Caspian Debt — formally Caspian Impact Investments Private Limited — is the lending arm of Caspian Impact Investment Adviser, one of India's earliest impact investors, in business since 2004. The Hyderabad-based group reports roughly Rs 700 crore in assets under management, 29 direct equity investments, 3 fund investments and 17 exits, with a mission of aligning profit with purpose.

The group's thesis: finance enterprises whose business models embed social or environmental outcomes — from financial inclusion to climate and agriculture. Its track record spans the Bellwether Microfinance Fund (India's first domestic pool dedicated to early-stage microfinance equity and debt), the India Financial Inclusion Fund, and its debt arm. Active initiatives include the Caspian SME Impact Fund and the Caspian Leap for Agriculture Fund (LeAF), which invests along the agricultural value chain. The founder's note is explicit: having spent its first decade on financial inclusion and its second deepening agri and climate expertise, Caspian now prefers sectors where impact is embedded in the business model itself.

Caspian Debt itself is an NBFC launched in 2013 and the group's third fund. It extends term, working capital and subordinated loans — ticket sizes of Rs 0.5–15 crore (and a granular book of Rs 0.05–0.20 crore), tenures of 0.5–5 years — to fast-growing, early-stage impact enterprises that would otherwise be forced to grow through dilutive equity. Focus sectors include small business finance, microfinance, food and agriculture, affordable healthcare, clean energy, affordable housing and financial inclusion enablers; the DFC-backed facility specifically targets energy, healthcare, critical infrastructure and technology.

The numbers tell the story: the larger group says it has invested over Rs 2,000 crore through four funds, and Caspian Debt alone has funded over 140 companies across India — including Capital Float, EduBridge, Drishti and Aviom India Housing Finance. Its speciality is first-generation social entrepreneurs who struggle with banks because of no collateral and asset-light models: loans are customised and collateral-free. In 2020 it raised $20 million (Rs 151.14 crore) in long-term debt from the US International Development Finance Corporation (US DFC), committing a third of that facility to women-centric businesses under the 2X Women's Initiative. Earlier, the group's debt fund was seeded with $10 million from FMO, Triodos, Gray Ghost Microfinance Fund and others.

Key people: founder and MD S Viswanatha Prasad leads Caspian Debt. The firm runs no accelerator, but its collateral-free, impact-first debt products are themselves the credits perk for mission-driven SMEs.

Why it matters for founders

If you are a first-generation social entrepreneur whose bank keeps asking for collateral, Caspian Debt's collateral-free working capital and term loans (Rs 50 lakh–Rs 15 crore) — and its deep impact-finance network — make it one of India's friendliest doors for mission-driven SMEs.
