After 12 months of strategic mentorship, expert advisory, and tailored support, fuelled by S$1 million in catalytic funding, the 2024 cohort of the Amplifier — a global mentorship programme co-developed by the Centre for Impact Investing and Practices (CIIP) and the Philanthropy Asia Alliance (PAA) — came together in Singapore in May 2025 for their showcase and reflection week.
It was a milestone moment for the five mentee organisations — Circ, GRST, MAYANI, MYCL, and Sampangan — to reflect on their impact and learnings, mark the culmination of their year-long journey with the programme, and take stock of what’s needed to scale their impact even further. The sessions also provided an opportunity to present the three new thematic tracks for the upcoming 2025 cohorts.
In the past year, with the support of 34 partners, the inaugural cohort of mentees had been matched with 20 mentors and received over 250 hours of tailored training, mentorship, and advisory support. Through recoverable grant funding supported by Mastercard Center for Inclusive Growth, they collectively unlocked over US$4 million in revenue and served more than 890 clients across both B2B and B2C markets.

Over the course of a dynamic week in Singapore, the mentees brought their innovations to the fore, showcasing solutions in sustainable agriculture and inclusive livelihoods, circular business models and waste management, emissions reduction, and more.

A highlight of the evening was the panel discussion with the mentees. Candid and energised, the innovators shared their motivations for joining the programme, their main takeaways, what was next for each organisation, and the types of partners they were looking for. They also offered peer advice to prospective Amplifier applicants.

(Clockwise from top left) On the panel were Ms. Annisa Wibi of MYCL, Mr. JT Solis of MAYANI, moderator Mr. Akhil Khurana from CIIP, Mr. Luke Henning of Circ, Mr. Frank Harley of GRST, and Ms. Hana Purnawarman of Sampangan.
Key takeaways from the panel include:
- Clarify and focus: Mentorship helped them prioritise effectively, distilling broad ambitions into clear, actionable strategies and making better decisions on where to focus their time and resources.
- Strategic networks: Regular engagement with mentors and ecosystem partners surfaced new opportunities, sharpened their value propositions, and built regional insight.
- Catalytic support: Both funding and guidance played a pivotal role in enabling product development, market access and expansion, and organisational growth.
- Mindset shifts: The mentees highlighted the value of embracing feedback, building trust-based relationships, and maintaining discipline through uncertainty.
- Paying it forward: There was a shared commitment to paying it forward and supporting fellow changemakers in the ecosystem, to contribute to a collaborative impact community.

From Complexity to Clarity: Communicating for Impact
A few of the Amplifier 2024 mentees joined a hands-on workshop on communicating complex ideas to diverse stakeholders — an essential skill for impact entrepreneurs engaging a wide range of target audiences which may include policymakers, funders, farmers, corporate partners, suppliers, distributors, and consumers.
The session explored how to better understand and segment stakeholder groups through tools like stakeholder analysis and network mapping, and consider factors such as the stakeholder’s concerns, fears, and aspirations.
Participants tried their hand at applying techniques to simplify complex concepts, structure compelling messages, and use storytelling tools such as visual aids, to bring their work to life.
The session also covered practical strategies for engagement — from crafting concise, tailored messages to overcoming common communication barriers. It offered a fast-paced yet thoughtful environment for sharpening how impact leaders could connect, persuade, and build alignment across their ecosystems.
Spotlight on Innovation: Taking the Stage at PAS 2025
One of the most energising moments of the Amplifier showcase and reflection week unfolded at the Innovation Spotlight session at the Philanthropy Asia Summit (PAS) 2025. In an action-packed session, each mentee took centre stage to pitch their bold solutions to a global audience.
With a packed room of changemakers, funders, and thought leaders across the public, private, philanthropic, and people sectors, the atmosphere was charged with curiosity and ambition. In just a few minutes, delivered in a TED Talk-style format without presentation slides, each founder shared the challenge they are tackling, the progress they have made, and their vision for what is next.
Circ’s Chief Business Officer Mr. Luke Henning kicked off the session by presenting its breakthrough in textile circularity. The company’s patented technology enables the recycling of blended materials, which has been a longstanding barrier in circular fashion, by recovering both synthetic and cellulosic fibres for reuse and reintroducing them into the textile supply chain.
"Fundamentally, through recycling, we have all the clothes we need to make all the clothes we will ever need."
— Mr. Luke Henning, Circ
GRST manufactures batteries that are non-toxic, fast-charging, and easily recyclable. Chief Strategy Officer Mr. Frank Harley highlighted their innovation in a water-soluble binder — the material used to adhere active materials to battery electrodes.
Unlike conventional binders that require burning or toxic solvents to remove, GRST's material can be washed off simply with water, as he showed in a live demonstration on stage. This is a game-changer in reducing harmful PFAS ''Forever Chemicals' and enabling safer, scalable battery recycling.
"True innovation doesn't just change technology, it changes lives. Cleaner batteries, a cleaner planet, smarter recycling, and a future we can all believe in."
— Mr. Frank Harley, GRST
MAYANI Co-Founder and CEO, Mr. JT Solis, highlighted his team’s mission to climate-proof and strengthen the livelihoods of smallholder farmers and fisherfolk in the Philippines, by improving access to markets, credit, and climate-smart agricultural inputs.
"We have an obligation to try. We have an obligation to aspire. We have an obligation to take action, especially on behalf of the so many who still have so little."
— Mr. JT Solis, MAYANI
MYCL uses mushroom mycelium, the root-like structure of fungi, to create alternatives to leather. This approach upcycles agricultural waste while producing sustainable bio-based materials that are flexible, durable, and comparable to animal-based products.
Mr. Arekha Bentangan, Co-Founder and Chief Innovation Officer, said MYCL partners with local villages across Asia, teaching communities how to participate in the production process and helping them generate income through collaboration.
"MYCL creates strong layers of mycelium that are comparable to conventional leather. We can solve two problems at the same time: reducing agricultural waste and producing valuable and sustainable leather-like materials. It's not leather — it's better!"
— Mr. Arekha Bentangan, MYCL
Sampangan’s proprietary carbonisation technology converts underutilised agricultural waste, such as coconut shells, candlenut shells, and hardwood, into industrial-grade products such as activated carbon, biochar, liquid carbon or biofertiliser, and wood vinegar. These outputs have a wide range of industrial use cases.
This approach helps reduce waste while lowering industrial emissions and improving energy efficiency.
"Our mission as a company is to redefine the creation of prosperity to prove that sustainability can be profitable and profitability should be sustainable."
— Ms. Hana Purnawarman, Sampangan
Throughout the Summit, the mentees also anchored a dedicated Amplifier booth at the Innovation Showcase segment, actively engaging PAS delegates in conversations about their solutions and potential collaborations, and showcasing product samples.
Closing Reflections
The week drew to a close with a reflective, interactive session diving into the founders’ personal backgrounds, core motivations, progress they have made, and aspirations.
Through structured exercises, they surfaced the deeper drivers behind their work — ranging from early influences and lived experiences to the values that keep them grounded in the face of uncertainty. They unpacked the emotional drivers beyond professional missions, revealing motivations rooted in empathy, creativity, and a desire to solve real-world problems for their communities.
The mentees also shared their biggest wins in the past year, including business clarity, successful product launches, and moral reaffirmation.
Looking ahead, they laid out concrete, 12-month goals alongside long-term aspirations, ranging from business growth to personal ambitions like authoring a book and bridging divides between communities.
