In July 2022, in Washington, D.C., Ressio Software did not arrive with a grand manifesto. It arrived with a renovation hangover. Ryan Yu Liu was standing in Jersey City in 2021, staring at a residential remodel that had blown past budget and schedule, the kind of slow bleed every builder and homeowner knows too well. Spreadsheets everywhere. Emails nowhere useful. Software that promised control but delivered friction. That frustration turned into a conversation with Mitchell Kasselman, fresh off operational and business development work at ServiceChannel before its $1.2 billion acquisition by Fortive. The problem was obvious. The solution had to be better than obvious.
Ressio Software was built for residential builders doing real volume, not theory. Custom builders, spec builders, remodelers, specialty contractors running $3 million to $20 million businesses who are tired of tools that feel like they were designed by people who have never walked a job site. Ressio went after estimating, scheduling, budgeting, selections, documentation, client communication, and financial tracking with a single modern platform. No duct-tape workflows. No relic interfaces. Just software that respects time and margins.
That clarity just got capital. Ressio closed an $8.75 million Series A in late January 2026, led by Blueprint Equity out of La Jolla, California. Blueprint Equity, founded by Sheldon Lewis and Bobby Ocampo, does not chase noise. They back capital-efficient software with revenue discipline and real adoption. They had just closed a $333 million fund in twelve days when they leaned into Ressio, citing product execution and customer traction as the tell. This round brings Ressio to $11.75 million raised since the $3 million seed in October 2023.
The product tells the story louder than the press. Mason, Ressio’s AI assistant, does not pitch. It works. Ask it about budgets, schedules, risks, and task backlogs and it answers with live project data. It builds task lists, logs site activity, generates summaries, and surfaces problems before they metastasize. Builders report saving three to five hours a week, which in construction time is real money. The platform even migrates data from competitors while jobs are in progress, a quiet flex that removes the biggest excuse to stay stuck.
Mitchell Kasselman and Ryan Yu Liu are scaling with intent. Headcount sits around twenty three and is expected to double. Engineering leadership under Chad Calhoun is built for velocity, not vanity. Community and education under Marie Darling reinforces adoption where most software dies. Blueprint Equity’s playbook will sharpen go to market while the product keeps getting smarter.
