What MainStreet Partners does
MainStreet Partners is an FCA-authorized (Reference Number 548059), London-headquartered sustainable investment advisor founded in 2008 by Rodolfo Fracassi and Andrea Carati. The company serves institutional clients — Wealth Managers, Asset Managers, Investment Banks, and Institutional Investors — with a dedicated ESG offering organized into two service lines: ESG Advisory (financial analysis, portfolio construction, and impact investment selection targeting UN Sustainable Development Goals) and Portfolio Analytics (Fund Sustainability Ratings, bespoke sustainability intelligence aligned with green regulations, and partner portfolio ESG evaluation). Underpinning the offering is a proprietary ESG platform (esgeverything.com) and a set of documented scoring methodologies — Corporate ESG Scoring (12 categories, monthly reviews), Country ESG Model (88 indicators), GSS Bond Rating, Funds ESG Rating (3-pillar, 100+ indicators, 4-eyes review), and SDG Alignment Model — covering 150+ managers, 2,000+ funds, and over 9,500 strategies. Portfolio Analytics is delivered through four integrated sub-modules: Framing, Scoring, Measuring, and Reporting.
The business model is B2B and primarily subscription- and advisory-driven: recurring revenue from portfolio analytics subscriptions and platform access, professional services revenue from custom advisory and research engagements, and indirect revenue from the annual ESG Champions Awards program, the ESG & Sustainability Barometer, and the GSS Bonds Market Trends Report, which double as thought-leadership marketing. Pricing is quote-based enterprise engagement; no public pricing or revenue figures are disclosed. Distribution is a hybrid of direct enterprise sales and self-service access via esgeverything.com, supplemented by PR, LinkedIn, and ongoing media coverage in financial publications.
Since 2023 the company has operated as a controlled subsidiary of Allfunds Group (65% stake acquired in 2022, closed early 2023), with Banca Generali holding 10% and management retaining 25%; the firm maintains its brand and operational independence. In October 2025, Neill Blanks succeeded founder Rodolfo Fracassi as CEO, marking the first external leadership transition.

MainStreet Partners product offering
Product offeringCore offering
MainStreet Partners is an independent sustainable investment advisor offering ESG Advisory (financial analysis, portfolio construction, and selection of impact investments targeting UN Sustainable Development Goals) and Portfolio Analytics (transparent fund sustainability ratings and bespoke sustainability intelligence aligned with green regulations) to institutional investors. The offering is supported by proprietary ESG scoring methodologies covering corporates, countries, funds, GSS bonds, and SDG alignment, delivered through a dedicated ESG platform at esgeverything.com.
Product overview
MainStreet Partners operates as an independent, dedicated Sustainable Investment Advisor founded in 2008, offering a one-stop shop for sustainability requirements at portfolio level. The core offering consists of two main service lines — ESG Advisory (covering financial analysis, portfolio construction, and impact investment selection) and Portfolio Analytics (delivering fund sustainability ratings and bespoke sustainability intelligence aligned with green regulations). Portfolio Analytics is structured as an integrated platform comprising four sub-modules: Framing (exclusion and policy design), Scoring (proprietary fund and government bond ESG ratings across 150+ managers and 2,000+ funds), Measuring (SDG alignment, EU Taxonomy, and sustainability metrics), and Reporting (impact reports classifying bonds by use of proceeds and UN SDG alignment with quantified environmental and social outcomes). Supporting the platform are several proprietary methodologies — the Corporate ESG Scoring Methodology (12 key categories, monthly reviews), the Country ESG Model (88 indicators across four pillars), the GSS Bond Rating Methodology (issuer and issuance evaluation), the Funds ESG Rating Methodology (3-pillar, 100+ indicators), and the SDG Alignment Model — each serving as the analytical backbone of the product suite. The company also publishes recurring research products including the ESG & Sustainability Barometer, the GSS Bonds Market Trends Report, and the annual ESG Champions Awards program. A consumer-facing digital interface is provided via the ESG Platform at esgeverything.com. The company is majority-owned by Allfunds Group (65%) following a 2022 acquisition, with management retaining a 25% stake and Banca Generali holding 10%.
