The 7 Key Metrics You Need to Scale Sustainably and Attract Investors
If you're a founder or CEO looking to scale your business or raise funding, there's one thing that separates those who grow with intention from those who grow on hope: knowing your numbers.
At OSER, we work with startups and scaleups to build brand and growth strategies that are rooted in clarity — creative, yes, but always data-informed.
Here are the 7 key metrics you need to monitor, understand, and improve to scale sustainably and attract investor interest.
1. Revenue Growth Rate
This one’s simple — and powerful. Investors want to see that your revenue isn’t just ticking upwards, but doing so consistently.
Look at:
- Month-on-month (MoM) growth for early-stage
- Year-on-year (YoY) growth for more established businesses
- Your growth rate gives a direct signal of traction and momentum.
2. Customer Acquisition Cost (CAC)
How much are you spending to acquire each new customer? This number reflects the efficiency of your sales and marketing engine.
A sustainable business model means you’re not burning through capital to win customers — you're acquiring them smartly and affordably.
3. Customer Lifetime Value (LTV)
How much value does each customer generate over their entire journey with you? The higher your LTV, the more viable and scalable your business becomes.
It also signals strong product-market fit and the ability to build long-term loyalty — which investors love.
4. Burn Rate & Runway
Your burn rate is the pace at which you’re spending money. Your runway is how long you have left at that pace before the money runs out.
Both metrics help investors (and you) assess how responsibly you’re managing capital — and how urgently you need your next raise.
5. CAC : LTV Ratio
This ratio is your efficiency sweet spot. Ideally, your LTV should be at least 3x your CAC.
If you're spending £100 to acquire a customer who’ll bring in £300+ over time? That’s a green light for growth.
6. Retention & Churn Rates
Growth is meaningless if customers don’t stick around.
High retention (and low churn) indicates a product people love, and a brand that keeps them coming back — both of which are essential for long-term scale and repeat revenue.
7. Conversion Rates
From landing page views to trial sign-ups to paying customers, your funnel performance matters.
Conversion rates show how well your marketing, product, and sales efforts are working together. Small improvements here can have massive effects on revenue and CAC.
Make These Metrics Work for You
The businesses that scale with confidence — and raise investment successfully — are the ones that know their numbers, act on their insights, and communicate them clearly.
