KdT Ventures
KdT Ventures, co-founded by Cain McClary and Mack Kolarich, is an Austin-based VC firm backing frontier-science startups rewiring the physical world.
KdT Ventures
KdT Ventures was co-founded in 2015 by Cain McClary and Mack Kolarich, who left white-shoe law and finance careers to build a venture franchise purpose-built for frontier science. Rather than emerging from a traditional tech or life-sciences silo, the firm was constructed around a thesis that software-enabled tools — AI, robotics, cloud computing — would not just disrupt enterprise IT but would reengineer how atoms, molecules, and cells are manipulated at industrial scale. This has placed KdT at the center of a funding arc often labeled 'deep tech' but more precisely defined by the firm as the digitization of the physical world. The firm targets pre-seed and seed-stage companies clustered at the intersection of computation and chemistry, biology, and advanced manufacturing. KdT has backed startups building programmable biology platforms for drug discovery and specialty chemical synthesis, AI-driven materials design tools, and industrial robotics systems for laboratory automation. Confirmed portfolio companies include Solugen, which uses enzymatic pathways to produce carbon-negative chemicals (per Pitchbook-disclosed round data, 2017–2021), and Asimov, a synthetic biology CAD platform that programs living cells for therapeutic and industrial applications. The portfolio also historically included Zymergen, a molecular manufacturing pioneer that KdT backed early, which later went public via SPAC in 2021. KdT invests primarily across North America, with a concentration in biotech hubs like Boston, the Bay Area, and emerging innovation clusters in the Southeast. KdT raised its first institutional fund in 2017 and has since scaled to multiple vintages, though the firm does not publicly disclose total AUM or fund sizes. The firm operates from a single headquarters in Austin, Texas, anchoring itself in a city that has become a gravitational center for deep-tech talent and non-traditional venture capital. KdT distinguishes its platform with an in-house science team — rare for a seed-stage firm — that provides portfolio companies with wet-lab and computational modeling support, acting not merely as a capital source but as a technical co-builder. The firm maintains a network of corporate partners and academic collaborators that feed its sourcing pipeline, which relies heavily on relationships inside university spinout ecosystems and government research institutions. KdT's structural differentiator is its positioning as a pure-play frontier-science firm operating at the earliest stages, a space historically underserved by venture firms who lack the scientific fluency to diligence and support companies building in atom-level domains. Unlike multi-stage firms that treat science investing as a satellite strategy, KdT has no diversified software or consumer portfolio — the entire partnership is organized around evaluating scientific risk. This gives KdT a narrow but defensible lane in a venture market where most seed-stage capital flows to SaaS. As the policy tailwinds from the CHIPS Act and growing biomanufacturing national-security concerns accelerate capital into bioeconomy infrastructure, KdT enters its second decade with a portfolio architecture few early-stage firms can replicate.

Frequently asked questions
Who makes investment decisions at KdT Ventures?
Co-founders and Managing Partners Cain McClary and Mack Kolarich lead the investment committee. KdT operates with a flat partnership structure typical of early-stage funds, where all general partners participate in final investment decisions. The scientific team — a distinguishing operational feature — conducts technical diligence and often advises on deal viability, but final check-writing authority rests with McClary and Kolarich.
What does KdT look for in a company before leading a seed round?
KdT seeks teams with deep scientific expertise — often PhD-level founders emerging from academic labs — who are applying computational tools to biology, chemistry, or materials science problems. The firm prioritizes theses where software or AI meaningfully speeds up an industrial or therapeutic development cycle, not where it provides a marginal efficiency gain. KdT's scientific team evaluates the technical moat before a term sheet is ever drafted.
Does KdT lead rounds or predominantly co-invest?
KdT actively leads pre-seed and seed rounds — a posture the firm established early to secure meaningful ownership in science-heavy startups where syndicate formation can be challenging. The firm will occasionally co-invest alongside other deep-tech specialists like Breakthrough Energy Ventures or Lux Capital, particularly in later rounds where capital requirements exceed its fund mandate.
How does KdT source proprietary deal flow?
KdT's sourcing model leans heavily on relationships within the academic spinout ecosystem — principal investigators, technology transfer offices at research universities, and venture-creation groups inside national labs. The firm's in-house science team also attends specialized technical conferences and reviews pre-print servers, giving it visibility into breakthroughs before they become broadly marketed funding opportunities. This contrasts with network-driven consumer-tech origination.
Is KdT investing out of a single fund, and what is its current dry powder?
KdT closed its third fund in June 2023 at $160 million (per TechCrunch, June 2023). The firm does not publicly disclose remaining dry powder. While Fund III is the active primary vehicle, KdT may also reserve capacity in prior funds for follow-on investments in breakout portfolio companies.
Which sectors does KdT explicitly avoid?
KdT does not invest in enterprise SaaS, consumer internet, or traditional financial technology — sectors that constitute the bulk of early-stage venture deal flow. The firm also avoids therapeutics companies that are pursuing pure clinical-play strategies without a platform-technology underpinning. In practice, KdT will pass on any company whose core value proposition is not grounded in a scientific or engineering breakthrough in the physical world.
How does KdT support portfolio companies beyond capital?
KdT maintains an in-house science team — an unusual resource for a firm its size — that assists portfolio companies with wet-lab experimental design, computational modeling, and navigating complex intellectual property landscapes. The firm also brokers introductions to downstream growth-equity investors and corporate partners, including industrial incumbents who may become development collaborators or acquirers.
