THE OPPORTUNITY

When Kizuna’s founders started building their platform, they faced a common healthcare startup challenge: speed vs. stability.

Many startups rush to launch with quick fixes, WordPress plugins, or basic frameworks, but the costs pile up fast:

Security breaches leading to compliance issues

The platform crashes under growing traffic

Expensive rewrites that delay growth by months

Kizuna wanted to avoid these traps by building
A platform with strong foundations from day one.

THE SOLUTION

Better Software partnered with Kizuna to balance speed and scalability with an architecture that would support growth without constant firefighting.
