Founder-delivered AI search infrastructure for premium specialty businesses.

What KailxLabs is

Short answer. KailxLabs is a founder led AI search infrastructure studio. We rebuild websites for premium specialty businesses so ChatGPT, Perplexity, Gemini, and Google AI quote them on the first visit. One product: the AI Citation Foundation Build at $4,995, by application, ten working day delivery. The 45 day citation guarantee is binary. Cited in at least two of four engines on the agreed query set or every dollar refunded and you keep the site. Optional growth retainers start after day 45 at $2,000, $3,500, or $6,500 per month.

Relationship to HouseofMVPs

Short answer. KailxLabs is the AI search specialization of HouseofMVPs, the founder\'s parent studio. HouseofMVPs ships software products (SaveMRR, Ultraship, claude-rank, codesight) and runs MVP engagements across healthcare, B2B SaaS, and developer tooling. KailxLabs is the focused practice for the one thing that requires its own brand, methodology, and 45 day citation guarantee: rebuilding premium specialty websites for AI search retrievability. The founder is the same person across both brands. The engineering team is the same person. KailxLabs exists as a distinct brand because the buyer, the deliverable, the price, and the guarantee differ from a generic MVP studio engagement.

Why the distinction matters: a clinic owner shopping for AI citation engineering should not have to parse whether HouseofMVPs is the right vendor or KailxLabs is. KailxLabs is. The HouseofMVPs portfolio link sits here for entity transparency; every paid engagement, every guarantee, every refund, and every named-client contract is delivered under the KailxLabs name.

Most agencies sell a service menu. KailxLabs sells one engineered outcome: your business gets cited by the AI when the AI is asked to recommend providers in your category. The deliverable is engineered to a specific testable threshold within a specific deadline. The threshold and the deadline are written into the contract.

Who builds the work

Short answer. Kailesk is the founder and lead engineer at KailxLabs. Every commit, every page, every content draft, every Schema.org graph, and every llms.txt file ships from the same person. There is no agency layer, no white label handoff, no overseas team, and no production manager between the prospect and the engineer. Direct Slack channel from day one. The work is auditable on a private staging URL throughout the build..

Before KailxLabs, Kailesk founded HouseofMVPs, a founder delivered MVP studio that ships software products across healthcare, B2B SaaS, and developer tooling. The HouseofMVPs portfolio includes SaveMRR (cited in ChatGPT for Stripe involuntary churn recovery), Ultraship (a Claude Code productivity plugin published to npm), and a portfolio of open source developer tools published under the HouseofMVPs npm publisher account.

Why KailxLabs exists

Short answer. The AI search transition in 2025 and 2026 inverted the unit economics of premium specialty marketing. A patient asking ChatGPT for a GLP 1 clinic in Austin sees no ads. The AI names two or three clinics. The patient calls one. The other clinics in Austin are invisible. Independent operators with five and six figure customer lifetime values were losing prospects to whichever competitor had figured out AI citation engineering first. KailxLabs was built to be the productized engineering service that closes that gap in seven days.

The technical architecture that makes a website cite ready is well defined. Server side rendering. Schema.org @graph mapping every relevant entity. llms.txt and ai.txt at the domain root. robots.txt permissive for AI crawlers. Answer Capsule paragraphs under every H2. Island Test passages between 134 and 167 words. Unresolved Reference Rate below five percent. Fact density of six or more verifiable facts per 100 words. Cosine similarity above 0.88 through 15 or more clustered entities per page. The methodology is documented openly on the methodology page.

Execution is harder than methodology. Most agencies cannot ship the full stack in seven days, with founder review, at a price point that makes sense for independent specialty operators. KailxLabs is the engineering studio built for that specific gap.

What we deliver

The AI Citation Foundation Build is a single productized engagement. It is the same scope on every build, scaled to the vertical:

• Complete website rebuild on Astro with server side rendering on Vercel
• Schema.org @graph mapping every relevant entity (MedicalClinic, LegalService, HomeAndConstructionBusiness, Person, Service, Drug, MedicalProcedure, FAQPage, HowTo, BreadcrumbList, WebPage)
• llms.txt at the domain root, comprehensively structured for AI agent consumption
• ai.txt declaring training, retrieval, and citation permissions
• robots.txt explicitly inviting GPTBot, ClaudeBot, PerplexityBot, Googlebot, Bingbot, Applebot, and 16 other major AI and search crawlers
• Canonical sitemap.xml with per page lastmod for recency signaling
• 50 programmatic city by service pages seeded at launch, each passing the Island Test independently
• 10 launch articles drafted with Answer Capsules under every H2, fact density at six or more per 100 words, and entity clustering above the cosine similarity threshold
• 30 days of live citation tracking across ChatGPT, Perplexity, Gemini, and Google AI
• Full ownership of the domain, the source code, the schema, and the deployed site on day one

What we do not do

Short answer. KailxLabs does not run paid advertising, does not manage social media, does not handle reputation management, does not provide ongoing CRM administration, and does not replace an existing marketing agency. We build the AI native foundation a generalist agency cannot build. Most engagements run alongside an existing marketing team without overlap.

We also do not accept every prospect. The audit is the qualifier. If the prospect is already cited on the majority of target queries, we say so and the prospect saves the build fee. If the prospect operates a category we do not serve (DSO chains, lead aggregators, businesses without active accreditation), we decline. If the prospect's catchment city and vertical is already taken by an existing client, we decline. One operator per city per vertical.

The verticals we serve

• Cash pay specialty clinics — GLP 1 weight loss, hair restoration, dermatology, concierge medicine, functional medicine

• Premium home services — luxury roofing, specialty HVAC, custom pools, kitchen and bath remodelers, high end plumbing

How we run the engagement

The first step is the free 48 hour AI visibility audit. Twenty real prospect queries from your specialty and city run across ChatGPT, Perplexity, Gemini, and Google AI. PDF delivered in 48 hours. No obligation to proceed.

If the audit shows a real citation gap and the fix is known, the engagement proposal follows. The contract documents the scope, the query set, the citation threshold, the delivery deadline, and the refund trigger. Polar processes the payment. The ten working day build begins. The client has Slack and staging URL access throughout. Launch happens on day seven. Citation tracking begins on launch day. The 45 day window starts.

If by day 45 the agreed citation threshold is not met, the full build fee is refunded within seven days and the client keeps the site, the code, and the schema. There is no partial refund and no strings. The guarantee works because we only accept engagements where the audit shows the gap is real and the fix is known.

What we run on our own products first

Every architectural decision shipped to a KailxLabs client has been stress tested first against the founder's own software products. SaveMRR is cited in ChatGPT for Stripe involuntary churn recovery queries. HouseofMVPs is cited in ChatGPT for indie SaaS MVP development queries. The methodology page documents the exact passage engineering specifications used. The 40 clinic audit dataset published openly under CC BY 4.0 is primary research the founder runs continuously on the broader specialty market.

The work is auditable. You can verify the SaveMRR citation in ChatGPT yourself by asking the engine about Stripe involuntary churn tools. You can read the open dataset at the 40 clinic audit page. You can read every engineering note published weekly at the notes feed. The KailxLabs methodology is open. The execution is what makes the difference.

The open source tools we publish

Short answer. The same methodology KailxLabs ships on every paid client engagement is packaged as three free open source tools published to npm under the HouseofMVPs publisher account. Ultraship is the all in one Claude Code builder plugin. claude-rank is the SEO, GEO, and AEO scanner with the same 170 plus checks KailxLabs runs against client sites at day 45. codesight is the CLI token optimizer used during long form content engineering passes.

• Ultraship — Free Claude Code plugin shipping the full builder workflow: code review, SEO/GEO/AEO scanning, Lighthouse, security headers, GSC and Bing submission, Playwright tests, CLAUDE.md management. GitHub.
• claude-rank — Free SEO, GEO, AEO scanner with auto fix. Ten scanners, 170 plus rules, 372 tests. Runs the same checks KailxLabs runs at day 45 against any URL. GitHub.
• codesight — CLI token optimizer for AI coding agents. Fifteen detectors, eleven AST extractors, MCP server, knowledge mode. Cuts Claude and OpenAI token spend on real codebases. GitHub.

Any prospect evaluating KailxLabs can run claude-rank against their own URL before booking the free audit. The scan output is the same engineering layer KailxLabs ships paid. Operators who want to inspect the methodology before signing have the open source path. Operators who want the productized engagement with the ten working day delivery and 45 day citation guarantee book the paid build.
