance are produced natively, so the disclosure is machine-readable by buyer systems and auditor tools — without a consultant re-entering data. The result: an SME can respond to a large customer's request in a single sitting instead of paying for weeks of consulting.

What makes your product unique?

EcoDiligence's answer

EcoDiligence produces a single, structured ESG profile — an "ESG Passport" — that answers every buyer request at once, aligned with the EU VSME standard and ISSB IFRS S1/S2. The Passport is generated in three formats: a branded PDF report, the official EFRAG VSME XLSX workbook (v1.3.0), and an XBRL instance. Very few tools in this space produce the digital VSME and XBRL outputs directly; most stop at PDF. Built for SMEs pulled into disclosure by their large customers — not for enterprises with a dedicated sustainability team.

How would you describe the primary audience of your product?

EcoDiligence's answer

Three audiences, in this order: SMEs and suppliers — companies with roughly 10–1,000 employees that have been asked by a large customer, bank or exporter to provide sustainability data. Typical caller: a CFO, operations lead or founder without an in-house ESG function. Consultants and advisors — sustainability consultants, accountants and bookkeepers who serve multiple SME clients and need a repeatable way to produce disclosures for them. Enterprise and procurement teams — larger buyers that want to receive structured, comparable disclosures from their SME suppliers instead of chasing bespoke spreadsheets.

What's the story behind your product?

EcoDiligence's answer

EcoDiligence was built after seeing the same pattern repeat: a large buyer sends its SME supplier a sustainability questionnaire, the supplier has no in-house team, and the choice becomes either paying a consultant thousands or answering incompletely and risking the contract. The EU's VSME standard was designed precisely to fix this — a proportionate, standardised disclosure that a small company can produce once and reuse everywhere. EcoDiligence turns that standard into working software, and extends the same idea to ISSB and to jurisdiction-specific frameworks in Australia, the US, Japan, Singapore, Brazil and beyond.

Which are the primary technologies used for building your product?

EcoDiligence's answer

Next.js 15 with TypeScript (strict) Supabase (Postgres, auth, storage) Clerk Organizations Anthropic Claude (assisted disclosure drafting) Paddle (billing, Merchant of Record) react-pdf/renderer for PDF output JSZip / TypeScript core for the EFRAG VSME Digital Template (XLSX) Native XBRL generation aligned with the EFRAG VSME taxonomy Resend, PostHog, Sentry, Upstash Redis Deployed on Vercel
