Sullivan Collective for ambitious tech companies.

Tech businesses move fast. Markets shift, products scale, teams double in size, and priorities pull in every direction. At some point, what got you here starts to strain – and that’s where we come in.

At Sullivan Collective, we work with tech founders and leadership teams to bring support, structure, and clarity to high-growth environments. Whether you’re scaling headcount, launching new markets, or gearing up for investment, we help you align strategy, operations and leadership around what actually matters.

We’ve been inside it – at scale. Our founder, Brooke Sullivan, drove strategy and operations during the hyper-growth phase at TikTok ANZ. We understand the pace, the ambiguity, and the pressure – and we bring the experience and perspective to help you move through it with intention.

Tailored for the tech reality

• We understand fast funding cycles, lean teams and evolving business models.
• We help align growth to operations – so scale doesn’t mean stretch.
• We’re independent and agenda-free – your partner, not your investor prep team.
• We work fast, flexibly, and leader-to-leader.
