Your property team has better things to do than copy data
TCP connects your existing systems and builds software and AI tools around the work your team does every day.
Talk through a workflowCase studySolstice · Property management
Annual budgets for 118 buildings. Live in nine weeks
236+
analyst hours saved in the first 100 days
Solstice manages over 100 New York co-ops and condos in Vantaca. Every budget season, analysts still pulled numbers by hand from Vantaca, utility portals, banks and tax records.
TCP built the Budget Portal. Pick a building and AI gathers the data, fills the finance team’s workbook and drafts the balance letter. Analysts just review.
- Hours of copy and paste for each of 100+ buildings. Analysts pulled reports from each system, retyped the numbers into the workbook and wrote the balance letter by hand.
- From hours of copying to one click. AI gathers the data, builds the workbook and drafts the balance letter in under five minutes. Analysts review instead of retyping.

How the Budget Portal works
Start with the building that needs a budget

Gather the inputs. Prepare the familiar output

Keep the analyst’s experience in the process

What we build
Start with the work that keeps landing back on someone’s desk
Budget preparation is one example. We look for the repeated collection, entry and follow-up work across your portfolio.
Connect the systems you already use
Bring information from business systems, portals and spreadsheets into the workflow that needs it. We assess access and integration options for your setup.
Build tools around your process
Give staff a shared place to collect documents, track progress and prepare outputs. At Solstice, Finance receives the budget workbook in its familiar format.
Put AI to work on documents
Summarize files and draft review checklists with source material available for staff to check. Solstice’s alterations pilot is an example; its benefits are still being validated.
Help your people use it
Train leaders and staff on the tools and workflows they will use. Improve the result with their feedback as it becomes part of daily work.
How we work
One workflow, from the first conversation to everyday use
Look at the work
Walk through a real task with the people who do it. Identify the systems, handoffs and repetitive steps.
Build and check it together
Connect the data and build the tool. Test the output with your team’s actual requirements before expanding its use.
Train the team and improve
Help staff use the workflow, respond to their feedback and agree what to tackle next.
Don’t have an internal development team? TCP can be yours, working like a startup inside your organization to build and ship new ideas.

Questions
A few things you may be wondering
We already have property management software. Where does TCP fit?
Look at the work that still happens between that software, spreadsheets and email. At Solstice, TCP connected existing systems and prepared the files Finance already used.
Does every workflow need AI?
We choose the approach to fit the task. Solstice’s budget preparation uses rules-based automation. AI can help with document summaries and draft checklists, with staff reviewing the output.
Who reviews the output and controls access to our data?
Your team keeps the review and approval decisions. We agree access, permissions and data handling with your team before implementation.
What does it cost, and how long does it take?
Both depend on the workflow, system access and scope. For reference, Solstice’s budget portal went live nine weeks after kickoff, and its alterations portal had a first prototype after one week. Start with a 30-minute call with Charles.
