Chainstack is a blockchain node platform that powers global Web3 applications across fintech, DeFi, wallets, custodians, gaming, AI agents, trading, and analytics.
Chainstack's core products include Global Node, low-latency RPC endpoints for everyday workloads; Dedicated Node, single-tenant nodes with guaranteed resources for heavy workloads; reliable infrastructure built for trading bots and MEV strategies; and Unlimited Node, an add-on for unmetered request scaling. Together with Chainstack Self-Hosted for teams that need infrastructure on their own premises, these products cover every stage from prototyping to institutional-scale deployment.
Chainstack supports major blockchain networks, including Ethereum, Solana, BNB Chain, Polygon, Hyperliquid, Robinhood Chain, and other EVM-based and non-EVM chains, with elastic (auto-scaling) and dedicated node instances across mainnet and testnet. For Solana-focused trading and MEV operators, Chainstack offers the Yellowstone gRPC Geyser plugin for real-time on-chain data streaming and Jito ShredStream for low-latency transaction propagation.
Deployment options span the public cloud, preferred service providers, or fully self-hosted infrastructure, all managed through a single console with standardized node management across chains and environments. Core infrastructure features include global load-balanced RPC endpoints, blockchain data APIs, node monitoring, and request-unit-based usage tracking, keeping performance predictable and costs transparent as usage grows.
Chainstack offers a free Developer plan alongside paid Growth, Pro, Business, and Enterprise plans, so teams can start building at no cost and scale into preferred infrastructure setup as usage grows.
Teams cut time-to-market, cost, and risk with a single platform for blockchain nodes, whether in the cloud, through a preferred service provider, or self-hosted. Standardized node management across chains and environments puts reliability on autopilot and keeps performance predictable.
Operators get control and transparency, while developers get a consistent way to build and scale. Fintech companies, DeFi protocols, wallets, custodians, trading firms, analytics platforms, and Web3 service providers running fleets use Chainstack as the fastest way to run reliable, predictable blockchain nodes at scale.

Mentornity is mentoring and coaching program software for organizations that run structured programs and need to show what came of them.
It covers the full cycle: enrolment, matching, scheduling, session tracking, feedback and reporting. Each program runs under its own branding and its own rules, and administrators see participation as it happens rather than at the end of the cycle.
MATCHING
An algorithm scores every possible pair against criteria the program defines, each with its own weight, and removes pairs that fail a mandatory rule. Administrators review suggestions side by side and approve them individually or in bulk. Programs can also assign pairs manually, or let participants choose their own mentor. Group programs and open mentor pools are both supported.
SCHEDULING
Mentors publish their availability, mentees book within it, and sessions sync to Zoom, Microsoft Teams or Google Meet. Reminders are sent automatically before and after meetings.
MEASUREMENT
Surveys and forms can run at any point in a cycle. A program health score tracks participation, meeting frequency and completion against each program's own targets, and flags programs that are drifting before the cycle ends.
CERTIFICATES
Issued automatically on completion, with per-program templates and role-specific wording.
ADMINISTRATION
Role-based access, six interface languages, white labelling on a custom domain, in-app messaging and announcements, and a direct support channel between program administrators and the Mentornity team.
WHO USES IT
Universities and alumni offices, corporate learning and development teams, startup accelerators and incubators, professional associations, and NGOs, across Europe, North America and Türkiye.
PRICING
Free for up to 10 users, with no expiry and every feature enabled. Paid plans start at $289 per month with no setup fees, and scale by participant count. Universities, schools and student programs receive a 50% discount. SSO is the only paid add-on.
Running mentoring programs since 2015.
