Climate Technology

Union Square Ventures (USV)

Check: No personal check-size range is published. USV describes itself as an earliest-stage generalist investor and makes decisions collaboratively without a vote; round fit should be confirmed with the partnership rather than attributed to Andy alone.

Andy invests at the edge of large markets under transformative pressure. His long-running thesis work centers on engaged networks, differentiated user experience, and defensibility created by network effects, then expands to enabling infrastructure, market-specific networks, and open decentralized data. More recent writing examines patient-centered healthcare and trust, openness, and native behavior in AI.

Maki.vc (Web3)

Check: Maki targets first rounds below EUR 5 million and supports consequent rounds; this is a firm round criterion, not Pirkka's personal check range. Active new investments come from Fund III.

Pirkka backs ambitious Nordic teams at their first rounds, combining an operator's technology and scaling perspective with Maki's sector-agnostic, non-consensus approach. His attributed investments favor experienced teams rebuilding large industries with scalable platforms—payments, sustainable construction materials, physical-world digital twins, enterprise systems, and other deep or brand-driven technologies.

Khosla Ventures

Check: No Jessy-specific check size is disclosed by Khosla Ventures. Publicly observed work spans an $11 million Spiritus seed financing led by Khosla and Pascal's $8 million seed round, but round size is not the same as the firm's check. Third-party claims of a $100,000–$5 million range were excluded as unverified.

Jessy looks for climate technologies grounded in hard science and non-obvious mechanisms that can make a meaningful dent in greenhouse-gas emissions. Her career shows a materials-to-systems lens: understand the physical mechanism, identify the governing cost and performance variables, build around available supply chains, and prove a path from laboratory result to commercially relevant hardware. Spiritus reflects this in lower-energy, lower-cost direct air capture; Pascal in solid refrigerants operating below 10 bar with off-the-shelf components. She is comfortable with capital-intensive physical products when a technical discontinuity creates a credible route to scale and economics.

General Catalyst

Check: No personal check-size range is published. Her public record spans seed investments through large follow-on rounds, but total financing sizes and General Catalyst's assets are not personal check parameters.

Jeannette is a founder-led generalist investing to strengthen European prosperity and resilience through technology. She backs ambitious companies from ideation onward across AI, defense, energy, industrial transformation, enterprise, and consumer markets, connecting startups with established industry. Her Global Resilience lens focuses on owning critical systems of power, scaling European technical talent, and commercializing technologies until they can thrive without permanent subsidy.

Union Square Ventures (USV)

Check: USV publishes a firm-wide check range of $1 million to $30 million and invests from the earliest stages through follow-ons. It does not publish Rebecca's individual authority, and the partnership makes decisions collectively without a vote.

Rebecca invests at the edge of large markets, with a consumer and product lens sharpened by USV's network-effects thesis. Her current view links abundant AI intelligence, cheaper hardware, sensors, and edge processing: newly reachable data from bodies, infrastructure, environments, and machines can power self-improving products and physical systems. She also expects open agent infrastructure to enable a wave of useful, creative, networked consumer applications outside dominant model platforms.

Maki.vc (Web3)

Check: Maki's stated sweet spot is first rounds below EUR 5 million from day zero; this describes target round size, not Pauliina's personal check authority. The firm continues to support later rounds selectively.

Pauliina leads a sector-agnostic Nordic first-round strategy centered on exceptional technical founders with global ambition. Her attributed portfolio work spans clinical sensing, autonomous-mobility safety, consumer products, voice agents, quantum, fintech, and sustainability. She favors non-consensus decisions, products rooted in a clear user problem, strong design and customer experience, and teams capable of building category leaders from the Nordics.

AirTree Ventures (Web3)

Check: Neither Airtree nor Elicia publishes her personal check range or decision authority. Airtree describes itself as seed-first and able to support companies through their journey; a historic Fund III article mentioned a $200k seed entry point, but that is firm- and vintage-specific rather than a current personal range.

Elicia backs highly ambitious, resilient founders from Australia and New Zealand, often beginning at pre-seed or seed and supporting them across later rounds. Her disclosed portfolio spans AI-enabled enterprise software, workforce intelligence, healthcare, agricultural and climate technology, and B2B SaaS. Her writing emphasizes technology's capacity for positive impact, founder ambition, durable relationships, product love, domain depth, and accepting concentrated venture risk in pursuit of outlier outcomes.

Khosla Ventures

Check: In a 2020 first-person interview, Samir described a typical Khosla Seed Fund investment as roughly $1M–$2M, used as option-value capital to remove key risks before a larger Series A/B decision. Khosla's current Main Fund covers early through later stages, including total financings above $10M. These are historical/firm-level guideposts, not a guaranteed current personal range.

Samir prefers large, known markets where a radical technical risk can produce a 10x-better product. He treats small seed checks as option-value experiments: identify a potential billion-dollar outcome, use capital to remove a binary technical, team, or market-development risk, then redo the diligence and concentrate capital if the evidence improves. He rejects mechanical pro-rata, values non-consensus decisions, and believes uncapped upside justifies bold technical bets rather than conservative hit-rate optimization.

Khosla Ventures

Check: No personal check-size range is published. Khosla invests from seed through growth; company round totals and the firm's assets are not Sven's personal check parameters.

Sven backs technically ambitious companies that can create new industries or unlock novel user experiences. His engineering lens favors frontier AI, robotics, autonomy, aerospace, developer infrastructure, climate, and other atoms-plus-software businesses where improved simulation, computation, manufacturing, or foundational models make a previously government-scale or uneconomic problem tractable for a startup.

Maki.vc (Web3)

Check: Maki's sweet spot is first rounds below EUR 5 million; this describes the firm's target round, not Wilson's personal authority. He sources and evaluates opportunities within that day-zero mandate.

Wilson sources and evaluates Nordic first-round opportunities across Maki's sector-agnostic mandate, with a research-driven lens and responsibility for ESG development. His first publicly attributed 2026 investment highlights critical deep-tech infrastructure: technically defensible systems addressing a rapidly worsening physical-world problem, with government and commercial customers and a concrete path from development into operational proof.

Maki.vc (Web3)

Check: Maki's published sweet spot is first rounds below EUR 5 million from day zero; this is a firm round-size criterion, not Paavo's personal check range. Fund III is the active new-investment vehicle, with selective follow-ons from older funds.

Paavo backs Nordic deep-tech founders at their first institutional round when a radical scientific or engineering advance can overhaul an industry. He requires a credible technical foundation, balanced technical and commercial talent, control of a valuable position in the value chain, deep customer understanding, and a distinctive brand capable of making complex technology category-defining.

Norrsken VC

Check: Norrsken VC currently states €1M–€10M early-stage and growth tickets. This is the firm's range, not Tove's personal promise. Confirm initial ticket, follow-on reserves, ownership and stage with the team.

Tove backs ambitious European technology companies whose commercial growth directly improves outcomes for people or planet. Her Bain private-equity background and early impact roles add rigorous market and diligence discipline. Current health-AI work highlights companies that combine deep sector expertise, proprietary data and measurable time or cost improvements in critical systems such as clinical trials.

Union Square Ventures (USV)

Check: USV states that the firm writes $1 million to $30 million checks and invests from the earliest stages through the full company journey. This is a firm-wide range, not Albert's personal check authority; decisions are discussed collectively without a formal vote.

Albert is a thesis-driven generalist investing at the edge of large markets under technological and societal pressure. His current work emphasizes AI-enabled scientific discovery, robotics that can operate reliably in complex physical environments, resilient energy and civil infrastructure, and products that expand human agency. Across these areas he looks for compounding data or participation loops and systems that turn rapidly improving technical capabilities into durable real-world utility.

First Round Capital

Check: First Round's published firm-wide initial checks are typically $1M–$7M, averaging about $3.5M; it has participated in rounds from $100K to $20M. No personal range is published for Hayley.

Hayley backs very early founders tackling real-world systems—especially healthcare, climate, supply chain, and commerce—that have been overlooked or written off as unsolvable. As a former founder, she evaluates both halves of the journey: the cold mechanics of execution and the emotional endurance of company-building, combining data-driven precision with direct, empathetic support.

Northzone (Web3)

Check: No personal check-size range is published. Jessica invests through Northzone's multi-stage funds; financing announcements report total rounds, not her personal allocation range.

Jessica backs product-led platforms and UX-driven software that use technology and intuitive experiences to disrupt traditional industries. Her operator lens emphasizes speed and momentum at company formation, then patient, conviction-based founder relationships. She is especially interested in growth loops embedded in product—onboarding, usage, community, and data—rather than growth purchased only through advertising.

Norrsken VC

Check: Norrsken VC currently publishes €1M–€10M early-stage and growth tickets. This is a firm range rather than Anna's personal authority. Confirm geography, initial ticket, ownership, reserves and impact qualification through the firm's pitch process.

Anna combines Norrsken's impact-return mandate with eight years of strategy, operations and international market expansion at Spotify. Her likely value is testing whether an early impact company can turn a strong product into repeatable multi-market growth without losing operational discipline or the causal link between usage and measurable impact.

Northzone (Web3)

Check: No personal check-size range is published. Pascual invests at early stage through Northzone; founders should confirm current round fit directly and should not infer his allocation from portfolio-company financing totals.

Pascual focuses on early-stage AI, fintech, healthcare, and vertical SaaS, with particular interest in products that use growing data availability and improved computation to transform an industry. His portfolio spans AI for legal work, medical analysis, debt collection, sales, payments, and mental healthcare, indicating an applied, industry-specific orientation.

Ecliptic Capital

Check: The firm does not publish a person-specific check-size range on its current official website.

Greg Strake is part of Ecliptic Capital's current team. No narrower person-specific mandate is published, so this profile uses the firm's official strategy: Invest patient capital in transformative technologies at pivotal early stages and help technical innovators turn defensible ideas into enduring businesses.

Khosla Ventures

Check: No personal check range is published. Khosla's Seed Fund finances science and business-model experiments, while its Main Fund invests from early to later stages; historical firm commentary described many seed investments around $1M–$2M. These are firm-level guideposts, not Alice's authority.

Alice invests in deep technology and sustainability, informed by mechanical engineering, consumer hardware, and her experience taking a physical product from idea to thousands of retail locations. She is positioned to evaluate whether a scientific or engineering advance creates a meaningful economic advantage, can be manufactured and distributed, and has a low-cost path through its critical technical and market risks.

Khosla Ventures

Check: No personal check range is published. Khosla finances early technical experiments through its Seed Fund and larger early-to-late opportunities through its Main Fund; historical firm commentary described many seed investments around $1M–$2M. These figures are not Rajesh's personal authority.

Rajesh backs bold founders reinventing how the world powers, builds, and heals itself. His two decades in corporate venture, startups, and network systems inform an industrial-scale lens across renewables, decarbonization, advanced manufacturing, critical minerals, compute infrastructure, and the convergence of those fields with AI. The core question is whether a technical advance can survive scale-up and reshape the economics of a foundational system.

AirTree Ventures (Web3)

Check: Neither Airtree nor Kell publishes his personal check range or decision authority. The firm describes itself as seed-first and able to support companies over time; portfolio round sizes and prior-firm deals are not treated as evidence of his current range.

Kell applies a long-horizon Silicon Valley investing perspective to Airtree's Australia and New Zealand mandate. His concise screen asks what drives demand, what makes the company different, and whether he is excited to work with the team. He looks for founders who combine the passion to become the best, humility to keep learning, and the courage to remain stubbornly optimistic.
