- Ladder Health
Participated · Seed · Jun 2026
Ladder Health delivers virtual-first, AI-enabled developmental and therapeutic care for children, providing speech, occupational, physical, and feeding therapy through a model that activates caregivers as therapeutic partners. The platform offers evenings and weekends access and emphasizes extending care into the home to reduce wait times from months to days. Ladder partners with pediatric practices and health systems as a referral and care-extension partner and reports working with more than 80 provider organizations and health systems across Massachusetts, North Carolina, and Maryland. The company was incubated by 25madison and developed in collaboration with clinical experts at Boston Children's Hospital, which holds equity in Ladder. Current plans highlighted by the company include geographic expansion into additional states and continued investment in its AI-enabled care platform and health system integrations.

- HLRBO
Led · Seed · Jun 2026
HLRBO operates an online marketplace for hunting leases, offering listing, discovery, secure payments, legal agreements, and integrated insurance to connect landowners and hunters. Founded in 2015 in Brainerd, Minnesota, the platform reports 14,000 paying subscribers, 225,000 total users, and 1.7 million acres of land leases across all 50 states. The company has grown from a regional startup into a national platform and has raised multiple rounds, including $600,000 and $1.0 million in 2024 and the recent $2.5 million round in 2026. HLRBO is investing its latest capital in technology upgrades—parcel-level mapping, AI land scoring, and a 3D “cinematic” view—alongside web/app improvements. It is also expanding media, education, trade-show presence, partnerships, and creator-driven social initiatives to increase engagement and inventory. These efforts aim to scale listings and user acquisition while building land intelligence and marketplace infrastructure.

Leadership changes include the appointment of Brian Tufts as CEO while founder Al Berning moves to Executive Chairman. The articles did not provide operating metrics such as revenue or user counts.
- When Insurance
Participated · Series A · Feb 2026
When, founded by Andy Hamilton and Dan Wertheimer and based in Chicago, offers a software platform that guides organizations and their employees through healthcare and benefits changes triggered by events such as early retirements, career pivots, involuntary exits, Medicare eligibility, and other coverage transitions. The solution aims to reduce employer costs while delivering personalized support to transitioning workers. Since its launch in 2024, more than 6,000 companies have adopted the platform, giving over 1 million employees access to its tools. Current functionality centers on simplifying benefits navigation, but the company plans to broaden its coverage to additional transition scenarios, including Medicare and early retirement pathways. Proceeds from its recent Series A will be used to expand the team and enhance product capabilities to serve a wider array of workforce transitions. The company’s traction across thousands of employers demonstrates early product-market fit and provides a growing revenue base, although specific revenue figures were not disclosed.
- Bonsai
Participated · Equity · Jul 2025
Bonsai has built a first-party marketing intelligence platform that ingests a brand’s own data and delivers unified business reporting, multi-touch attribution, marketing mix modeling, incrementality testing, budget forecasting, automated buying algorithms, and audience analytics in a single interface. The SaaS product integrates with more than 80 marketing and business systems, allowing brands to onboard quickly without the need for data engineers, tracking cookies, pixels, or custom code. By eliminating biased third-party conversion data, Bonsai gives marketers “extreme clarity” on what truly drives profitable growth. Early customers include 1-800-Flowers, Aspen Dental, Camping World, JSX, and Gabb Wireless, each using the tool to direct spend toward their highest-ROI channels. The Chicago-based company positions itself as a solution to the “measurement chaos” facing omnichannel marketers and claims it can automate incremental, profitable growth for consumer brands. Recent funding will be used to accelerate go-to-market expansion and further develop the platform’s capabilities. No revenue, user count, or other operating metrics were disclosed in the announcement.
