MaRS Investment Accelerator Fund (IAF) is one of Canada’s most active early-stage venture funds, focused on seeding and scaling high-potential technology startups in Ontario. Its mission is to keep Ontario’s top talent and breakthrough technologies rooted in the province while equipping them to compete and scale globally. As a seed-stage investor, IAF typically writes first cheques of around $500,000 into startups with limited revenue, backing founders at the earliest stages of product-market fit and commercialization.
IAF invests across three core sectors: enterprise software, healthtech, and cleantech, with a growing emphasis on deep tech, including AI, semiconductors, photonics, advanced materials, and aerospace. The fund plays a critical role in Ontario’s innovation ecosystem by de-risking early ventures, validating business models, and catalyzing follow-on capital. With a strong track record—often cited as performing in the top quartile of North American VC funds—IAF has deployed tens of millions of dollars into over 200 companies, helping them raise significant follow-on funding and achieve multiple exits.

MaRS Investment Accelerator Fund was launched in 2005 as part of MaRS Discovery District, a non-profit innovation hub based in Toronto. Born out of Ontario’s broader strategy to strengthen its knowledge economy, IAF was designed to bridge the early-stage funding gap for technology startups emerging from research institutions, accelerators, and entrepreneurial hubs across the province. Funded by the Government of Ontario and delivered through the Ontario Network of Entrepreneurs, IAF was structured to be more than just a capital provider—it was built to be an ecosystem enabler.
Over time, IAF evolved from a government-backed seed program into a professionalized, evergreen venture fund with a dedicated investment team. A pivotal moment came with the spinout of Graphite Ventures, MaRS’ later-stage fund, which allowed IAF to sharpen its focus on pre-seed and seed investments while creating a clear capital pathway for MaRS-affiliated startups. This strategic separation reinforced IAF’s identity as a hands-on, founder-first early-stage investor deeply embedded in Ontario’s tech fabric.

Unlike traditional VC funds with fixed life cycles, IAF operates as an evergreen fund, enabling it to maintain a steady pace of investments and long-term support for founders from day zero through seed and into growth stages.
IAF leverages MaRS’ vast innovation ecosystem—spanning capital, research, corporate partners, legal, IP, and government—to provide portfolio companies with more than just money. Startups gain access to mentorship, commercialization support, customer introductions, and talent networks that are typically available only at much larger funds.
While many seed funds concentrate on SaaS and consumer apps, IAF has carved out a niche in capital- and R&D-intensive sectors like cleantech, healthtech, AI, semiconductors, and advanced materials. This allows it to back ambitious, science- and engineering-driven founders who are building foundational technologies.
IAF consistently ranks among the most active early-stage investors in Canada. Its portfolio companies have gone on to raise substantial follow-on capital and achieve meaningful exits, demonstrating its ability to identify and de-risk promising ventures. The fund’s strong performance—reportedly averaging over 20% returns historically—has cemented its reputation as a top-tier seed investor.
The IAF team combines investing expertise with real-world operating experience, allowing them to speak the language of founders and provide practical, hands-on guidance. They position themselves as long-term partners, not just check-writers, helping founders navigate product, go-to-market, and fundraising challenges.

MaRS IAF sits at the heart of a critical trend: the rise of deep tech and hard tech innovation in Canada, particularly in Ontario. As global demand grows for AI, climate tech, advanced manufacturing, and next-generation health solutions, IAF is uniquely positioned to back the foundational technologies that will power these shifts. Its focus on sectors with long development cycles aligns with a broader shift in venture capital toward patient, mission-driven investing in science and engineering breakthroughs.
Timing is on IAF’s side. With increasing government and institutional interest in building domestic tech sovereignty—especially in semiconductors, clean energy, and life sciences—early-stage funds that can de-risk and scale deep tech startups are more valuable than ever. IAF’s integration with MaRS’ innovation infrastructure gives it a structural advantage: it can identify promising research from universities and hospitals, connect founders with pilot customers, and help them navigate regulatory and commercialization hurdles.
Beyond capital, IAF shapes the ecosystem by setting a high bar for founder support, encouraging collaboration across sectors, and proving that Ontario can produce globally competitive technology companies. Its success helps attract more talent, capital, and corporate interest to the region, reinforcing a virtuous cycle of innovation and growth.

MaRS IAF is poised to deepen its role as a cornerstone of Canada’s early-stage innovation infrastructure. As it continues to back more deep tech and hard tech ventures, it may expand into dedicated vertical programs—such as a formal biotech or climate tech strategy—potentially in partnership with specialized players like AdMare. The fund is also well-positioned to act as a bridge between public research, private capital, and global markets, especially as governments double down on strategic technology sectors.
Looking ahead, IAF’s biggest opportunity lies in scaling its impact beyond Ontario. While its mandate is firmly rooted in the province, its portfolio companies are increasingly global from day one. By strengthening cross-border LP relationships and co-investment networks, IAF can amplify its influence while staying true to its mission of keeping Ontario’s best ideas and talent at home.
In a world where breakthrough innovation is increasingly capital- and expertise-intensive, MaRS IAF exemplifies what a modern, ecosystem-native seed fund can be: a patient, strategic, and deeply connected partner that doesn’t just fund startups, but helps build the next generation of Canadian tech champions.
