Illumine-i

What Illumine-i does

Illumine-i is a sustainable power engineering and grid integration firm that delivers design, owner's engineering, independent engineering, project management, and development consulting services for solar, battery energy storage systems (BESS), EV charging stations (EVCS), microgrids, substations, and power delivery infrastructure. Its service portfolio spans residential, commercial and industrial, community, and utility-scale projects, with project sizes reportedly ranging from residential rooftop systems to facilities exceeding 500 MW. The firm was founded in 2015 in Chennai, India, by Nithish Sairam and Sudarsan Krishnan (former Tesla, Sunrun, NextEra Energy, and OneRoof Energy employees) and has since expanded to a multinational footprint with headquarters in Austin, Texas, and additional offices in Chennai and Pune, India, serving customers across North America, India, and Australia.

The company's underlying technology stack combines a team of licensed Professional Engineers across multiple US states with an integrated suite of proprietary digital tools branded as IVE (client/project portal), SiteScribe (field survey), Evolve (automated EVCS proposal generation), GeoSift (property intelligence), Endore AI (construction document intelligence and BOM extraction), LoadCentral AI (panel schedule and SLD automation), and Thrive (vendor PM portal). It cites a 97% Authority Having Jurisdiction (AHJ) approval rate, 200K+ projects delivered, 3+ GW of clean energy engineered, and 700K+ consulting hours as cumulative operating evidence, and markets an explicit independent positioning (no equity stake, no EPC relationship, no equipment vendor ties) for its lender-facing independent engineering work.

Illumine-i generates revenue through project-based, quote-driven engineering services sold via enterprise field sales to solar developers, EPCs, IPPs, asset owners, and lenders, complemented by a direct website consultation channel and a third-party marketplace listing (Raiven) for SMB EPC buyers. Customers span six segments (Solar Developers, EPCs, Lenders/Institutional Investors, IPPs, Property and Asset Owners, and C&I Facilities), with 300+ solar installers/developers/EPCs and 100+ property/asset owners in the active base. The firm raised $2 million in Series A funding from Anicut Capital in February 2024, supports over $2 billion in clean energy transactions through its independent engineering work, and was recognized among the Forbes India DGEMS Select 200 Companies with Global Business Potential in 2023.
