The $100 million round at a $1 billion valuation was reported, not confirmed as completed. On September 20, 2024, TechCrunch said unnamed sources described Black Forest Labs as closing a financing on those terms, while warning that the deal was not final and could change. The company later announced a different, confirmed milestone: a $300 million Series B at a $3.25 billion post-money valuation on December 1, 2025.
What the September 2024 report actually said
TechCrunch’s September 20, 2024 report said unnamed sources had heard Black Forest Labs was raising or closing roughly $100 million at a $1 billion valuation. The report expressly cautioned that the financing was not final and the terms could change. Neither Black Forest Labs nor the possible investor publicly confirmed those terms in the report.
That distinction matters. A financing target or proposed valuation is not the same as a signed, completed round, and the available public record does not establish that the precise $100 million round closed at exactly $1 billion. TechCrunch also said one source mentioned Lightspeed as a possible participant, but the investor roster was unclear. Lightspeed was not confirmed as an investor in that reported financing.
Why Black Forest Labs drew investor attention
FLUX.1 and the founders’ background
Black Forest Labs emerged from stealth in August 2024 as a German generative-AI startup focused on image models. Its founders included CEO Robin Rombach, Andreas Blattmann, and Patrick Esser, researchers associated with latent-diffusion and Stable Diffusion work. The company announced $31 million in initial funding, reportedly led by Andreessen Horowitz. Contemporaneous coverage connected the team and its FLUX.1 model to the sudden interest in the startup.

Grok offered high-profile distribution
xAI announced that Grok’s early image-generation capability used Black Forest Labs’ FLUX.1 model. That gave the startup exposure through X and Grok, while giving xAI access to a prominent image model soon after Black Forest Labs’ launch. “Powered by” describes a reported product integration; it does not mean Black Forest Labs was owned by xAI. The public reporting cited here does not establish which FLUX.1 variant or serving architecture Grok used.
A sharp implied step-up—but not proof of business performance
TechCrunch reported that the earlier $31 million financing had a post-money valuation of about $150 million. Compared with that figure, the reported $1 billion valuation would have represented a large increase if the 2024 terms had been completed as described. The comparison is indicative rather than definitive: the 2024 figure was prospective and its valuation basis was not confirmed in the same way as the later Series B. A valuation is a market signal, not evidence by itself of revenue, profitability, or technical superiority.

The later confirmed financing
On December 1, 2025, Black Forest Labs announced a $300 million Series B at a $3.25 billion post-money valuation. The company named Salesforce Ventures and Anjney Midha’s AMP as co-leads. It said existing investors—including Andreessen Horowitz, NVIDIA, Northzone, Creandum, Earlybird VC, BroadLight Capital, and General Catalyst—were participating or increasing their involvement; additional participants included Temasek, Bain Capital Ventures, Air Street Capital, Visionaries Club, Canva, and Figma Ventures. The terms are in the company’s Series B announcement.
A financing release said total funding exceeded $450 million, counting the previously unannounced Series A as well as the Series B. That total and the undisclosed Series A are described in the December 2025 release. The $3.25 billion figure is the post-money valuation announced for that Series B—not a continuously updated public-market value.

From a Grok integration to a broader visual-AI supplier
By its Series B announcement, Black Forest Labs described its business in terms of visual intelligence, not only image generation. The company said its models were used by or integrated with Adobe, Canva, Meta, and Microsoft, and that enterprise models were available through infrastructure providers including fal.ai, Replicate, and Together AI. This suggests a business spread across model access, enterprise use, and platform distribution rather than dependence on one high-profile integration.
That strategy has a practical trade-off. Broad model availability can help attract developers and creators, while hosted, licensed, and enterprise offerings can create commercial routes beyond open adoption. But training and serving models are costly, platforms can build competing systems internally, and licensing, copyright, and provenance questions remain material risks for the generative-media sector. The company’s financing does not settle those business or product questions.
Rank #4
What became of the xAI relationship
Later reporting indicates the original xAI and Black Forest Labs collaboration ended after xAI developed its own image-generation models. WIRED reported in 2026, citing people familiar with the matter, that xAI later approached Black Forest Labs about licensing its technology again and that Black Forest Labs declined, with operational difficulty cited. Neither point should be treated as a company-confirmed account: they are WIRED’s reporting based on sources familiar with the matter.
The history is also a reminder that model capability, product moderation, and distribution are separate issues. The fact that FLUX.1 was used in an early Grok image feature does not establish that every output reflected Black Forest Labs’ own product policies or that the companies shared ownership or control.

How to read the two valuation figures
- $1 billion: a prospective valuation in a September 2024 report based on unnamed sources; the exact round terms and completion were not established.
- $3.25 billion post-money: the valuation Black Forest Labs announced for its $300 million Series B on December 1, 2025.
These figures describe different moments and different levels of confirmation. The later Series B establishes a subsequent financing milestone; it does not retroactively prove that the earlier reported round closed on its reported terms.
