Most brands pour money into ads, then send every expensive click to a page nobody ever rebuilt. The page between the click and the checkout is the highest-leverage, least-tested asset you own. That's the only thing we work on. WHO WE ARE I'm Jacob Elbaum, founder of Shivook, a conversion-rate-optimization team for DTC and Shopify brands. We build the landing and offer pages your paid traffic should be converting on, prove the lift head to head against your current page on live traffic, and keep testing what wins. You work with me directly; my team handles build and delivery behind me. WHERE WE START One productized, low-risk build, so you see a result before committing to anything bigger. Flagship product: a purpose-built landing/offer page to replace whatever your paid traffic currently lands on. Roughly a two-week build. Broad catalog: the same approach applied to your core product page. Either way, we A/B test the new page against your existing one on your live traffic. The lift is auditable and yours to verify, never platform-reported numbers. THE GUARANTEE A 10% lift in revenue per visitor in a controlled test, or your money back. We carry the risk, not you. PROOF A Shivook-built offer page for Particle for Men replaced the standard product page the brand was sending its Meta listicle traffic to. Same product, same SKU, same traffic source. 12,893 visitors split head to head in VWO. Revenue per visitor: +21.4% at 99.53% confidence Conversion rate: +16.16% at 98.57% confidence Particle made it permanent. It's still running more than a year later. Founder Ayal Ebert: "Jacob built a dedicated offer page to replace what we were sending paid traffic to. It beat our existing path at 99% confidence and it's still running. He comes up with the ideas, builds them, runs them, and shows us what's working. Hands off for us, which is exactly what we needed." Particle isn't a one-off. The same head-to-head approach, new page against the brand's existing page on live paid traffic: Intimate wellness brand: +65% revenue per visitor Eyewear brand: +52% revenue per visitor Antiperspirant brand: +45% revenue per visitor Car care brand: +32% revenue per visitor Electric toothbrush brand: +24% revenue per visitor ONCE IT'S WORKING When the first build proves out, most brands move into an ongoing testing program: a steady cadence of controlled, revenue-reported experiments that compound over time, priced to your store's size. We talk about that on the call once you've seen a result, never before. HOW TO START Post your job or message me. Tell me your store and where your paid traffic lands, and I'll send a short Loom on the single biggest opportunity I see in your funnel before we even get on a call.

Most brands don’t have a product problem. They have an explanation problem. I help founders, agencies, and growing companies turn complex brands, products, and ideas into clear positioning, sharper messaging, and words that give people a reason to care. Top Rated Plus. 100% Job Success. 15+ years of experience. 100+ brands shaped. Ad agency background. Featured in The New York Times, The Wall Street Journal, Adweek, USA Today, Forbes, ESPN, Washington Post. Clients hire me when the product is strong, but the story isn’t landing. The website feels vague. The pitch deck feels flat. The launch needs a stronger hook. The name isn't clicking. The brand sounds too much like everyone else.

My background runs from Hollywood to the White House, with work across advertising, entertainment, startups, SaaS, fintech, CPG, hospitality, nonprofits, sports, and B2B/consumer brands. What I help with: -Positioning and messaging frameworks -Website and landing page copy -Pitch deck and investor narrative -Communication plans -GTM messaging and launch strategy -Naming, taglines, voice, and tone -Campaign concepts and creative direction -PR, content, and founder visibility messaging -Strategic audits and pre-launch reviews Recent work includes: -Website messaging for an enterprise SaaS client that helped 2x conversions -Brand strategy for a fintech platform scaling across four continents -Messaging and verbal identity for a national innovation nonprofit -GTM strategy for a CPG food brand now sold nationwide -Brand identity for an All-Star NBA player -A Gold ADDY-winning renewable B2B energy campaign I’m a good fit when you need senior thinking, clear strategy, and writing that sounds like a human actually wrote it

I'm a furniture designer and 3D visualization specialist based in Istanbul. I run Simula Design Studio, a small design practice focused on furniture and product development, technical drawings, and photorealistic rendering for small brands, makers, and architects. What I can help you with: — Custom furniture design — from concept to production-ready drawings — Photorealistic 3D rendering of furniture and product (3ds Max + Corona) — Interior visualization for residential and contract spaces — Technical 2D drawings and production documentation (Rhino) — Lookbook and catalog imagery for furniture brands How I work: I treat every brief as a design problem, not just a rendering task. Whether you bring me a finished sketch or a vague idea, I'll ask questions early to align on proportion, material, mood, and intent before any model is built. My references sit somewhere between soft minimalism and contemporary craft — clean, material-honest, quietly considered. Who I usually work with: Small to mid-size furniture brands, independent makers, architects, and interior designers who care more about how a piece is made and seen than how loud it is. If your project sits in that world, we'll likely work well together. Feel free to message me before sending a proposal — I'd rather scope the right package together than guess at it.
