Be early to startups before they hire.

Undecimal Bio

Undecimal Bio is developing a way to deliver gene-silencing medicines beyond the liver, where RNA treatments have seen their strongest clinical progress. The Cambridge-based biotechnology spin-out from Eleven Therapeutics is initially applying its DELiveri platform to renovascular diseases. The company has raised $18 million in Seed funding co-led by 4BIO Capital and IQ Capital. Verve Ventures, Harel Tech, Entree Capital, Kerna Ventures, and Saras Capital also participated in the round. DELiveri combines large-scale screening of delivery molecules with AI analysis to identify structures that can carry small interfering RNA, or siRNA, into specific cell types. That could help address a central limitation in RNA medicines, which can silence the right gene but still fail to reach the tissue where it is active. Founded in 2026, Undecimal Bio is led by co-founders Dr. Yaniv Erlich and Shaul Ilan. The company will use the financing to expand DELiveri, advance its renovascular programs, and hire additional staff for its laboratories at the Cancer Research UK Cambridge Institute.

Marklo

Burlingame, California-based Marklo is building an agentic marketing platform that helps Shopify brands decide what to promote next. It connects sales, inventory, campaign history, market signals and marketing tools, then proposes cross-channel campaigns for marketers to review and approve. The company has raised $5 million in seed funding led by Forerunner, with participation from Freestyle Capital. Marklo also opened its public beta as brands prepare for the holiday shopping season, offering a shared workspace for planning calendars, campaigns, tasks and performance. Founded by Jessica Herrin and Scott Royston, Marklo is already used by direct-to-consumer brands including Away, Clare V., Monica + Andy, Maya Brenner and Latico Leathers. The platform integrates with tools such as Shopify, Klaviyo, Attentive, Meta, Google, Slack, Canva and Figma, bringing fragmented commercial and marketing data into one view. Marklo says its system can surface opportunities such as slow-moving inventory or underused products, then help assemble the related campaign work. Latico Leathers used the platform to plan a month of marketing in one day, according to the company. Marklo will use the financing to hire across product and engineering, expand the public beta, and invest in customer success and community programs.

Salience Labs

Oxford, UK-based Salience Labs develops photonic chips and optical circuit switching technology that helps connect GPUs inside AI data centres. By moving data between processors through optical systems, the company is addressing a key infrastructure challenge as AI workloads demand faster, more efficient networking. The startup has raised $125 million in Series B funding led by Bullhound Capital. AMD Ventures, Intel Capital, SBI Group, Hudson River Trading, British Business Bank, Applied Ventures, Oxford Science Enterprises, Cambridge Innovation Capital, and Silicon Catalyst Ventures also participated. Salience Labs was founded by Vaysh Kewada and Johannes Feldmann. The round will fund deployment of its optical switching technology, expansion of high-volume manufacturing, and development of next-generation optical switches. Salience Labs has demonstrated a 64-port all-optical photonic switch and is developing 128-port and 256-port versions for larger-scale data centre connectivity. The company is working with Keysight Technologies and Tower Semiconductor to scale manufacturing. It will also grow its engineering team, expand into additional geographic markets, and establish a second West Coast location as it takes the products into wider deployment.
