Strong by Form

Strong by Form is a materials company founded in Chile in 2018 and headquartered in Madrid, with operations in Santiago and Stuttgart. Its Woodflow-core slab spans 10 metres at around 80% less weight than steel and concrete, placing fibre only where the load needs it and using up to 75% fewer trees than comparable mass timber. In September 2026 it raised €5.8 million as the first tranche of a €10 million Series A led by boisei investments, with the slab at TRL 6 and certification and deployment planned in Spain, France, Germany, and Switzerland within two years.
