Public deals are decided before the tender is published. We exist so you are in the room when that happens.
Tendervane started with a pattern that repeats across the Dutch public sector: a capable IT vendor finds a tender the day it is published, scrambles for four weeks, submits a decent bid, and loses to the supplier who had been talking to the buyer for a year. The tender was not the start of the deal. It was the end of a process the winner attended and the loser never knew about.
The strange part: much of the evidence was public the whole time. Awards identify the buyer and the supplier; many carry the value, the dates or a stated contract term. That makes many renewals estimable months or years ahead, with the gaps shown rather than guessed. Nobody was reading it that way, because reading it that way is a full-time job.
So we made it software. Tendervane reads the official notices, works out when each contract comes back to market, who holds it, who to call, and watches the market daily for the moments that matter: a consultation opening, a tender going live, an extension being exercised. Your team gets the radar, the pipeline and the playbook. The buyer gets a vendor who did their homework a year early.
How we work
Every claim is source-backed
Buyer, supplier, value, dates: facts come from official notices and link to the source. If we cannot back it, we do not show it.
Facts and estimates never blur
A renewal window is our inference, and every screen says so. Presenting a guess as a fact would win a demo and lose your trust, in that order.
No dark patterns
Transparent pricing, no card for the trial, cancel yourself in one click. The product has to be worth keeping, not hard to leave.
EU data, EU infrastructure
The data is European public procurement; the database lives in the EU. See the security page for the full picture.
Who is behind this
Tendervane is built by Ravid Efroni, independent and bootstrapped, working directly with the first customers. No investors to satisfy, no sales team to feed, no pressure to grow past the point of being good. If you email ravid@tendervane.com, the founder answers.
Independence is a feature for you: it means the roadmap follows paying customers, the pricing stays honest, and the product is built to be kept, not to be pitched.
