How Axion built leverage by channeling its investors through one vehicle.

Problem & Solution

Background

Mem0 is building the memory layer for AI — infrastructure that lets agentic applications retain context, learn, and personalize at scale.
Founders Taranjeet Singh and Deshraj Yadav bring deep product and ML infra experience — from scaling Paytm and Khatabook to leading Tesla’s Autopilot AI Platform.
They have already shipped popular AI tools in the past. Taranjeet built the first GPT store and scaled it to a million users. Both built Embedchain, a framework to build AI applications that has achieved 10M+ downloads and eval.ai, a popular open source alternative to Kaggle.
The company raised a $20M Series A led by Basis Set Ventures, with participation from Peak XV Partners, Kindred Ventures, GitHub Fund and Y Combinator.

Also backed by an incredible group of angel investors including Scott Belsky, Dharmesh Shah, and the CEOs of companies that have built core infrastructure at scale — Olivier Pomel (Datadog), Paul Copplestone (Supabase), James Hawkins (PostHog), Thomas Dohmke (ex-GitHub), and Lukas Biewald (Weights & Biases).
The Problem: High-Conviction Supporters, But High-Friction Process
While top institutional funds led Mem0’s Series A, Taranjeet also wanted to include 30+ strategic investors — from billion-dollar startup execs to technical peers and early champions of their vision.

“We had so many people who believed in what we were building,” he said. “But wrangling 30+ direct investors creates the kind of operational drag that doesn't work for us today or in the future when we need them to sign docs.”
Adding a similar number of individual checks in the current round meant repeating the same coordination, compliance, and signature flow in current and future rounds — risking slowing the raise, or worse — forcing the team to exclude valuable supporters.
The Solution: Consolidated Support Without the Chaos

Mem0 used a Roll Up Vehicle to bring in $650k from 30+ angels and operators — all in a single line of their cap table. The RUV launched in under an hour and wrapped up in just weeks.
“Before this, fundraising meant chasing people for paperwork and waiting 72 hours just for a signature,” Taranjeet said. “With the RUV, it was as simple as sending a link to investors.”

Rollups handled everything behind the scenes — from onboarding and accreditation to KYC and wiring — with responsive, high-touch support that adapted to tight timelines and after-hours needs. That left the Mem0 team free to focus on engineering milestones and strategic conversations.

“More than the efficiency, it let us say yes to people who have been part of the journey,” Taranjeet added. “We could bring in the right folks at the right time — without slowing down.”
Looking ahead, Mem0 sees the RUV not just as a time-saver, but as a multiplier. “You get the strategic upside without the admin drag,” Taranjeet said. “That’s a superpower — and we’ll absolutely use it again.”
