In London's hyper-competitive SaaS arena, having a great product is just the ticket to the game. Winning requires a ruthless, data-driven growth strategy that satisfies demanding customers and even more demanding investors. The path from promising startup to profitable scale-up is littered with companies that failed to master their unit economics.

From Seed Stage to Market Leader
As a specialist SaaS growth consulting partner for London's most ambitious tech companies, Gravitonic architects the capital-efficient growth engine you need to win. We move beyond generic advice to build a bespoke strategy that fixes your leaky bucket, optimises your revenue model, and prepares you for your next funding round.
Are You Burning Cash or Building an Asset?
We work with London-based SaaS founders and leaders who are under intense pressure to perform. The questions that keep you up at night are the ones we solve:
Our Customer Acquisition Cost (CAC) is soaring. How do we scale without breaking the bank?
Our churn rate is killing our growth. How do we improve our Net Revenue Retention (NRR) to impress our board?
Are we leaving money on the table with our current pricing strategy?
Is our product roadmap aligned with what our most profitable customers actually value?
Our London-Focused SaaS Consulting Services
We provide a clear, actionable framework to optimise every stage of your customer lifecycle for the realities of the London market.
1. Product-Market Fit Validation & Expansion
We pressure-test your product against the fierce competition. Through rigorous analysis of your user data and the market landscape, we help you either dominate your core niche or identify lucrative adjacent verticals for expansion, ensuring a capital-efficient path to growth.
2. Investor-Ready Monetization & Pricing Strategy
Your pricing is a direct reflection of your strategy. We analyse your value metrics and customer segments to design and test SaaS pricing models that maximise Monthly Recurring Revenue (MRR), increase Average Revenue Per Account (ARPA), and stand up to the scrutiny of due diligence.
3. User Acquisition & Retention Engine
We help you build a durable growth engine, not just a marketing campaign. We focus on optimising user onboarding to accelerate "time-to-value" and implementing data-driven churn reduction programmes that are critical for achieving best-in-class Net Revenue Retention.
4. The Metrics Your London VCs Demand
You can't optimise what you don't measure correctly. We help you establish a robust analytics framework focused on the metrics that matter: LTV:CAC ratio, Net & Gross Revenue Retention, payback period, and your core North Star Metric.

Frequently Asked Questions (FAQ)
Q: Why hire a London-based SaaS consultant?
A: We have a deep, first-hand understanding of the London tech ecosystem—from the specific expectations of local VCs to the challenges of competing for talent. We provide context and connections that a generic or remote consultant simply cannot.
Q: Our focus is on B2B/FinTech SaaS. Is your expertise relevant?
A: Absolutely. Our methodology is particularly effective for B2B and FinTech SaaS, where complex sales cycles, high LTVs, and the importance of net revenue retention are paramount. We understand the specific challenges of these verticals in the London market.
Q: How quickly can we expect to see results?
A: While long-term strategy is our goal, our initial focus is on identifying "quick wins." Engagements often uncover opportunities in pricing, onboarding, or retention that can positively impact your core metrics within the first quarter.
