What Sumday does

Sumday is an Australian AI-native software company (legal entity Local Carbon Pty Ltd, headquartered in Tasmania) that builds decision infrastructure for finance, FP&A, procurement, and sustainability teams. Its core product, Sumday Carbon, is an audit-ready GHG accounting platform featuring a carbon ledger that links emissions data directly to financial transactions, AI-powered transaction classification with confidence scoring, automated Scope 3 supplier engagement, and pre-loaded Supplier-Specific Emission Factors traceable to original supplier disclosures. The platform generates draft climate disclosures compliant with ASRS/AASB S2, ISSB, CSRD, TCFD, and NGER requirements, and is built on Microsoft Azure with Auth0-based SSO, ISO 27001, and SOC 2 Type II certifications.

The company has expanded beyond carbon into adjacent workflows with Sumday Procurement (AI-driven approval workflows, scope-of-work drafting, and vendor evaluation) and Sumday Projects (structured tender processes and milestone-based reviews), plus a services portfolio covering AI & Agents, Procurement, Sustainability, FP&A, and CapEx & PMO. Sumday Academy provides embedded training, and SumdAI is an in-product assistant grounded in GHG Protocol methodology. Founded by ex-PwC auditors including CEO Jess Richmond and Co-Founder Lindsay Ellis (CPA, HEC Paris Master's, PwC audit background), the company leverages its Big-4 audit heritage to differentiate on accounting-grade rigor.

Sumday's go-to-market combines product-led growth via a flagship Xero partnership (free 12-month access to 4+ million Xero SMBs globally, with approximately 70% of carbon reporting data sourced from Xero accounts) with enterprise field sales targeting Australian mid-market and large organisations in financial services, telecommunications, retail, automotive, manufacturing, and government. Revenue is generated through subscription SaaS fees, professional services for AI transformation and implementation, and technical support engagements. The company has raised approximately $4.7M-$5.3M across two seed rounds (March 2023 led by Blackbird Ventures; April 2024 led by Planeteer Capital) with participation from Blackbird, Planeteer, Wedgetail, Possible Ventures, Saniel Ventures, and Cameron Adams (CPO at Canva).
