Technical CoFounder CTO for Construction Tech Startup

lenzy
Berlin (Co-)Founder Tech Part-time None 10% - 20% Flexible (Office and Remote)
About this position:
We're Benno and Mario, and we're building Lenzy, a mobile-first B2B SaaS platform for construction site documentation. We're looking for a technical co-founder who wants to build something that actually matters.The ProblemConstruction crews waste hours on clunky tools instead of doing real work on site. Only ~5% of construction sites use dedicated management tools. The rest runs on SharePoint folders, email chains, and WhatsApp groups. The few tools that exist are horizontal, legacy, and way too complex for people who work with gloves on.Our SolutionLenzy makes construction site documentation as fast and simple as the work itself. Glove-friendly, offline-capable, radically simple. Few-click daily reports, built-in legal compliance, AI voice-to-text, all in one tool that works the way site managers already think. No training needed, no complexity. Fast enough to use between tasks, smart enough to handle the paperwork behind the scenes.Where We ArePrototype doneFirst five test customers/companies lined upMVP go-live planned for September 2026Bootstrapped since April 2025Our StoryWe met three years ago at a proptech startup. Working in the construction industry, we saw a glaring gap: while software teams run projects with polished toolchains, construction sites still rely on WhatsApp and shared folders. We clicked from day one and have been iterating on this idea ever since. Now we need the missing piece: you.What We OfferEqual equity (33%, 6-month cliff, 4-year vesting)Start ~10h/week, no salary — salary + vesting after MVP go-liveCo-founder-level impact: shape product, architecture, and team from day oneA real problem in a massive, underdigitized marketTwo co-founders who know the industry inside outWho You AreYou really love to code, and have 4+ years industry experienceClaude Code is your lightsaber, not your autopilotStrong technical judgment: pragmatic, structured, opinionated on qualityEntrepreneurial mindset: move without being asked, communicate early, own outcomesBonus: experience building iOS appsThe Team: BerlinBenno (36) · CEO: Architect. 4 years at a top firm, 5 years at a construction tech startup. Knows exactly what's broken in on-site documentation.Mario (33) · CPO: Ex-founder. Business Analyst from the energy sector. Structured thinker with startup DNA.Interested?Write us at cto@lenzy.cc
