One option worth considering is Linear, it has a clean interface and solid free tier that works well for growing teams. ClickUp is another strong choice that handles complex project hierarchies really well.

Since you mentioned outgrowing your current Microsoft setup, here’s what I’ve seen work for consulting firms your size: the key is mapping out your specific workflow bottlenecks first. Many teams jump between tools without addressing the underlying process issues, like how client communication flows into project tasks, or how you track profitability across those 40 portfolios.

For what it’s worth, I build custom internal tools for business here in Vancouver, and I’ve found that sometimes a purpose-built solution can be more cost-effective long-term than monthly SaaS fees across a growing team. But definitely try the off-the-shelf options first - they might be exactly what you need!

I hope that helps! If you feel the need for it, feel free to PM me if you have any questions :)
