Here are some changes that can help build a robust impact investing ecosystem in India:Move from qualitative to quantitative dataReporting impact data so far has mostly focused on qualitative and anecdotal data in narrative and case study formats. But to mobilise capital towards the sector, it is imperative to develop methodologies and indicators both on financial returns and social impact. This can help drive early-learnings within and across portfolios, attract additional capital, and present comparisons and trends.Document results consistentlyInvestors and investees can be more consistent in the way they document impact and measure data, taking care of aspects such as key assumptions applied, units of measurement, and so on. Creating and promoting an online public database, which houses guidelines and documentation protocols, can further facilitate the impact investment market.Ease the entry of funds into IndiaFunds based in India are subject to unfavourable laws that change often, with little to no prior notice. There is also concern over policies and regulatory requirements that differ across states, making compliance more difficult, as well as over the lengthy judicial process in India. As a result, global fund managers are often wary of establishing funds in India, or investing in Indian enterprises.There is a need for the government to step in and regulate the market through policy interventions.Enable the growth of intermediariesThere has been a growth in new types of organisations that support impact investors and social enterprises. For instance, intermediaries such as Unitus Capital help broker deals between funds and enterprises, and incubators such as Unltd India and Villgro provide support to enterprises early on in their lifecycle. These players play a critical role in facilitating the growth of the impact investing market.Increase collaboration amongst investorsFormal collaborations among impact investors offer benefits of shared lessons, costs, and databases. While Indian impact investors reported that they consulted co-investors during due diligence phases of investments, a similar process can be undertaken when impact reporting requirements are determined as well. Leveraging industry players, such as nonprofits active in the field and government agencies, can help coordinate research and learnings.
