IdeaStack·Issue, every Thursday·
UK business ideas, backed by real data.
Every Thursday, one deeply analysed UK business opportunity: keyword volumes, competitor intel, SERP data, build plan. Research, not a listicle.
Most “business ideas” articles give you fifty vague suggestions and zero data. IdeaStack goes deep on one UK opportunity, every Thursday, with the keyword volumes, competitor funding and SERP difficulty to act on it.

Audit UK sites for DMCCA fake-review and drip-pricing breaches
Find the breaches, get the policy, for £39 a month
A self-serve tool that crawls a UK business's website, flags banned practices under the Digital Markets, Competition and Consumers Act 2024 (unmarked incentivised reviews, suppressed negative reviews, misleading star-rating aggregation, and drip pricing where mandatory fees appear late at checkout), then auto-generates the written review-management policy the law now requires every trader to hold. It is built for the long tail of UK ecommerce and hospitality SMEs who cannot afford a £15k+ compliance consultancy but now sit under the same enforcement regime as the brands the CMA is already investigating. The timing is the whole story: the regime went live on 6 April 2025, the CMA found over half of 100+ businesses it reviewed could be failing to comply, and on 27 March 2026 it opened five named investigations.

Builder prompts (Pro)

Who reads it
Built for builders, not browsers.
The weekend builder
Day job, side-project itch. Wants a validated idea and a clear plan, not another rabbit hole of Googling. Thursday report, Saturday build.
The serial tester
Launches fast and kills faster. Needs a pipeline of scored opportunities so they can pick the best one and move.
The UK entrepreneur
Tired of US-centric advice. Wants UK search data, UK competitors, UK regulations, UK revenue models. Nobody else does that.
UK-coded
Every other newsletter thinks in dollars. We think in pounds.
IdeaStack is built from UK search data, UK competitor landscapes, and UK market dynamics. “Popular in San Francisco” does not mean profitable in Sheffield.
Field notes
From the blog
Error tracking for your live v1 (UK SaaS, Claude Code 2026)
Your v1 is live, three founding members are using it, and the next outage is a question of when, not if. This is the right-sized observability layer for a brand-new UK SaaS: the three things actually worth watching, how to wire error tracking and a money-path alarm into a Next.js app with Claude Code in one session, source maps so a stack trace points at real code, a simple uptime ping, and the discipline to stop there instead of building enterprise monitoring for three customers.
Your first feature build session after launch (UK SaaS, Claude Code 2026)
Your v1 is live and three founding members are using it. The feedback is rolling in faster than you can build. This is the UK indie hacker guide to your first feature build session after launch: how to read founding feedback for the one signal that matters, pick the single feature that removes the most friction, scope it to one Claude Code session, build and test it against the money path, and ship it the same day with a 'you asked for this' note that turns a paying founder into an evangelist.
Ship your v1 to founding members (UK SaaS, Claude Code 2026)
Scaffold done, auth and billing wired. Now you ship the v1 to the founding members who already paid. This is the UK indie hacker go-live checklist: the pre-launch checks that stop launch day going sideways, how to onboard three pre-paid founders by hand, the feedback loop that tells you what to build next, and the first iteration cadence that turns a founding cohort into retained, paying customers instead of three refunds.
Supabase auth + Stripe billing for a UK SaaS (Claude Code, 2026)
Your skeleton is live. Now your founding members need two things: a way to log in and a way to keep paying you. This is the UK indie hacker walkthrough for wiring Supabase auth and Stripe subscriptions with Claude Code - the auth flow, the subscription model, the one webhook that actually matters, and the UK-specific decision every US tutorial skips: do you take payments through Stripe directly and own your VAT, or go through a Merchant of Record like Paddle and hand the VAT headache away?
Scaffold your validated v1 with Claude Code (UK, 2026)
You did the hard part. You ran the smoke test, made the Mom Test calls, and three founding members have already paid. Now you have to build the thing. This is the UK indie hacker walkthrough for turning a validated idea into a working app skeleton in a single Claude Code session: the PRD that anchors every decision, the CLAUDE.md that keeps the agent honest, plan mode before any code, the first five files, and why you deploy to Vercel on day one before you have a single feature.
Founding-member onboarding after the pre-sale - the UK SaaS playbook (2026)
Three Stripe receipts hit the inbox. Now what? Most UK indie hackers blow the handover - either over-promising delivery dates or going dark for six weeks while they build. Founding members convert at around 70 per cent to paid renewal when handled well; cold leads do not. This is the concierge onboarding kit: the 24-hour reply, the 15-minute kick-off call, the weekly Friday Loom cadence, the private channel, and the launch-flip that turns three pre-sales into three evangelists and the foundation of months 3 to 12 cashflow.

Questions
Frequently asked
What is IdeaStack?
A free weekly newsletter for UK entrepreneurs. Every Thursday we publish one deeply researched business opportunity backed by real keyword volumes, competitor funding data, SERP difficulty scores, and builder prompts.
How is this different from a listicle blog?
Most business idea articles give you a list of 50 vague suggestions with no data. IdeaStack goes deep on one opportunity per week. Live UK search volumes, every competitor and their funding, SERP difficulty, a step-by-step execution plan. Research, not a list.
Are the ideas UK-specific?
Yes, entirely. UK search data, UK-based competitors, UK regulations, GBP pricing. Built because every other tool in this space is US-centric.
Is IdeaStack free?
The weekly newsletter is free forever. The Pro tier (£12/mo) unlocks full reports with keyword tables, competitor intel, SERP analysis, and builder prompts.
I am not technical, can I still use this?
Absolutely. The reports are business analysis, not code. The builder prompts are designed for AI tools like Cursor, Bolt, Claude Code, and Lovable. No coding experience required.
How often do you publish?
One report every Thursday at 6pm. Timed so you can research Thursday evening and start building over the weekend.
