A Cadence and HAH Software defence programme

Prove it in simulation.
Win it in procurement.

Sim2Proof connects defence startups, supply chain companies and primes in one simulation proven ecosystem. Innovators validate their designs virtually and reach qualification faster; primes gain early sight of the technology and partners they will need next.

Who it's for

Built for the companies shaping the next generation of defence capability

Universities

Research groups and spinouts turning academic breakthroughs into defence capability, with a route to industry partners, funding and real programmes.

Defence startups

Early stage companies with breakthrough technology that need to prove performance and credibility before the first major contract.

Supply chain companies

Specialist suppliers ready to move up the chain, strengthen sovereign capability and meet the evidence demands of today's programmes.

Primes and integrators

Join the ecosystem to see emerging technology early and find proven partners, suppliers and acquisition opportunities.

For primes

An ecosystem of proven innovation, ready when you need it

The pace of change in defence means no prime can design and develop everything in house. Sim2Proof gives you a curated community of companies whose technology is already validated in simulation, so when a new requirement lands you have partners to choose from, not a search to start.

Cadence and HAH Software act as trusted advisers, bringing you the right companies at the right time.

Become a prime partner

Early sight of future technology

See emerging capability while it is still being proven, before it reaches the wider market.

A bench of proven suppliers

Draw on companies validated in the same simulation tools your engineering teams already rely on.

Partnership and acquisition pipeline

Identify companies to partner with, invest in or acquire, with engineering evidence already in place.

Trusted advisers

Cadence and HAH Software curate and qualify the ecosystem, saving your teams time and risk.
