Stop paying for HubSpot and Salesforce. Get your own custom business software that does exactly what you want.
I'm Carlos Real. I build and sell AI systems: voice agents, custom business software, and the go-to-market strategy to put them in front of buyers. Before AI came along, I spent 12+ years in web development and later direct response marketing and sales, running large global budgets across Google, Meta and YouTube.
Approved under Anthropic's Cyber Verification Program for dual-use security work: penetration testing, red teaming and bug bounty research.
You're not buying software because it has AI in it.
You're buying it because the pipeline is leaking, the team is drowning in admin, or the numbers live in six places. AI is one of the tools I use to fix that. Sometimes it's the whole answer, more often it's a small part of it.
AI has moved the build-versus-buy line. Work that justified a SaaS subscription two years ago is now cheaper to build and own outright, and most companies haven't repriced that decision yet. Most AI projects also fail on deployment, not capability, which is a commercial and operational problem long before it's a technical one.
Imagine your entire business in one place.
Every part of the business in one system, built for how you actually work, instead of a dozen subscriptions bolted together, each holding a piece of your data and none of them talking properly to the others.
The capital cost is far lower than you'd expect. AI does a serious share of the development work, which is what has changed the economics. At the end of it you own the software outright rather than renting it forever.
Bespoke business control software
One system that runs the company, built around how you already work. Not an off-the-shelf platform your team has to bend itself to fit, and not five tools stitched together with exports. The one I care most about.
AI voice agents
Answering and following up on enquiries around the clock, capturing lost revenue before it goes cold. Running in production today, built from the ground up rather than layered on someone else's stack.
CRM and prospecting systems
Built around your pipeline and your stages, not a vendor's idea of them. Sourcing, enrichment and outreach that feeds the sales floor.
Go-to-market
Deployment planning, direct response campaigns, and unit economics: lower CAC, higher LTV.
Grew TotalLawn to roughly 50,000 customers and £2m in sales in 18 months, including a B&Q listing and 250+ press features.
Built and scaled the largest domestic heating lead generation site in Scotland, later sold.
Pioneered B2C lead generation across law firms, accountants, insurers and medical practices, driving millions in additional revenue for clients.
Chartered Institute of Marketing (MCIM) and Google Ads certified.
Fact-find call
What the business actually does, where enquiries and revenue leak, what already exists.
Scope and quote
A defined build with a fixed price, not an open-ended retainer.
Two weeks to v1
Two weeks on average to a shipped, production-grade first version. Then we iterate on real usage.
Why build custom software instead of buying HubSpot or Salesforce?
Because AI has moved the build-versus-buy line. Work that justified a SaaS subscription two years ago is now cheaper to build and own outright, and most companies haven't repriced that decision yet.
What does "one system" actually replace?
Whatever your business actually runs on. The shape follows the work, not a template. If you run delivery vehicles, it can include dispatch, route planning and vehicle tracking. If you are online-only, it can be full client management and record keeping. For a medical or therapy practice, it can hold treatment notes, consent and recall. For most businesses it covers the common ground first, CRM, accounting, HR, payroll, ecommerce, customer service, admin, operations and delivery, then adds the parts only your business needs. That is the difference between software built for you and a platform you bend yourself to fit.
How long does a first version take?
Two weeks on average to a shipped, production-grade first version. Then we iterate on real usage.
What does it cost?
A defined build with a fixed price, not an open-ended retainer. The capital cost is far lower than you'd expect, because AI does a serious share of the development work.
Do I own the software at the end?
Yes, outright, rather than renting it forever.
My AI project is stuck between demo and production. Can you help?
That is the common case. Most AI projects fail on deployment, not capability, which is a commercial and operational problem long before it's a technical one.
