SIGBOT
Your subcontractor
database, on autopilot.
Sigbot reads every email your team receives and automatically builds a live, searchable database of every subcontractor, supplier, architect, and developer you work with. Zero data entry. Ever.
Intelligent Extraction
From inbox to contact database
Every email you receive is scanned in real-time. Signatures are parsed, verified, and saved automatically.
The Problem
Construction runs on relationships.
Your contact data doesn't.
Every project brings dozens of new contacts. Most of them never make it into your database — and when you need them again, they're buried in an inbox or gone entirely.
Thousands of emails, zero structure
A single commercial project generates thousands of emails weekly across GCs, subs, suppliers, and consultants. Critical contact details are trapped in inboxes, never captured.
Subcontractors change constantly
Estimators move between firms. Project managers get promoted. Phone numbers change. Your contact list from 18 months ago is already half-useless when you need it for the next bid.
CRM data entry never gets done
Your team is on-site, not at a desk logging contacts into Salesforce. CRM adoption fails in over 60% of construction firms — not because the tools are bad, but because nobody has time to feed them.
Bid day chaos
When a new tender lands, you need to send Invitations to Bid to 50 subcontractors immediately. If your database is outdated, emails bounce, calls go to wrong numbers, and you lose the bid.
See It In Action
Signature in. Contact out.
Sigbot reads the signature block at the bottom of any email and extracts every field automatically.
Who It's Built For
Every role that depends on knowing who to call.
Chief Estimators & Preconstruction Managers
Mid-to-large GCs tendering commercial & residential projects
"When a tender lands, I need to send ITBs to 60 subs immediately. Half my contacts are outdated — emails bounce, numbers are wrong. We lose bids because we can't get pricing fast enough."
Sigbot builds a self-updating subcontractor database from your inbox. Every electrical, mechanical, and civil sub who emails you is captured automatically — with their latest contact details, always current.
Business Development Directors
Architecture, engineering & specialist consultancy firms
"Our relationship data is scattered across 12 project managers' inboxes. When someone leaves the firm, we lose their entire network. We have no firm-wide view of who we know."
Sigbot creates a firm-wide contact intelligence layer — scanning every team member's inbox to build a single, searchable rolodex of every developer, GC, and consultant your firm has ever worked with.
Sales & Estimating Teams
Electrical, mechanical, civil, and specialist trade contractors
"We quote 40 projects a month. Every GC we quote has a different estimator, project manager, and procurement contact. We can never keep track of who to follow up with."
Every GC contact who emails your estimating team is automatically captured and tagged by project and trade type — so your sales team always knows who to call for the next bid.
Development Managers & Procurement Teams
Residential, commercial & mixed-use developers
"We manage 8 projects simultaneously, each with its own consultant team. Keeping track of 200+ contacts across architects, engineers, and contractors is a full-time job in itself."
Sigbot automatically organises contacts by project and role — so you always know exactly who the structural engineer, planning consultant, or M&E coordinator is on each scheme.
How It Works
A controlled pipeline from signature capture to clean contact records.
Capture signatures
Pull signature blocks from Outlook, Gmail, and IMAP email threads without interrupting the inbox workflow.
Structure the data
Normalise names, roles, companies, phone numbers, and other fields into a consistent schema — ready for any CRM.
Review and export
Confirm new contacts inside a focused dashboard before sending them into Procore, HubSpot, or your CRM process.
Integrations
Plugs into your existing stack.
Sigbot pushes contacts directly into the tools your team already uses — no migration, no disruption.
We send out 60 Invitations to Bid every time a new project lands. Before Sigbot, half those emails bounced because our subcontractor list was 18 months out of date. Now it updates itself.
