Corporate Impact

We work with companies to develop and implement strategies for maximising their social return on investment. We provide corporate philanthropy, CSR, employee volunteering, and partnership development advice.

When it comes to CSR, sustainability and community investment, companies have immense potential to create change both inside and outside their organisations. To get there, they must navigate diverse challenges, from developing strategies for social impact aligned with their core business, to balancing the needs and desires of a range of stakeholders, including shareholders, management teams, staff, and customers.

I.G. Advisors works with companies of all sizes to meet these demands with creative, differentiated strategies and realistic solutions.

We have worked with clients to design and launch corporate foundations and to establish charitable partnerships that meet both corporate targets and social objectives. We also work with CSR departments to refresh strategies, expand to new markets, or build buy-in from key stakeholders.

Create a CSR strategy that goes beyond just doing good. To find out how we can support your corporate team, please contact us.

We work with charities and social enterprises to diversify and sustainably grow their income. We have extensive major gifts, corporate partnerships, and campaigning experience.

Organisations with a healthy, diversified funding base are more likely to achieve their mission. For most charities and social enterprises, fundraising is essential, but this necessary activity can seem like a daunting task.

I.G. Advisors identifies step-by-step solutions to help charities achieve short and long-term fundraising goals. We have a deep understanding of the donor world and bring an active and realistic perspective to fundraising.

Our direct experience in working with both donors and fundraisers means that we know how to create sustainable income streams from major gifts, corporates, trusts, foundations and statutory funders. We can help you devise a fundraising strategy that appeals to your donors and also matches your ethos, capacity, and ambitions.

Our work includes developing innovative partnerships with corporate donors and building vehicles for strategic donor engagement. We also help social enterprises navigate challenges unique to creating profit within a social purpose. We can help you scale your business development activities while ensuring that you stay true to your social mission.

To ensure lasting solutions, I.G. Advisors provides coaching for senior staff in charities and social enterprises with a focus on fundraising and management.

Social Misfits Media

Our sister company helps charities and social enterprises design and implement vibrant digital strategies. They focus on helping clients use social media for marketing, campaigning, and fundraising purposes.

Social media has proven itself to be a sophisticated outreach tool for many organisations. Most charities and social enterprises now use social media to advocate, advertise, or launch appeals. But not every organisation does so effectively.

In 2012, I.G. Advisors launched Social Misfits Media to help charities and social enterprises think strategically about their digital presence. Social Misfits Media works with clients to create dynamic social media strategies for marketing, campaigning, and fundraising.

Specifically, Social Misfits Media runs bespoke social media workshops, designs social media strategies, manages social media accounts, and publishes a range of innovative guides.

Alisha F. Miranda, Managing Director

Alisha F. Miranda has focused her career on helping innovative programmes build scale and become sustainable. She has been advising I.G. Advisors since its founding in 2011 and joined the firm full-time in 2015 as Managing Director. Alisha brings to the team over a decade of experience in CSR, philanthropy and women and girls related work.

Most recently, Alisha was the Director of TrustLaw, the Thomson Reuters Foundation’s global pro bono service that helps NGOs and social enterprises in over 170 countries access pro bono legal support. In her first 18 months at the organization, Alisha grew the network by over 100% and launched two new products: a global index of pro bono and a training course on social enterprise and impact investing. She managed a large team of global staff and also supported the development of the Foundation’s annual Trust Women Conference.

Previously, Alisha managed global community investment at Standard Chartered Bank, where she designed the global expansion strategy for the Goal programme which gives adolescent girls in urban slums access to critical life skills and knowledge like financial literacy and reproductive health through sport. When Alisha joined the Bank in 2008, Goal was a small, expensive intervention, supporting just 49 girls. Using a culturally sensitive approach to girls’ issues and a robust business model that kept the programme integrity intact, Alisha launched a new strategy that eventually brought Goal into now 18 countries, with a target to reach half a million girls.

Alisha is a trustee of Coin Street Community Builders, Women Win, and an advisor to Lend-A-Hand India. She was previously a trustee of the UK National Committee for UN Women and member of the Global Reporting Initiative’s gender working group on the G3 Guidelines.
