Verified Synthflow AI Coupon Codes & Promo Code For Jun 2026

About Synthflow AI

Synthflow AI on the GrabOn India coupon page covers the Berlin-origin enterprise-grade AI voice-agent no-code platform operating under Synthflow GmbH and headquartered in Berlin Germany. The company was founded in 2023 by three serial-entrepreneur co-founders: Hakob Astabatsyan (Co-Founder and CEO), Albert Astabatsyan (Co-Founder and Chief Product Officer), and Sassun Mirzakhan-Saky (Co-Founder and Chief Technology Officer). The trio started experimenting with the OpenAI ChatGPT API in early 2023 to build no-code business applications and pivoted into the AI-voice-agent category as the conversational-AI market opened up. The platform builds production-ready conversational AI voice agents for inbound and outbound calls across customer support, lead qualification, appointment scheduling, and service-automation workflows.

Synthflow AI funding-and-investor stack includes a USD 20 million Series A round led by Accel announced June 2025 plus prior seed-tier funding bringing the total raised to USD 26 million. The Series A puts Synthflow AI in the top tier of the global AI voice-agent category alongside Retell AI, Vapi AI, Bland AI, and ElevenLabs Conversational AI. The Berlin-based engineering team builds the core platform with a no-code visual workflow builder, real-time personalisation engine, deep CRM integration stack, and the sub-500ms latency commitment that is competitive against the Retell-AI-around-600ms and the Vapi-around-700-to-800ms latency benchmarks tracked by the AI-voice-agent comparison community.

The Synthflow AI product catalogue covers a tiered SaaS subscription stack designed for the spectrum from individual builders to enterprise procurement. The Starter plan at USD 29 per month covers 50 included minutes on the entry-tier evaluation cart. The Pro plan at USD 375 per month covers 2,000 included minutes plus 25 concurrent calls for businesses with low-to-medium call volumes. The Growth plan at USD 750 per month covers 4,000 included minutes plus 50 concurrent calls for businesses scaling outbound campaigns. The Agency plan at USD 1,250 per month covers 6,000 included minutes plus unlimited subaccounts on the white-label-resale workflow for agencies and resellers. The Enterprise plan runs on custom pricing with volume-based rates as low as USD 0.08 per minute on the high-volume call-centre and enterprise-deployment cart. Overage rates apply after the included minutes at USD 0.12 to USD 0.13 per minute on Pro-Growth-Agency plans. A free 14-day trial covers 200 included minutes on the maiden-evaluation workflow.

Indian buyer profiles at Synthflow AI split into five cohorts. The startup-founder and small-business-owner buyer (the early-stage cohort) picks the Starter plan at USD 29 per month on the entry-tier evaluation cart for the first AI voice-agent build. The growth-stage SaaS-and-services business buyer picks the Pro plan at USD 375 per month for the 2,000-minute outbound-and-inbound campaign workflow on customer-support automation, lead-qualification, and appointment-scheduling use-cases. The Indian outbound-call-centre and BPO buyer picks the Growth or Agency plan for the 4,000-to-6,000-minute high-volume calling campaign workflow. The agency-and-reseller buyer picks the Agency plan for the white-label-resale workflow with unlimited subaccounts on the multi-client-management workflow. The enterprise-procurement buyer picks the Enterprise plan with custom-volume pricing, HIPAA compliance, SOC 2 audit, and the dedicated account-manager assignment for the regulated-industry deployment.

Synthflow AI Offer Types and Discount Tiers

The Synthflow AI coupons listed on the coupon page cluster into seven recurring offer types. Knowing which type applies to your cart helps pick the right code at checkout rather than trying every listed code in trial and error. The active codes refresh as the merchant launches new sale windows.

• Free 14-day trial (200 included minutes) (Free 14-day trial covering 200 included minutes): Synthflow AI offers the free 14-day trial on the maiden-account creation with 200 included minutes for the first-time evaluation. The free-trial-cart suits the startup-founder, the small-business-owner, the developer-evaluator, and the SaaS-product-team running the proof-of-concept build. Trial-tier converts to a paid plan on the trial-end-date with the chosen tier subscription billing.
• Annual plan saves (Save up to 20 percent on yearly billing) (Up to 20 percent off vs monthly billing on annual commitment): Synthflow AI runs the annual-plan-discount on the Pro, Growth, and Agency tiers with depth typically at 15 to 20 percent off the monthly-billing equivalent. The annual-plan-cart suits the committed-buyer with the 12-month forecasted call-volume need. The annual-plan-billing prepays the 12-month subscription and locks the per-month rate against the mid-year price-revision risk.
• Starter plan entry-tier saves (Welcome and onboarding credit) (Welcome onboarding credit on Starter plan trial-to-paid conversion): Synthflow AI offers the Starter-plan-entry-tier welcome saves on the first-time conversion from the free trial to the paid Starter plan at USD 29 per month with 50 included minutes. The welcome-cart suits the maiden-builder on the first AI voice-agent project on the entry-tier evaluation path.
• Volume-tier saves on Enterprise plan (As low as USD 0.08 per minute) (Volume-tier rates from USD 0.08 per minute on Enterprise plan): Synthflow AI runs the Enterprise-plan-volume-tier saves with rates as low as USD 0.08 per minute on the high-volume calling campaign workflow. The enterprise-tier-cart suits the BPO and the call-centre-operator buyer with the 20,000-to-400,000-plus monthly-minute commitment on the volume-based-pricing path.
• Pro-Growth-Agency overage savings (USD 0.12 to USD 0.13 per minute) (Standard overage rate USD 0.12 to USD 0.13 per minute): Synthflow AI runs the standard overage rate at USD 0.12 to USD 0.13 per minute on the Pro, Growth, and Agency plans after the included-minute pool is consumed. The overage-rate-cart suits the buyer monitoring the burst-traffic call-volume that occasionally exceeds the included-minute pool on the active billing cycle.
• Agency white-label resale workflow (Unlimited subaccounts and rebilling on Agency plan): Synthflow AI runs the Agency-plan white-label resale workflow with the unlimited subaccount creation plus the rebilling-to-clients pricing-multiplier workflow on the agency-cart. The white-label-cart suits the AI-voice-agent-resale agency, the digital-services consultancy, and the system-integrator buyer cohort building AI-voice-agent solutions on behalf of end-client accounts.
• Free integration support (200-plus pre-built connectors) (200-plus pre-built integrations on all paid plans): Synthflow AI offers the free integration support across 200-plus pre-built connectors on all paid plans including HubSpot, Salesforce, Zoho CRM, Twilio, Cal.com, Calendly, Make, Zapier, Pipedrive, Front, Slack, plus the broader CRM-and-business-tool ecosystem. The integration-support-cart suits the buyer with the existing CRM stack who wants the AI-voice-agent to read-and-write data through the established workflow.

Stacking rules to remember: the welcome code does not stack with sitewide percentage codes, prepaid order discounts stack on top of the active code on UPI and card payments, free shipping above the threshold runs automatically when applicable, and bank or card offers apply on the final billing amount after the coupon-code discount has been applied.

How to Apply a Synthflow AI Coupon on synthflow.ai

The page lists active codes including free-14-day-trial offers, annual-plan saves, Starter-plan-entry-tier saves, Enterprise-tier volume-rate saves, Pro-Growth-Agency overage-rate offers, and Agency-plan white-label-resale offers.

3. Tap Show Code or Get Deal on the chosen coupon card. The code copies to the clipboard and a new tab opens synthflow.ai with the coupon ready to paste on the checkout-or-billing page. The copy-from-the-coupon-card step is the standard activation pattern across all the listed codes.
4. Create the Synthflow AI account on synthflow.ai with the email-and-password input plus the company-and-use-case profile. The free 14-day trial activates on the first-login with the 200 included minutes. The platform opens to the no-code visual workflow builder with the template-gallery covering the customer-support, the lead-qualification, the appointment-scheduling, and the service-automation templates.
5. Build the first AI voice-agent through the no-code visual workflow builder by picking the voice from the 30-plus-language voice library, defining the agent-prompt-and-knowledge-base, configuring the CRM integration on HubSpot or Salesforce or Zoho, and testing the agent on the in-app voice-test workflow. The build-and-test cycle takes 1 to 4 hours on the first-time-build.
6. Pick the subscription plan on the synthflow.ai billing page. Starter at USD 29 per month, Pro at USD 375 per month, Growth at USD 750 per month, Agency at USD 1,250 per month, or Enterprise on custom-quote. Pick the monthly or annual billing cadence (annual-plan saves up to 20 percent on yearly billing).
7. Paste the coupon code copied from the GrabOn coupon card into the promo-code field on the synthflow.ai checkout-or-billing page. The discount line appears below the subtotal with the revised payable amount and the savings figure. Choose the payment method (USD credit-card through Stripe, ACH transfer for Enterprise, or wire-transfer for Enterprise) and confirm the order.
8. Deploy the AI voice-agent to production by linking the Twilio voice-number or the SIP-trunk integration plus the inbound-call routing-rule plus the outbound-campaign-dispatcher workflow. The production-deployment workflow takes 30 minutes to 2 hours on the first-time-deploy with the priority-support path available on the paid plans.

Copy the code from the GrabOn Synthflow AI coupons page before opening the Synthflow AI checkout. The copy-to-clipboard button on each coupon card eliminates manual typing errors that can otherwise cause an invalid-code rejection.

Bank, Card, and UPI Payment Offers

Indian banks run instant discount, EMI conversion, and cashback offers on the Synthflow AI checkout during major sale windows. Stacking a bank offer on top of the active coupon code is the standard path to the deepest effective discount.

• USD credit-card through Stripe: The standard SaaS payment path on the synthflow.ai billing page covering Visa, Mastercard, American Express, and Discover with the secure Stripe-payment-rail. The card-on-file workflow auto-renews on the monthly or annual billing cadence on the chosen plan.
• ACH transfer and wire-transfer on Enterprise plans: The Enterprise-tier ACH-and-wire-transfer payment path runs on the direct-billing invoice workflow on the dedicated-account-manager channel. The net-30 or net-60 billing terms apply on the Enterprise-tier procurement.
• Annual-plan billing: The annual-plan-billing cadence prepays the 12-month subscription and locks the per-month rate against the mid-year price-revision risk. The annual-plan saves up to 20 percent versus the monthly-billing equivalent on the Pro, Growth, and Agency tiers.
• Monthly-billing on credit-card auto-renewal: The monthly-billing cadence runs the auto-renewal-on-card workflow with the standard 14-day-trial-then-paid conversion path. The buyer can cancel the monthly subscription on the synthflow.ai account-settings page before the next billing-cycle.
• Indian buyer billing through standard Stripe-and-card path: Indian buyers on synthflow.ai pay through the standard credit-card or debit-card path on the USD-denominated billing with the bank-FX-conversion at the card-issuer rate. The Indian buyer can also use the international-payment-supported corporate-card.

• Tax and GST handling: Synthflow AI bills the USD subscription with the applicable VAT or GST per the buyer-country tax regime. Indian buyers receive the GST-invoice with the registered-GSTIN-mention on the corporate-account billing setup.
• Volume-tier custom quote: The Enterprise-tier volume-tier-rate runs on the direct-quote channel through the sales-team contact form. The custom-quote workflow covers the 20,000-to-400,000-plus monthly-minute commitment with rates as low as USD 0.08 per minute.

Bank offer eligibility, minimum cart values, and discount caps vary by sale window. Read the bank offer terms on the Synthflow AI cart page before confirming the payment. UPI offers via NPCI are typically separate from card offers and can stack with both the sitewide code and the card offer where applicable.

Understanding the service policies before placing the order avoids surprises later. Here is the policy framework for Synthflow AI.

• Free trial and account workflow: Synthflow AI offers the free 14-day trial on the first-time-account-creation workflow covering 200 included minutes.

The buyer can cancel the subscription on the synthflow.ai account-settings page before the next-billing-cycle.

The monthly-plan-cancellation stops the next-billing-cycle without prorated refund on the current-cycle.
• Service-level agreement and uptime commitment: Synthflow AI commits to the standard 99.9 percent uptime SLA on the paid plans with the custom SLA-backed uptime commitment on the Enterprise plan. The platform-status page tracks the real-time uptime, the incident-history, and the maintenance-window schedule. The platform runs on the multi-region cloud-deployment for the high-availability-and-disaster-recovery posture.
• Data privacy and compliance: Synthflow AI supports HIPAA compliance for healthcare-industry deployment, SOC 2 Type II audit certification for enterprise-procurement, GDPR compliance for European-market deployment, and the standard data-encryption-at-rest-and-in-transit stack.

Standard support response window runs 24 to 48 business hours on the email path.

The outbound-campaign-builder enforces the compliance-rule-set on the campaign-dispatch path.

How It Compares With Competitors

Synthflow AI competes in the AI-voice-agent-and-conversational-AI category against the broader brand stack including Retell AI (the latency-focused AI voice-agent platform with around 600ms response-time), Vapi AI (the API-first developer-tool-focused AI voice-agent platform), Bland AI (the strong-NLP-and-context-awareness AI voice-agent platform with code-execution-nodes and voice-cloning), ElevenLabs Conversational AI (the voice-quality-focused AI voice-agent platform from London with broader text-to-speech and voice-cloning stack), Air AI (the sales-call-automation-focused AI voice-agent platform), Cresta AI (the contact-centre-AI-platform), Replicant (the IVR-replacement AI voice-agent platform), Hume AI (the empathic-voice-AI platform), PolyAI (the enterprise-conversational-AI platform), Resemble AI Chat (the voice-cloning-plus-conversational-AI stack), Pickaxe (the AI-tool-builder), Lindy AI (the AI-agent-platform), plus the broader Indian-and-global-conversational-AI stack including Smallest.ai Atoms (the India-origin voice-AI agent platform from Bengaluru), Sarvam AI (the India-origin multilingual-voice-AI platform), Sierra AI (the customer-experience-AI-platform from former Salesforce executive Bret Taylor), Cognigy (the German-conversational-AI platform), Kore.ai (the conversational-AI-platform from Hyderabad-and-Florida), Yellow.ai (the India-origin conversational-AI-platform), Haptik (the Reliance-Jio-owned conversational-AI from Mumbai), plus the broader call-centre-software stack Five9 plus NICE inContact plus Genesys plus Talkdesk on the AI-voice-agent-bundle path. The brand differentiates on the Hakob-Astabatsyan-Albert-Astabatsyan-Sassun-Mirzakhan-Saky founder-led Berlin-D2C heritage with the sub-500ms-latency commitment that beats Retell-around-600ms and Vapi-around-700-to-800ms benchmarks, the no-code-visual-workflow-builder approach versus the developer-API-first approach of Vapi-and-Retell, the 200-plus-pre-built-integration stack including HubSpot-Salesforce-Zoho-Twilio CRM coverage, the 30-plus-language voice-library coverage, the HIPAA-plus-SOC-2-plus-GDPR compliance stack for regulated-industry deployment, the USD-20-million-Series-A-from-Accel funding backing with USD-26-million-total-raised, and the predictable-monthly-pricing-versus-pure-usage-based-pricing approach.

Coupon Not Working: Troubleshooting

Codes occasionally fail to apply at the Synthflow AI checkout. Walk through this checklist before assuming the code is dead.

• Check the cart minimum. Most Synthflow AI codes require a cart value of Rs 299 to Rs 1,00,000 depending on the code. Add one more line item if you are just under the threshold.
• Confirm the category eligibility. Welcome codes target the full catalogue but some category-specific codes apply only to selected ranges. The coupon card details the scope.
• Verify the user eligibility. Welcome codes work only for first-time buyers on the registered account. A repeat buyer trying a welcome code will hit a usage block.
• Confirm the expiry window. Codes carry expiry dates. The coupon card flags expiring-soon codes with an orange tag.
• Check payment method restrictions. Prepaid order discounts require UPI, net banking, or card payment. COD orders will not trigger the prepaid stack.
• Refresh the page or restart the cart. Sometimes the cart session times out. Refreshing or clearing the cart and rebuilding it can reset the eligibility check.
• Look for a bank offer overlap. Bank instant discount offers occasionally conflict with sitewide percentage codes. Try the bank offer or the coupon code separately to see which path gives the deeper effective discount.
• Reach Synthflow AI support. If the code is listed as verified but consistently fails, contact Synthflow AI customer support through the site chat or email with the screenshot. Support typically responds within 24 hours on weekdays.

Verdict

Best for

Startup-founder and small-business-owner buyers (the early-stage cohort) picking the Starter plan at USD 29 per month on the entry-tier evaluation cart for the first AI voice-agent build, growth-stage SaaS-and-services business buyers picking the Pro plan at USD 375 per month for the 2,000-minute outbound-and-inbound campaign workflow on customer-support automation, lead-qualification, and appointment-scheduling use-cases, Indian outbound-call-centre and BPO buyers picking the Growth or Agency plan for the 4,000-to-6,000-minute high-volume calling campaign workflow, agency-and-reseller buyers picking the Agency plan for the white-label-resale workflow with unlimited subaccounts on the multi-client-management workflow, and enterprise-procurement buyers picking the Enterprise plan with custom-volume pricing, HIPAA compliance, SOC 2 audit, and the dedicated account-manager assignment for the regulated-industry deployment.

Be careful if

Free-trial codes work only for first-time-account-creation buyers with the no-prior-account-creation history. The 14-day-trial-then-paid conversion path activates on the trial-end-date with the chosen tier-subscription billing setup. Annual-plan-cancellation refund runs on the prorated unused-portion basis within the standard 14-day refund window from the renewal date. The monthly-plan-cancellation stops the next-billing-cycle without prorated refund on the current-cycle. Overage rates apply after the included minutes at USD 0.12 to USD 0.13 per minute on Pro-Growth-Agency plans. HIPAA and SOC 2 compliance is available on Enterprise plan only. The volume-tier-rate as low as USD 0.08 per minute requires the 20,000-to-400,000-plus monthly-minute commitment on the direct-quote workflow.

Best saving move

The single deepest saving move on Synthflow AI is to time the annual-plan commitment against the New Year SaaS Annual-Plan Push window or the Black Friday and Cyber Monday window or the End-of-Year Renewal Push window when the depth lands at 15 to 30 percent off the annual-billing equivalent on Pro, Growth, and Agency tiers through the GrabOn-listed coupon path. For the high-volume BPO and call-centre buyer, the deepest move is to negotiate the Enterprise-tier volume-tier-rate as low as USD 0.08 per minute through the direct-sales contact-form on the 20,000-to-400,000-plus monthly-minute commitment. For the maiden-builder, the deepest move is to use the free 14-day trial with 200 included minutes for the first AI voice-agent build before the paid-plan upgrade.
