P4gent
P4gent is your purchasing assistant—an AI agent that tracks your suppliers, monitors your spend, finds alternatives, and drafts communications with the context of each relationship.
The Short Version
Small businesses and individuals spend hours managing suppliers: comparing prices, chasing invoices, finding alternatives when costs rise, and maintaining relationships. P4gent handles the operational overhead of procurement so you can focus on decisions, not administration.
The Problem
Procurement is death by a thousand cuts.
Unless you’re big enough for a procurement team, supplier management falls through the cracks:
- Subscriptions auto-renew at higher rates because nobody checked
- You’re paying more than you need to because comparing alternatives takes time you don’t have
- Supplier relationships go cold because follow-up emails don’t write themselves
- Cost visibility is a spreadsheet you update once a quarter (if that)
- When you need to cut costs, you don’t know where to start
The irony: the information exists—in emails, invoices, bank statements—but synthesising it requires time you’re supposedly saving money to buy.
Our Approach
Your purchasing department, population: one AI.
P4gent connects to your email, accounting software, and bank feeds to build a live picture of your supplier relationships. It doesn’t just track spend—it understands context: who you’ve been with for years, who’s been raising prices, who you’ve been meaning to review.
Relationship-Aware
P4gent knows that your conversation with a supplier you’ve used for 5 years is different from a cold outreach to a new vendor. When it drafts emails, it uses the context you’ve provided plus what it’s learned from your history.
Proactive, Not Reactive
P4gent doesn’t wait for you to ask. It notices when:
- A renewal is coming up and prices have changed
- A supplier you use has a competitor offering better terms
- Your spend in a category has drifted from budget
- An invoice doesn’t match the agreed rate
Human in the Loop
P4gent drafts, you decide. Every email goes through you before sending. Every significant decision surfaces for approval. It’s an assistant, not an autonomous buyer.

Product Features
Spend Dashboard
See your supplier spend across all categories. Track trends over time. Know exactly where your money goes without manually updating spreadsheets.
Supplier Intelligence
For each supplier, P4gent maintains:
- Relationship history: How long, how much, key contacts
- Pricing trends: Are they raising rates? By how much?
- Contract terms: Renewal dates, notice periods, commitments
- Notes: Your context about the relationship
Alternative Finder
When costs rise or contracts renew, P4gent researches alternatives:
- Finds comparable suppliers in your market
- Compares pricing where available
- Flags switching costs and risks
- Drafts outreach emails if you want to explore
Communication Drafts
P4gent drafts supplier emails with context:
- Renewal negotiations: “Based on our 3-year history and current market rates…”
- Invoice queries: “The attached invoice shows £X but our agreed rate is £Y…”
- Relationship maintenance: “It’s been a while since we reviewed our arrangement…”
Every draft goes to you for review. You edit, approve, and send.
Alerts & Reminders
- Renewal coming up in 30 days
- Invoice received that’s higher than expected
- Spend in category X is 20% over last quarter
- Alternative found that could save £Y/month
Who It’s For
Freelancers & Solopreneurs
You’re running everything yourself. P4gent handles the supplier admin so you can focus on the work that pays.
Small Businesses
Big enough to have real supplier complexity, too small for a procurement person. P4gent fills the gap.
Anyone Managing Household Spend
Subscriptions, utilities, insurance, services—P4gent tracks them all and makes sure you’re not overpaying.
Business Model
Pricing
- Personal (£9/mo): Up to 20 suppliers, basic integrations
- Pro (£29/mo): Unlimited suppliers, full integrations, alternative finder
- Business (£79/mo): Multi-user, team inbox, advanced analytics
Pricing Rationale
Competitor benchmark:
| Product | Price | Scope |
|---|---|---|
| Ramp | Free (card interchange) | Corporate card + expense management |
| Brex | Free-£12/user/mo | Corporate financial platform |
| Pleo | £35-89/user/mo | Spend management |
| Payhawk | £50+/user/mo | Corporate cards + AP |
Our positioning:
P4gent is radically cheaper because we don’t provide financial infrastructure—just intelligence on top of what you already have. No corporate cards, no banking, no interchange revenue to subsidize.
Value anchor:
- Personal tier: £9/mo = cost of one forgotten subscription month
- Pro tier: £29/mo = one coffee per week
- Business tier: £79/mo = less than one hour of admin time
- Breakeven: Catch one auto-renewal or find one better deal
Price confidence:
- Personal tier is impulse-purchase territory (£9)
- Pro tier captures serious solopreneurs who want automation
- Business tier addresses small teams without procurement staff
- All tiers have obvious, immediate ROI potential
The Economics
If P4gent saves you one hour per month on supplier admin, it’s paid for itself. If it catches one auto-renewal or finds one better deal, it’s paid for the year.

Primary channel: Consumer ads + word-of-mouth virality
The £20 CAC reflects a low-friction, consumer-native acquisition model:
| Channel | % of Acquisition | Why It Works |
|---|---|---|
| Social ads (Meta/TikTok) | 40% | Visual demos of “AI that saved me £500/month” convert |
| Word-of-mouth | 30% | Freelancers share money-saving tools with peers |
| SME influencers | 20% | Bookkeepers, accountants, business coaches recommend |
| SEO/content | 10% | “How to audit your subscriptions” brings problem-aware traffic |
Why this CAC is achievable:
- Obvious ROI hook: “Cancel one forgotten subscription and it pays for itself”
- Screenshot-worthy moments: Savings alerts are shareable content
- Referral mechanics: Built-in “share to save” incentives
- No-code simplicity: Anyone can connect email and Xero in 5 minutes
Consumer acquisition playbook:
- Hook: “Your AI accountant that actually saves you money”
- Proof: Real savings numbers from real users
- Friction: Free tier lets users see savings before paying
- Viral loop: Share your savings dashboard, get credits
Why 8% churn is acceptable:
Consumer products naturally churn higher. The economics work because:
- CAC is low (£20)
- Payback is instant (under 1 month)
- Some users return when they get new suppliers to manage
- High-value users upgrade to Pro/Business tiers
