Wilmington, DelawareCommunication SoftwarePrivate

Rocket.Chat powers secure, self-hosted communication for enterprises, government agencies, and critical infrastructure teams worldwide.

Founded in 2015 by Gabriel Engel, Rocket.Chat has spent a decade building something Slack doesn’t offer: full control. The platform is open-source, self-hostable, and built around data sovereignty. That’s a real differentiator for governments, defense contractors, and enterprises that can’t route internal communications through a US commercial cloud.

The company’s recent positioning under the “Secure CommsOS” brand targets exactly those high-stakes environments: intelligence agencies, critical infrastructure operators, and government departments that need messaging, video, and file-sharing under one roof without handing data to a third party.

Its clients include Intel, Samsung, Nokia, and CAIXA. In March 2026, Rocket.Chat joined the Intelligence Community Marketplace (ICMP) — a meaningful milestone for a company with under 200 employees. The developer community around it (1,000+ active contributors) does a lot of the heavy lifting that normally requires a much larger headcount.

Competing against Slack, Mattermost, and Discord with $37M in total funding sounds like a tough fight. But Rocket.Chat is fishing in a different pond. Regulated industries don’t want Slack. They want something they can audit, air-gap, and own. That’s the market Rocket.Chat is building toward.

Herndon, VirginiaIT Services & ConsultingPrivate

avertra’s MiCustomer DXP helps utilities and energy companies reduce billing friction and recover blocked revenue through digital self-service.

Avertra has been around since 2007, though most people outside the utilities sector haven’t heard of it. That’s fine — their clients have. The company builds digital experience platforms for industries that move slowly: utilities, energy, banking, logistics.

Their flagship product, MiCustomer DXP, is a digital experience platform that sits across 3 pillars: customers, employees, and the organization itself. The goal is to reduce phone calls, automate repetitive tasks, and give people a self-service option that actually works.

One case study tells the story well. A utility company had $8M in blocked revenue and $16M in unbilled revenue it couldn’t collect. Avertra’s platform helped close that gap. That’s the concrete, unglamorous problem-solving that enterprise software is supposed to do but often doesn’t. IBM partnerships have extended Avertra’s reach into enterprise digital transformation projects across North America.

San Francisco, CaliforniaAI Retail TechnologyPrivate

Zippin’s multi-modal AI — overhead cameras combined with smart shelf sensors — enables frictionless checkout across stadiums, airports, and retail stores on 4 continents.

Walk in, grab what you want, walk out. No cashier, no self-checkout kiosk, no scan-and-go friction. That’s the premise behind Zippin, and they’ve been making it real since 2018.

The tech stack is multi-modal: overhead cameras plus smart shelf sensors. Not just cameras alone (which struggle with small or unbranded items), not just weight sensors alone (which struggle with density). The combination is what lets Zippin claim accuracy above 99.9% in high-traffic venues like stadiums and airports.

Their deployment list includes Aramark, Compass Group, LEGOLAND Windsor, Dublin Airport, and sports stadiums across 4 continents. In 2024, they launched in Puerto Rico through a partnership with MGI Caribe and opened in the Southern Hemisphere’s largest stadium. The CEO, Krishna Motukuri, came out of Amazon — that origin shows in the operational details. The Zippin Cube system can retrofit an existing store in a single day with minimal downtime.

New York City, New YorkEngineering Design SoftwarePrivate

nTop’s implicit modeling approach allows aerospace and defense engineers to design complex geometries — lattice structures, heat exchangers, topology-optimized parts — that traditional CAD simply can’t handle.

Traditional CAD breaks when you push it. Complex geometries, topology optimization, lattice structures for 3D printing — the tools most engineers use were built for a different era. nTop, founded in 2015 by Bradley Rothenberg and Scott Diaz, is building the replacement.

The core differentiator is implicit modeling — a mathematical approach to geometry that doesn’t fail the way traditional boundary-representation CAD does in complex shapes. When Lockheed Martin wants to parameterize heat exchanger designs or Siemens Energy needs to iterate turbomachinery parts, they reach for nTop.

In February 2025, nTop acquired cloudfluid, a German company specializing in computational fluid dynamics software. The integration means engineers can now run CFD simulations in near real-time inside the same design loop — no separate meshing step, no multi-week simulation queues. NVIDIA has backed the company through NVentures and built integrations with nTop’s platform, tying computational design directly to GPU-accelerated computing.

Austin, TexasIT Community & MarketplaceAcquired by Ziff Davis (2019)

Spiceworks serves over 6 million IT professionals with free help desk, network monitoring, and inventory tools — monetized through a marketplace of 3,000+ technology vendors.

Started in 2006 by 4 ex-Motive executives — Scott Abel, Jay Hallberg, Greg Kattawar, and Francis Sullivan — Spiceworks figured out something early that took the rest of tech years to catch up on: build a free tool, build a community, build a business around the attention.

The model is simple: give IT pros free tools (help desk, inventory, network monitoring), then sell access to those IT pros to technology vendors who want to reach buyers at the moment they’re researching products. Over 6 million IT professionals and 3,000 vendors make it one of the most valuable B2B intent networks in the industry.

Ziff Davis acquired Spiceworks in 2019, and the company now operates as Spiceworks Ziff Davis (SWZD). The annual SpiceWorld conference in Austin has become one of the IT industry’s signature events. The 13th Annual State of IT report, published in partnership with Aberdeen Strategy & Research, carries genuine weight in enterprise IT planning conversations.

San Ramon, CaliforniaIT Services & Business ConsultingPrivate

TESCRA delivers SAP-centered enterprise IT consulting across energy, banking, telecom, and manufacturing — serving Fortune 1000 clients from delivery centers across 6 countries.

Incorporated in 2002 and headquartered in San Ramon, California, TESCRA has built a niche in the overlap between enterprise consulting and global delivery. Their model: deep SAP expertise, cross-industry implementation experience, and a delivery structure spanning the US, Canada, UK, Germany, Bulgaria, and India.

Their client list runs through serious enterprise names — TESCO, GE, PepsiCo, Vodafone, Citigroup. The industries they serve (energy, banking, telecom, retail, manufacturing, healthcare) all share a common trait: heavy dependence on ERP systems and legacy application integration. That’s TESCRA’s core competency, and it’s not easy to replicate.

The company has appeared on Inc. Magazine’s America’s 5000 Fastest-Growing Companies list and earned recognition among the top 100 minority and women-owned businesses in the US. 85% of Glassdoor reviewers say they’d recommend the company to a friend — a real signal for a 192-person firm competing against much larger players.

Washington, D.C.Customer Success PlatformPrivate

ChurnZero’s platform builds real-time health scores on every customer account — tracking product usage, engagement, and feature adoption so CS teams can act before accounts go dark.

The problem ChurnZero solves isn’t complicated to understand but is hard to fix: subscription businesses don’t know their customers are about to leave until they’ve already left. ChurnZero gives customer success teams the signals to act before that happens.

The platform tracks product usage, feature adoption, and engagement to build health scores on each customer account. Declining logins, reduced seat usage, changes in engagement patterns — ChurnZero surfaces these as signals and automates the playbooks to address them.

In October 2025, the company announced a suite of autonomous AI Agents that execute on risk and opportunity signals around the clock. One public result: YuLife, serving 1,200+ organizations, achieved 98% customer retention — 20 points above industry average — by automating renewal workflows through the platform. ISO 27001 certified in 2024, SOC 2 Type II completed in 2025.

Mountain View, CaliforniaMobile Security & UEMAcquired by Ivanti — Dec 2020

MobileIron pioneered unified endpoint management — combining device management, zero sign-on authentication, and mobile threat defense in a single platform, acquired by Ivanti for $872M.

MobileIron’s story is a case study in what happens when a company nails its timing. Founded in 2007 by Ajay Mishra and Suresh Batchu, the company built one of the earliest unified endpoint management platforms — right as iPhones and Android devices started flooding enterprise networks with no clear security framework in place.

By the time Ivanti acquired it for $872M in December 2020, MobileIron had over 20,000 enterprise customers — including the world’s largest financial institutions and intelligence agencies — and was generating $205M in annual revenue with a 90%+ retention rate and 80% gross margins. Those are software business numbers that hold up against almost any benchmark.

The platform combined unified endpoint management with zero sign-on authentication and mobile threat defense. The combination addressed a real gap: companies needed to manage devices, verify users, and detect threats from a single place as remote work scaled up. Today the MobileIron technology continues inside the Ivanti platform serving enterprises globally.

Chicago, IllinoisTech Media & Employer BrandingPrivate

Built In connects tech professionals with companies through editorial content, employer profiles, job listings, and the annual Best Places to Work in Tech awards.

Most job sites are built around a single transaction: post a job, fill a job. Built In built something different — a media and community platform specifically for tech professionals and the companies that want to hire them. Editorial content, employer brand pages, job listings, and annual awards that have become a genuine reference point in the tech hiring market.

The Best Places to Work in Tech lists — segmented by city, company size, and remote-first culture — carry real weight in the talent market. Companies pay to build out employer profiles and get featured in editorial content. Candidates use it to research company culture before interviewing. It works in both directions.

The editorial layer separates Built In from a pure job board. Company profiles include benefits summaries, engineering blog posts, employee spotlights, and culture statements. For growing tech companies that can’t compete on name recognition with Google or Meta, Built In’s platform offers a path to build credibility before someone walks in the door.

Milpitas, California (US HQ)Payments TechnologyPublic — BSE: RSSOFTWARE

RS Software built the core infrastructure powering India’s UPI — the world’s largest real-time payment rail — and is now bringing that same architecture to North American digital payment operators.

Most people have never heard of RS Software. But if you’ve used UPI — India’s Unified Payments Interface, the world’s largest real-time payment rail processing billions of transactions per year — you’ve used infrastructure they built. That’s a legitimately impressive credential for a company with 148 employees.

The company has spent over 3 decades building payment infrastructure — not consumer apps, not fintech startups, but the underlying rails. Their RS RealEdge product is a 3rd-generation real-time payment processing platform architected for central infrastructure operators. Open ecosystem, ISO 20022 compliant, API-first, microservices-based.

RS Software is also working on a real-time payment system for a North American digital payment operator — extending UPI-style infrastructure to new markets. The company operates across Silicon Valley, Copenhagen, and Kolkata, serving clients in the US, UK, Japan, and India.

At roughly 148 employees, it punches well above its weight class in terms of payments infrastructure impact. For anyone building or evaluating real-time payment systems, the UPI track record alone puts RS Software in a very short list of companies with proven credentials at that scale.
