Case Study: Semoria
From Idea to Production SaaS in 6 Weeks
The Build, in Numbers

The Story
Semoria started life as bespoke tone-of-voice agents for Agenticise clients. Marketing functions across multiple sectors had the same problem: a brand voice they had spent years sharpening, ideas in abundance, and no human capacity to publish consistently in that voice every week. We built custom engines that solved it for one team at a time, including the FPC content engine that took output from 1-2 posts a month to 2+ a week without a hire.
By early 2026 the pattern had repeated so many times across different marketing functions that the bespoke route was clearly not the right shape for most of them. The £8,000 to £20,000 build cost was a stop sign for the teams that needed the methodology most. The right shape was a subscription, on the same underlying engine, with the same human-in-the-loop control.
So in six weeks Agenticise designed, built, and shipped Semoria. A multi-tenant SaaS with payments, auth, AI integrations, security hardening, and a full marketing engine, on a stack that costs under £40 a month to run at 50 paying users. The full origin story is in the first post of the series.
Read Post 1: Why We Built SemoriaThe Build
Six weeks was possible because of multi-agent orchestration in Claude Code, not because one AI worked harder. A lead agent split independent slices of the build across parallel sub-agents running in isolated git worktrees. One would draft a new API route, another would refactor the billing flow, a third would write tests for the voice engine, and a fourth would build a programmatic blog page. The lead reviewed, integrated, and arbitrated conflicts; the human role shifted from writing code to arbitrating scope, judging trade-offs, and owning anything irreversible.
The full methodology, including the lead-agent and sub-agent pattern, what we deferred, when to switch between deep-work and parallel-work modes, and what humans still own, is covered in Post 2.

A lean, modern SaaS stack runs Semoria for around £40 a month at 50 paying users. Every layer is chosen as a utility, not an endorsement. The full architecture, multi-tenant patterns, security hardening, and cost table at 0, 50, 200, and 500 users is in Post 3.
The Marketing Engine
The marketing engine was production-ready on day one, not bolted on after launch. Programmatic blog with FAQ schema and AEO-ready structure, three free tools acting as distinct conversion funnels, persona pages for programmatic SEO, content-calendar driven social automation, and 27 transactional email templates wired into the trial, billing, and digest flows.
| Marketing channel | What we built |
|---|---|
| Programmatic blog | 47 posts at launch, MDX with FAQ frontmatter rendered as JSON-LD FAQPage schema. |
| Free tools | Voice Analyser, Post Generator, Voice Score Card. Each is a contained value unit with its own conversion funnel. |
| Persona landing pages | Programmatic SEO across niche segments with intent-aware copy. |
| Email automation | 27 templates covering trial onboarding, billing events, weekly digest, and feature discovery. |
| Analytics and funnels | PostHog funnels wired from first pageview through trial conversion to billing event. |

Frequently Asked Questions
Six weeks from a standing start to a multi-tenant production SaaS with three paid tiers, a 30-day free trial, three free tools, a programmatic blog, automated email flows, and full analytics. The work covered architecture, authentication, payments, voice fingerprinting, content generation, scheduling, the marketing engine, and security hardening. The full build inventory is 424 TypeScript files, 73 API routes, 64 database migrations, 47 blog posts at launch, 27 transactional email templates, and 5 n8n workflows.
Multi-agent orchestration is the practice of running several AI coding agents in parallel against different parts of the same codebase, with a lead agent coordinating their work. Each agent gets an isolated workspace, a scoped task, and a clear definition of done. The lead splits independent slices across parallel agents, then reviews, integrates, and arbitrates conflicts. The result is real wall-clock compression on multi-feature work without sacrificing review quality.
Two safeguards. First, every parallel agent works in an isolated git worktree so that file edits cannot collide at the filesystem layer. Second, the lead agent scopes tasks so the surface areas do not overlap, which is the same discipline a senior engineer applies when splitting work across a team. When agents do touch shared files (shared types, configuration), the lead serialises those changes and runs them through review before integration.
Next.js on Vercel for the app and hosting, Supabase Postgres for data with row-level security on every table, Supabase Auth for sign in, Stripe for subscription billing, Resend for transactional email, n8n for workflow automation, PostHog for analytics and product funnels, and Sentry for error monitoring. The AI layer uses Claude via OpenRouter for generation, Perplexity Sonar Pro for research grounding, and Anthropic Haiku for the free tools. The lean stack runs comfortably for around £40 a month at 50 paying users, with clear unit economics as the user base grows.
That the agency can deliver whole platforms, not only single-workflow automations. Semoria is a multi-tenant SaaS with payments, auth, security hardening, AI integrations, and a full marketing engine, all designed and built by Agenticise. The same methodology, voice modelling work, and content engine that runs in Semoria every day is what underpins the tone-of-voice work Agenticise delivers for clients. The Semoria build is the proof point for the under-8-weeks idea-to-production claim that anchors the agency offer.
Semoria is a product built and owned by Agenticise. It runs as the productised tone-of-voice content engine for marketing functions that want the methodology without commissioning a custom build, while the agency continues bespoke work for mid-market clients. The two share infrastructure, design language, and a single founder, which is why the build velocity is what it is. Semoria is also the ownership story applied to ourselves: the platform Agenticise built and owns outright, which is the same move we help clients make.
