Growth Systems - Rainmaking RMI

De-risk like an Entrepreneur. Scale like an Enterprise.

A new growth system designed to accelerate speed to market and build conviction in your largest capital investments.

For over a decade, corporates have been told that to innovate they need to think like a start-up.

83%

of corporations report adopting lean startup methodology

Successful startups take 7–9 years to scale

But, what nobody mentioned was that lean startups take a long time to grow.

But, corporate leaders have to prove growth in 3 years

For C-suite leaders under time pressure to prove growth, being late is not an option.

Stuck with no other option, corporates make big bets on the back of a strategy deck, without sufficient real-world evidence to prove it will really work in market.

Looking for growth, leaders have to make a choice between two models, neither of which really work.

Insufficient speed

Years of incremental test & learn

The board needs a statement. Competitors are moving. The sector transition doesn't wait. Incremental experimentation was never going to produce growth at the scale the business needs, and every cycle of it buys another year of delay.

“We've been piloting for three years. We still don't have a scaled new business.”

Insufficient evidence

A big bet made on a strategy deck

Acquisitions built on assumptions nobody tested. Joint ventures structured on analysis that never touched a real customer. Platform investments that looked inevitable from the boardroom, and weren't.

“The analysis was thorough. We couldn't have known it would fail.”

At Rainmaking, this is the challenge we exist to solve: How do de-risk like an entrepreneur, but scale like an enterprise?

We use entrepreneurial rigour to accelerate momentum towards, and de-risk the failure of, the big bets that actually move large organisations forward.

Not a choice between experimentation and scale, but a new growth system designed accelerate the speed to and conviction in large capital investments.
