  • Sensa

    Participated · Equity · Aug 2026

    Sensa builds a software platform that brings industrial context and data-quality controls to sensor and operational data for small and medium-sized industrial firms. The company emphasizes automated detection of sensor faults, data-quality signals and context enrichment so customers can trust inputs used for industrial AI. Founded in 2024, Sensa targets aquaculture, shipping and renewable energy customers and currently has four paying customers. The team includes six staff in Norway and six in Bangladesh via partner Cefalo. Management says the company’s near-term plan is to scale sales and expand customer deployment to drive adoption of its full platform. Financially, Sensa recently raised four million kroner in a round with Eviny Ventures, Tidligfasefond Vestland and Brothers, following a prior five million kroner injection from Startuplab and existing owners.

  • Assured

    Participated · Seed · Sep 2025

    Assured provides AI tools and agents that verify provider information across 2,000 primary sources, prepare applications to meet state and payer requirements, and flag missing information. The platform automates provider credentialing, licensing, payer enrollment and network management and can credential providers within days, get them in-network about 30% faster, and save operations teams dozens of hours weekly. Assured is a National Committee for Quality Assurance–certified Credentials Verification Organization, enabling it to conduct credentialing verifications directly for health systems and health plans. The company serves more than 100 healthcare organizations, including Houston Methodist. Founders built the product after experiencing 60+ day credentialing timelines while operating a previous telehealth startup. With the latest financing, Assured has $25 million in total funding and plans to grow engineering, product and go-to-market headcount.

  • Pixieray

    Participated · Series A · Apr 2025

    IXI is developing invisibly‑smart prescription eyewear that uses a small frame‑mounted device to track the wearer’s eyes and drive liquid crystal lenses to auto-focus for presbyopia. The glasses are designed to be low‑power with an estimated battery life of about two days; the lenses also include a near‑sighted prescription so wearers retain distance vision if the battery dies. IXI has filed and applied for multiple patents around its technology and declined to share detailed technical specifics in public. The company says its technology has been proven in labs and plans to show a prototype later this year, but it has not disclosed a market launch date or regulatory timeline. IXI’s team includes founders Niko Eiden and Ville Miettinen and many engineers who previously worked on mobile and mixed‑reality technology at Nokia and Varjo. The company argues the addressable eyewear market is large — cited estimates put it at over $200 billion and growing faster than smartwatches and smartphones. Pixieray is developing adaptive eyeglasses that continuously adjust focal point and optical power so wearers get optimal vision for whatever they are looking at, reducing eye strain versus fixed multifocal lenses. The company has a working prototype and says the product will not resemble VR or AR headsets. Pixieray plans to ship its first product in 2023 and expects to expand the team to about 10 people, hiring in the Helsinki region. The glasses can be adjusted by the wearer over time to match vision changes and significantly increase the clear field of view compared to multifocal lenses. Pixieray intends to partner with a manufacturer for production but will refine the technology beforehand. The founders include CEO Niko Eiden, COO Rebecca Xu, CTO Klaus Melakari and chief algorithm officer Ville Miettinen, with adviser Jocelyn Faubert; Eiden previously worked at Microsoft, Varjo, and CERN.

  • UpCodes

    Participated · Series A · May 2023

    UpCodes operates a searchable database of building codes and local amendments and offers tools such as code search, a code-check feature, and a new AI assistant called Copilot. Copilot, built on ChatGPT-4, answers jurisdiction-specific code questions, cites relevant code sections, and can generate checklists and calculations for compliance tasks. The platform hosts more than five million code sections and 160,000 local amendments, updating roughly 7,000 items per month. UpCodes reports more than 650,000 monthly active users and over 100 million page views; since 2021 its team has doubled and revenue has quadrupled. The company offers limited Copilot access on paid plans (three questions) with unlimited access available on UpCodes Professional or Enterprise add-ons. Future plans include hiring across engineering and other departments, expanding the code library, adding more AI features, and developing additional capabilities like project management. UpCodes offers a searchable building-code database with collaboration tools and automated compliance features. It launched UpCodes AI to scan 3D models using BIM data and alert architects to potential issues, and recently introduced a code calculator that answers common compliance questions for more than 40 states. The product serves about 500,000 monthly active users and paid customers including construction firms (Stantec, ARCO National), architecture firms (SOM, Ennead), Airbnb, Cornell University and SUNY. The company targets both industry professionals and lay users (homeowners, landlords, tenants, plumbers, electricians) who need straightforward compliance answers. UpCodes plans to use new funding to hire and accelerate feature development, including automating calculations and expanding access on mobile. The company has also been involved in litigation with the International Code Council; it won a dismissal of a false-advertising and unfair-competition claim and earlier secured a favorable ruling on posting codes as public domain/fair use while a copyright suit remains ongoing. UpCodes builds a searchable, constantly updated database of building regulations and has launched UpCodes AI, a plugin that uses artificial intelligence (including natural language processing) to scan BIM 3D models for code violations. The AI plugin currently supports recent versions of Autodesk Revit and the company plans to add ARCHICAD, SketchUp and IFC support in the future. UpCodes’ database draws directly from municipal regulations and is updated almost in real time, helping architects avoid costly rework caused by missed amendments. The company reports over 100,000 monthly active users and coverage of building codes in 26 states plus the District of Columbia. During private beta, UpCodes AI identified an average of about 27 violations per project. Founded in 2016 by Scott and Garrett Reynolds, the team recently hired Mark Vulfson as UpCodes AI’s technical lead.
