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
AI built around the way your business works
Your people know the work. We bring the engineering and design to turn that knowledge into tools they can use.
Make company knowledge easier to use
Build AI assistants that help staff find answers in your documents and processes. Keep the source material available so people can check the answers.
Automate the work between systems
Connect business software, spreadsheets and portals. Prepare files and handle repetitive steps while your team keeps review and approval decisions.
Give your team software that fits
Build portals and internal tools around the people who use them. We work through the process with your staff, design the screens and test the output together.
Help people use AI in their daily work
Run hands-on sessions around problems staff bring from their jobs. Help leaders understand where AI is useful and how to review its work.
How we work
Work with us from the first problem to daily use
Choose a useful starting point
We sit with the people who do the work, pick the task worth fixing first and agree how we’ll measure the result.
Build and test together
We connect your data and build the tool around your process, reviewing working software with your team as we go.
Help your team use it
We train your staff on real tasks, gather feedback and decide with you what to build next.

Questions
A few things you may be wondering
Where should we start?
Bring a recurring task, a process that slows your team down or an idea you want to explore. In a 30-minute conversation with Charles, we’ll discuss the work involved and where TCP could help.
Does every project need AI?
No. We choose the approach that fits the task. AI is great for answering questions about documents or drafting summaries; other work is better served by straightforward automation. Either way, your team reviews the output.
How do you handle our data and approvals?
We agree on access, permissions and data handling with your team before we start. Your team keeps the review and approval decisions.
What does it cost, and how long does it take?
We work in short sprints. Together we define a first project that shows value quickly, agree its scope and budget, then keep building from there as the results come in. For reference, Solstice’s budget portal went live nine weeks after kickoff, and its alterations portal had a first prototype after one week.
