The revealing request came from the CFO. TDK Ventures had been recording its work with startups in detailed reports: introductions, evaluations, pilots, design-ins, revenue. There was plenty to read. What was harder to see was whether all that activity was going anywhere. The CFO wanted something simpler: “Give me one slide that shows everything.”
Out of that request came a checkerboard. It tracks how relationships between portfolio companies and the wider TDK organization develop over time. A change of color makes progress visible. For an investor selling access to a large corporation, this is an unusually useful question: what actually happened after the introduction?
- Early-stage capital for technologies that have to work in the physical world.
- Manufacturing, pilot and customer support drawn from TDK’s industrial network.
- Public scorecards and collaboration trackers that founders can borrow.
The factory is part of the offer
TDK Ventures is the corporate venture capital arm of TDK Corporation, the Japanese electronics and materials company. It invests in young technology businesses, typically from Seed through Series B. Its territory includes batteries, robotics, semiconductors, advanced materials and energy systems: businesses whose progress must eventually survive contact with a physical production process.
The firm calls its additional support “TDK Goodness.” The name is cheerful. The work is specific: product validation, pilot programs, manufacturing advice, supply-chain connections and introductions to potential customers. Its Engagement Team connects startups with the parent company’s ecosystem; its Scaling Team helps with operating needs such as hiring, capital planning and reaching buyers.
The interesting discipline is who gets to decide whether this help counts. In its February 2026 account of its first 50 investments, TDK Ventures says founders must confirm that the support was valuable. An investor’s busy calendar does not automatically become a startup’s achievement.
Start with $50 million. Earn the next fund.
Founder and president Nicolas Sauvage arrived inside TDK through its acquisition of InvenSense. At a Stanford executive program, a lesson about exploration and exploitation gave him a way to explain corporate venture investing: a company could investigate unfamiliar markets through small investments before committing to much larger moves. He pitched the idea despite being a newcomer outside the Tokyo headquarters.
TDK announced the venture subsidiary in July 2019 with an initial $50 million fund. The mandate centered on materials science, energy and related technologies that conventional venture portfolios often overlooked. By the announcement of its second fund in 2021, the firm could point to three early exits: GenCell’s public listing, SLD Laser’s acquisition by Kyocera and Origin’s acquisition by Stratasys.
The second fund brought another $150 million. Fund EX1 added $150 million in 2023, concentrating on electrification and decarbonization in the United States and Europe. TDK’s battery subsidiary ATL joined as a limited partner. In April 2025, Fund 3 added $150 million, bringing reported assets under management to $500 million.
A battery process meets a battery maker
What does the corporate connection buy? Consider AM Batteries, a portfolio company developing dry electrode manufacturing. In March 2025 it announced a joint development agreement with TDK Corporation to work on more efficient battery production and next-generation storage. There is a concrete relationship behind the promise of introductions: a startup with a manufacturing technique and an established manufacturer agreeing to develop it together.
Glimpse offers another view of the same industrial problem. Its X-ray computed tomography software assesses battery manufacturing quality. TDK Ventures led its $10 million Series A, announced in March 2025. That figure is the entire financing round, rather than a disclosed TDK check. The practical ambition was to increase scanning throughput and reach new customers.
These are portfolio companies’ products. TDK Ventures itself sells no inspection robot or battery scanner. Its business is investing for financial returns while helping its corporate backers learn about technologies and markets. Founders receive capital and potential operating support; TDK gains exposure to businesses that could become future partners, suppliers or customers.
The spreadsheet leaves room for doubt
The firm’s public investment scorecard makes that bargain easier to examine. Its seven pillars cover strategic value, market potential, team, co-investors, technical advantage, competitive advantage and execution risk. The framework asks whether a company can become valuable enough to return capital at the scale of a fund, alongside strategic usefulness and positive societal impact.
Here is the amusing admission: the investment committee has approved a company whose scorecard contained only red and yellow ratings. No green. Its early stage and risk-adjusted valuation mattered. The scorecard organized the uncertainty; it did not eliminate judgment.
Toyota Ventures and Schneider Electric-backed SE Ventures offer overlapping alternatives in climate and industrial technology. Corporate access alone therefore does not distinguish TDK Ventures. The more persuasive difference is the fit between a particular startup’s bottleneck and TDK’s materials, sensors, power electronics and manufacturing expertise. A founder should be able to name the help needed.
No green ratings.

Borrow the checkerboard
The reporting problem has a useful lesson beyond venture capital. Detailed accounts of activity proved insufficient for the CFO’s request. The team changed how it presented progress, making the stages of collaboration visible on one slide. In February 2026, it shared the checkerboard publicly under a Creative Commons license, following the release of its investment scorecard.
For a founder, the copyable move is to define the next observable step: an evaluation, a pilot, a design-in, eventually revenue. Ask who owns it. Review what changed. A list of impressive contacts becomes more useful when each relationship has a job to do.
Fit still matters. TDK Ventures’ submission page excludes areas including fintech, edtech, food and life science. Even within its scope, a pilot requires a willing counterpart and a workable product. Access cannot promise either. The fund sizes are commitments to invest, not evidence that every factory problem has been solved.
Its recent announcements keep that distinction alive. In May and June 2026, TDK Ventures backed C2i Semiconductors and Aston Power around AI infrastructure’s power needs. September brought R3 Lithium, its 55th portfolio company, focused on recovering lithium carbonate from recycled battery materials. Continuous commercial production is a 2027 target. The checkerboard still has colors left to change.
