Testimonials
What founders say
“We expected a marketing site. We got a conversion engine. Spend went up, CPL went down — that almost never happens at the same time.”
“We told investors to just look at the site. It did the talking. That's the highest compliment I can pay a launch page.”
Frequently asked
Common questions from New York founders
Yes. We work async-first with founders across the US, including New York. Most of our US clients never meet us in person and have a seamless experience from brief to handoff. All review cycles happen over video call, Loom, or Slack — whichever fits your workflow. We adapt to EST, PST, and CST hours without friction.
We typically start within one week of the brief being signed off. We keep a limited number of active projects so that every client gets focused, senior attention — not a handoff to a junior team. If your timeline is urgent, tell us in the inquiry and we'll let you know our earliest available slot.
Our work is benchmarked against the best coming out of San Francisco, London, and New York. We've built for pre-seed founders, Series A teams, and AI startups competing globally. The output is custom-coded Next.js — not a template — with real Lighthouse scores, real animations, and a design system your team can actually use. See our case studies for proof.
Websites start at $4,000 for a focused marketing site and run to $20,000 for a full site with a CMS, blog, and motion. Web apps and iOS/Android builds run $20,000 to $60,000. AI automation starts at $3,000; a custom AI agent starts at $6,000 plus $400–$1,200 a month to run. SEO retainers are $2,500–$7,500 a month and social is $1,500–$5,000, both with a three-month minimum. Everything is invoiced in USD and itemised in a fixed-cost proposal after the briefing call.
