The NationGraph alternative
built for public construction.
Signal is pre-bid intelligence built for one job: winning public construction. NationGraph is pre-RFP SLED intelligence — it cites the source public record behind each signal, across every category a government buys. Signal does the same source-backed work, but for one vertical all the way down. You get the pipeline modeled by trade. You get the owner → architect → engineer → CM map on every project. And briefs, priced by your territory.
Both cite the record behind the signal. That part is a tie. Only one models your trade and maps the people who decide the job. NationGraph reads every SLED category — so you buy the whole map to reach the construction sliver that is actually yours.
The construction gap
Both cite the signal before the RFP. Only one is built to help you win the construction job.
Built for all of SLED, not construction
NationGraph reads pre-RFP signals across everything a government buys — IT, services, facilities, construction. Public construction is one category on a horizontal platform. It is not the model the platform is built around.
Cited records, not a construction stakeholder web
NationGraph cites the public record behind each signal, which is real research value. A construction pursuit turns on a different chain. You need the owner, the architect, the engineer, and the CM on one project — with roles, per pursuit.
Not modeled by trade
A public HVAC job, a roof replacement, and an athletic-field rebuild are different pipelines. Different buyers. Different cycles. Signal models each trade. A horizontal tool flattens them into one "construction" tag.
Breadth over construction depth
NationGraph spans every SLED category with source-cited signals. Signal goes deep on public construction instead — live project counts, source-backed briefs, and stakeholder maps by trade and territory.
The construction pipeline is real and specific. Across Sympl's tracked dataset (July 2026), the median public construction project leaves its first pre-bid record 397 days before the bid posts — then the bid window runs a median of 31 days.
Two shapes of the same idea
NationGraph cites the signal across all of SLED. Signal does it for one market — public construction.
NationGraph
Horizontal SLED intelligence
One platform for any vendor selling to state and local government. It reads pre-RFP signals and cites the source public record behind each one, across every buying category. That research trail is its strength. Construction is one lens among many.
Sympl · Signal
Construction-native pre-bid intelligence
The public construction pipeline, modeled by trade and mapped by territory. You see who is planning the work. You see which firms own each layer. You get the owner → A/E → CM chain to reach — with the source behind every signal.
If you qualify across categories, breadth wins. If you sell public construction, depth wins.
At a glance
Sympl · Signal vs NationGraph
For public-construction pursuit specifically. Where NationGraph is the stronger fit, we say so.
One honest concession: NationGraph covers every SLED category. Signal is construction-only. If you qualify across categories — IT, services, facilities, construction — its source-cited research covers more ground. The citation is a tie, not the wedge. Signal models your trade and maps the people who decide the job.
For construction, it's not close
If your business is public construction, choose Signal.
- You want the pipeline modeled by your trade and mapped to your territory — not one "construction" filter on a national SLED database.
- You need the owner → A/E → CM chain on every project, with the source behind each signal.
- You want to pay for public construction, and see the price before you talk to sales.
NationGraph is the better pick only if you qualify across every SLED category — IT, services, facilities, construction, all of it. If you build, Signal is the one built for you.
Cost
How much does NationGraph cost?
NationGraph prices on a quote basis — you talk to sales for a number. That fits a horizontal platform sold across every SLED category. But you are buying research coverage built for all of government. You still have to find the construction work inside it. The pipeline is never modeled the way you bid.
How Sympl · Signal pricing compares
Signal publishes its pricing: region-based territory tiers, so the cost tracks the footprint you cover. A regional contractor pays for its own market, not a national all-category database. See the number for your territory on the Signal pricing page before talking to us.
The same gap, other tools
Horizontal SLED tools flatten construction into one category.
CivicIQ
AI sales intelligence across all of SLED. Broad category coverage, not modeled by construction trade.
Starbridge
End-to-end GTM stack for government and education. Broad outreach engine, not construction-native.
GovWin IQ
Broad federal + SLED solicitations. Strong at RFP stage, not construction-native.
Signal covers one category all the way down: trade, territory, stakeholders, and the source behind each signal.

Frequently asked questions
Is Sympl · Signal a NationGraph alternative?
Yes — for public-construction pursuit. NationGraph is horizontal SLED intelligence: it detects pre-RFP signals and cites the source public record behind each one, across every government buying category. Sympl · Signal does that same source-backed pre-RFP work for one vertical — public construction — modeled by trade, with a per-project stakeholder map.
Does NationGraph cover construction?
Yes, as one category. NationGraph surfaces construction signals alongside IT, services, and facilities across all of SLED, and cites the record behind each. Signal covers only public construction, but models it by trade and maps the owner → architect → engineer → CM chain on each project.
Both cite the source record before the RFP — what is actually different?
The citation and the timing are ties, not the wedge. NationGraph cites public records across every SLED category; Signal cites them too, in construction briefs from board minutes, CIPs, and bonds. The difference is the vertical: Signal models the construction pipeline by trade and geography, and maps the project stakeholder web contractors actually sell into.
How is Signal priced compared to NationGraph?
NationGraph prices on a quote basis for a horizontal SLED platform. Signal publishes region-based territory pricing, so a regional construction firm pays for its own market rather than a national all-category database.
