From partner teams
// How we work
A compact operating system for growth.
No 40-page deliverables. We audit the full funnel, pick the 20% of work that drives 80% of the outcome, and ship weekly.
01 / Diagnose
Funnel & data audit
Two-week deep-dive across acquisition, activation, monetization and data. Output: one prioritized growth thesis.
02 / Architect
90-day roadmap
A weekly-shipping plan with explicit owners, experiments, ICE scores and success metrics wired into your BI.
03 / Execute
Weekly shipping cadence
We embed with your team, ship in your tools, and review numbers every Monday. No retainers without throughput.
04 / Compound
Systems, not stunts
Hand-off of playbooks, dashboards and hiring plan so growth survives after we leave — or we stay as fractional leadership.
// FAQ
Practical questions, direct answers.
Who do you typically work with?
Seed to Series B SaaS, fintech and consumer brands doing $0.5M–$50M ARR. Founders who want a senior operator embedded in the team, not a 12-slide strategy deck.
What does engagement look like?
Standard engagement is a 2-week audit + 90-day execution sprint with weekly shipping reviews. After that we either exit with a playbook, or stay on as fractional CMO / Head of Growth.
How is pricing structured?
Fixed-fee audit, then a monthly retainer tied to the 90-day roadmap. For qualifying companies we accept a hybrid fee + performance model on clearly-measurable outcomes.
Do you work with existing in-house teams?
Yes — most of our work augments in-house teams. We bring senior thinking, specialist execution, and the operating cadence your team may be missing.
Where are you based?
Nensis, UAB is registered in Vilnius, Lithuania (EU). We operate remotely across European and US time zones.
Let's see if we are a fit.
A 30-minute call. Bring your top growth bottleneck — we'll leave you with at least one intervention worth shipping next week, regardless of whether we work together.
