Gosu Team's Process
- 💁
Tell us what you need
A 30-minute call to scope the work. No slides, no pitch.
- 🥷🏿
Meet your team
We match you with senior operators from our network. You're working with named people, not subcontractors.
- 🤝
Ship together
Most engagements deliver a working prototype, audit, or roadmap inside two weeks.
Gosu Team Does
Software Development
Get from idea to shipped product without hiring a CTO. We've built MVPs, scaled platforms past 10M users, embedded with engineering teams during hypergrowth, and integrated AI into existing products before it was on every roadmap. B2B SaaS, consumer, enterprise.
Product Management
Stop shipping features users don't want. We'll audit your roadmap, find the three things actually worth building, and run discovery so the next quarter compounds instead of churns.
Marketing
Replace founder-led sales with a system. Our demand gen lead scaled one pipeline from zero to 300k MQLs per month — we'll set up your SEO, paid, and outbound so the leads keep coming whether or not you're on the call.
Operations
Your data is probably a mess. We'll fix the taxonomy, set up the warehouse, wire up Amplitude or your tool of choice, and leave you with dashboards your team actually opens.
Product Design
Your activation rate is a design problem. We'll audit the funnel, redesign the moments that matter, and run user research so you know what to ship before you build it.
Research
Don't spend six months building something nobody buys. We'll run customer interviews, pressure-test the positioning, and tell you whether your idea has a market before you write the first line of code.
