GreenFortune

GreenFortune Windows and Doors, established in May 2022 by co-founders Dilip Kumar and Pratyusha Kosaraju, is targeting India's fenestration market. The company was founded to address a gap in the market for high-quality, yet affordable, windows and doors specifically designed for Indian climatic conditions, particularly for middle-income consumers. Kumar, previously a partner at BCG advising building material companies, identified this market need, leading him and Kosaraju to launch the Hyderabad-based venture.

The company operates on a hybrid B2B and B2C model. It supplies uPVC profiles and other raw materials to a network of over 150 fabricators across India, who then create and install the final products. Simultaneously, GreenFortune serves end-customers directly, including individual home builders, larger developers, and institutional clients like schools and colleges. This B2B2C approach allows the company to maintain brand and quality control while leveraging the reach of local partners. Revenue is generated from the sale of these window and door systems. As of March 2024, the company reported an annual revenue of ₹9.32Cr.

GreenFortune's core offering consists of uPVC windows and doors, manufactured in ISO-certified facilities in India, Germany, and Japan. The products are specifically designed by an in-house R&D team to withstand India's diverse climates. The company offers a range of customizable uPVC profiles and plans to expand its product line to include aluminum, steel, and wooden doors. A key differentiator is its proprietary technology platform, PartnerGate™. This full-stack solution enables fabricator partners to design products, generate a bill of materials, create professional quotations, and manage orders, thereby improving efficiency and service quality.

Since its inception, the company has shown significant traction, supplying materials for over two million square feet of installations across more than 100 locations in India. Financially, GreenFortune has successfully raised a total of $9.13M in capital over three funding rounds. Its latest seed round in March 2025 brought in $4.5 million, led by Foundamental, to fuel national expansion, increase production volume, and further develop the PartnerGate platform.
