Company profile
researched Aug 2026Manifest Climate is a Toronto-based software company that operates an AI assessment engine for sustainability and climate disclosure analysis. Customers select a set of organizations (portfolio companies, clients, members, suppliers or peers), the documents to be reviewed (sustainability reports, annual reports and filings, TCFD reports, proxy statements, policies and strategy documents), and a methodology — either their own custom criteria or a prebuilt framework such as CSRD/ESRS, ISSB (IFRS S1 & S2), TCFD, GRI, OSFI B-15 or California SB 261. The platform then extracts and assesses each datapoint, returning conformance determinations, verbatim supporting quotes with page-level citations, gap analysis, peer benchmarking and year-over-year trend views, with roll-ups from datapoint to topic to framework and from company to sector to portfolio.
The company also offers off-the-shelf assessment packages, including GHG Emissions Reporting (59 datapoints, 6 subtopics), Physical Climate Risk & Adaptation (39 datapoints, 6 subtopics), Net Zero & Transition Plan (70 datapoints, 5 subtopics), Supply Chain ESG Scorecard (306 datapoints, 9 subtopics) and Investor ESG Due Diligence (179 datapoints, 10 subtopics). Results can be reviewed in Manifest dashboards or connected to external AI assistants such as Claude, ChatGPT and Copilot, carrying the same findings and citations. Earlier product packaging described two modules, Manifest Compliance (AI-powered regulatory gap analysis, automated mapping, disclosure benchmarking) and Manifest Research (source-traceable ESG data on thousands of global publicly traded companies, a searchable disclosure database and an AI-powered ESG analyst).
At launch the platform was positioned as a climate intelligence "SaaS+" product built around alignment with the Task Force on Climate-related Financial Disclosures, including a TCFD Readiness Module that organized a company's climate-related information, identified maturity gaps, benchmarked disclosures against sector leaders and provided educational resources, legal and policy tracking, and curated monthly reports.
Founding story
Zizzo had spent more than a decade advising corporations and financial institutions on climate risk, and demand for those advisory services outgrew what her team could deliver manually across roughly 100 corporate clients. The company was created to do the same consulting-style analysis at scale through software, with co-founder Jeremy Greven, a software developer and entrepreneur who had advised startups through programs including the University of Toronto's Creative Destruction Lab and Ryerson's DMZ.
Business model
Manifest Climate sells a software platform (originally described as "SaaS+") to enterprises and institutions, positioned as a lower-cost, faster alternative to consulting engagements; customers run assessment projects against their chosen entity sets and methodologies, with scope confirmed via a balance of assessment units before a project runs.
Software subscription/project-based platform sales to enterprises and institutions, positioned against the cost of consultants.
Traction
Piloted with more than 15 public companies plus banks and asset managers before the 2021 seed round; by the 2022 Series A the platform was in use by organizations including Scotiabank, Manulife, Teck Resources, BentallGreenOak and Loomis Sayles. The company had about 30 employees at the time of the seed round and planned to grow past 50.
Latest developments
The current product is presented as an AI assessment engine supporting custom methodologies alongside CSRD, ISSB, TCFD, GRI, OSFI B-15 and SB 261, with prebuilt assessment packages, dashboard roll-ups, connectors to external AI assistants, and SOC 2 certification. Jim MacDonald is listed as CEO, with founder Laura Zizzo in a Founder & Strategy role.

Market position
Described in its 2022 Series A announcement as a leading climate intelligence SaaS+ platform, used by large financial, insurance, endowment and asset management organizations as well as real estate, mining, technology and packaged goods companies across North America and Europe; it was featured in the G20 Innovations League list of top cleantech start-ups.
Positioning emphasizes verifiable, auditable output: every finding is tied to verbatim source evidence with page-level citations, criteria are locked so assessments are repeatable and comparable, no developer work or prompt engineering is required, and the workflow is claimed to be roughly 200x faster than manual analysis with enterprise security controls.
Technology
An AI engine that ingests public or private corporate documents (including tables, footnotes and appendices), applies user-defined or prebuilt criteria, and extracts, triangulates and scores each datapoint, attaching verbatim quotes with page-level source citations. The company states 100% source-cited findings, 23% higher accuracy versus manual workflows, assessment of 100 entities in under two hours, SOC 2 certification, isolated environments and zero data retention options. Multilingual assessment is offered for regulators, and findings can be surfaced through connectors into third-party AI assistants.
Go-to-market
Direct enterprise sales via demo requests and 30-minute booked demos, including a proof-of-value offer to run a prospect's existing manual workflow on the prospect's own sources and criteria and compare results side by side with their current process.
Advisors and auditors; asset managers and asset owners (pre-investment due diligence, portfolio monitoring, stewardship and proxy voting); nonprofits and NGOs assessing members; public companies benchmarking peers and suppliers; and regulators and supervisors assessing regulated entities. Named users have included Scotiabank, Manulife, Teck Resources, BentallGreenOak, Loomis Sayles, First Capital and Transcontinental.
Geography
Headquartered in Toronto, Canada, with customers across North America, Europe and beyond; the seed-stage pilots involved companies in Canada, the US, Europe and Australia.
History
Laura Zizzo co-founded Mantle314 in 2015 as an interdisciplinary climate strategy firm. After five years, concluding that technology was needed to scale impact, she partnered with technology entrepreneur Jeremy Greven to create Manifest Climate, which began in 2020 as a sustainability consultancy and rebranded from Mantle314. The company piloted a TCFD benchmarking and maturity-assessment product with more than 15 public companies and with banks and asset managers in the US, Europe and Canada, raised a $6.5M seed round in February 2021 and a CAD $30M Series A in March 2022. The product has since been repositioned as a general AI assessment engine covering multiple sustainability frameworks, and the company is now led by CEO Jim MacDonald, with Laura Zizzo listed as Founder & Strategy.
