What towebu GmbH does

towebu GmbH is a Berlin-based technology consultancy that sells senior engineering judgment to software-building teams. Its service portfolio is structured around fractional CTO/VP Engineering engagements and adjacent offerings — team building and hiring support, architecture and code review, delivery process optimization, hands-on Go/backend development, and technical due diligence for investors and acquirers. The stated buyer personas are founders, CTOs, and engineering leaders at startups and scale-ups who lack full-time executive engineering capacity or who need independent technical assessment. Delivery is described as embedded rather than external, with consultants joining standups, reviewing pull requests, and writing production code alongside client engineers.

The firm's proprietary technical asset is GoLazy, an open-source Go web framework emphasizing convention-over-configuration and developer productivity, which the company lists as used in production across multiple client projects. The supporting technology stack centers on Go, web framework development, and backend systems. The firm also operates a separate product domain, letsvotefast.com, though its scope is not detailed in available sources. Marketing and top-of-funnel demand generation run through an engineering leadership blog (cientifico.net), which publishes content on team design, the team lead role, and organizational trade-offs.

Commercially, towebu operates as a privately held German GmbH with no disclosed external funding, no institutional investors, and a headcount in the 1–10 range. Revenue mechanics are professional services: bespoke, quote-based engagements with no public pricing. The go-to-market motion is sales-led and consultative, initiated through a website contact form and direct email to the founder and Managing Director, Guillermo Alvarez. The firm is registered at Amtsgericht Berlin-Charlottenburg under HRB 220230 B and identifies its operational scope across towebu.com, golazy.dev, and letsvotefast.com.
