Gigafund

About

Gigafund is a venture capital firm founded in July 2017 by Luke Nosek and Stephen Oskoui, both formerly of Founders Fund ¹². The firm is headquartered in Austin, Texas ¹.

Luke Nosek co-founded PayPal, where he served as VP of Marketing and Strategy ¹. He subsequently co-founded Founders Fund with Peter Thiel and Ken Howery ¹. At Founders Fund, Nosek led the first venture capital investment in SpaceX in 2008 and has served on the SpaceX board since then ¹³. Stephen Oskoui was a Venture Partner at Founders Fund before co-founding Gigafund, and previously founded and served as CEO of Smiley Media, a performance-based marketing company that drove more than $1 billion in sales for its clients ¹⁴.

Gigafund was initially created with a focus on raising capital for SpaceX, and the firm has invested over $1 billion in SpaceX since its founding ¹². The firm subsequently expanded to invest in other companies ³.

Gigafund’s first fund (Gigafund 0, LP) raised $100 million in 2017 according to its SEC Form D filing ⁵. In November 2020, Gigafund 0.8, LP raised approximately $231 million from 31 investors ⁶. In July 2021, Gigafund 0.14, LP reported approximately $478 million in total sales ⁷. The firm employs a general counsel and chief compliance officer, Lemuel Anaejionu, who holds a JD and MBA from Columbia University ¹.

Stated Thesis

Gigafund publicly describes its mission as “backing the world’s most ambitious and transformative entrepreneurs” through “long-term concentrated investments in founders who are capable of growing with their companies and maximizing impact over a period of decades” ¹.

The firm states that before investing, it asks: “Do we expect this company to be one of the world’s most significant and transformative businesses 20 years from today? Also, will this founder stick with their company for that period of time and ensure that it achieves its full potential?” ¹⁸.

Gigafund says it invests “across all sectors, geographies, and stages” and deliberately avoids limiting its focus to specific industries, arguing that “truly transformative companies rarely fit into pre-defined boxes” ¹. The firm describes its approach as rooted in “first-principles thinking to solve major global problems” ¹⁸.

The firm states that “the difference between an average and an extraordinary business or entrepreneur becomes clear when looking out 20 years, which is why almost all of our funds will be invested into a handful of companies that we anticipate will become the world’s most significant” ⁸.

Inferred Thesis

Based on 18 verified portfolio investments, Gigafund’s actual investment behavior reveals a highly concentrated strategy overwhelmingly focused on capital-intensive, physical-world technology rather than software.

Sector distribution (18 verified investments): Space/transportation: 3 of 18 (17%) — SpaceX, The Boring Company, SWTCH; Biotech/life sciences: 4 of 18 (22%) — Neuralink, Emerald Cloud Lab, LabGenius, Gordian Biotechnology; Energy/nuclear: 1 of 18 (6%) — Last Energy; Manufacturing/hardware: 2 of 18 (11%) — Atomic Machines, Cover; AI/computing: 2 of 18 (11%) — Luminous Computing, Gauntlet AI; Insurance/fintech: 1 of 18 (6%) — Sana Benefits; Education: 1 of 18 (6%) — BloomTech; Media/entertainment: 1 of 18 (6%) — Angel Studios; Forensics/genomics: 1 of 18 (6%) — Othram; Labor marketplace: 1 of 18 (6%) — Veryable; Real estate/proptech: 1 of 18 (6%) — Sunroom Rentals.

Elon Musk connection: A defining feature of the portfolio is heavy concentration in Musk-affiliated ventures. SpaceX, Neuralink, The Boring Company, and xAI are all Musk companies, representing at least 4 of 18 investments (22%). The firm has invested over $1 billion in SpaceX alone ¹. This Musk-venture concentration is not explicitly highlighted in the firm’s stated thesis but is the dominant pattern in capital deployment.

Stage distribution: The firm invests across stages but has led multiple Series A and Series B rounds (Cover Series B at $60M ⁹, BloomTech Series C at $74M ¹⁰, Angel Studios at $47M ¹¹, Sana Benefits Series A at $20.8M ¹², Veryable Series A at $31.9M ¹³, Othram Series B at $18M ¹⁴).

Check sizes: Range widely from seed-stage investments to the $105M Luminous Computing Series A ¹⁵. The firm’s check sizes at $1M-$5M for smaller deals ² but scale significantly for high-conviction bets.

Geographic concentration: Austin, Texas features prominently — both the firm and several portfolio companies (Sana Benefits, Veryable, Gauntlet AI, Emerald Cloud Lab) are Austin-based ¹¹²¹³. Los Angeles (Cover), The Woodlands, TX (Othram), and San Francisco also appear.

Founder profile patterns: The firm favors founders applying first-principles thinking from adjacent domains rather than industry insiders. Examples include Synthego’s Paul Dabrowski (SpaceX engineer turned biotech founder) and Cover’s Alexis Rivas (architect applying manufacturing principles from Tesla/SpaceX) ⁸⁹.

Co-investor patterns: Founders Fund appears frequently as a co-investor (Cover, Sunroom Rentals, Gordian Biotechnology), reflecting the founders’ origins ⁹. Valor Equity Partners (Cover), Trust Ventures (Sana Benefits, Veryable, Sunroom Rentals), and Uncorrelated Ventures (Angel Studios) also appear multiple times ⁹¹¹¹².

Notable gap: Despite claiming to be sector-agnostic, the firm has no visible enterprise SaaS, consumer internet, or traditional software investments. The portfolio is entirely physical-world technology, hardware, and science-intensive businesses. The “sector-agnostic” framing understates a strong revealed preference for atoms over bits.

In Their Own Words

“I can’t make up my mind on a company until I have met the founder.” — Luke Nosek ²³

“You are getting married to these founders. It’s important to spend the time getting to know them and then truly committing long term.” — Luke Nosek ²³

“And the most important thing in the deployment of future tech is to have an incredibly talented entrepreneurial leader driving the adoption of the tech — it’s about the person, not as much the tech, to determine what happens in the future.” — Luke Nosek ⁸

“We had a mission at PayPal — which was to create a new financial system, a new world currency, and we failed. We were a financial success, but we didn’t succeed at the purpose of our company.” — Luke Nosek ⁸

“We back the world’s most transformative entrepreneurs and look forward to BloomTech leading the revolution in education that we’ve all been waiting for.” — Stephen Oskoui, on BloomTech investment ¹⁰

“Angel Studios helps creators build a direct relationship with their fans and produce meaningful and compelling content for hundreds of millions of people who have been underserved by the entertainment industry. We believe that Angel is on track to rewrite the rules of the media business and have a significant impact on culture.” — Stephen Oskoui, on Angel Studios investment ¹¹

“Sana’s disruptive model for health insurance empowers small businesses to both cut costs and improve employee benefits.” — Stephen Oskoui, on Sana Benefits investment ¹²

“Veryable is helping the U.S. regain its position as a manufacturing powerhouse. [CEO and Co-Founder Mike Kinder] and his team are thinking big, and they have the knowledge and the drive to back up their ambition.” — Stephen Oskoui, on Veryable investment ¹³

“The process of building homes has been stagnant for decades, and we need to fix that in order to make housing more affordable.” — Stephen Oskoui, on Cover investment ⁹

“Far too many violent crimes remain unsolved. Othram’s technology has helped investigators close an impressive number of cold cases…” — Stephen Oskoui, on Othram investment ¹⁴

“Sector is irrelevant. Scale of ambition is what matters.” — Stephen Oskoui ⁴

“We’ve spent nearly 10 years developing the -1 to 0 philosophy because we firmly believe it’s when your company actually starts. Not with an idea, but when ambition takes hold.” — Stephen Oskoui ⁴

What Founders Say

“This raise gives us more than funding; it gives us key strategic partners. Gigafund and Uncorrelated will help us realize our long-term mission of remaking the entertainment industry.” — Neal Harmon, CEO of Angel Studios, on the $47M round led by Gigafund, January 2022 ¹¹

“We have an incredible group of investors who are all experts in some facet of our business, and their desire to continue to invest in us is a strong affirmation that Sana is offering a great solution to a big problem.” — Will Young, CEO and Co-Founder of Sana Benefits, referencing Gigafund’s participation across four rounds of investment ¹⁹

Bret Kugelmass, CEO of Last Energy, described Luke Nosek and Stephen Oskoui as “amazing to work with” in discussing Gigafund’s investment in Last Energy ⁸.

Stephen Oskoui noted that Cover’s founders resisted pressure to scale prematurely: “There are ways they could have scaled up much faster to appeal to investors, but wouldn’t have set them up for long-term success. We like the fact that they ignored the noise of a frothy Silicon Valley environment.” — Stephen Oskoui, commenting on Cover’s approach, though this reflects the investor’s perspective on the founder’s behavior rather than a direct founder testimonial ⁹.
