## History and people
Matthew Rhodes-Kropf is the founding managing partner. He is a professor in the finance department at MIT Sloan, where he teaches entrepreneurial finance with a focus on artificial intelligence and leads an incubator that launches companies with Harvard and MIT students.[2](https://www.tectonicventures.com/) His recent collaborations include MIT spin-outs OmniML (acquired by NVIDIA), Voyage AI (acquired by MongoDB), Butlr, and Eigen AI (acquired by Nebius).[2](https://www.tectonicventures.com/)
Morris Miller, a managing partner on Fund II, is chief executive officer and co-founder of Xenex Disinfection Services and previously co-founded Rackspace, which was taken private by Apollo for $4.3 billion.[2](https://www.tectonicventures.com/) Miller does not appear on the Fund III general partner: the Fund II filings list Tectonic Ventures GP II, LLC with Rhodes-Kropf and Miller as managing members, while the Fund III general partner, Tectonic Ventures GP III, LLC, lists only Rhodes-Kropf and Juan Luis Leungli.[1](https://www.sec.gov/Archives/edgar/data/2048545/0002048545-25-000003.txt) • [3](https://www.sec.gov/Archives/edgar/data/1821306/0001821305-21-000001.txt) The filings do not state when or why Miller's role changed.
Juan Luis Leungli is a general partner who joined the firm in 2017 from [General Catalyst](https://www.edgepedia.org/general-catalyst), where he focused on early-stage investing and led coverage of Boston startups, having previously worked at [Javelin Venture Partners](https://www.edgepedia.org/javelin-venture-partners). The New England Venture Capital Association named him "Rising Star in VC" in 2017.[2](https://www.tectonicventures.com/) Mark Weber is a partner at the firm specializing in AI, according to the firm's site.[2](https://www.tectonicventures.com/)
## Investment strategy
The firm describes itself as a seed-stage and early-stage investor that provides initial capital to mission-oriented entrepreneurs solving meaningful problems in the business world.[2](https://www.tectonicventures.com/) This framing is the company's own; independent reporting on check sizes, sector mandates, or geography is not available in the sources retrieved.
## Funds by the numbers
The firm's SEC Form D record shows a progression from a small first fund to a substantially larger second fund and a third fund still being raised at the end of 2025.
- **Fund II** (Tectonic Ventures II, L.P., with Tectonic Ventures Parallel II, L.P.): $87,103,000 sold, including $4,000,000 of cash contributed by the general partner, across 153 investors, with first sale on 2020-09-03; the fund relied on Investment Company Act Sections 3(c)(1) and 3(c)(7).[3](https://www.sec.gov/Archives/edgar/data/1821306/0001821305-21-000001.txt)
- **Tectonicana, LLC**: $5,870,011 sold to 59 investors, Form D filed 2021-08-20, an opportunity vehicle affiliated with Fund II and managed under Tectonic Ventures GP II, LLC.[6](https://www.sec.gov/Archives/edgar/data/1875503/0001875503-21-000001.txt)
- **Fund III** (Tectonic Ventures III, L.P., with Tectonic Ventures Parallel III, L.P.): $75,000,000 offered and sold in aggregate, of which $59,215,000 was sold by the main fund and $15,785,000 by the parallel vehicle, across 115 investors as of the amendment filed 2025-12-30.[1](https://www.sec.gov/Archives/edgar/data/2048545/0002048545-25-000003.txt) • [7](https://www.sec.gov/Archives/edgar/data/2048544/000204854425000003/0002048544-25-000003.txt) EDGAR shows the original Form D filed on 2024-12-16.[5](https://www.sec.gov/cgi-bin/browse-edgar?CIK=0002048545)
**Why parallel funds file separately.** Fund III is a pooled venture capital fund relying on Investment Company Act Section 3(c)(7), while the parallel vehicle Tectonic Ventures Parallel III, L.P. relies on Section 3(c)(1).[1](https://www.sec.gov/Archives/edgar/data/2048545/0002048545-25-000003.txt) • [7](https://www.sec.gov/Archives/edgar/data/2048544/000204854425000003/0002048544-25-000003.txt) The two vehicles file their own Form Ds but report their totals jointly, so the combined offering amount of $75 million appears on both filings, with $59,215,000 sold by the main fund and $15,785,000 by the parallel vehicle.[1](https://www.sec.gov/Archives/edgar/data/2048545/0002048545-25-000003.txt) • [7](https://www.sec.gov/Archives/edgar/data/2048544/000204854425000003/0002048544-25-000003.txt) Both vehicles share the same general partner, Tectonic Ventures GP III, LLC.[7](https://www.sec.gov/Archives/edgar/data/2048544/000204854425000003/0002048544-25-000003.txt)
Form D amounts are commitments sold, not assets under management; the sources do not state the firm's AUM or realized returns.
