Amazing milestone from @dubdotco! $10M in partner payouts just 6 months after launch 🚀🔥

[Steven Tey @steventey]

If you had told me when I first started @dubdotco that we would reach $10M in partner payouts in 6 months, I wouldn't have believed you.

Immensely grateful to our customers and partners for all the feedback, trust, and support.

Next stop: $50M payouts 😎

[Hello Patient @HelloPatient]

Big news: Hello Patient has raised a $22.5M Series A led by @scalevp, with participation from all existing investors and new partners @alumniventures & FirstLook Partners.

In just 16 months, we’ve gone from idea to serving 100Ks of patients monthly across urgent care, primary care, mental health, virtual care, medspas, and vet care.

Our mission is to 10x patient access + help providers scale practices without scaling headcount.

Grateful to our investors @8VC, @blingcapital, @maxventuresvc, @flexcapital, and @RemusCapital for doubling down on us.

and wrapping up with Paul Johnson, GP @flexcapital sharing his story and how to make the most of moving to the bay area

[Flex Capital @flexcapital]

Founders, a “standard” clause in your term sheet could quietly strip away your power...

What to do:
🔸Don’t skim the “boring” parts of your term sheet
🔸Ask about voting rights tied to employment
🔸Use free tools like https://t.co/ZgXnwoEF26 to instantly flag hidden clauses

[Auren Hoffman @auren]

Founders: there’s a clause in your term sheet that could silently strip you of your voting rights.
Even if you own a majority of your company.
Even if you’re the one who built it.
And most founders have no idea it’s there.
Let’s break it down 🧵

[Flex Capital @flexcapital]
