About
Together AI was founded in 2022 with a mission to build the leading open-source AI cloud—a platform where developers and enterprises can train, fine-tune, and run inference on open-weight models without the constraints and costs of proprietary AI APIs. The company recognized early that as powerful open-weight models like Llama, Mistral, and FLUX proliferated, there was a massive opportunity to provide optimized infrastructure for running and customizing them. Together AI built a multi-cloud GPU platform with custom inference kernels and distributed training optimizations specifically engineered for open-source models.\n\nTogether AI's platform offers fine-tuning, inference, and training services across a curated library of leading open-weight models, with performance-optimized endpoints that often outperform what users can achieve running models on general-purpose cloud infrastructure. The company targets AI engineers, ML researchers, and enterprises that want flexibility—either for cost reasons, privacy requirements, or the need to customize model behavior through fine-tuning. Together's API design closely mirrors OpenAI's, making migration straightforward. Its pricing is consistently below proprietary model APIs for comparable capability tiers.\n\nTogether AI has achieved $300M in annualized revenue as of September 2025, growing to a $3.3B valuation with $533M in total funding. Investors include NVIDIA, Salesforce, and Kleiner Perkins—a combination that provides both strategic GPU supply chain relationships and enterprise go-to-market leverage. The open-source AI cloud market is a significant and growing segment as enterprises prioritize model flexibility and cost control alongside the maturation of open-weight models that increasingly compete with frontier proprietary models.
German AI translation leader with $185M revenue in 2024; raised $300M Series C at $2B valuation; exploring $5B IPO in 2026; enterprise language AI suite used by 100,000+ companies for translation, writing, and localization at scale.
About
DeepL is a German AI language technology company founded in 2017 in Cologne, emerging from the research team behind Linguee, the translation search engine. DeepL built its reputation on translation quality that consistently outperformed Google Translate and Microsoft Translator in independent benchmarks, particularly for European language pairs. The company's neural machine translation models are trained on a curated parallel corpus of high-quality translated text, producing output with natural fluency and contextual accuracy that approaches professional human translation for many use cases.\n\nDeepL's product portfolio has expanded beyond its flagship translation tool into a full enterprise language AI suite. DeepL Write provides AI-powered writing improvement and style refinement. DeepL API allows developers to integrate translation into applications, websites, and enterprise workflows. DeepL Pro offers team and enterprise plans with data security guarantees, including options for data not to be stored or used for model training — critical for industries handling confidential content. The company serves customers across legal, financial, pharmaceutical, and government sectors where translation accuracy and data privacy are non-negotiable requirements.\n\nDeepL reported $185M in revenue in 2024 and raised a $300M Series C at a $2B valuation, with reports indicating the company is exploring an IPO at a potential $5B valuation in 2026. The company employs 1,570 people and is one of the most commercially successful AI language companies in Europe. DeepL competes with Google Cloud Translation, Microsoft Azure Cognitive Services, and Amazon Translate at the API level, differentiating through superior output quality and enterprise-focused data privacy controls.
