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.
