What Addidat does

Addidat Limited is a UK-based, employee-owned professional services firm that provides outsourced ESG (Environmental, Social, and Governance) strategy, communications, delivery, and reporting support to UK growth companies and their investors, with a particular focus on AIM-listed and small-cap firms. The company was founded in 2022 by Nina Spencer (CEO) and operates from London (Battersea Power Station), with a registered office in Magdalen Laver, Essex. Addidat is female-founded, with over 50% of management positions held by women, and operates an 11-50 employee team structured around CEO, Chief Client Officer, Chief Product Officer, Director of Engineering, and Client Director functions.

The core of Addidat's offering is a two-part model: the proprietary Addidat Platform — a data and analytics platform built on a proprietary dataset covering all AIM participants and UK small-cap companies — paired with bespoke advisory services delivered on a quote-based, annual engagement model. The platform enables data-driven ESG benchmarking and decision support, while the advisory layer covers TCFD reporting, ESG strategy development, board-level facilitation, and stakeholder communications. Clients span listed PLCs (Costain, Young & Co's Brewery, Craneware, Tracsis, Oxford Metrics, Calnex, LendInvest, Aminex, Michelmersh, Carr's Group, CPP Group, accesso, Concurrent Technologies), asset managers (Gresham House Asset Management), consultancies (LACE Partners, Alpha Financial Markets Consulting, 4most), and government/nonprofit entities (Commonwealth War Graves Commission, Trinity House). Addidat also produces annual collaborative research with Indigo: Independent Governance on gender diversity in AIM boards and participates in industry events such as the AIM Awards.

The go-to-market is sales-led, anchored by direct expert calls booked via Calendly, supported by thought-leadership content, an email newsletter, and research reports. The company holds Cyber Essentials certification, Living Wage Foundation accreditation, and is a member of the Quoted Companies Alliance. Geographic scope is the United Kingdom only, with no global footprint claim. Pricing is not publicly disclosed; engagements are tailored, scalable up or down with client demand, and billed annually under a custom professional services model.

Direct peers

• EcoAct (an Accenture company): EcoAct provides climate and ESG strategy, reporting, and advisory services to corporates, closely overlapping with Addidat's outsourced ESG service line. Addidat's niche (UK small-cap and AIM) and EcoAct's broader enterprise focus differ in target customer, but both compete for ESG advisory budgets.
• Carbon Trust: Carbon Trust is a UK-headquartered climate and sustainability advisory firm offering strategy, disclosure, and net-zero advisory to corporates and financial institutions. It is comparable to Addidat as a UK-based ESG advisory provider serving regulated businesses, though Carbon Trust's services are broader and larger in scale.
• Sustainalytics: Sustainalytics is a dedicated ESG data, ratings, and research provider serving asset managers and corporates globally. Like Addidat, it combines proprietary ESG datasets with advisory/research output; however Sustainalytics targets large-cap and global issuers whereas Addidat specializes in UK small-cap and AIM.
• Anthesis Group: Anthesis is a global sustainability consulting firm providing ESG strategy, reporting, and climate advisory to corporates. Like Addidat, it sells outsourced ESG advisory to mid-market and growth companies, though Anthesis operates at significantly larger scale and broader international footprint.
• Baringa Partners: Baringa Partners is a UK-based management and technology consultancy with a dedicated climate and sustainability practice serving financial services and corporates. It overlaps with Addidat's strategy and ESG advisory offering in the UK market, though Baringa operates more broadly across financial services consulting.
• ISS ESG: ISS ESG provides ESG data, ratings, and advisory services to investors and corporates worldwide. It is directly comparable to Addidat in offering both proprietary datasets and ESG advisory; Addidat differentiates via its narrow focus on UK small-cap and AIM-listed companies.
• FTSE Russell (ESG data & indices): FTSE Russell builds ESG indices and provides ESG data and analytics used by UK asset managers and issuers. It is comparable to Addidat as a UK-relevant ESG data provider, but FTSE Russell serves global large-cap markets whereas Addidat targets the UK small-cap/AIM segment.

Broad incumbents

• MSCI ESG Research: MSCI ESG Research is a large global ESG data and ratings provider, broadly comparable to Addidat's data offering to asset managers. It is a broad incumbent serving global institutional investors with extensive large-cap coverage, whereas Addidat's proprietary dataset focuses specifically on UK small-cap and AIM issuers.
• PwC UK (Sustainability & Climate): PwC UK's sustainability practice offers ESG strategy, reporting, and assurance services to UK corporates, competing for the same TCFD and sustainability disclosure budgets that Addidat targets. As a broad incumbent, PwC covers FTSE-level and large-cap clients; Addidat carves out the small-cap and AIM segment PwC tends to underserve.
• KPMG UK (Sustainability Services): KPMG UK's sustainability services practice provides ESG advisory and assurance to UK listed companies. It is comparable to Addidat's outsourced ESG advisory offering, with KPMG targeting larger FTSE-listed clients and Addidat specializing in proportionate support for resource-constrained small-cap and AIM issuers.
