- SageOx
Participated · Seed · May 2026
SageOx provides a context layer that captures decisions, intent, and history across conversations, chat, coding sessions, and existing tools, turning that information into structured knowledge fed into agent interactions. Its platform aims to keep humans and AI agents aligned by enabling agents to pick up work with awareness of prior decisions and team conventions. The company has adopted an "open work" model and is working with early design partners to validate its approach. SageOx was founded in 2026 by Ajit Banerjee, Ryan Snodgrass, and Milkana Brace, a team with deep experience building foundational systems across AWS, Apple, Facebook, and prior startups. The company plans to remain intentionally lean while using seed funding to continue product development and hire a small number of key roles.
- Starfish Space
Participated · Series B · Apr 2026
Starfish Space develops in-space infrastructure and satellite-servicing missions, including its Otter program and earlier efforts like Remora and Otter Pup 2. The company has announced commercial and government contracts, naming the Space Development Agency and the U.S. Space Force as customers. Starfish plans to fly its first full Otter mission later this year. The firm is scaling operations and hiring to support growing customer demand. Recent funding from its Series B will finance mission build-and-operate activities and team expansion. The articles did not provide information on revenue, user metrics, founding year, or location.
- Certivo
Participated · Seed · Feb 2026
Certivo is building an AI-powered Compliance System of Record that replaces manual, fragmented compliance workflows with continuously operating intelligent automation. Its platform deploys an AI agent called CORA to automatically request, validate, and normalize supplier documentation, map regulatory obligations to product portfolios, and integrate data into ERP, PLM, and procurement systems. The system also monitors regulatory changes across jurisdictions in real time, shifting organizations from periodic, reactive reporting to continuous compliance operations. Certivo is initially targeting the built-world sector—manufacturers, contractors, and owners of construction projects—where evolving safety codes, PFAS regulations, and sustainability mandates are creating intense compliance complexity. Headquartered in Seattle, the company positions compliance as a strategic advantage that safeguards market access and corporate reputation. While still at the seed stage, the new capital will be used to accelerate product development, expand engineering and AI capabilities, and scale go-to-market efforts. No revenue or user metrics were disclosed in the announcement.
- BluePill
Participated · Seed · Nov 2025
BluePill builds AI-driven “digital-twin” consumers that simulate how real audiences react to products, campaigns, and ideas in minutes, eliminating weeks-long traditional market-research processes. The system is trained on millions of behavioral data points, survey responses, and interviews, and its simulations show over 90 % alignment with live human panels while cutting research costs by roughly 90 %. Early customers in CPG, media, entertainment, healthcare, and sports—including Kettle & Fire, Magic Spoon, and the Seattle Mariners—use the platform to validate flavors, packaging, and fan-engagement strategies. Human benchmarking remains in the loop to ensure accuracy and mitigate AI bias. With fresh seed funding, the company plans to roll out vertical-specific AI audiences across CPG, healthcare, sports, media, and entertainment. BluePill touts the ability to give brands an “always-on focus group” that scales far beyond conventional surveys or focus groups. The company is currently financed by $6 million in seed capital from Ubiquity Ventures, Pioneer Square Labs, and Flying Fish Ventures, positioning it for continued product development and customer acquisition.
- Tin Can
Participated · Equity · Sep 2025
Tin Can is a Seattle hardware startup that sells screen-free, Wi-Fi–enabled landline-style telephones designed specifically for children. The devices operate on a private network and pair with a companion app, giving parents modern safety controls while eliminating the addictive elements of smartphones and social media. Since the flagship product’s launch earlier in 2025, the company has gone viral, selling out its first two production runs and amassing a wait-list approaching six figures. Tin Can currently employs 17 people and reports that demand continues to outstrip supply. The new capital will be used to ramp up manufacturing capacity, hire additional engineers and customer-support staff, and begin laying the groundwork for international expansion. Co-founders Chet Kittleson (CEO), Graeme Davies, and Max Blumen previously worked together at the real-estate startup Far Homes.
