Steinlog vs Tendium:
which fits a construction bid team?

Tendium (SE) sells an AI-driven public-sector sales platform under the line "Grow your public sector sales", built around a trial-first funnel with a scripted first session. It publishes a clear price anchor — from €125/month with unlimited users — and reports 1,395+ customers. It advertises payment-data insights for Sweden, Norway and Finland, which may be a meaningful advantage in those markets. We did not find public materials describing construction-specific workflows such as inschrijvingsstaat or RAW/STABU BoQ handling, or addendum diffing mapped into construction bid tasks. As of July 2026, based on public materials.

Side by side

Steinlog vs Tendium, dimension by dimension.

Dimension	Steinlog	Tendium
Core promise	Found → qualified → assembled → ready for submission, one running plan per bid.	Discovery and analysis of public-sector sales opportunities across any industry.
Pricing	Disclosed packaging, no hidden gate.	Public anchor: from €125/month, unlimited users — a strong seat-anxiety killer.
Onboarding	/start: connect a live TenderNed tender and generate an initial bid plan in the product.	Trial-first, with a scripted first session guiding the new user.
Construction-native artifacts	Native inschrijvingsstaat, BoQ, UEA and Nota van Inlichtingen handling.	None described — the platform is horizontal across public-sector categories.
Addendum & clarification tracking	Addenda are diffed against prior versions where available and mapped to affected tasks and draft sections.	Not a named part of the public product story.
Multi-partner bidding	Consortium data rooms — partners see the bid, never each other’s library.	Not addressed in public materials.
Proof	Early-stage pilot program; proof is being built, honestly labeled as such.	Reports 1,395+ customers and advertises payment-data insights for Sweden, Norway and Finland, which may be a meaningful advantage in those markets.
Company stage	New entrant, NL/SE construction focus.	Well-funded (reported at roughly $21.6M raised) and scaled across the Nordics.

Said plainly

What Tendium is good at.

Honest comparisons name the other side's real strengths. Here is where Tendium earns it.

+
A public, unlimited-seat price anchor — "from €125/mo, everyone included" — removes the seat-anxiety objection that most of this category hides behind a sales call.
+
A large, proven customer base (1,395+) and payment-data insights for Sweden, Norway and Finland, which may be a meaningful advantage in those markets.
+
A scripted, trial-first onboarding that gets a new user to a first result quickly.

The trade

Where Steinlog is different.

Not a superset of Tendium — a different shape, built around the full journey from a found tender through to submission readiness.

✓
Construction depth Tendium does not claim to have: inschrijvingsstaat, RAW/STABU bills of quantities, UEA and Nota van Inlichtingen handled natively.
✓
The bid keeps moving after discovery — deadline cascade, addendum diffing and draft assembly, not just an opportunity feed.
✓
Consortium data rooms for multi-partner bids, a case Tendium’s public materials do not address.
✓
Ireland (EU) assistant inference and a per-client EU database, argued at the architecture level.
✓
/start: connect a live TenderNed tender and generate an initial bid plan in the product, in the same spirit as Tendium’s public pricing — transparency without a sales call.
