The rise of Tough Tech.

Across the globe, teams of scientists, engineers, and entrepreneurs are developing technologies to mitigate climate change, enrich human health, and create the next generation of bedrock systems and infrastructure. Just a decade ago, however, such teams struggled to find venture investors willing to support the necessary technology development before their solutions reached commercial viability. But something’s changed.

As we showcase in this report, venture investment in Tough Tech has never been stronger — and that’s good news for everybody.

Q&A

  • What is the Engine?

    The Engine is an early-stage venture firm that invests in Tough Tech companies commercializing transformative technology that will lead to a healthier population, more accessible and adaptive society, and a more resilient world.

    It was conceived of and created by MIT to address the need for sustained support for startups commercializing breakthrough science and engineering, with the potential to solve intransigent global problems and make a material, positive impact on society. Launched out of MIT in 2016, The Engine was designed as an “innovation orchard,” where Tough Tech founders could have access to capital, infrastructure, and a growing network of stakeholders needed for them to be successful. Together, these three elements combine to create a model around which we can build an innovation ecosystem that successfully translates breakthrough research to impact.

  • What is Tough Tech?

    Tough Tech is transformative technology that solves the world’s most difficult challenges through the convergence of breakthrough science, engineering, and leadership. While it is often grouped with Deep Tech or Frontier Tech, Tough Tech differentiates itself by always centering on mission and purpose.

    Tough Tech has the potential for big returns and global impact, through the creation of new foundational economic infrastructure and by enabling the transformation of existing industrial activities. The Engine’s Tough Tech founders have proven breakthrough science in labs and are taking the next step to bring their technologies to market and impact. These companies will improve human health and agriculture, build resilient systems, enable adaptive infrastructure, and adapt to — and even reverse — climate change.

  • How has your investment thesis around Tough Tech evolved given the past few years’ developments in the space?

    Our commitment to early-stage investment in Tough Tech companies has remained unchanged. Previously, skeptics of investment in Tough Tech would point to long technology development timelines and capital intensity as barriers to successful returns. However, the pandemic, coupled with the scientific and technological world’s response, has highlighted the importance of supporting Tough Tech across not just health, but also other urgent societal challenges, such as climate change. The Engine continues to identify, fund, and offer the infrastructure needed to startups pursuing transformational changes.

    Although our investments are broadly defined as Tough Tech, each industry in which Tough Tech can play a role has unique trends and economics that factor into the investment thesis in that space. We invest across three segments: Climate Change, Human Health, and Advanced Systems & Infrastructure.

    However, a few key underlying themes exist that carry across every industry. First and foremost is finding incredible founders to build diverse and people-oriented companies — great technical founders who can traverse the difficult journey of Tough Tech and attract great people — is key to long-term success. Other essential factors are technologies that can potentially impact society on a global scale and transform industry. To take big swings and conquer Tough Tech, we dream big and understand the hurdles impeding progress in each industry.

  • How is Tough Tech investment different from other early-stage technology investing?

    The Engine’s approach focuses on shepherding work from the lab and academia to commercial reality. Discovery is just the start. Bringing new science and technology to market requires a unique skillset and an entrepreneurial drive. We’ve designed programming, such as our Blueprint Program, to foster these skills and promote the next generation of Tough Tech entrepreneurs.

    While commercializing Tough Tech, a founder has to manage risk across four dimensions: technical, market, scale, and regulatory. Assessing those risks requires expertise in the specific technical fields, an understanding of intricate market structures, and engagement with the policy community — a combination of knowledge that is difficult to assemble in the time period normally allotted for company diligence. At The Engine, we have worked to build a network of technologists, investors, government representatives, corporates, and academics that provides important feedback during our diligence process, and we work closely with our portfolio companies as they move forward.

  • With increased scrutiny on venture capital diversity, what are some of the ways The Engine is addressing diversity and inclusion within the firm, as well as with investments?

    Diversity has been central to The Engine’s values from the beginning, and we are particularly proud of the makeup of our founders to date. In the past 18 months, we have seen the conversation around venture diversity change. This open dialogue means looking more closely at the representation of our portfolio, as well as our firm, and identifying how we can continue to do better. Today, 66.6% of companies have a minority CEO and/or founder (defined as Asian/Asian American, Black/African American, Latinx, American Indian, Native Pacific Islander, and/or women); 44% of our companies have a female founder; and 66.6% have a female executive or board member. While we are incredibly proud of our progress thus far, we all have more work to do.

  • How has the increased pace and volume of early-stage investment impacted The Engine’s investment strategy?

    Like the rest of the venture capital industry, the last year has been an exciting time at The Engine. We announced the close of our second fund in fall 2020, and have invested in 9 new companies—spanning dynamic and accessible routing for public transit (The Routing Company), to distributed chemical production (Emvolon), to cement decarbonization (Sublime Systems). Since its inception, The Engine has invested in 36 companies across both of our funds.

  • What do you look for in a founding team?

    We look for founders with the drive and passion to fulfill their mission. They must be working on groundbreaking science or technology that has the potential to solve a big global problem and the opportunity to transform an industry.
