We’re excited to share that @jacobeffron has been promoted to Managing Director at Redpoint. Since joining the firm in 2020, Jacob has built a reputation as one of the most thoughtful and trusted voices in venture. His investments in companies such as @AbridgeHQ , @WeAreLegora, @getgarner, @ScribeHow, @AcuityMD, @tryramp, @physical_int, @poolsideai, @Deliverect_com, @StriveHealthUS and @ideogram_ai speak volumes about his ability to identify and support transformational teams. Great founders consistently seek Jacob out. He is known for his intellectual rigor, first-principles thinking, and relentless commitment to helping entrepreneurs succeed. He is not only a valued thought partner but someone whose insights and contributions materially shape the companies he works with. Internally, Jacob brings the same clarity and commitment that define his work with founders. He sharpens every discussion, builds conviction through outstanding diligence, carries himself without ego, and consistently leads by example. That combination of humility and intellectual drive is rare. Most importantly, he is a genuinely good person and a pleasure to work with. Jacob’s drive to create lasting, high-quality work can also be seen in his two podcasts—Vital Signs and Unsupervised Learning—focused on healthcare and AI, respectively. Both are trusted resources for founders, operators, and investors looking to understand and navigate the most important innovations of our time. In this business, few signals are clearer than the respect of great founders and the conviction of your partners. Jacob has earned both. We’re fortunate to call him a colleague, and even more excited for what lies ahead as we continue building with him. Congratulations, Jacob! - Scott, Elliot, Logan, Annie, Erica, Satish, and Alex

Remember reinforcement fine-tuning? We’ve been working away at it since last December, and it’s available today with OpenAI o4-mini! RFT uses chain-of-thought reasoning and task-specific grading to improve model performance—especially useful for complex domains. Take @AccordanceAI, which used RFT to fine-tune a model that’s SOTA for their tax and accounting purposes. And in supervised fine-tuning news: you can now fine-tune GPT-4.1 nano. Get even more from our fastest, cheapest model by training it specifically for your use-case.

We were horrified by the news and footage coming out of Israel this weekend, due to the barbaric terrorist attack by Hamas, which continues to have a reverberating impact in the region and around the world. To our founders, friends, the people of Israel, and Jewish communities worldwide: You are in our hearts and minds. We hope for a world where peace prevails over terror, and understanding triumphs over hatred. We are making donations to humanitarian causes to aid those who have been impacted.
