Phosphor Capital, the venture firm founded by Y Combinator alumnus Kulveer Taggar, had raised $34 million across two funds and backed more than 200 YC companies by July 3, 2025, according to TechCrunch. YC CEO Garry Tan was among the fund’s investors. The report describes a launch-era snapshot, not Phosphor’s current assets, portfolio count, or investment activity.
What Phosphor Capital is—and what the $34 million figure means
Phosphor Capital was founded by Taggar after he left Zeus Living. TechCrunch reported that the firm launched in 2024 and had raised $34 million across two funds by July 2025. That figure is the reported amount raised across both funds; it is not a disclosed fund-by-fund breakdown, a statement of current assets under management, or a measure of returns.
The firm’s stated investment universe was companies that went through Y Combinator. Taggar expressed particular interest in young AI startups, but the report does not say Phosphor invests only in AI. Its reported check range was $100,000 to $500,000. By the report’s July 3, 2025 publication, Phosphor had backed more than 200 YC companies. The report does not establish a current count as of October 2026.
Who backed the fund?
Garry Tan, Y Combinator’s CEO, was an investor in Phosphor, according to TechCrunch. That means Tan invested in the fund; it does not establish that Y Combinator itself supplied capital. Taggar described the other backers as Zeus investors, family offices, and a large asset manager. The report does not name all limited partners, disclose the fund terms, or identify the manager.

- If you want to build a better future, you must believe in secrets.
- The great secret of our time is that there are still uncharted frontiers to explore and new inventions to create. In Zero to One, legendary entrepreneur and investor Peter Thiel shows how we can find singular ways to create those new things.
Taggar said, “You could view this as a bet on Garry. I think he is taking Y Combinator to new levels.” That is Taggar’s characterization of part of the investment thesis, not evidence that Tan manages Phosphor or that YC guarantees the fund’s results.
Why Taggar’s YC background matters
Taggar first went through YC in 2007 with Auctomatic, alongside his cousin Harj Taggar and future Stripe founders Patrick and John Collison. TechCrunch reported that Auctomatic was sold about a year later. Taggar returned to YC in 2011 with Zeus Living, a furnished-housing company offering flexible terms. Initialized Capital, co-founded by Tan, led Zeus Living’s Series A, and Tan joined its board.
Zeus Living was sold to Blueground in late 2023 for undisclosed terms. Taggar told TechCrunch that Zeus had reached a valuation above $200 million and an annual revenue run rate of about $120 million at its peak. Those are historical figures attributed to Taggar about Zeus Living; they are not Phosphor fund results or independently presented performance data.
YC partner Jared Friedman called Taggar “what you might call an OG alum from the early days of YC.” Friedman also said Zeus was “a really hard company to run” and that Taggar had “a tremendous number of battle scars from doing this hard thing in the physical world.” These are Friedman’s assessments of Taggar’s experience, rather than claims about investment performance.
Rank #3
What the strategy implies for founders and investors
A YC-only investment universe gives Phosphor a defined sourcing focus: companies in the YC network. The reported check range suggests the fund made relatively targeted investments across that community, but the report does not specify stages, ownership targets, follow-on policy, or selection criteria. A company’s YC participation alone should not be treated as evidence that Phosphor will invest.
TechCrunch named Gumloop and Circleback as Phosphor portfolio companies that had each subsequently raised a Series A by the time of the report. Those examples show that some backed companies progressed to a later funding round; they do not establish returns to Phosphor or predict the results of its broader portfolio.
Rank #4
Taggar told TechCrunch that “6% of YC companies become unicorns, and of that 6% a quarter become decacorns.” The article does not provide a cohort, methodology, or independent verification for that statistic. It should be read as Taggar’s claim, not as a verified base rate for YC companies or a forecast of Phosphor’s returns.

TechCrunch also identified Pioneer Fund and Rebel Fund as pursuing similar YC-focused approaches. It described Phosphor at the time as the only dedicated YC fund led by a solo GP. That comparison is specific to the article’s July 2025 reporting and is not a current market census.

What remains undisclosed
TechCrunch’s July 3, 2025 report is the basis for the figures and descriptions above. The information reported there does not establish Phosphor’s current assets or portfolio, subsequent activity, fund terms, full investor roster, or investment returns. The outlet also published a Yahoo Finance copy of the same reporting, which is not an independent confirmation.
