Steinlog vs Tenderwolf:
which fits a construction bid team?

Tenderwolf (BE) sells tender discovery plus a GO/NO-GO qualification triad — "Mogen we? Kunnen we? Willen we?" — with a genuinely self-serve, card-free free tier and radically public €0/79/149 pricing. It has a real logo bar and a reported 1,500+ users, but no published case studies. TenderWolf's public positioning is strongest around discovery, qualification, alerts, and analysis; we did not find public materials showing full bid assembly through submission. As of July 2026, based on public materials.

Side by side

Steinlog vs Tenderwolf, dimension by dimension.

Dimension	Steinlog	Tenderwolf
Core promise	Found → qualified → assembled → ready for submission, one running plan per bid.	Tender discovery plus a GO/NO-GO qualification decision.
Pricing	Disclosed packaging, no hidden gate.	Radically public: €0 / €79 / €149 per month — the most transparent pricing in the category.
Onboarding	/start: connect a live TenderNed tender and generate an initial bid plan in the product.	Self-serve free tier, no card required — an easy first step.
Construction-native artifacts	Native inschrijvingsstaat, BoQ, UEA and Nota van Inlichtingen handling.	Partial construction signal (BESIX appears in its logo bar); no bid-assembly artifacts described.
After the GO decision	Deadline cascade, addendum diffing, requirement checklist and draft assembly all continue past qualification.	TenderWolf's public positioning is strongest around discovery, qualification, alerts, and analysis; we did not find public materials showing full bid assembly through submission.
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.	A logo bar and a reported 1,500+ users, but no published case studies.
Company stage	New entrant, NL/SE construction focus.	Established self-serve player at the low end of the category (BE).

Said plainly

What Tenderwolf is good at.

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

+
The most transparent pricing page in the whole category — €0/79/149 with no sales call required to see a number.
+
The GO/NO-GO triad ("Mogen we? Kunnen we? Willen we?") is a genuinely clear framing for the qualification decision.
+
A card-free free tier removes all friction from a first look, and 1,500+ users suggests that works.

The trade

Where Steinlog is different.

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

✓
The bid does not end at GO/NO-GO — deadline tracking, addendum diffing, requirement completeness checks and draft assembly all continue through to submission readiness.
✓
Construction-native artifacts (inschrijvingsstaat, BoQ, UEA, Nota van Inlichtingen) that a discovery-and-qualification tool does not need to handle.
✓
Consortium data rooms for multi-partner bids, a case Tenderwolf’s public materials do not address.
✓
Ireland (EU) assistant inference and a per-client EU database, argued at the architecture level.
✓
/start connects a live TenderNed tender immediately, the same accessible first step Tenderwolf’s free tier offers — carried through to submission readiness.
