Qu'est-ce que le/la Runway ?

Le runway est le nombre de mois durant lesquels une entreprise peut continuer à fonctionner au burn rate actuel avant épuisement de sa trésorerie.

Runway is the single most important number on the wall of a venture-backed company. Below ~12 months, founders should already be fundraising; below ~6 months, options narrow rapidly.

Lengthening runway means either raising capital (equity, venture debt) or cutting burn (layoffs, paused projects, renegotiated contracts). The best runway extension is profitable growth — every franc of revenue both extends runway and de-risks the business.

Formule
Runway (months) = Cash on Hand ÷ Monthly Net Burn
Exemple

A startup holds CHF 3m in cash and burns CHF 250k per month — runway is 12 months, the point at which fundraising or break-even must be achieved.
