Facts about Proof Dept from their own site and LinkedIn · October 7, 2026
How each company describes itself
Proof Dept
Proof Dept calls itself “a strategic brand and marketing studio for AI companies” and says it works exclusively with AI software companies around Series A. It sells three packages: Proof of Concept, a 4-week diagnostic; Proof of Scale, a 3–5 month brand and marketing program; and Proof Positive, an ongoing retainer.
The two founders lead every project and assemble a team of experts for each project. The studio is based in Los Angeles. Clients shown include Loom, ZOE, Lorikeet, and Novo. LinkedIn lists 2–10 employees.
Humbleteam
AI is inside our own process, and it shows in the numbers: our team designs apps and web projects 20–40% faster thanks to AI skills. For clients, we go one step further and set up AI agents in their own design team for handoff, QA, and design-to-code drafts.
The speed reaches users early. An ING Amsterdam MVP went from zero to a tested product in 5 days, and a prototype for an AI text-to-video platform took 15 days. Since 2017, our 49 people in Prague and Dubai have shipped 200+ projects, AI products among them.
Why AI companies pick Humbleteam over Proof Dept
Three reasons that apply when the product, and the marketing site, both have to be right.
AI in our process: 20–40% faster
With AI built into our process, app and web design moves 20–40% faster. A prototype for an AI text-to-video platform took 15 days, and an ING Amsterdam banking MVP went from zero to a tested product in 5 days. An average brief reaches a clickable prototype in 2 weeks, and a project can start next week.
We design the AI product itself
We designed the platform UX of Cluely’s real-time AI meeting assistant, the platform and app for Afternoon’s AI-first finance model, and the brand for Qantev’s AI health insurance platform. Our AI agents also run inside client design teams, in their own accounts, with human review on every output, and they stay after we leave.
A bench of senior designers
Humbleteam is 49 people, and the senior designers on a project average 9 years of experience. You meet them on the first call, and they do the work. The team has shipped 200+ projects and won 80+ design awards since 2017. Our Clutch score is 4.9 from 35 client reviews.

When Proof Dept is the better call
Two situations where Proof Dept is the stronger fit.
A marketing engine after Series A
Proof Dept builds positioning, messaging, websites, and campaigns aimed at pipeline for AI software companies that just raised. If marketing-led growth is the main goal, their program is designed for it.
A published price before the call
Their site lists prices: $25,000 for the 4-week diagnostic and $75,000 to $300,000 for the full program. A buyer who needs a public number before the first meeting gets one there.

Questions?
Is Humbleteam a good alternative to Proof Dept?
Yes, if your AI company needs the product designed as well as the brand. We designed platform UX for Cluely’s AI meeting assistant and the platform and app for Afternoon, and AI makes our app and web design 20–40% faster. Proof Dept focuses on positioning, brand, websites, and marketing for AI software companies around Series A.
Humbleteam or Proof Dept: who delivers faster?
For a first tested product, Humbleteam: our ING Amsterdam team went from zero to a tested MVP in 5 days, and an average brief reaches a clickable prototype in 2 weeks. Proof Dept publishes a 4-week diagnostic and a 3–5 month full program for brand and marketing, which is a different scope from product design.
Which is better for an AI product’s UX?
Humbleteam, because product UX/UI for AI tools is core work for us, from Cluely’s real-time meeting assistant to Afternoon’s AI-first finance app. We also install AI agents inside client design teams, with human review before anything ships. Proof Dept’s published packages cover a diagnostic, positioning, marketing strategy, brand identity, a website, and campaigns.
How big is each team, and who does the work?
Humbleteam has 49 people in Prague and Dubai, and the senior designers on a project average 9 years of experience and do the work. Proof Dept’s two founders lead each project and bring in designers, writers, developers, and animators as needed, with a team distributed across the US and Europe. LinkedIn lists 2–10 employees.
How much does each cost, and how soon can we start?
Proof Dept publishes prices: $25,000 for its 4-week diagnostic, $75,000 to $300,000 for the full program, and $5,000 to $25,000 a month after launch. Humbleteam publishes no price list; it offers a fixed-price audit, a scoped implementation, or a monthly retainer, and estimates on the first call. Our reply to an AI founder comes within 24 hours, and work can start next week.
