The Flinch We Forgot

A letter to America at two hundred and fifty… and the two fears hiding inside every investment we make.

OUR LIMITED PARTNERS

SEE THEM FIRST. WITH US.

TENSEUR is for investors who will stay the whole way: from a tested technology, through deployment at scale, to a high-growth company that lasts.

We invest, from a pooled fund, on behalf of:

Industrial corporates without a venture arm: a Silicon Valley manager investing in frontier industrial technologies, and an early view of the companies most likely to enter your value chain as suppliers, partners, or acquisition candidates.
Foundations, endowments, and sovereign wealth funds: patient capital matched to industrial time, with grants and other non-dilutive capital alongside equity when they help a company reach its next milestone.
Funds of funds and GP seeding programs: a focused first fund with a defined Technology Readiness Level 5 entry gate, led by a GP who underwrites like a lender.
Family offices and qualified individual investors: access to seed-stage critical industrial technology through a pooled fund.

You are early because the company is not obvious yet. You are not early because the idea is untested. Whether you are allocating to private markets or considering an anchor commitment to a first-time fund, we will be as direct and as careful as we would want someone to be with us.

TENSEUR Fund I at a Glance

Fund Overview

Investment Stage: Seed-stage industrial deep technology startups with TRL 5+ prototypes.
Geographical Focus: Primarily U.S.-based.
Investment Exclusions: TENSEUR does not invest in software businesses, including SaaS, computational biology platforms, and computational materials platforms, whose primary asset is code sold to discover, operate, monitor, or optimize systems they do not own or make. TENSEUR also does not invest in consumer products or consumer hardware, fintech, crypto, gambling, video games, cannabis, or tobacco. It does not invest in companies whose primary product is a weapon designed to cause lethal harm. Dual-use companies, whose frontier technologies serve commercial markets and mission-driven organizations alike, are within scope.
A therapeutics company may run quantum simulations to design the molecules it develops. A semiconductor company, fabless or integrated, may write its own firmware. A quantum company may write control software for machines it builds. These are not software companies. The exclusion applies to businesses whose only value is the software layer itself.

Investor and Deployment Profile

Investor Archetypes: Industrial corporates, foundations, endowments, sovereign wealth funds, funds of funds and GP seeding programs, family offices, and qualified individual investors.

Investment Parameters and Logistics

Commitments Currently Discussed: $50,000 to $5,000,000 (median allocation: $300,000).
Ways to Invest: Cash, trusts, entities, IRAs, 401(k), or non-U.S. structures.
Compliance: Prospective limited partners should expect third-party verification of accredited investor status, KYC and AML review, and CFIUS-related screening before any interest is issued. The third-party fund administrator would likely repeat those screens annually. A subscription is not complete until those initial screens are completed and the Governing Documents fully executed.

Risk and Disclosures

Liquidity & Capital Loss: Investors may lose all or a substantial amount of their investment in the Fund as a result of identified and/or unidentified risks.
Suitability: An investment in the Fund is not suitable for non-accredited investors.

For illustrative purposes only. Final terms and conditions are strictly subject to definitive subscription documents.
