Last week I said luck is a number: who you've met, times what you've done about it.
Phone calls make that hard. 20 minutes with someone, and unless you're taking notes the whole time, most of it's gone by the next call.
So: Blinq's AI Notetaker now takes phone calls.
Call someone from Blinq or your own phonebook, and the whole call is summarized and saved to their contact - and synced with your AI tools or CRM if you're connected. Over time you build up history with each person: the first meeting, every spontaneous call in between.
More remembered, more acted on. The math takes care of itself.
A fun way to try it:
1. Download Blinq
1. Go to the AI Notetaker tab
2. Tap the phone icon and verify your number in 30 secs
3. Call +1 (707) 873-7862 for wholesome pep talks recorded by elementary school kids
4. Your first AI call summary will be about believing in yourself
HubSpot has always been a company i've idolized. Not just for their success, but mostly for the way they've inspired and culturally transformed marketing (and now GTM holistically).
They entered an established category and just did EVERYTHING differently.
They created an entire category of "Inbound Marketing".
They absolutely DOMINATED the content and SEO game and became the case study for everyone who followed.
After having already built a successful martech business, they decided to build a fricking CRM and go head to head with Salesforce!
Even the way Dharmesh Shah and Brian Halligan built and led the company was something I've studied and learned from over my career (and now Yamini Rangan has been doing a damn good job with this next chapter).
When I went to my first INBOUND, the vibe was unlike any large-scale tech conference I'd ever been to.
Everything just felt... fresh. Fun. Positive. Inspiring.
So imagine how giddy I was when I got selected to be part of the UNBOUND Content Creator Program for #UNBOUND26! 😁
Can't wait for the first UNBOUND and getting to be a part of it in Boston Sept 16-18 (not gonna lie, wish it was in SF again this year 😆 )
I'll also be doing a 90-min workshop on building your first agent so if you're coming, I promise it'll be a good time all around!
HubSpot Ventures is excited to announce our participation in Bland's Series C, led by Dell Technologies Capital!
Voice is one of the most important interfaces for how mid-market businesses serve their customers, and we're still in the early days of adoption. What sets Bland apart is how they've built their entire stack from the ground up specifically for the kinds of long, complex, high-stakes conversations that matter to businesses in healthcare, financial services, and insurance. Many companies in these industries rely on HubSpot to power front-office tasks such as intake, marketing campaigns, and customer service.
Most voice AI is built on third-party models. Bland builds their own, which gives their customers the security, reliability, and customization that regulated industries require. Today they handle more than 3.5 million calls per week for companies like Samsara, Kin Insurance, and Corgi, and their voice agents connect directly to HubSpot CRM to enable smarter, more context-aware conversations for our joint customers.
We're excited to partner with Isaiah N. Granet, Sobhan Nejad, and the full Bland team and support their growth. Welcome to the portfolio!
Our Managing Director Adam Coccari makes the case for why the era of renting frontier intelligence is ending. Companies running AI at scale will increasingly build and host their own models — post-trained on proprietary data, tuned to their own agent harness, and served at a fraction of the cost. And the infrastructure to do it is already here.
Read the full thesis below. ⤵️
Last week Harvey announced that their agent matched Opus on long-horizon legal work at 11x lower cost. That result should make everyone pause and take notice.
They achieved this by post-training their own model from an open-source base (Kimi 2.6) against their own Legal Agent Benchmark, then ran it as the main worker with Opus acting as an advisor.
This is the shift I'm watching most closely in applied AI. The best AI-native teams running AI products at scale are starting to create and host custom models for their flagship agents. This is the path to long-term differentiation and healthy margins.
The unlock is having enough real product usage at volume, plus detailed agent eval traces, used to post-train an open-source base. A company like HubSpot, with millions of customer interactions across its tools, sits on exactly that.
A growing set of startups now supports each step: companies like Trajectory and Applied Compute across the full process, Fleet AI, Inc. and Deeptune for RL training environments, and Fireworks AI, Baseten, and Modal providing inference and hosting.
It’s time to build (your own model)!
Congrats to our portfolio company GrowthX AI on launching GrowthOS!
GrowthOS gives GTM teams a way to manage website-driven growth without stitching together agencies, tools, and retainers. Expert strategists set the direction and AI agents handle execution helping companies become the answer buyers and AI models reach for. We're optimistic about what this means for marketing leaders navigating how discovery works today!
Proud to be on this journey with Marcel Santilli and the GrowthX AI team.
Today is the biggest day since starting GrowthX AI.
We’re announcing GrowthOS: closed-loop system of growth for content, SEO, AEO, and website operations.
Marketing teams are spread thin and under pressure to grow faster with less.
AI should be the reason you're accelerating. But it's NOT.
Instead they’re drowning in busy work and coordination.
Strategy is in one place.
Briefs and assignments are in Airtable.
Analytics are in GA and Search Console.
SEO data is in another tool.
AEO tracking is bolted on somewhere else.
Docs are full of comments.
The CMS feels like a database with a publish button.
Workflow tools give you 200 blank nodes and bad context.
By the time the work ships, the team has spent more energy moving information between tools than making the work better.
The result is what I call random acts of content.
---
GrowthOS is our answer to that.
It brings five layers into one system:
A system of record for your website, search, and discoverability.
A system of context for your brand, product, audience, and market.
A system of intelligence that shows you what to do next.
A system of action that turns strategy into workflows.
A system of learning that gets smarter from performance data and human input.
This is the codification of everything we’ve learned working with teams like Ramp, Lovable, Vercel, Webflow, SentinelOne, and Reddit.
We built it for marketers who want the leverage of AI without needing to become engineers.
You get a deployed strategist (not fresh out of college 😊)
We set it up with you.
We calibrate it.
We help shape the content strategy.
We configure AI visibility tracking.
We monitor the early signals with you.
Then it’s yours to run. Nothing holding your team back.
The first package is $6,000/mo.
I’ll be personally joining as many demos as I can.
Comment here, DM me, or book time on the website.
This is truly my life’s work.
We’re just getting started. Much love ❤️

Last week, we hosted founders, operators, and investors at Fenway Park alongside our portfolio company Lovable and partners at Silicon Valley Bank. The inaugural #BOSTechWeek brought the city's tech community out in full force, and our event reflected the energy around what's being built in Boston.
Thanks to everyone who made time to join us!
Congrats to Arjun Mahadevan and the doola team on going live across four major AI environments -- Claude, ChatGPT, Replit, and now Lovable (a fellow HubSpot Ventures portfolio company). Founders can form a US LLC in the same chat session where they built their product.

Proud to back Joshua Perk 👻, Nick Masters, and the whole crew at Vector 👻! We couldn't be more excited support them in their Series A here at HubSpot Ventures.
We met Josh and Nick in 2023 through the Drift world when I was pretty new at HubSpot and they were pretty new on an idea. Since then, it has been awesome to watch how thoughtful they are about learning from customers and building a durable platform.
B2B marketing is being reimagined in real time. Everyone has seen the data about cold emailing and cold calling and zero-click SEO. Every motion that used to fill the funnel is decaying and we see a huge opportunity in helping customers optimize (not waste) ad spend.
Vector is built for this moment, serving how marketers actually want to act in 2026. Their traction is the kind you rarely see at this stage, and it's almost entirely inbound and founder-led, which tells you everything you need to know about this dang team!!
Many many thanks to Josh and Nick for trusting us on your journey; as well as our great friends at SignalFire for leading the round and all the support (Varun Ramakrishnan, Wayne Hu, Jim Stoneham) 🧡
See you on the ghost tour!! 👻👻👻
