Top Tier Impact

What Top Tier Impact does

Top Tier Impact (TTI), founded in 2019 in London by Alessa Berg, is a privately held, for-profit impact investing ecosystem operating three interconnected businesses: TTI Network, a curated global private community of roughly 600 active members and 25,000 registered subscribers spanning 80+ countries; TTI Investing, an investment advisory placing debt and equity into growth-stage companies across green infrastructure, nature-based solutions, agriculture, energy systems, and fintech; and TTI Advisory, a corporate innovation consultancy that delivers programs such as Ecosystem Innovation Strategy, Reverse Demo Days, and Strategic Innovation Sparks to enterprise clients. The platform is technically a community and convening layer, comprising a private member portal, global WhatsApp groups, an ambassador-led chapter network in 30+ cities, and a flagship events program anchored at Davos/WEF, COP, Climate Week NYC, and Web Summit, rather than a software product.

TTI monetizes through a tiered subscription membership (basic tier publicly priced at $40/month billed annually), enterprise advisory engagements (quote-based, with named clients such as SAP), and capital mobilization mandates for post-traction funds and ventures. Supporting sub-brands include TTI Events, TTI Capital Mobilization, TTI Policy, TTI Ambassadors, and the TTI Global Impact Awards (established 2021). Member-reported outcomes include Wave Mobile Money securing €90 million in debt financing facilitated by TTI and Tomorrow University closing a $10 million Series A through the network, with cumulative facilitated investments cited at $800+ million across debt, equity, and blended structures. TTI is bootstrap-style and founder-led, with no disclosed institutional funding rounds, parent company, or public revenue figures.
