Forward engineering
We design the system around where your business is going, not only where it is today. The data model, integrations, and security boundaries are built so the next capability is an addition, not a rebuild.
Private AI for construction
Your data is your competitive advantage. We built Stellar to keep it that way.
Our mission is to protect the intellectual property of every company we work with by giving them an AI application that can safely access their own information without sharing a single record with frontier models or with their competitors.
We do this for construction companies.
- Your data never leaves your tenant.
- Trained on your estimates and bids.
- Actuals matched back to every bid.
- Agentic workers in 180 days.
Private intelligence / 01
A private LLM, built for how construction companies actually work.
Stellar starts where the money is decided: estimating, budgeting, and the bid process. We train a private model on your own historical estimates, bids, and outcomes, then connect it to a CRM your whole team can use.
From there, it follows the job. We match actuals back to estimates so you can see how a project really performed: bid versus margin, estimator versus outcome, and office versus office. That information is available to anyone with the security role required to see it.
Your model. Your data. Your building.
A tested LLM
The model is evaluated against your real work before anyone relies on it. We measure it against your estimates, bid history, and terminology because a model that is generally correct but wrong about your business is worse than no model at all.
A technology stack that holds up
Tenant isolation, role-based access, continuous synchronization workers, and an architecture that runs against live production CRM data every day. This is not a demo.
Construction intelligence / 02
The information your team needs, connected to the work.
Ask a question. Get the whole job back.
Everything about a job, in one place
Companies, contacts, job-site details, bid history, estimators, and award status are accessible to anyone in the company with the correct security role. There is no need to hunt through folders or wait for the one person who knows where the information lives.
Illustrative data
How did the Northlake renovation actually perform?
Get a detailed answer, not a list of files.
Every bid date, due date, and award date in one view.
Bid pipeline and calendar
Track the entire pipeline by day, week, or month. Filter by estimator, office, or status. See what is due, what is out, and what came back without putting a spreadsheet in the middle.
Calls, visits, and next steps, tracked without the paperwork.
Sales activity
Reps can log interactions quickly. Leadership can see completion rates, account coverage, and follow-up trends by rep and customer type. Key accounts stay active because follow-ups do not fall through.
Keep the systems your team already trusts.
Your systems stay. We connect to them.
Stellar synchronizes continuously with the systems your team already uses, including CRM records, projects, contacts, and estimate files. Data stays current without manual re-entry, and customers do not have to replace their existing systems to get started.
Reporting / 03
The most robust reporting tool in construction, and anyone can use it.
See bid volume by week and office, bid counts, top customers by award amount, won contracts, and scheduled reports that arrive in your inbox without requiring someone to build them manually.
Most importantly, Stellar matches actuals back to estimates. See how a job performed against the bid, including margin, variance, and where results changed, so the next estimate can be better than the last.
Stellar makes large datasets understandable and makes reporting available to everyone with the security privileges to see it, not only the person who owns the spreadsheet.
The 180-day arc / 04
In 180 days, you stop asking questions and start assigning work.
The first six months are about making your data clean, connected, and trustworthy, while helping your team get comfortable asking the system questions and receiving real answers.
Once the model knows your business, agentic workers can take on recurring tasks that previously seemed impractical: watching bid boards, flagging jobs drifting away from margin, assembling prequalification packages, and pursuing follow-ups that teams do not have time to chase manually.
Most companies do not believe this until month four. We are fine with that. We only ask you to start.

Protection / 05
Nothing you give us trains someone else's model.
Your model is yours. Your data stays inside your tenant, isolated from every other customer and never passed to a frontier model provider for training. Role-based access controls determine who inside your company can see each type of information.
Your estimating history, pricing intelligence, and customer relationships took years to build. They do not become someone else's advantage.
- Your modelBuilt around your historical work.
- Your tenantIsolated from every other customer.
- Your security rolesDetermine who can see each type of information.
