We built Circulyft because the ESG reporting market was broken — and we'd been inside it long enough to know exactly how.
In 2022, Natasha Rivera had spent three years as sustainability lead at a Tier 1 auto supplier in Metro Detroit, trying to produce defensible Scope 3 data with a rotating cast of consultants who changed their methodology each engagement. The data was fragmented across 40-plus systems — ERP, freight manifests, utility invoices, supplier forms — and each year's report still came back with audit findings on source documentation. The Big Four charged for the problem as much as the solution. We founded Circulyft to build the tool she needed and couldn't find anywhere.
"Make accurate, auditable Scope 1-3 emissions data accessible to every mid-market manufacturer and retailer — not just those who can afford a Big Four engagement and six months of calendar time."
Three co-founders — industrial sustainability, environmental engineering, and data infrastructure
Spent three years as sustainability lead at a Tier 1 automotive supplier in Metro Detroit, managing CSRD predecessor reporting and trying to produce defensible Scope 3 data across a 200-supplier base. Each engagement started from scratch. Founded Circulyft in 2022 because the tool she needed didn't exist.
Environmental engineer with eight years at an automotive OEM's sustainability operations group in southeast Michigan, where he built the internal Scope 1-3 calculation tooling that the company actually used for regulatory filings — EPA-factor integration, dual-method Scope 2, all 15 GHG Protocol Scope 3 categories. At Circulyft, he rebuilt that rigor as a productised SaaS calculation engine that doesn't require a PhD to run.
Built data integration infrastructure at a logistics data platform serving mid-market shippers for six years — REST API design, carrier feed normalisation, ERP connector architecture across SAP and Oracle environments. Brought that integration layer to Circulyft. The reason Circulyft connects to your freight carrier and your ERP without a six-month IT project is Maya's architecture.
Why Detroit
Detroit is the center of gravity for US manufacturing — automotive assembly, Tier 1 and 2 parts suppliers, industrial logistics, and the supply chains that connect them. It's also the sector where the CSRD and SEC climate disclosure transition lands hardest: high Scope 1 combustion from manufacturing processes, complex multi-tier Scope 3 value chains, and supplier bases that have been running for decades without emissions data attached.
That's not an abstract market analysis for us. Our customers are the plant sustainability managers and CFOs in the buildings around us. We understand the operational reality of legacy ERP configurations, shift-based production schedules that don't align with calendar-year reporting, and 200-supplier bases where 30% never respond to your first questionnaire. We built for those constraints from day one, not as a future roadmap item.
Angel-funded and growing. We're focused on building the right product for mid-market manufacturers facing real compliance deadlines — not on optimising for another funding announcement. When we raise again, it will be because we've proven the model with customers who file real ESG reports using Circulyft data, not because we hit an arbitrary calendar milestone.
Facing a CSRD or SEC deadline with fragmented data? Let's talk.
If you're a manufacturer or retailer with a CSRD FY 2025 filing or SEC climate disclosure requirement coming up, we want to hear about your data environment — utility systems, ERP, carrier feeds, supplier base. In 30 minutes, we'll show you what your inventory looks like from your actual data.
