Services

End-to-End Software
& Marketing Services

We turn complex growth challenges into production-grade solutions — combining engineering, strategy, and performance marketing under one accountable team.

Custom Software Development

Identify your highest-impact build opportunities and define a scalable, production-ready architecture from day one. Our custom software development process aligns technology with business goals through requirements discovery, technical scoping, and agile delivery to ensure you ship on time, on budget, with full code ownership.

SaaS Product Development

End-to-end SaaS from MVP to market leader. We handle product strategy, UI/UX, backend engineering, and cloud infrastructure — with Product-Led Growth mechanics baked in from sprint one so your software is built to be marketed from the ground up.

Performance Marketing & Paid Media

Data-driven paid media across Google, Meta, LinkedIn, and TikTok. CRO, A/B testing, and full-funnel attribution for B2B software companies — and because we may have built your product, the tracking is always accurate from day one.

AI-Powered SEO & GEO

Traditional SEO meets Generative Engine Optimisation. We ensure your brand ranks on Google and is cited by ChatGPT, Perplexity, and AI Overviews — building organic authority that compounds over time and reduces your paid acquisition dependency.

Marketing Automation & CRM

From HubSpot setup to complex multi-channel automation workflows. We build lead nurturing systems that reduce CAC, maximise LTV, and integrate perfectly with your software — because we understand the codebase they need to connect to.

Cloud-Native Development

Future-proof infrastructure on AWS and Google Cloud. Microservices, serverless, Docker, and Kubernetes — scalable architecture that handles growth without requiring a rebuild. We design for scale before you need it.

Mobile App Development

Native iOS, Android, and cross-platform apps with React Native. From mobile-first MVPs to full app growth hacking and ASO strategies — one team that builds the app and makes it grow in the app stores.

Custom CRM Development

Off-the-shelf CRMs make you adapt to their limitations. We build bespoke CRM systems tailored to your exact sales process, data model, and integrations — so your team works faster and your pipeline data is always accurate.

FAQs

Frequently Asked
Questions

Which service should I start with?

Start with a free 30-minute strategy call. We'll audit your current stack and growth goals, then recommend the highest-impact starting point — whether that's a software build, a paid media audit, or an SEO review. There's no obligation and no sales pitch.

Can I engage Brantum for just one service?

Yes. While our most powerful engagements combine software and marketing, we work with clients on individual services too. Many start with a single service and expand to our full retainer once they see the results.

How do you price your services?

Software projects are fixed-price after a Discovery Sprint. Marketing and SEO retainers are priced monthly. We always provide a detailed, itemised proposal before any work begins — no hidden costs, no surprises.

Do you work with early-stage startups?

Yes. Around 60% of our clients are Seed to Series B startups. Our Growth Sprint is specifically designed for startups who need to build and launch fast without blowing their runway. We scope accurately so you know the cost before committing.
