What Proof Should a GC Ask For Before Sending Drawings to a Startup?
Helonic is an AI construction drawing analysis platform for cautious general contractors deciding whether to send drawings to a startup AI drawing review vendor. "We cannot send drawings to a startup" is a reasonable starting position. Most AI drawing review vendors are young companies. The useful move is to name the specific risks behind the worry and ask for proof against each one.
Direct answer. Before sending drawings to Helonic or any startup vendor, a cautious GC should get five things in writing: a SOC 2 report or summary, the hosting region and subprocessors, a no-training statement, a deletion term, and an export path if the company shuts down. Then start with a closed-out set and one reference call from a contractor of similar size.
What is the worry, exactly?
Two separate things get lumped together. One is data handling: whether the files are protected, used, and deleted properly. That risk is the same for any vendor of any size. The other is continuity: whether the company will be around next year, and what happens to your files if it is not.
Split them, and both become answerable. The first is a security review. The second is a contract term.
What proof answers each risk?
| Risk | Ask for |
|---|---|
| Files leak or are mishandled | A current SOC 2 report or summary, and named encryption standards |
| Files train someone else's model | A written statement that customer drawings are not used for training |
| Nobody knows where files sit | Hosting provider, region, and the subprocessor list |
| Files linger after you leave | A deletion term, with written confirmation when it happens |
| The company shuts down or is acquired | An export path, notice terms, and deletion obligations that survive a change of control |
A SOC 2 report means an independent auditor tested the vendor's controls, which matters more for a young company than a long list of promises. How to read the answers is in what a security questionnaire should get back.
What covers the vendor going away?
- An export of findings in a format you can open without the vendor, such as PDF or Excel.
- Deletion obligations that hold through an acquisition or shutdown.
- Notice before the service ends, long enough to finish the current bid.
- A project or annual term instead of a multi-year prepay.
The export and deletion side is covered in what happens to drawings when the subscription ends, and the contract language in what legal wants in the contract.
How do you start without betting a live job?
Send a closed-out set first. It has no active owner confidentiality issue, and your team already knows what went wrong on it, which makes it the best test anyway. Move to a live bid only after the security review clears. The boundary for that first live job is in how to run one bid without a company rollout.
For reference, Helonic is backed by Y Combinator, is SOC 2 compliant, encrypts files in transit and at rest, and does not train AI models on customer data, per its security page and AI policy. The pilot steps are in how to pilot AI drawing review software, and security sits with the other buying criteria in what to look for in an AI construction drawing review platform.
Practitioner insight
“Our CFO's first question was what happens if they go under. Fair. We got deletion and export written in, started on a job we closed out last year, and that was enough to get the next one approved.”
