What’s In It

for You.

Build With a

Real Partner

We don’t throw money and walk away. We roll up our sleeves. We’ve scaled startups from 0 to Series A.

Partnership,

Not a Takeover

We invest for equity, far less than a VC would take, so you keep more control while we help you execute, scale, and position for Series A.

Move Fast.

Ship Smarter.

In-house design, engineering, product, and growth. All at your fingertips. Not theory. Not consultants. Actual execution.

From Chaos

to Clarity

We help you cut through noise, align your team, define the roadmap, and move with speed.

Not for Everyone.

"SIROC felt more like a co-founder than an investor. After losing my CTO, they stepped in with both funding and hands-on support. Helping rebuild the tech side and recruit top talent. ProfitTree wouldn’t be where it is without them."

Hannah Gardner

Founder, ProfitTree

"The SIROC team blew us away. Not just smart and efficient, they actually helped us build something far beyond what we thought possible. It’s rare to find a partner who moves this fast and still deeply cares about the outcome."

Matteo Lombardi

Founder, Ultimate Beauty
