EXCLUSIVE: Letter AI $40M Series B Pitch Deckđ„
From Y Combinator to Battery Ventures leading the series B
đš Letter AI just closed one of the cleanest, strongest Series B rounds of 2026.
$40M Series B⊠four months after its last raise.
What is Letter AI?
Letter AI is building the AI-native operating system for revenue teams.
And this feels generational đ„
Theyâre collapsing the entire bloated GTM stack into one unified system that does content, training, coaching, deal rooms, revenue intelligence, and real-time guidance: all inside the workflow, all powered by AI.
No more digging through Notion.
No more outdated decks and fragmented CRMs.
Letter is becoming the command center that tells reps what to send, how to respond, what to say, and how to close in real time.
This isnât âAI for sales.â This is AI replacing the stack.
And when a 25-person team is already winning global enterprises and raising $40M led by Battery Ventures just months after their last roundâŠ
Thatâs not a feature company. Thatâs infrastructure in the making đ
đą CALLING ALL FOUNDERS đą
Deel is launching The Pitch: a global startup pitch competition, presented by J.P. Morgan.
Up for grabsâŠ
đ° Up to 100 regional winners receive $50,000 in investment
đ Up to 10 global champions win $1M in investment
đ€ Plus access to exclusive startup perks and a global founder community
If youâre building something bold, this is your moment.
Why did Battery Ventures go so all into Letter?
Because this isnât incremental software, itâs a full-stack replacement of a broken category:
Old enablement made teams manage PDFs. Letter rebuilt it AI-first and became the single source of GTM truth.
When customers rip out multiple tools for one platform (and reps say theyâd riot if it disappeared) thatâs infrastructure.
Where Letter Is Now:
25 employees
Customers in 30+ countries.
Global brands like Adobe, Lenovo, Novo Nordisk, and Plaid.
$40M Series B led by Battery Ventures (4 months after Series A).
Small team. Enterprise logos. Fast follow-on capital.
Anyways, so what did I do?
I went straight to Ali Akhtar and convinced him to share their Series B deck, solely so I could break it down and share it with you guys.
And Iâm not exaggerating: this is one of the tightest, hardest Series B decks Iâve seen at this stage. Especially in GTM.
Itâs sharp. Ruthless. Every slide moves the narrative forward.
In essence: theyâre cracked.
If youâre raising right now, you should be studying this.
This is how you pitch infrastructure, not a feature.
